560hp BMW M3 and M4 by G-Power

With 425 hp on tap in standard guise, the BMW M3 and M4 duo certainly aren’t slouches. Nevertheless, German BMW tuning specialist G-Power has unveiled its host of performance modifications for the pair of sports cars.

For starters, G-Power has created its Bi-Tronik 2 V2 ECU remap for the M3/M4’s twin-turbocharged 3.0-litre six-cylinder engine. Elsewhere, custom downpipes have been installed as has an expensive titanium exhaust system with four 90 millimetre tailpipes. The results of these changes see power rise to 560 hp at 6500 rpm and 720 Nm of torque at 4500 rpm. As a result, the G-Power BMW M3 and M4 will sprint to 100 km/h in a mere 3.8 seconds as well as a top speed of 310 km/h.

Alongside the performance tweaks, G-Power has created a custom set of wheels for the cars. The 21-inch Hurricane RR forged wheels are wrapped in 245/30 and 295/25 rubber and feature a refined, twin-five spoke design.


G-POWER M3/M4: 560 hp and 720 Nm puts it at the top of the

supercar league!

The star billing in BMW’s current M portfolio, the F8X series M3/M4 now

receives a performance upgrade from G-POWER centred on their in-

house developed Bi-Tronik 2 V2.

Boosting output to 560 hp / 412 kW with 720 Nm of torque, this

conversion catapults the Bavarian super saloon/coupe to 100km/h

from a standing start in just 3.8 seconds.

In line with G-POWER’s seven high-speed world records, a customer

can also request the remap to include removal of the factory Vmax

limitation, raising top speed to a theoretical 330km/h. In reality, the

car will achieve around 310km/h.

Key Facts: G-POWER M3 / M4 (F8X)

• 560 hp / 412 kW at 6,500 rpm (+129 hp / 95 kW)

• 720 Nm at 4,500 rpm (+170 Nm)

• V-max: 310 km/h

• 0-100 km/h: 3.8 sec.

• G-POWER Bi-Tronik 2 V2 remap from 2,750 euro net

• G-POWER downpipes 1.610 euro net

• Vmax increase from 668 euro net

• G-POWER titanium exhaust system 5,164 euro net

• 21 “HURRICANE RR forged wheels 7,647 euro net

Unlike generic remaps, the G-POWER Bi-Tronik 2 V2 ECU remap is

customised for the original control unit in a customer’s vehicle, thus

achieving optimum all-round performance enhancement.

In industry terms, while this is the best way to implement such an

upgrade, it is also the hardest as it means having to crack the factory

128-bit encryption first.

However, thanks to over 30 years of engine development experience,

the G-POWER engineers were able to overcome this electronic firewall

and implement their remap.

Extensive test runs on the dyno and real world testing on the

autobahns and country roads proved the dramatically enhanced

performance and perfect drivability of the Bi-Tronik 2 V2 conversion.

Of equal importance for engine reliability and longevity, the factory

diagnostic and engine protection systems remain in place.


Complementary to the Bi-Tronik 2 V2 package installed G-POWER

downpipes significantly reduce the exhaust back pressure. Moreover G-

POWER equipped the M3 with an in-house titanium exhaust system

with four 90-millimeter tailpipes, optionally available in titanium or

carbon fibre finish. Saving 7.1 kg over standard, this sports exhaust

features a sound flap in the rear silencer with remote control


Reduced unsprung mass equates to improved handling, both of which

G-POWER achieves with its 21-inch HURRICANE RR forged alloy wheels

shod with 245/30ZR21 and 295/25ZR21 Michelin tyres.

Made from ultra-light aircraft-grade aluminium these wheels are

normally available in Jet Black, Gun Metal Grey and Stardust Silver,

but can also be painted in a special colour at extra cost upon customer
