Hamann Motorsport had their way with the BMW M4, and what they produced is something that sounds beautiful.
Hamann Motorsport added aerodynamic parts, a new exhaust system, suspension and engine tuning.
So what do all those upgrades do for performance? Instead of having 431 HP and 550 Nm or torque, the Stage 4 BMW M4 has 517 HP and 700 Nm of torque. That's a crazy amount of power for a car that weighs about 1.5 tons.
The rims are Anniversary EVO black line versions, and I think that they suit this M4 very nicely.
