Audi Metroproject Quattro

The metroproject quattro is a supermini/sub-compact, and was shown to the publuc at the 2007 Tokyo Motor Show. Under the bonnet/hood is a 1.4 litre TSI petrol engine, producing 110 kilowatts (150 PS; 148 bhp). This will distribute its torque of 240 newton metres (177 lbf·ft) to the front roadwheels via an 'S tronic' Direct-Shift Gearbox. However, in the back of the car, beneath a perspex peephole, is a 30 kilowatts (41 PS; 40 bhp) electric motor which drives the rear axle, and can generate an additional 200 newton metres (148 lbf·ft) of torque, designed to create a zero emissions driving experience in residential or city areas, and increase torque while the 1.4 TSI engine is accelerating.

A lithium-ion battery pack supports a range of up to 100 kilometres (62 mi). In electric mode, the car has a top speed of more than 100 kilometres per hour (62 mph). When both the engine and electric motors are working in unison, the car is transformed into a genuine quattro, with a combined torque output of 440 newton metres (325 lbf·ft) being shared between all four roadwheels. Stop-start technology will be utilised, as will regenerative braking. As a result, Audi claim a 15% improvement in fuel efficiency when compared to exclusive use of the internal combustion engine.

The A1 started production in 2010 but without a hybrid. There are also no plans to add such later; instead Audi plan an all electric version.
