BMW M4 Coupe by G-Power
G-Power is offering its Bi-Tronik 2 V3
electronic control unit remap that is specifically calibrated to each M4 Coupe engine to ensure optimum performance and is joined by a bespoke titanium
exhaust.
What this amounts to is 600 PS and 740 Nm of torque, 150 PS over the M4 Coupe fitted with the
factory Competition Package. The tuned M4 needs 3.7 seconds to cover the 0 to 100 km/h sprint, beating the GTS by a tenth of a second, while the
removal of the electronic limiter raises the top speed to more than 320 km/h.
Looking for extreme one, the tuner provides
two additional engine upgrades, which bring the output to either 520 PS and 700 Nm or 560 PS and 720 Nm of torque.
Making sure that the M4 can handle the extra power
is the GM4-RS coilover suspension, which is said to not only provide a lower
stance, but optimize tire grip too, while the Hurricane RR forged wheels,
9.0x21- and 10.5x210-inch, wrapped in 255/30 and 295/25 tires, respectively,
round off the list of modifications.
G-Power charges € 1,785 (US$ 1,895) for the
Bi-Tronik 2 engine upgrade, which is also available for the M4 Convertible and
M3 Sedan, instead of the usual € 2,100 (US$ 2,230), as part of the 'X-Mas' Edition.
