The e-tron may sound like a 60s robot from a bad sci-fi film, but in actual fact it’s a hand-built electric concept car from Audi. Based on their R8 supercar, the Audi e-tron packs not one but four 230kW (313bhp) electric motors, one for each wheel, for a total of 3319lb/ft of torque, 0-60mph times of 4.8s and a (limited) top speed of 125mph, without killing any rhinos, pandas or polar bears in the process (unless they jump out into the road).
