BMW M3 And M4 by AC Schnitzer
AC Schnitzer’s latest tuning upgrade for
the BMW M3 and M4 isn’t that impressive but only if you think that 510 PS and 654 Nm of torque are not enough.
Thanks to their turbocharged, 3.0-litre
S55 inline-six, the Bavarian vehicles are a tuner’s dream, mainly because the
engine can be easily upgraded to produce impressive amounts of power.
The power bump came mainly from an ECU
upgrade, lifting the engine's output from the factory's 431 PS to 510
PS, and from 550 Nm to 645 Nm.
AC Schnitzer’s re-worked exhaust
with silencers, flap control and sound pipe might’ve helped a bit, by improving
the gas flow, but at the end of the day it all boils down to the revamped
engine control unit.
Both vehicles can be commissioned with
either AC Schnitzer’s suspension spring kit (which lowers the car by around 25
- 30 mm at the front and 10 - 15 mm at the rear) or the RS adjustable
suspension (slamming the car closer to the ground by 30 - 40 mm at the front
and around 30 mm at the rear). Both solutions improve cornering, offer “gentle”
understeer at the limit and a good-natured load change.
A meticulously crafted
aerodynamic package was implemented. Composed of a multistage body styling kit,
the final Stage 3 variant features super-lightweight carbon front spoiler
elements (which weigh only 400 grams), including a racing splitter, carbon
fiber side wings, rear and roof spoilers, and even carbon fiber mirror covers.
Inside, as the German tuner bedizened the vehicles with various enhancements,
ranging from the aluminum pedal set and foot rest, to the aluminum gear knob
with digital gear display and handbrake handle.
