High tech in compact form
The drive unit for the metroproject quattro showcases a fully independent, innovative hybrid technology. At work under the bonnet is a 1.4.litre TFSI engine developing 110 kW (150 bhp), whose power is directed to the front wheels by means of the S-tronic Direct Shift Gearbox. A 30 kW (41 bhp) electric motor positioned on the rear axle is able to deliver up to an additional 200 Nm of torque when the vehicle is accelerating. When boosting, in other words driving the vehicle simultaneously by TFSI and electric motor to achieve a dynamic driving style, the study is transformed from a front-wheel-drive car to a quattro, and power is transferred to the road in the most effective way possible.
The electric motor is furthermore capable of powering the vehicle alone for zero-emission driving in residential areas, for instance. The capacity of the lithium-ion batteries gives the vehicle a range of up to 100 km in pure electric mode; the motor can be recharged from any power socket. The automatic start/stop facility, energy regeneration and phases of purely electrical operation reduce the fuel consumption and emissions of the Audi metroproject quattro by around 15 percent compared to when it is running exclusively on the combustion engine. Despite its sporty performance (0-100 km/h in 7.8 seconds, top speed of 201 km/h), the study uses just 4.9 litres of premium fuel for every 100 km, while CO2 emissions average a mere 112 g/km.
