Ford tuner BBR has announced a series of performance upgrades for the Focus RS that allows the mega hatch to produce 398bhp.
The upgrades, from the company that tuned the Cosworth RS500 engine for the BTCC in the 1980s, come in four different phases and range from remapping the ECU software to new performance parts for the engine. The modifications have taken 18 months to develop.

The £595 Phase One model includes an ECU remap, improving throttle response and making the turbo's delivery more linear. The remap boosts power to 337bhp over the standard car's 300bhp, while torque is up to 369lb ft from 325lb ft.
The Phase Two package replaces the standard intercooler with one of BBR's own design. A new air filter and inlet hose set are also added, in addition to the phase one upgrades, to boost power to 350bhp and torque to 378lb ft.

This Phase Four upgrade package costs £3895, plus a £595 fitting fee and also includes the previous three upgrade packages.
