The Manhart MH3 650 Touring comes with a front splitter, bumper-mounted aero flicks, side skirt extensions, rear spoiler and new diffuser. You also get 21-inch Manhart Concave One alloy wheels that come in silk matte black as standard but you can choose any color you like.
With the help of the MHtronic auxiliary control unit and no change in the hardware, the twin-turbo 3.0-liter inline-six engine produces 650 hp (478 kW) and 800 Nm (590 lb-ft) of torque. Thus the MH3 650 Touring is more powerful than the MH3 600 sedan.

The model also gets a new exhaust system with valve control, optional racing downpipes (with or without catalytic converters), or OPF-delete pipes. Although Manhart didn't discuss it, the MH3 650 Touring can always be upgraded with H&R lowering springs or more robust KW coilovers, just like the regular MH3.
If you are interested in having your M3 Touring turned into an MH3 650, Manhart is the tuner for you. They have a website where you can contact them for pricing and availability.
