Press Release: "Car of the Year 2010: Opel once again on the podium"
Rüsselsheim. One year after the Insignia has won the 2009 competition, the new Opel Astra has taken the third place in the Car of the Year 2010 *. It is the third Opel model to win a spot on the podium of the most respected car competition in Europe in four years.
“Frankly, winning two years in a row would have been an absolute exception. Surely, the new Astra has been recognized as being the best new car in the compact class – the most disputed and most popular in Europe with over 25% of all car registrations. This honor makes us very proud: It’s a strong appreciation of the work of the Opel/Vauxhall team,” says Alain Visser, Vice President Sales, Marketing & Aftersales for Opel/Vauxhall. “I thank the Car of the Year jury members for praising the sleek design and innovative technologies we offer in our new compact car.”
The Opel Insignia was named Car of the Year in 2009. In 1985 the Kadett won; and in 1987 the Omega grabbed the title. The Corsa celebrated its podium finish in 2007.
The Car of the Year is an award given by 59 senior motoring correspondents from 23 European countries. 33 contenders entered this year’s competition. The jurors voted on such criteria as design, comfort, safety, economy, handling, performance, functionality, environmental requirements, driver satisfaction, and price. Technical innovation and value for money are particularly important factors for COTY and they are an Opel strong point.
The new Opel Astra, which premiered at the Frankfurt Motor Show in September, follows in the Insignia’s footsteps by hallmarking Opel’s philosophy of combining German precision with sculptural design. For the first time, innovative technologies like adaptive lighting and the Opel Eye camera system are accessible to the compact class which is the most popular segment in the automotive market.
The Opel Astra will hit dealerships in Germany on December 5 with a line-up of eight engines: four gasoline engines and four direct-injection turbo-diesels, all with extremely competitive CO2 emissions. Due spring 2010, the 95 hp diesel ecoFLEX variant will offer remarkably low combined fuel consumption of 4.2 l/100 km and 109 g/km CO2 at an affordable price.

Press Release: New Opel Astra receives five-star Euro NCAP safety rating
Rüsselsheim. The European new car safety assessment organization, Euro NCAP, has awarded the new Opel Astra five stars for safety – the top rating for new tough regulations that took effect this year.
Euro NCAP gave its highest points ever awarded for Astra’s active head restraints which protect against whiplash. This is especially important because whiplash is the most common occupant injury suffered when a car is hit from behind. Opel’s active headrest system, an integral part of the brand’s industry-leading seats, is in itself a technical innovation. It is completely reversible, requiring no dealer reset after a rear-end collision.
The Astra scored very well on its front passenger occupant protection in a frontal impact. NCAP also added points because Electronic Stability Controlplus – a computerized technology that improves a vehicle’s stability by detecting and minimizing skids – is standard on all variants in all of the 27 countries which use Euro NCAP ratings as well as Norway and Switzerland.
Euro NCAP now releases one overall star rating with a maximum of five stars. The number of stars reflects how well a vehicle performs in four areas: adult protection, child safety, pedestrian protection and safety assist. The score is calculated by weighing points in the four areas while still ensuring that no section is neglected “Opel designs, engineers and builds some of the safest cars in the world. That isn’t opinion, it is fact confirmed by independent safety organizations,” says Hans Demant, managing director of Adam Opel GmbH.
The body structure and occupant restraint systems on the Astra are prepared to meet current and anticipated crash safety standards not just in Europe, but all over the world, offering optimal protection in real life situations.
Among the many safety features on the Astra are new advanced dual seat belt pre-tensioners, which help achieve prevent injury because they keep occupants’ hips in place during a crash, eliminating the need for expensive, heavy knee airbags and making way for more occupant storage space.
Other passive safety equipment found on the Astra includes six airbags, smart seatbelt reminder system and a passenger airbag switch-off to allow child seats to be safely placed in the front. Further safety equipment includes ABS with numerous assistance functions, tractions control, new generation ESPPlus, adaptive brake lights, Adaptive Forward Lights (AFL+) and the Opel Eye camera system.
Extremely rigid passenger compartment aids outstanding crash performance
Passive safety on the Astra starts with a rigid passenger cells that is primarily made from high-strength steel that Opel engineers designed for the least deformation and highest survival space possible in case of a crash. The front and rear of the cabin are surrounded by crumple zones that deform and protect in a safe, controlled manner.
The front end has a three-load path design, including the chassis sub frame, which can withstand impact even in the case of a high speed, front impact collision by spreading the energy produced from a crash. For side impact protection, where there is little leeway to engineer a substantial crumble zone, the stiff side body structure is made to spread loadings. Doors are made with ultra-high strength steel reinforced beams that are now mounted diagonally so that the B-pillar, itself made of the highest grade steel, side sill and floor and the roof cross-members work together to spread the load.
Engineers have also worked to continually improve pedestrian protection by, in part, providing adequate clearance for all hard points under the hood and adopting a hood that considers both stiffness and protection against head impacts from pedestrians. The Astra scored maximum NCAP points in one subcategory because its bumper with energy absorbing foam materials protects against lower leg injury across nearly the entire vehicle width
Keeping children safe
In the frontal and side impacts, the Astra scored maximum points for protection of the 3-year dummy during NCAP testing. This is achieved, in part, through specially developed Opel Child Seats which protect against both front and side impacts. In addition to the ISOFIX lock, Opel Child Seats come with an extra top tether that is standard so that the seat is safely anchored to the back of the rear seat. ISOFIX child seat features are located on outer rear seats. The front passenger airbag can be switched off so that child seats can be safely used there as well.
Coherent Safety Strategy
Opel engineers have synchronized active and passive safety systems on the Astra for a coherent safety strategy. Many of these state-of-the-art features lead the compact class segment, ensuring best possible safety.
Features which assist the driver include:

