BMW M3 and M4 by G-Power
Nowadays, rounding up 1200 metric
horsepower is relatively easy. You could do it with one supercar, or with a
pair of tuned BMWs; just like G-Power did.
When every other tuner throws
performance figures like it’s nothing, the 431 ps 3.0-litre
straight-six Bavarian twins – the M3 and the M4 – seem relatively decent. Don’t
get us wrong, 431 ps is a lot, beyond the average driver’s requirements, but the
figure fades away in comparison to G-Power’s latest aftermarket exercise.
Through the use of its Bi-Tronik 2 V3
module with bespoke control parameters the German tuner squeezed 600 ps and 740 Nm of torque from each vehicle. Since G-Power’s 600 ps goal was well beyond the capabilities of the vehicles' stock
components, the turbochargers were replaced with larger, lighter units, which
reduce inertia and improve throttle response. The new units also reduce exhaust
gas, allowing higher boost pressure and, subsequently, more grunt.
Contributing to the final power output
are larger exhaust downpipes (without cats) and a lightweight titanium exhaust
system with carbon-fiber encased tailpipes which reduce back-pressure.
All these mods translate into a 0 to 100
km/h acceleration time of 3.7 seconds (0.5 seconds faster than stock),
and a limited top speed of just over 320 km/h. Moreover, in order to
cope with the extra oomph, the vehicles received a fully adjustable GM4-RS
coil-over suspension, aerodynamic carbon fiber components (designed to reduce
lift), and a set of 21-inch G-Power Hurricane RR lightweight, forged wheels.
