The F90 BMW M5 is a pretty powerful machine in stock form but that hasn’t stopped tuners from extracting even more performance from the sports sedan. This one here is called the MH5 700 and it is the work of German company Manhart Performance.

Thanks to a new engine control unit, the 4.4 litre twin-turbo V8 now makes 723 PS and 870 Nm of torque, which is substantially more than the standard car’s 600 PS and 750 Nm. The company says it takes just 5.9 seconds to accelerate from 100 to 200 km/h, but didn’t reveal the 0-100 km/h time – the stock car does it in 3.4 seconds.

Aside from a monstrous amount of power, Manhart also offers a full stainless steel exhaust system to ensure cold starts are louder and the turbos are heard more clearly. The addition of KW coilover springs bring the M5 closer to the ground by 20 mm while 21-inch Concave One aluminium rims finished in satin black and gold accents help create a more attractive stance.

Other visual enhancements include a carbon-fibre package that includes a front spoiler with optional side blades, a new one-piece diffuser and boot lid lip spoiler. Even the exhaust tips can be swapped out for 102-mm carbon-fibre units. Inside, the changes are minimal with just the company’s logo on the steering wheel and unique floor mats.
