Thanks to G-Power, the 2015 BMW M6 F12 Convertible is now capable of producing 740 hp (544 kW) and 975 Nm. The ECU upgrade was achieved with the remapping Bi-Tronik. The complete Titanium exhaust system, which features Titanium 4-tip sport silencer and Titanium link pipes with resonators, was also added. The BMW now has a throaty sound and also saves approximately 12 kg compared to the factory exhaust system. This system is also available with four Titanium or Carbon Tailpipes with a diameter of 100 mm each.
G-POWER also gave the M6 a new set of 21-inch HURRICANE RR cast alloy wheels shod with 255/30ZR21 and 295/25ZR21 Michelin tires.
These wheels are usually obtainable in Jet Black, Gun Metallic Gray and Stardust Silver, however will also be painted in a particular color at additional value upon buyer request.
