Audi e-tron

Four motors – two on each axle – take the Audi e-tron from 0 to 100km/h in 4.8 seconds. Collectively, the motors put out 313 horsepower but check out the torque figures – 4,500Nm! That looks like a seriously insane number but remember that the concept of gearing for an electric car is totally different (most only have one gear) so you don’t exactly have multipliers like the first few low gears on a regular stepped transmission.

The torque that each electric motor produces can vary as required to create a torque vectoring effect. Perhaps you can call this e-quattro or something, but Audi doesn’t have a name for it. The car’s water-cooled lithium ion battery pack will allow a maximum range of about 248km but don’t expect that kind of range if you’re really gunning it on the B-roads. The rated range is for the NECD driving cycle.

Yes, it’s an electric R8 and all, that is very interesting. But I feel the most interesting part about this e-tron concept is the car-to-x communications system. It’s basically a wireless communication system where the Audi and various other data feed providers (traffic lights, other cars, etc) around the car are able to help the car make intelligent decisions on various systems. For this to really work, such a system really needs a standardised protocol but it’s very very interesting to hear what can be achieved.

For example – a car has spun out on a slippery road in a blind curve. Other vehicles are approaching quickly. The stuck vehicle uses car-to-x to send out a warning signal reporting the precise location of the hazard (itself). A corresponding warning then appears on the navigation system display of the approaching cars.

Look after the jump for a full press release with full details on the e-tron as well as some very hi-res images which you can use as wallpapers etc.
