The vehicle is based on the M760Li version equipped with a twelve-cylinder engine, a power unit no longer offered in current BMW models. The project demonstrates the potential for upgrading a full-size luxury sedan and shows how it is possible to combine a refined interior with performance approaching that of sports cars.
Rare engine at the heart of the project
For decades, large German luxury sedans were traditionally fitted with powerful multi-liter engines. However, tightening emissions regulations and shifts in manufacturer strategies have gradually led to the disappearance of such powertrains. As a result, vehicles equipped with V12 engines are becoming increasingly rare.
The Manhart project is based on a BMW M760Li from the G11 generation. This variant was powered by a 6.6-liter twin-turbocharged V12 gasoline engine. In factory form, it produced 610 horsepower and 800 Nm of torque.
Powertrain enhancements
Manhart engineers focused primarily on upgrading the engine. The project features modified turbochargers and the installation of the proprietary MHtronik Powerbox control unit. A sports exhaust system was also fitted.
Following the upgrades, the engine output has increased significantly:
- power raised to 711 horsepower
- torque increased to 1050 Nm
The standard M760Li accelerates to 100 km/h in approximately 3.7 seconds. Top speed is electronically limited to 305 km/h with the optional M Driver’s Package. Exact performance figures for the modified version have not been disclosed, but the substantial power increase suggests even stronger dynamic capabilities.
Exterior modifications
The exterior changes are deliberately restrained and preserve the sedan’s overall character. The vehicle received a carbon-fiber front splitter, new mirror housings, and a subtle trunk lid spoiler.
It is also fitted with 21-inch forged Concave One wheels. The brake system remains stock, but its dimensions are sufficient to accommodate wheels starting from 20 inches in diameter.
The suspension has been upgraded and mildly lowered, improving high-speed stability.
Interior and equipment
The cabin retains the original BMW 7 Series architecture. The interior is upholstered in natural leather in beige and brown tones, emphasizing the vehicle’s executive character.
Manhart offers extensive customization options. Customers can order the full modification package or select individual elements — such as exterior changes or engine upgrades.
Market positioning of the project
The cost of the complete upgrade package has not been disclosed. The donor vehicle itself is only available on the used market, as new BMW models are no longer equipped with V12 engines.
The MH7 700 project illustrates that previous generations of flagship sedans can remain relevant thanks to targeted technical enhancements. Such vehicles continue to offer a combination of powerful engines, high levels of comfort, and a classic interior layout.
Conclusion
The Manhart MH7 700 is a thorough modernization of the previous-generation BMW 7 Series luxury sedan. The project combines a rare twelve-cylinder engine, substantially increased output, and discreet design modifications. The result is a vehicle that remains a refined luxury sedan while gaining performance comparable to powerful sports models.
