The G-Power tuning shop is perhaps the fewest amongst famous aftermarket companies to deliver a power boost for the BMW M3 and BMW M4. And since we are complaining about the lack of power boost but the multi-tuning programs carried out at the body style for both models, here we have the official power increase.
Both BMW M3 and BMW M4 have received some upgrades under the hood, the sports cars receiving a revamped Bi-Tronik 2 ECU, the titanium exhaust system with the 90-mm tailpipes, as well as the G-Power downpipes. Surely that all these came for the right price: 2,750 euros for the Bi-Tronika 2 V2 ECU, 1,610 euros for the G-Power downpipes and 5,1640 euros for the G-Power exhaust system.
But what about the figures? 560 horsepower and 720 Nm of torque, which is quite impressive as opposed to the stock 425 horsepower and 550 Nm of torque. And the sprint is also outstanding: just 3.8 seconds to take down the 0 to 100 km/h straight short run.
Add up the 21-inch HURRICANE RR forged wheels, for no less than 7,640 euros and you have a hell of a ride, especially since they are highly performance with the ultra-light aluminum structure, which provide more grip and stance on the roads or tracks.
