87 mph, when the maximum speed of the electric motor would be reached at approx. Electric drive mode: all-electric driving from a standstill up to 81 mph, the combustion engine always remains switched off. Individual drive mode: individual customization of the drive, transmission, AMG DYNAMICS, chassis, steering and exhaust system.
An actuator in the exhaust system, as fitted to the first SQ5 TDI, gives the V6 a sonorous sound. This offers the advantage since exhaustgas cleaning responds more quickly. The exhaust manifold benefits from improved insulation; the exhaustgas reaches the optimum temperature more quickly after a cold start.

At 50 km/h (31 mph), in third or fourth gear, savings amount to nearly one liter per 100 km. Afterwards, the system closes the intake and exhaust valves of cylinders 2 and 3; engine ignition only occurs once per crankshaft revolution. Volkswagen utilizes information from the gas pedal sensor to detect the driver’s mode of driving.
The new hybrid-electric system also allows for a substantial increase in continuous maximum speed, which climbs from 86 mph to 115 mph. Linear Shift Control elevates the driving experience by mimicking the vehicle speed-linked rev feel associated with a conventional drivetrain shifting gears at wide open throttle.

This Golf concept, powered by another new 1.6-liter liter TDI (turbodiesel) consumes 3.2 l/100 km (73.5 mpg US), equivalent to 85 gCO 2 /km. This third generation Golf BlueMotion will be launched into the market in summer 2013.
To further optimize gas exchange, the valve control system has been given greater operating freedom. The Audi valvelift system, which adjusts the lift of the valves in two stages, is active on the exhaust side. This concept benefited from the integration of the exhaust manifold into the water-cooled cylinder head.
The vehicle can accelerate to 60 km/h (37 mph) in less than 6 seconds, and top speed is higher than 120 km/h (75 mph). Modern engine management with electronic throttle, inlet pipe injection and three-way catalyst ensure that the exhaustgas emission limits will be met.
