If you ask us the new BMW M5 is one of the few cars that needs no updates, but it seems the German tuner G-Power does not agree. They have started to update the new BMW M5 sports sedan and of course that they have started with a Stage I upgrade that will increase the power up to a total of 640 HP.

The package includes a G-Power Bi-Tronik III that will increase the power from the standard 560 HP to a total of 640 HP and 573 lbs-ft of torque. As a result the sprint from 0 to 60 mph will be made in 3,9 seconds and to 124 mph in 11,9 seconds.

Of course no changes have been made for the exterior, but the tuner opted to add a new set of 21" alloy wheels plus a new coil-over suspension, stainless steel sport rear muffler and a new Ceramic brake system completed by brake pads with a larger pad area, higher friction rate as well as metal-coated brake lines.[...]
