BMW tuning specialist G-Power has updated its offering for the M5 performance sedan with this G5M Hurricane RR package, which includes a hefty power increase and some visual enhancements.
As standard, the twin-turbo 4,4-litre V8 pushes 441 kW (or 460 kW in the case of the M5 Competition) and 750 N.m of torque to all four wheels. G-Power, however, has increased these outputs to 662 kW and 1 050 N.m by fitting a set of forged pistons, modified connecting rods, uprated turbochargers (with CNC-milled housings) and a software upgrade. The company furthermore added a larger radiator and "reinforced drivetrain".
G-Power describes the rated 662 kW peak power figure as "conservative". Adding a more menacing soundtrack is a set of downpipes with a 200-cell sports catalytic converter and titanium exhaust system with four 110 mm tailpipes.
Visual updates come courtesy of a set of 21-inch Hurricane RR forged alloy wheels, a GP Venturi carbon-fibre bonnet and a set of lowering springs.