- Opel Eye – a lane departure warning and traffic sign recognition system
- Automatic Lighting Control
Active safety features which give the Astra excellent handling and control to help prevent accidents from happening include:
- Electronic Stability Controlplus, which intervenes on up to three wheels.
- FlexRide, Opel’s mechatronic chassis system with Adaptive Stability Technology helps the car adjust automatically to prevailing driving conditions
- Brake Assist
- Traction Control with engine and brake intervention
In addition to the rigid passenger compartment and six airbags, other passive safety features on the Astra are:
- Active head rests to prevent whiplash
- Dual seatbelt pre-tensioners,
- Belt load limiter that releases seatbelts to limit pressure on the chest
- Pedal release system that reduces the danger of driver leg injuries
- Anti-submarining ramps on all seats, so that occupants can’t slide under the seatbelts
- Energy- absorbing steering column
Warning and security systems are:

Press Release: "Opel Corsa: New heart, new muscles – everything under the skin is new"
Rüsselsheim. Come January 2010, the Opel Corsa gets a complete re-make, with major engineering changes so numerous that the super-mini family is reshaped. A re-vamped powertrain line-up, chassis improvements and a steering recalibration will give the Corsa better performance and greater fuel economy – as well as superb passenger comfort, excellent handling and exciting driving dynamics.
The Corsa stays faithful to its exciting design, with sporty contours and one of the roomiest and most flattering interiors in its class. It also features innovative technologies that remain exceptional in the small car segment. These include the halogen AFL curve and cornering lights, a heated steering wheel and the integrated bicycle carrier system FlexFix which is unique to Opel. The Corsa, which accounts for some 30 percent of Opel/Vauxhall total sales, is available in two distinctly different variants: the coupé-like three-door and the family friendly five-door model.
Much lower fuel consumption and increased output in the gasoline engine line-up
The Opel Corsa boasts a new gasoline engine line-up that fully complies with Euro 5 standards. All engines have been re-worked to offer more torque while featuring up to 13 per cent lower fuel consumption and CO2 emissions. Both the 1.2- and 1.4-liter Twinport variants are each available in two versions with different outputs. Every country selects and offers customers the variants that suit the needs of their region. Some may decide to go for optimal fuel efficiency; other may want to balance it with more performance.
The most popular gasoline powertrains (the 1.0 to 1.4 liter with manual and Easytronic transmissions) now have fuel consumptions between 5.0 and 5.5 liter/100 km, with maximum CO2 emissions of only 129 g/km.

