Ford Focus RS500

Taking the already potent RS as a base, the RS500 features a revised engine that will really get fast Ford fans talking. The Volvo-sourced turbocharged 2.5-litre has been tweaked by UK-based tuner Mountune. The result is a power output boosted to 345bhp – a 15 per cent increase from standard. Plus, torque has risen from 440Nm to 460Nm, to give the engine yet more mid-range punch.

To squeeze out all the extra power, the RS500 is equipped with an enlarged intercooler, which feeds colder, denser air into the engine. A larger exhaust downpipe and new fuel pump have been fitted to keep up with the unit’s higher performance demands.

In addition, the engine management system has been recalibrated to optimise the delivery of power for maximum pace. As a result, the sprint from 0-62mph now takes only 5.6 seconds – three-tenths faster than the standard car – while top speed is up from 163mph to 165mph.

Other than the engine changes, there have been very few modifications to the car’s chassis. The RevoKnuckle front suspension system – which reduces torque steer – remains the same, as does the Quaife limited-slip differential. The brakes are also carried over, although the calipers are painted red to help set the RS500 apart from lesser models. Ford has retained the 19-inch 15-spoke alloy wheels, too, but given them a metallic black finish.
