OFFICIAL PRESS RELEASE
Stuttgart – Mercedes-Benz is continuing its commitment to further reductions in fuel consumption and exhaust emissions with new products in eight model series which will take centre stage at this year's Geneva Motor Show. The Vision GLK BLUETEC HYBRID lends further substance to the Stuttgart-based automotive manufacturer's claim of developing the world's most efficient and cleanest-running passenger car engines. Equipped with a state-of-the-art diesel-hybrid system, the study version of the forthcoming Mercedes off-roader excels with NEDC fuel consumption figures of a mere 5.9 litres per 100 kilometres, and complies with even the strictest emissions regulations courtesy of the highly efficient BLUETEC treatment process.
The Vision GLK BLUETEC HYBRID gives a further foretaste of the new off-roader from Mercedes-Benz, whilst providing a fresh demonstration of the ingenious BLUETEC emission control technology's remarkable efficiency. The four-cylinder diesel engine fitted in the study combines with a hybrid module to deliver a total output of 165 kW/224 hp and 560 Newton metres of torque. The NEDC fuel consumption of the Vision GLK BLUETEC HYBRID makes even more impressive reading: a mere 5.9 litres for every 100 kilometres. This enables the Mercedes study to achieve a lower CO2 emission figure than any other model in the SUV market segment in the world: just 157 grams per kilometre. As a result of the highly efficient BLUETEC emission control with AdBlue injection, the GLK BLUETEC HYBRID is able to comply with the world's toughest exhaust emissions standards, such as BIN5 in the US and EURO 6.
In the hybrid drive train of the Mercedes study, a completely new four-cylinder CDI diesel unit with a displacement of 2.2 litres acts as the internal combustion engine. The technical highlights of this extremely compact and refined CDI unit with a geared camshaft drive mounted on the flywheel side include latest-generation common-rail direct injection with an injection pressure of 2000 bar and innovative piezoelectric injectors, as well as a two-stage turbocharger system. The compact hybrid module – a disc-shaped electric motor between the CDI engine and the automatic transmission – improves both the environmental compatibility and the effectiveness of the drive system.
The electric motor acts as both a generator and starter, and offer a two-pronged advantage: firstly it contributes decisively to fuel economy, and secondly it significantly enhances driving pleasure by virtue of the boost effect. The electric motor backs up the internal combustion engine during the fuel-intensive acceleration phase by contributing its maximum torque of 160 Newton metres. As a result the occupants experience an effortless rush of power right from the start.
In addition the system features a comfortable start-stop function which switches the engine off in certain circumstances – for example when the car is stopped at traffic lights. When it comes to braking, the procedures are reversed: the electric motor now acts as a generator, feeding the electrical energy obtained from the recuperation process into an efficient yet compact lithium-ion battery. This energy can be retrieved when needed – for the next "boost" phase, for example. All these processes take place fully automatically, thanks to intelligent drive management.
With the VISION GLK BLUETEC HYBRID, a distinctive character is entering the SUV stage whose special appeal lies in a combination of the angular original design of the legendary G-Class and the typical design features of today's Mercedes-Benz passenger cars. Crisp lines and large taut body surfaces come together with the bodyshell characteristics of practical off-roaders, such as short overhangs, an upright front end, slim A-pillars, a steep windscreen and tight roof contours. An excellent view of the vehicle body and good all-round visibility go together with the raised seating position to enhance day-to-day suitability and ensure relaxed driving.
The Vision GLK BLUETEC HYBRID demonstrates how outstanding performance could be paired with highly economical fuel consumption in the future – a combination that need not be confined to the forthcoming GLK-Class.
