Some owners of the E60/E61 BMW M5 aren’t willing to swap their rides for the latest version – and for a good reason, as they pack a naturally aspirated 5.0-liter V10 engine. The stock output is 507 PS and 520 Nm of torque, or less than 100 PS shy off the new model, which has two less cylinders. Not bad for a car that dates back to the previous decade.

But what if one needs more power from their trusty M5? Well, then they’ll have to turn to a tuner. In the case of G-Power’s supercharger, the output grows to a staggering 700 PS and 680 Nm of torque.


The upgrade fits both the E60 and E61 saloon and Touring (estate) versions of the M5, as well as the second-gen M6. The latter was around from 2006 to 2010 and uses the same 5.0-liter V10 as the M5. G-Power doesn’t say how fast their tuned E61 BMW M5 is, but the upgrade costs a steep € 16,838.50 (US$ 20,900), and that’s without installation. This can be joined by other aftermarket parts, such as a new exhaust manifold and sport catalysts.

Browsing through their offerings reveals yet another compressor system for the BMW M5/M6, which raises output to 1,001 PS and costs € 69,500. That’s about € 10,000 more than a new M2 Coupe in Germany, but hey, it boasts the exact same output as the first Bugatti Veyron!
