Manhart has been offering tuned F90 M5s since 2018 in the form of MH5 700, but taking inspiration from the facelifted 2021 M5 and the 2022 M5 CS, they announced the new and even more powerful MH5 800.
The twin-turbo 4.4-liter V8 is here tuned to produce 804 hp (599 kW / 815 PS) and 1,050 Nm (774 lb-ft) of torque. This makes it 187 hp more powerful than the stock M5 Competition and 177 hp over the most powerful M5 CS coming from the factory.
This was achieved thanks to Manhart’s turbo performance kit, intercooler, carbon intake, exhaust, and ECU remapping, while the 8-speed automatic gearbox was also upgraded to withstand the increased torque (+300 Nm / 221 lb-ft).

The company didn’t provide any performance figures but we are sure that the MH5 800 will be faster than the stock M5 Competition, which accelerates from 0-100 km/h (0-62 mph) in 3.3 seconds and has a top speed of 305 km/h (190 mph).

The new exhaust by Manhart includes “Race” downpipes without catalytic converters, stainless steel OPF-delete replacement pipes, and stainless steel rear silencer with valve control. The four tailpipes are optionally offered with carbon-coating or ceramic coating. In case you wondered, the downpipes don’t have TÜV approval so they can only be used in export markets outside Germany.
Besides the engine and exhaust, Manhart tweaked the suspension with adjustable H&R lowering springs (-30 mm) offering improved handling.
While the official photos published by Manhart are showing a pre-facelift BMW F90 M5, the upgrades are also available for the newer model. Visual modifications are discreet, with the most obvious one being the 21-inch Manhart Concave One alloy wheels finished in matt black, shod in mixed performance tires (265/30ZR21 at the front and 305/25ZR21 at the rear).
There is also a carbon-fiber aero kit (spoiler, side skirts, mirror caps, diffuser, rear spoiler lip) and an optional carbon hood with GTR inlets (not pictured). For this specific example, Manhart chose a mat red metallic wrap sending pink vibes, combined with a black stripe and black side graphics.
Inside there is a sky roof headliner with LEDs resembling the Rolls-Royce treatment, and lots of carbon fiber trim on the dashboard, steering wheel, and shift paddles.
As we can see from the official brochure, the total cost of the upgrades is €46,045 ($54,585) without VAT, over the cost of the donor car. This includes €15,795 ($18,728) for the engine upgrades, €10,485 ($12,428) for the exhaust, €3,324 ($3,944) for the wheels and suspension plus €15,472 ($18,344) for the complete set of visual modifications.
