G-Power’s in-house developed Bi-Tronik 2 V2 remap is ready to lift BMW M4 performance to a healthy 560 HP and 720 Nm (531 lb-ft) of torque.
This way, the Bavarian Coupe is now able to hit 100 km/h (62 mph) from a standing start in just 3.8 seconds, which makes it 0.3 seconds quicker than the regular car and just as fast as the 2016 M4 GTS, with 500 PS of its own.
The Bi-Tronik 2 V2 ECU remap previously upped the M4’s output to 520 HP back in January and then 552 HP a couple of months ago, though neither peak power nor torque were ever this high, which is something that reflects even during high speed runs.
Theoretically, by removing the car’s Vmax limitation, the G-Power M4 could reach 330 km/h (205 mph), which is Huracan territory.
One would imagine that potential customers would seriously consider doing so, because what good is tuning your car if you’ll still fall short when it comes to pushing its boundaries. If you’re still not convinced that this is a seriously monstrous machine in a straight line, make sure to see a similar one in action taking on 700+ HP opponents.
Aside from the software upgrades, G-Power downpipes were added to significantly reduce the exhaust back pressure, along with an in-house titanium exhaust system, saving 7.1 kg (15.6 lbs). Those 21″ Hurricane RR forged alloys are pretty sweet too.
So yes, while this may not sound like a gigantic upgrade on paper, it’s more than obvious that the BMW M4 doesn’t require too much power in order to keep up or even beat much more “muscular” opponents when it comes to good old-fashioned straight line action.
