Audi e-tron

Audi e-tron

The Audi R4 is a small sports car expected to be built by Audi. The R4 will have an electric variant as well as a gas-powered version.

The electric version will be based on the e-Tron concept shown at the 2009 Frankfurt Auto Show.

It will have a lithium-ion battery pack and four electric motors, one at each wheel.

The new flagship will be powered by a development of the e-tron’s electric powertrain.

There’s a lithium-ion battery pack with four electric motors, two on each axle, giving it a fresh take on Audi’s quattro four-wheel-drive theme.

These give an output of around 300bhp, as well as an incredible 4,500Nm of torque, delivering instant acceleration with 0-60mph in 4.8 seconds.

Top speed is likely to jump from the concept’s 124mph to a more supercar-like 140mph – all with no tailpipe emissions
