The BMW M8 Competition (here in convertible form) has been given a thorough performance enhancement by G-Power, together with a new set of wheels.

Using the Munich-based firm's twin-turbo 4,4-litre V8 as a base, the tuner has added its GP-820 performance software and upgraded the turbochargers with larger compressor wheels and CNC-milled housings. Custom downpipes (with the option of removing the catalytic converter) and a titanium exhaust system with carbon-tipped tailpipes enhance the engine’s already muscular note.

The result? Well, the standard peak outputs of 460 kW and 750 N.m of torque have been increaased to 603 kW and 1 000 N.m. If those figures look familiar, that's because G-Power has already applied this upgrade to the M5 (Hurricane RS, anyone?).

Those looking for a smaller (yet still significant) bump in power can select a package offering 529 kW and 850 N.m or a mid-tier option with 566 kW and 930 N.m. Visual enhancements are limited to a set of 21-inch Hurricane RR forged alloy wheels wrapped in 285/30ZR21 front and 295/30ZR21 rear Michelin tyres.
