You can't really tell, but it's faster too.
Tuning options for the BMW M4 are already turning out to be big business. But that comes as no surprise, the model name might be new, but the basic idea behind the car is quite old, and one which tuners have loved for some time. So the more attentive tuners brought out a range of products right away, and here we can see Hamann’s. In addition to the new body pieces you’ll see here, power is up to 517 horsepower.
That’s up from the stock 431 horsepower. Torque has increased too, up from 406 lb-ft to 516 lb-ft. Not bad at all.
