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.

“PRESS RELEASE – BMW Models
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.
PRESS RELEASE – BMW Models
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
regulation.
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
request.”
