New wheels and a revamped interior also forms part of the upgrade package.
BMW tuning specialist G-Power has unveiled a host of upgrades including a massive power boost for the M6 Gran Coupe. Dubbed the Bi-Tronik 5 package, the performance upgrade, made up of a remapped ECU and titanium quad exhaust, sees output upped by 180 hp and 217 lb-ft of torque to a monstrous 740 hp and 719 lb-ft. The exhaust also provides a “deep, throaty sound” while reducing weight by 12 kg. Top speed has increased to 186 mph as a result, with 0-124 mph happening in just 10.5 seconds.
The most notable style upgrade is the addition of the tuner’s 21-inch Hurricane RR forged alloys, housing G-Power’s own high-performance carbon braking system. The tuner also developed an adjustable coilover suspension with nine selectable settings. Inside, the cabin now features a sports steering wheel, leather, Alcantara and carbon-fiber trim, iPads built into the rear of the front headrests, and a new multimedia entertainment system. Available individually, if you want the complete set of upgrades it will cost you over 41,000 Euros.
