The new Roadster 3.7 is deceptively fast with a Ford Cyclone six cylinder engine. Power delivery is smooth and consistent all the way up to the maximum engine revolutions of 6850 per minute. The overall weight of only 950kg for this aluminium car spells a power to weight ratio of around300bhp per tonne. Power delivery is transmitted to the road through a limited slip differential with cone drive for good traction off the line. The 6 cylinder engine and 6 speed transmission provide an excellent combination of performance and economy. Carbon emissions are extremely low for a fast sports car.