The most popular gasoline powertrains (the 1.0 to 1.4 liter with manual and Easytronic transmissions) now have fuel consumptions between 5.0 and 5.5 liter/100 km, with maximum CO2 emissions of only 129 g/km.
Performance and efficiency improvements were made possible through a number of technical changes:
- A new oil pump optimizes oil pressure and reduces frictions, lowering fuel consumption.
- A newly developed double camshaft phaser on the 1.2- and 1.4-liter engines improves the combustion process, allowing increased power and torque.
- A new management of the thermostat reduces the engine warm-up phase, further lowering fuel consumption and emissions.
- A shift-up indicator in the cluster informs drivers how they can save fuel.
In the 65 hp segment:
The entry level 1.0 liter 3-cylinder now develops 48 kW/65 hp and 90 Nm. This compares with the previous generation, with 44 kW/60 hp developing 88 Nm. At the same time, fuel consumption and emissions on the new entry level engine have been reduced by 13 per cent, at 5.0 liter and 117 g/km (from 5.6 liter/100 km and 134 g/km). This makes the Corsa 1.0 liter the cleanest of all gasoline-powered super-minis.
At this level of power, Opel also offers a new variant of the 1.2 liter 4-cylinder with 51 kW/70 hp and a generous 115 Nm. This is a 5 Nm increase from the previous 59 kW/80 hp variant. Again, fuel consumption and CO2 emissions measure 5.3 liter/100 km and124 g/km.
In the 85 hp segment:
At the next level, a new version of the 1.2 liter engine now offers 63 kW/85 hp and 115 Nm of torque. This is compared to 80 hp and 110 Nm on the current Corsa 1.2 liter. At the same time, the new 1.2 liter engine has an 11 percent reduction in fuel consumption and CO2 emissions on the manual transmission and a 13 percent cut with the Easytronic manual automated transmission (5.1 liter/100 km and 119 g/km CO2 vs 5.8 l and 137 g).
In the same category, an alternative engine with more torque is also available: A new generation of the acclaimed 1.4 liter engine with a capacity of 1,398 cc (vs 1,364 cc) due to a 2 mm longer stroke now develops 64 kW/87 hp and generous 130 Nm of torque. Its fuel consumption and CO2 emissions, however, do not exceed 5.5 liter/100 km and 129 g/km CO2 – another 12 percent improvement compared to the previous 59 kW/80 hp 1.2 liter with a close ratio manual transmission.
In the 100 hp segment:
A second version of this new 1.4 liter engine is also offered with 74 kW/100 hp and 130 Nm of torque – providing more vim and vigor than the previous generation’s 90 hp and 125 Nm, thus with a 12 percent improvement in fuel consumption and CO2.. Requiring only 5.5 liter /100 km (129 g/km CO2), it provides with a top speed of 180 km/h, and accelerations from 0 to 100 km/h in 11.9 seconds.
The sporty versions:
The top-of-the-line turbo 1.6 liter gasoline engine from the Corsa GSi (110 kW/150 hp) and OPC (141 kW/192 hp) versions also offer a significant improvement in fuel consumption and CO2 emissions. It is achieved through optimizing the engine calibration for Euro 5 and 95 RON (GSi) or 98 RON (OPC) fuels. The average fuel consumption for both variants is now lowered by 9.5 percent to 7.3 l/100 km with CO2 emissions at respectively 171 g/km on the GSI and 172 g/km on the OPC.
Transmissions offer a choice between optimal fuel economy or greater performance
In many cases, the new gasoline-powered Corsa offers a choice between close- and wide- transmission ratios. Traditionally, close ratio transmissions are matched to gasoline engines for sportier, higher rpm gear changes, while wide ratio transmissions in diesel vehicles compensate for a narrower rpm bandwidth and provide more economical driving.
Because all gasoline engines have improved their torque values, especially at lower rpm, it has been possible to also match them with wide ratios transmissions. As they now have the choice between transmissions with performance-oriented short- or economy-focused wide ratios, Opel national entities can best adapt their offer to the driving needs and tastes of their customers and the specific tax regulations in their market.
The entry level 1.0 liter 3-cylinder now develops 48 kW/65 hp and 90 Nm. This compares with the previous generation, with 44 kW/60 hp developing 88 Nm.

