Hitting the road: A 1600km drive through epic terrain takes prototypes from high in the Rocky Mountains to the Arizona desert.

Warley, Essex - Hitting the road: In the third of a series of videos from Ford that tells the story of how the new all-wheel drive Focus RS was developed, a 1600km drive through epic terrain takes prototypes from high in the Rocky Mountains to the Arizona desert. The new RS, due in South Africa during the first half of 2016, has a specially uprated version of Ford's new 2.3-litre EcoBoost engine that's rated at 258kW driving all four wheels, taking it from 0-100km/h in 4.7 seconds - and this is the story of 'how they did it'.
