German BMW tuner and serial engine-swapper Manhart has released details of a 712bhp version of the already potent BMW M5. Called the MH5 700, its modifications comprise both hardware and software changes, alongside a set of aesthetic upgrades that create an altogether more aggressive package.
Starting under the bonnet, the engine itself is the familiar twin-turbocharged 4.4-litre V8 unit, but in this instance Manhart replaces the standard M5’s ECU with its own, dubbed MHtronik. This lifts the M5’s power from 592bhp up to that headline-grabbing 712bhp figure. Torque also swells from 553lb ft to 642lb ft. Manhart hasn’t revealed many performance figures, only stating that the MH5 will go from 100kph to 200kph in just 5.9 seconds.
Also fitted is a new stainless steel exhaust system, simultaneously reducing back pressure and addressing the somewhat demure sound of the standard M5.
