Acceleration & Sound Drag & Track by turboandstance - December 1, 2019 It's time for something a little different! We've managed to get ahold of a souped-up Mountune Ford Focus RS! Normally, this hot hatch, with its 350hp output, would be obliterated by the Mercedes-AMG G63 and the E63 S estate, both of which have immense, 4.0-litre, twin-turbo V8s and around 600hp!
