Kidneys that breathe.
The tall vertical kidneys are there for a reason: they feed cooling air to the twin-turbo straight six, lap after lap.
Air has the final say.
An unofficial BMW M concept. Switch on the wind tunnel and watch the M4 meet the flow.
Start the tunnelAir arrives first.
Smoke shows the path every M4 has to master: over the bonnet, along the roof, off the tail. Clean air here means a car that stays calm at the limit.
Read the pressure.
A laser sheet sweeps nose to tail and paints the load on the body.
- High pressureAir pushes hardest on the nose and the base of the windscreen.
- Low pressureAir speeds up over the roof and around the front edges.
Aerodynamic details
Wider where it counts.
The M4 sits wider than the 4 Series it grew from. Flared arches cover the broader track and give it the stance you spot from across the street.
Built to hold the road.
A rear diffuser and quad exhausts close the shape. This M Performance build adds a carbon rear wing for extra downforce.
