The kerb weight for the 840d xDrive is 1,890 kg (4,167 lb) coupe version and 2,030 kg (4,475 lb) for the convertible version. mitsubish wallpapers, lamborghini, mazda wallpapers, BMW 8 Series G15 wallpapers, aston martin wallpapers
(Porsche 911)One of Porsche’s primary objectives with the new model was to improve fuel economy as well as increase performance. In order to meet these objectives, Porsche introduced a number of new technologies in the 911. One of the most controversial of these is the introduction of electromechanical power steering instead of the previous hydraulic steering. This steering helps reduce fuel consumption, but some enthusiasts feel that the precise steering feedback for which the 911 is famous is reduced with the new system. The cars also feature an engine stop/start system which turns the engine off at red lights, as well as a coasting system which allows the engine to idle while maintaining speed on downhill gradients on highways. This allows for up to 16% reduction in fuel consumption and emissions over the outgoing models.
The new cars also have a number of technologies aimed at improving handling. The cars include a torque vectoring system (standard on the Carrera S and optional on the Carrera) which brakes the inner wheel of the car when going into turns. This helps the car to turn in quicker and with more precision. The cars also feature hydraulic engine mounts (which help reduce the inertia of the engine when going into turns) as part of the optional sports chrono package. Active suspension management is standard on the Carrera S and optional on the Carrera. This helps improve ride quality on straights, while stiffening the suspension during aggressive driving. The new 991 is also equipped with a new feature called Porsche Dynamic Chassis Control (PDCC). Porsche claims that this new feature alone has shaved 4 seconds off the standard car’s lap time around the N?rburgring. PDCC helps the car corner flat and is said to improve high-speed directional stability and outright lateral body control, but according to several reviews, the car is more prone to understeer when equipped with this new technology.
