BMW Performance Differential
Power. It’s the elemental force generated by a car.
And how it is transmitted to the road makes all the difference.
When you choose a BMW Performance Differential, that power is not only increased,
but delivered smoothly and efficiently. This includes a 5% increase in axle ratio,
increasing the torque delivered to the ground for faster, more immediate acceleration—up to 60 mph,
approximately half a second faster than the standard 330i. The result is heightened responsiveness,
and a more exciting drive no matter where you are headed.