Diesel engines: New top-of-line 1.7 CDTI 130 hp with 300 Nm and 95 hp ecoFLEX
1.7 CDTI:
The top-of-the-line 1.7 CDTI diesel engine in the Corsa range also gains output and torque while reducing its appetite for fuel. Power increases from 92 kW/125 hp to 96 kW/130 hp while the torque value rises from 280 to 300 Nm at the same engine speed. Emissions, on the contrary, fall 9 percent – at a remarkable 118 g/km CO2 from 130 g/km CO2 for the 3-door version. The Corsa 1.7 CDTI now reaches 200 km/h (5 km/h more than the previous generation) and sprints from 0 to 100 km/h in 9.5 seconds (versus 9.9 seconds on the previous generation). Due to its increased torque, it now accelerates from 80 to 120 km/h in 5th gear in 9.3 seconds only (compared with 10.4 seconds previously).
While making it Euro 5 compliant, Opel engineers bettered the performance of the 1.7 CDTI by adding a new turbo charger with an actuator position sensor providing a more precise control of the boost pressure. To reduce fuel consumption, they developed a fuel injection system that improves the combustion process; they also switched to low voltage glow plugs that reduce the load on the generator when the engine warms up. A new, lighter intake manifold also helps the Corsa shed weight and an up-shift indicator assists the driver in adopting an economical driving style.

The new, lowest emitting Corsa ecoFLEX variant is now powered by a sophisticated, 70 kW/95 hp 1.3 CDTI diesel engine boosted by a turbo with a variable geometry. It is packed with 27 percent more power than the previous generation Corsa ecoFLEX even though fuel consumption and CO2 emissions are slashed by some 10 percent. With its 190 Nm of torque available between 1750 and 3250 rpm, this Corsa ecoFLEX needs only 3.7 l/100 km, releasing just 98 g/km CO2 as a three-door. The five-door Corsa emits 99 g/km. A particulate filter is standard. An up-shift indicator on the dashboard helps the driver optimize fuel economy.
This version replaces the 1.3 CDTI ecoFLEX (55 kW/75 hp) with 109 g/km CO2 which was only available in 3-door version.
1.7 CDTI:
The top-of-the-line 1.7 CDTI diesel engine in the Corsa range also gains output and torque while reducing its appetite for fuel. Power increases from 92 kW/125 hp to 96 kW/130 hp while the torque value rises from 280 to 300 Nm at the same engine speed. Emissions, on the contrary, fall 9 percent – at a remarkable 118 g/km CO2 from 130 g/km CO2 for the 3-door version. The Corsa 1.7 CDTI now reaches 200 km/h (5 km/h more than the previous generation) and sprints from 0 to 100 km/h in 9.5 seconds (versus 9.9 seconds on the previous generation). Due to its increased torque, it now accelerates from 80 to 120 km/h in 5th gear in 9.3 seconds only (compared with 10.4 seconds previously).
While making it Euro 5 compliant, Opel engineers bettered the performance of the 1.7 CDTI by adding a new turbo charger with an actuator position sensor providing a more precise control of the boost pressure. To reduce fuel consumption, they developed a fuel injection system that improves the combustion process; they also switched to low voltage glow plugs that reduce the load on the generator when the engine warms up. A new, lighter intake manifold also helps the Corsa shed weight and an up-shift indicator assists the driver in adopting an economical driving style.

