Audi RS e-tron GT Range Test

Whilst the name might be a bit of a mouthful, this is a serious car!
e-tron meaning it's fully electric, GT being the body shape, and RS being the hardcore version of that... it's a near 600bhp electric monster!
Outrageous performance, outstanding comfort and refinement but can it deal with the electric cars nemesis?... Motorways!
Rich and I took it to London to find out.
