The kidney grille isn't decorative — it feeds air to intercoolers, oil coolers, and radiators under sustained track load. Airflow efficiency outweighs nostalgia.
3.0L Twin-Turbo I6
Closed-deck block. Forged crankshaft. Twin mono-scroll turbos. Reinforced for sustained track abuse.
Multi-Radiator Loop
Central + side radiators. Auxiliary oil cooler. Built for track thermals.
POWER
HP — COMPETITION
TORQUE
NM
Real downforce. Manages airflow under the car. Reduces front-end lift at speed.
BALANCE
Near-perfect distribution. The car rotates mid-corner without resistance.
ROOF
Carbon-fiber reinforced polymer. Reduced mass above CG improves roll inertia.
MASS SAVED
Every gram above the CG compounds into dynamic gains.
TRACK WIDTH
vs standard 4 Series. Less understeer.
Low polar moment of inertia means responsiveness that defies the car's size. A lower CG and wider track means this chassis rotates better than its footprint suggests.
ACCELERATION
0—60 MPH
Flared Fenders
Staggered 275/285 setup. Functional grip engineering, not cosmetic widebody.
Adaptive M Dampers
Track vs comfort = real mechanical differences in damping force.
M xDRIVE
LB-FT TORQUE
Rear-biased torque split with dedicated 2WD mode. Planted at entry, loose at exit.
Quad System
True dual-branch architecture — not a single pipe split into four tips. Electronically controlled flaps.
Active M LSD
Real-time torque distribution across the rear axle. Essential for controlled oversteer on exit.
Rear Diffuser
Active air extraction from underbody. Stabilizes the rear at speed. Rear aero matters more than most think.
Carbon Ceramic
Reduced unsprung mass. Extreme heat resistance. Power means nothing without stopping.