Chassis and steering have been optimized for even more comfort and fun to drive
Already praised for its dynamic qualities and the fun it delivers while driving, the Corsa receives a number of chassis and steering upgrades.
Steering:
Opel has optimized the steering on all Corsa models. The software controls for the Electronic Power Steering (EPS) have been re-tuned and the engineers have installed a new yoke liner in the steering gear for reduced friction. Overall, these measures provide improved feedback and precision with increased on-center feel and stronger return to the middle position after a curve or any input given to the steering for lane changes. Corrective maneuvers result in improved straight-ahead stability.
Chassis:
The changes to the suspension apply differently to the Corsa models.

Chassis:
The changes to the suspension apply differently to the Corsa models.
- On all models except OPC, engineers have modified the rear axle by rotating the torsion profile of the compound crank by 20° - from 15 to 35°. This results in improved stability in lane-change maneuvers.
- On the comfort chassis (from all models except the Sport trim as well as the GSi and OPC versions), dampers in the front and the rear have been re-tuned to further improve the ride comfort without compromising the driving dynamics. At the same time, engineers have opted for new, softer jounce bumpers in the front struts. The ecoFLEX models also get softer jounce bumpers in the rear. All diesel variants are also equipped with new, softer front springs.
- All Corsa equipped with the comfort chassis received a new front anti-roll bar, whose diameter has been increased by 1 mm.
- The mountings of the stabilizer have been re-designed on all variants, resulting in reduced body roll, and compensating for the softer set up of the suspension.

Press Release: Winter weather can be frightful, but driving an Opel can be delightful
Rüsselsheim. As winter sports fans look forward to – and others wait nervously for – the first snowfall, now is the time for drivers to prepare for slippery, treacherous roads in the cold months ahead. Drivers need to prepare their cars and start thinking about changing the way they drive. Proper planning, practical Opel features and accessories along with a good dose of foresight can take much of the danger out of winter driving.
As a rule, avoid abrupt braking, gear changes and steering maneuvers on slick roads. Instead, drive slower, more defensively and maintain distance to vehicles ahead. Release the clutch carefully or engage second gear when starting off to avoid wheel spin. Select the winter program on automatic transmissions, if your car offers it.

Opel’s common sense tips for unpredictable weather
Tips for winter-proofing the car:
- Change to winter tires in good time. Their specific rubber composition and special tread has a better grip on snow and ice that ensures good traction and a shorter braking distance.
- Make sure windshield wipers are clean and smooth and water jets are unobstructed. A quality anti-freeze should be formulated to -20 degrees Celsius.
- Replace old batteries. Opel batteries feature excellent cold-start capability, are maintenance-free and offer full-power performance even for many short trips.
- Check that lighting works faultlessly. Regularly clean the headlamp housings – with xenon and some halogen systems, the high-pressure cleaning function takes care of this. A winter check up at any Opel Service Partner can help.
- Clear the whole car of ice and snow before setting off. Remember to also clean the roof to prevent flying snow from endangering following cars or sliding forward and obscuring the driver’s visibility during heavy braking. All windows, particularly the windshield, must be completely free of ice. The most effective way to clear windows is with an ice scraper or diluted antifreeze windshield washer fluid.
Safe braking and lighting key to safety in winter
- Test brakes when first setting out to get a feel for the road conditions – but check in the rear-view mirror first.
- Should the car start to swerve on a snow-covered road, do not brake suddenly. Instead, engage the clutch to give the wheels more cornering stability, counter-steer and brake lightly if needed.
Opel cars are already well-equipped for the winter. For example, the new Astra features ABS with cornering brake control, traction control and ESPPlus as standard.
Lighting is important: Drivers must be seen as much as they need to see the road and possible obstacles. Daytime running lamps ensure optimal visibility and adaptive braking lights warn the car behind by blinking when ABS engages.
In the winter months, many commuters in northern and central Europe drive almost solely in the dark, making optimal lighting extremely important. Opel has been an industry leader in lighting systems with the introduction of Adaptive Forward Lighting in all segments. It offers affordable halogen curves and turning lights in the Corsa (400 euros in Germany) and the Meriva for instance, or the most sophisticated bi-xenon AFL+ with nine lighting functions, such as adverse weather light and high beam assist on the new Astra and the Insignia (1,250 euros in Germany).
Enhanced all-weather stability with Opel all-wheel drive systems
Four-wheel drive can make a world of difference – and not just on snow-covered mountain passes. It also aids drivers in wet autumn weather on slippery roads. The Opel Insignia 4x4 and Antara four-wheel drive boast very stable handling performance and optimum traction.
The Insignia with FlexRide and Adaptive 4x4 brings extra driving stability even before the electronic stability program (ESP) kicks in. The FlexRide premium mechatronic chassis ensures optimal road holding, while two electronically controlled limited slip differentials send power to the wheels with the best traction. Drivers can turn off the traction control if they need to free a vehicle stuck in deep snow. Turning off the traction control (which can be done by using the ESP button) allows desired wheel spin that helps the vehicle exit a slippery spot.

