Hybrid drive: from zero to 100 km/h in only 6.6 seconds
A powerful diesel/electric hybrid drive system is further proof of the innovation at the heart of the Vision Grand Sports Tourer concept. In models such as the Grand Sports Tourer, the electric motor is set to become an indispensable companion to the diesel engine, since it helps to further reduce fuel consumption and emissions without compromising on agility, comfort and driving enjoyment.
This powerful hybrid consists of the state-of-the-art V8 diesel engine with 184 kW/ 250 hp from the S-Class and an electric motor (50 kW). As a result, the vehicle has 234 kW of total power and 860 Nm of torque available — top performance levels for this drive technology, which guarantees dynamic driving enjoyment. The Vision Grand Sports Tourer, for example, has the acceleration of a sports car — it can sprint from zero to 100 km/h in just 6.6 seconds. The car’s top speed is electronically limited to 250 km/h.
The diesel hybrid system’s fuel consumption is equally exemplary, delivering 30 mpg according to the American measurement method. With future engine generations, the drive concept of the Vision Grand Sports Tourer will offer the potential for even more impressive fuel efficiency, at 33 mpg. In the European driving cycle, the Vision Grand Sports Tourer with a hybrid drive uses about 20 per cent less fuel than a comparable diesel model.
Electronically controlled distribution of the workload between the diesel engine and the electric motor enables the benefits of both drive concepts to be used to the full: the electric motor kicks in when starting off, parking, driving in stop-and-go traffic or crawling in heavy traffic when less power is required, thus ensuring zero-emission motoring. Only when more engine power is required does the eight-cylinder CDI powerplant spring into life to provide powerful acceleration. During braking, the electric motor acts as a generator and produces current for recharging the drive battery.
The Vision Grand Sports Tourer breaks new ground by featuring a hybrid drive system in conjunction with permanent all-wheel drive – a combination which offers further proof of the concept's immense potential.
Additional technical highlights of this Grand Sports Tourer concept include a set of 21-inch wheels as well as large, perforated brake discs, AIRMATIC air suspension and sophisticated axle assemblies, all of which are designed to ensure optimal long-distance comfort and an outstanding level of active safety.
