The upgrade begins with G-Power taking the 4.0-litre V8 taken apart before reconstructing it with a modified forged crankshaft, reinforced connecting rods and forged Mahle pistons, taking displacement up from 4.0 to 4.6-litres. The company’s SK III ASA T1-724 supercharger kit was then added, along with a titanium exhaust system weighing 26 kg less than its factory counterpart, larger water and oil coolers, and a meaty intercooler.
Those changes result in a monumental 537 kW (720 hp) and 700 Nm of torque; enough for 100 km/h to appear in 3.7 seconds, 200 km/h in 9.5s and a top speed in excess of 340 km/h (211 mph).
Other upgrades include a Clubsport adjustable coilover kit and G-Power’s 20-inch Silverstone Diamond alloy wheels wrapped in Michelin Pilot Super Sport rubber, while the standard brakes have made way for carbon ceramic items measuring 396 mm up front and 300 mm at the rear, gripped by six and four-piston calipers respectively.
Visually, the M3 Coupe wears a lower front spoiler, and a replacement bonnet and boot lid constructed from carbon fibre.