Turning off the traction control (which can be done by using the ESP button) allows desired wheel spin that helps the vehicle exit a slippery spot.
- Even with four-wheel drive vehicles, driving behavior must be adjusted to prevailing weather conditions. Good traction should not be a temptation to drive aggressively.
- Sometimes even the best winter tires aren’t enough – for instance in alpine ski areas. In these cases, snow chains are the answer. It is important to fit the chains before beginning an uphill drive and remove them as soon as the road is clear otherwise the chains, tires and road can be damaged. It is a good idea to practice fitting snow chains at least once before they are actually needed. Opel offers chains specifically designed for its vehicles starting at 76.00 euros in Germany.
Practical Opel features and accessories enhance winter safety and comfort
Safety and comfort in the cabin are just as important. Heated seats and a heated steering wheel are a must for those cold winter mornings. Also available for those whose car stays outside in cold climates, a fuel-fired auxiliary car heater system with remote control and a timer can be an asset. An air conditioner, too, ensures faster fog-free windows by dehumidifying the air.
As driving in the dark is notoriously tiring, drivers welcome the relief of the Opel’s new back-friendly ergonomic seats with the seal of approval from AGR (Action for Healthy Backs), which are available in the new Astra for 500 euros in Germany. They are standard in the Insignia Sport version and optional in other variants. They can be ordered with multi-stage seat heating for the driver and front passenger.
With the right preparation, winter doesn’t have to be a chore. Winter sports enthusiasts appreciate the wide selection of Thule roof boxes available for the new Astra and many other Opel models.
It is important to properly secure all loads, as skis and other equipment can turn into lethal objects if dislodged by the wind, speed or vibrations or in the event of a collision.
In the trunk, a durable, semi-rigid molded Hard Cargo Tray can hold snowy boots and other winter gear to keep the rest of the luggage compartment dry. When the winter outing comes to an end, the tray can be easily removed for cleaning – ready for the next adventure in the snow.

