The latest generation of the BMW M3 sedan is practically unrivaled in its own segment of the market, and G-Power takes that lead further with its performance tuning solutions promising up to 720 PS.
Called the G3M Bi-Turbo, the power kit lets the 3.0-liter inline-six engine stay under the hood, but replaces the ECU code completely. Other than that, modifications are surprisingly few – a new exhaust system, a few durable components, and that’s it. Once complete, the upgrade takes the output up to 720 PS (710 hp / 530 kW) and 850 Nm (627 lb-ft) of torque.
The more wallet-minded customers may opt for Stage I and II upgrades implemented exclusively through the ECU swap and get 620 PS (612 hp / 456 kW) or 670 PS (661 hp / 493 kW).
Also available from G-Power are assorted body kit parts for the latest M3 and the company’s signature Hurricane RR and RS wheel sets (see the gallery).
