Ford Focus RS Delivers Supercar Performance

Hot Hatch / 12 Comments

It's such a shame the Focus RS is no longer on sale in the US.

It was a sad day when Ford discontinued the formidable Focus RS in America. It's a different story in Europe, however, as both the Focus RS and Fiesta RS are still on sale. Just to make us jealous, British tuner Mountune has modified the hot hatchback so that it now delivers supercar levels of performance.

With Mountune's m450 package, the stock turbocharger is replaced with a BorgWarner EFR-6758 unit featuring a low inertia gamma-ti turbine wheel and dual row ceramic ball bearings that increase Ford's 2.3-liter EcoBoost engine to 450 horsepower and 428 lb-ft of torque.

Also included in the m450 package is a ni-resist cast turbo adapter, v-band high flow sports cat and downpipe, turbocharger gasket set, 5-ply compressor outlet/ Inlet Silicone Elbow and a stainless-steel hose clamp set. This upgrade will set you back £2,950 ($3,578).

The m520 package, on the other hand, takes the RS to the next level, by upgrading the turbocharger to a BorgWarner EFR-7163 unit, as well as adding an uprated fuel pump ,camshafts and valve train. The ECU calibration has also been tweaked. As a result, the modified RS produces 520 horsepower and 516 lb-ft – that's 170 more horsepower and 166 more lb-ft than the standard Focus RS. This more expensive upgrade costs £5,974.99 ($7,246.65). Mountune hasn't said how this affects the performance, but the standard Focus RS will do 0-60 mph in 4.7-seconds and top out at 165 mph.

"We have worked hard to develop upgrades that build on the success of the m400X and m400R kits," explains Alec Pell-Johnson, Director of mountune Performance. "With the very latest BorgWarner turbocharger platform, both upgrades deliver exceptional levels of power and torque, turning the RS into something quite remarkable. After the positive initial feedback we received from the official unveiling of the kits at Ford Fair, we can't wait to start fitting them to our customers' cars."

While the Focus RS may no longer be available in the US, Ford is preparing to unleash the next-generation model in Europe, which is rumored to pack a mild-hybrid setup that will increase the power to 400 horsepower to create a true hot hatchback monster.