2010 Lotus Evora starts at $73,200
Now that the new Lotus Evora has been successfully launched in Europe, it's time to start delivering the new model to U.S. Lotus dealers. Production of U.S.-spec cars will be starting shortly so Lotus has finally defined a price point for the car beginning at $73,200. For that price you get the 276-hp Toyota-sourced 3.5-liter V6 and a 6-speed gearbox.Unlike the minimalist Elise and Exige, the Evora is fully trimmed out in a fashion someone might expect of a $73,200 car, including hand-stitched leather from Muirhead and aluminum trim that hints at the structure under the plastic skin. The tiller is adjustable for reach and rake, which, along with the larger size of the car, should make getting in and out much easier than in the Exige. Final EPA numbers haven't been published yet, but the Evora is expected to top 30 mpg on the highway while the 0-60 time will be just 4.9 seconds.
If you haven't yet seen the Evora in person, Lotus has just started a 44-city dealer open house tour around the U.S. The full schedule is in the press release after the jump.
Volkswagen Citi Golf Mk1 Limited Edition
Volkswagen has ended production of the Golf Mk I model in South Africa and announced that a limited edition of 1,000 Citi Mk1's (based on the Golf I) will be made as a commemorative series. The Golf I was introduced in South Africa in 1978. In 1984 the Citi model, based on the Golf Mk I, went into production at VW's plant in Uitenhage as an entry-level vehicle slotted beneath the subsequent generations of the ever-growing Golf model. 377,484 Citi's have been produced in South Africa over the last 25 years.
The limited edition Citi Mk1 will be fitted with a 1.6 liter petrol/gasoline engine with 74kW/100 hp. It will come in only two colors, black and shadow blue metallic. Each unit will carry its series number on the dashboard and on the Mk1 logo on the exterior. The Citi Mk1 will sell for R113,500 (10,280 euros).
It has been strongly rumored that the Citi will be replaced by the 2009 VW Gol - a model Volkswagen produces in Brazil.
See press release for further Citi Golf Mk1 Limited Edition details.
5,000 km review of my Opel Insignia 1.6T Sport
My Insignia has now more than 5,000 km on the clock and it's time for a short review.
The main thing is that I am really satisfied with the car and there is absolutely no regret in my selection. Considering that the Sport trim level costs around €24-25K, it's definately a very good value for money.
Build and material quality is very good, with the only downsides being a rattle at the bottom of the navi screen and a couple of big panel gaps on the outside. In terms of ergonomics and functionality, no problems have been noticed.
Build and material quality is very good, with the only downsides being a rattle at the bottom of the navi screen and a couple of big panel gaps on the outside. In terms of ergonomics and functionality, no problems have been noticed.
Performance is good, as expected from a car with 180 hp, but bare in mind that it's almost 1.5 tonnes heavy and 4th, 5th and 6th gear rations are rather tall.
In terms of reliability so far, everything works fine. Only one of the flaps of the cup holder was replaced under warranty, but I bet that it was damaged over here prior the delivery. The only complicated thing about this car is the firmware updates. Those are available from Opel, but it's down to the main importer to decide which ones are mandatory. Getting the rest of them it's either up to the kindness of the dealer or a matter of paying.

Getting the rest of them it's either up to the kindness of the dealer or a matter of paying.
This situation however became irritating, due to the fact that there was an issue on all 1.6T models with a very noticeable vibration when the engine was being switched off. This was solved with some updates, but finding a dealer to do it was a difficult task, since there was no notification sent to the dealers by the main importer. When the updates were installed, the engine response changed (now it seems to be smoother with no lag at all) and with no vibration anymore... but then cruise control stopped working as the technician cocked up the brake pedal sensor! A calibration of the sensor was required, after the updates, but because he was ignorant, not only the problem with the cruise control came up, but also the brake lights did not work!!!
Last but not least, original navi maps were completely crap and YM2010 cars are equipped with much better ones. I am not sure if the main importer has decided on how customers with the old maps will get the new ones installed, but thanks to a good salesman, a lot of people managed to get them at a meeting of the club...

