A BMW parts retailer in Germany has just completed a new E92 335i Coupe project car fitted with the M5’s V10 engine in replacement of the standard car’s twin-turbo six. The special one-off was commissioned by Bremgo, a specialist in sourcing BMW parts and tuning accessories, and the one-stop shop is now offering all the parts necessary for the conversion to anyone crazy enough to shoe-horn the 507hp 5.0L into the Coupe.

Completing the mechanical changes is the adoption of the M5’s SMG instead of the Coupe's six-speeder. In addition to the new drivetrain, Bremgo has also loaded up the test car with BMW tuner gear including a Hartge perforated leather steering wheel and AC Schnitzer five-spoke alloy wheels, plus the pumped guards and bonnet from the new M3 Coupe as well as its carbon-fiber roof.

Not surprisingly, the car has been debadged. The only question remaining is what to name it.

This isn’t the first radical conversion undertaken by Bremgo. Their previous works include an E46 M3 fitted with a 543hp version of the M5 V10, and we suspect the upgraded engine may be the same spec as the one fitted in this new E92 version.
