Mercedes Debuts 40mpg GLK BlueTec Hybrid Diesel SUV

Mercedes-Benz has unvieled the Vision GLK BLUETEC HYBRID at the 2008 Geneva Motor Show. The Vision GLK BLUETEC HYBRID uses the new BLUETEC four-cylinder diesel engine generation with a hybrid module. This combination generates an overall output of 165 kW/224 hp, and a torque of 560 Nm. Superior performance can be taken as read in view of these figures. And yet the Vision GLK BLUETEC HYBRID returns a fuel mileage of 40 mpg.

With its TrueBlueSolutions strategy, Mercedes-Benz is preparing the way for the introduction of the world’s most economical and clean vehicles. As in the case of the VISION GLK BLUETEC HYBRID, ultra-modern and efficient diesel engines with innovative BLUETEC emissions control, hybrid modules and intelligent energy management are among the centrepieces of this trailblazing generation of drive systems. The study for this compact characterful SUV has a combined output of 165 kW/224 hp and generates a combined torque of 560 newton metres, the world’s highest in this class. This enables the VISION GLK BLUETEC HYBRID to accelerate from zero to 100 km/h in 7.3 seconds; its maximum speed is 215 km/h. Despite these performance figures, this multi-talented newcomer consumes an average of only 5.9 litres of diesel per 100 kilometres, and achieves the world’s lowest CO2 emissions in the SUV segment, with 157 grams per kilometre.

In the hybrid drivetrain, a completely new four-cylinder CDI diesel unit with a displacement of 2.2 litres acts as the internal combustion engine. In terms of exhaust emissions technology, thanks to the latest BLUETEC technology with AdBlue injection, this diesel engine is already among the world’s very cleanest power units. The technical highlights of this extremely compact and refined CDI unit with a geared camshaft drive mounted on the flywheel side include fourth-generation common-rail direct injection with an injection pressure of 2000 bar, innovative piezoelectric injectors and 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 performs convincingly in two important respects: firstly it contributes decisively to fuel economy, and secondly it significantly enhances driving pleasure by virtue of the so-called 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.

With the VISION GLK BLUETEC HYBRID, a distinctive character is entering the SUV stage whose special appeal lies in a combination of the four-square 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. For the first time, this body design enables typical off-roader advantages to be transferred to the more road-oriented, compact SUV class. 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 even in dense city traffic. The appealing design concept is reinforced by the special "alubeam blue" paint finish, whose incomparable depth further underlines the sporty aspects of the bodyshell design. Specially produced 20-inch light-alloy wheels and muscular wheel arches enhance the powerful aura of the Vision GLK BLUETEC HYBRID even further.

The Vision GLK BLUETEC HYBRID now demonstrates how outstanding performance could be paired with minimal fuel consumption in the future. What is more, this combination need not be confined to the new GLK-Class, which will enter the market in autumn 2008.