Opel/Vauxhall is developing a small SUV, based on Corsa. The new model will be released in 2011 and will feature a slightly higher ride and widened track .
The small SUV category includes the Skoda Yeti and the upcoming Mini Crossman.
An entry level two-wheel drive version, as well as a flagship hybrid model are also thought to be in the line.
Information on Body Control Module (BCM) & Engine Control Module (ECM)
ΒCM means Body Control Module. Its the computer that control a lot of things in the car. When the BCM goes bad little things act quirky. Doors not unlocking, lights come on for no reason, car chimes and wont stop, rear hatch unlocks for no reason. Usually if you disconnect the battery for a bit it resets it and cures some of the faults.
While there are many different types of body control modules, they are generally alike, connecting sensors, switches and automatic reactions together in one computer system. These components are divided into inputs, such as sensor data about heat or speed, and outputs, or ways in which the body control module computer responds to control the vehicle's electronic functions. Inputs and outputs are further divided into analog and digital types of information, analog signals being used with modules that may change continuously (such as oil pressure) and digital signals being used for modules that can simply be on or off (like the headlights or the oil indication light).
Computer Tasks
The body control module computer itself performs many of the functions of a normal computer, including storing data, using RAM, and sending or receiving radio waves. It is the computer's job to regulate many of the systems and troubleshoot all of its component modules. Some modules are set by timer, which the the computer digitally keeps track of, while other modules like the anti-theft alarm need to be kept active even when the car is turned off. The body control module computer can also be in charge of keeping track of mileage and CO2 output.
When troubleshooting, a mechanic can often get pointed to the right area by the body control module system, which sends out a code that shows what module is not responding. At times the body control module computer can even diagnose itself and report specific problems.
The Body Control Module (BCM) supplies vehicle occupants with visual and audible information and controls various vehicle functions, To provide and receive information, the module is interfaced to the vehicle's serial bus communications network, the Chrysler Collision Detection (CCD) bus. This network consists of the powertrain control module (PCM), the Transmission Control Module (TCM) , the electro/mechanical instrument cluster (MIC) , the Airbag Control Module (ACM) , the Compass/mini-trip module and the Controller Antilock brake Module (CAB). The BCM is operational when battery power is supplied to the module. Ignition switch power is needed for ignition switch functions.

• Windshield wipers / washers (front and rear)
ECM (ENGINE CONTROL MODULE)
A car has at least one computer, but most have an engine control module (ECM), a body ride control unit, an ABS computer and a climate control computer. How many of these computers depend on the vehicle year, make and model and the options the vehicle has. If the vehicle does not have ABS brakes, it will not have an ABS computer. If the vehicle does not have climate control, it will not have a climate control computer.
Computers
The main computer is the engine control module. This may also be called the programmable control module. This computer takes its inputs and outputs through the various sensors on a vehicle. Sensors that give input give the computer information to send back to the engine via the output sensors.
Sensors
Some of the sensors include a mass air flow sensor, a coolant temp sensor, cam sensor, crank sensor, idle air control motor, EGR valve, throttle position sensor and a knock sensor. Each sensor has its own job in telling the computer what the conditions are such as air quantity and quality, temperature of the coolant and where the throttle is. The computer uses this information to make infinite changes to the air-fuel ratio, turn the fans on or off and change the idle speed and injector timing, along with many other things needed to run the vehicle.

The computer uses this information to make infinite changes to the air-fuel ratio, turn the fans on or off and change the idle speed and injector timing, along with many other things needed to run the vehicle.
Diagnosis
This part of the vehicle's running system is diagnosed by the engine control module. It lets you know when something is not working by turning the "check engine" or "service engine soon" light on. The ECM sends "codes" that turn the light on. A scanner is hooked up to the port under the driver's side dash so that the codes can be read. Because you cannot visually see if a sensor is bad, you must rely on the ECM to tell you this information. The scanner will tell you which sensor is out of range or not working at all.
The ECM cannot diagnose itself. If an ECM goes bad, the vehicle may run badly or not at all. If the vehicle is running badly, a sensor could be out of range or bad, or the computer could be bad. When you hook up the scanner, you may get codes that do not exist or you may get codes that exist but do not make sense. This is a good sign that the computer itself is not working properly and should be replaced.
Conclusion
When you are working with the computer, extreme care must be taken. A friction shock from your fingers can damage the computer. Ground yourself before touching the computer. Most of today's computers must be programmed for the specific vehicle (getting "flashed"). You will need the VIN and the mileage of the car in addition to the numbers on the outside of the computer. The staffers at the auto parts store or the dealer should know that the PROM must be removed from the old computer and put into the new computer prior to "flashing" the computer. If they neglect to move the PROM or they say they will "flash" the computer without having your old computer, be sure to remind them that they cannot flash it without the PROM.
