We're not going to say too much about this one, except that G-Power is one of the more prolific BMW tuners around the globe. We'll let G-Power tell you in their own words what they're working on.

Dear colleagues,

It is here: The all new BMW M5 (F10) has already arrived at G-POWER!

Currently the engineers at G-POWER are busy developing this car and the first results from the engine department are very promising.

The goal for the first stage of output enhancement for the G-POWER M5 (F 10) is expected to set 620 hp / 456 kW.

As soon as the development work has come to an end, the fans of G-POWER can look forward to one of the most spectacular BMW M5s for the season 2012. And that is just the beginning...

As a reminder, power in the standard BMW M5 F10 comes from a twin-turbo 4.4-liter V8, which produces 560 PS (412 kW / 552 hp) and 680 Nm (502 lb-ft) of torque. It is paired to a seven-speed M Double Clutch Transmission that enables the car to accelerate from 0-100 km/h (62 mph) in 4.4 seconds, 0-200 km/h (124 mph) in 13.0 seconds and hit a top speed of 250 km/h (155 mph) - or 305 km/h (190 mph) with M Driver's Package.

One thing to note is that the exhaust pipe tips in the image above look slightly larger than the standard M5 tips.
