With 560 HP, the new BMW M5 is nothing short of a hit among tuners from all over the world: some want to make it look even more aggressive and others want to improve upon the already impressive performance numbers. The latest tuning package comes from Manhart Racing, who hope to prove that, when combined with the appropriate updates, the BMW M5’s standard 560 HP is more of a joke than a serious power offering.
The BMW M5’s standard 4.4 liter V8-Biturbo engine has been given a series of modifications on its turbochargers, downpipes, and exhaust-gas system.
