The initial hype is over, we’ve driven the car and production of the BMW 1 M Coupé has ended. For fans of one of the best cars to have emerged in 2011, however, all that’s left is to do and talk about is unleashing ‘more’ from the already potent baby M. Many German tuners have already had a go, including: TechTec; Kelleners Sport; and Manhart Racing. Now German BMW tuning specialists G-Power have released their performance package, which boasts M3 beating credentials.
In standard form the BMW 1 M Coupé produces 250 kW and 450 Nm of torque from its 3.0-litre, twin-turbocharged, straight-six engine and is capable of a 0 – 100 km/h sprint of 4.9 seconds. G-Power are known to be fans of supercharging for naturally aspirated engines like that of the current BMW M3, however, extracting more from the turbocharged 1 M Coupé has clearly been no problem.
The G-Power 1 M Coupé has been given flow-optimised exhaust downpipes, to lower exhaust gas temperatures, as well as new ECU software and a larger capacity cooling system. Apart from the new exhaust headers, the entire system has been replaced by a titanium item, which is 20 kilograms lighter than standard and offers tailpipes in either titanium or carbon finish. The changes amount to a power increase of 74 kW and a 140 Nm increase in torque.
In performance terms, the 324 kW and 590 Nm strong G-Power 1 M rockets from 0 – 100 km/h in 4.5 seconds and has a top speed of 300 km/h. Placing these figures in perspective is the BMW M3 with a 0 – 100 km/h sprint of 4.8 seconds and an electronically limited top speed of 250 km/h.
With the added power and speed in mind, G-Power have also increased the size of the brake discs, from 360 mm in front to 396 mm units with 6-piston calipers, as well as added height-adjustable coil-over suspension with nine selectable settings. The standard 19-inch wheels have also been replaced in favour of 20-inch G-Power Silverstone alloys, fitted with Michelin tyres.
