BMW tuner Manhart creates 743-hp M6 Coupe

There are BMW M6 drivers out there for whom the stock output of 560-hp and 500 lb-ft of torque just aren't enough. At least that's what German tuner Manhart is betting on in unveiling their MH6 700 version of the M6 hardtop. Manhart has been tuning BMWs and only BMWs for 20 years, and they've worked on everything from the E30 3-series to the latest offerings from the Bavarian automaker. On the spectrum of BMW tuners, their creations are more performance-oriented than those of other shops, and swapping in large engines into smaller BMW cars is something of a specialty of theirs.

Their latest effort uses the BMW M6 as a starting point, and while it doesn't quite look like a sleeper, the changes to the exterior aren't completely over the top. What matters though is what's under the hood, and the M6's 4.4-liter biturbo V8 has received the tuner's Stage 4 performance kit consisting of a remapped engine control unit, a carbon air intake system, sport catalytic converters, and a new exhaust system. The result is an eye-watering 743-hp and 703 lb-ft of torque -- that's a bump of 183hp and 203 lb-ft of torque over the stock powerplant. That's enough for a 0 to 62 mph sprint of just 3.8 seconds, though the 12.4 seconds required to get from 50 mph to 155 mph is perhaps a more telling figure. Manhart says the MH6 700 will do 199 mph, which is plenty as far as we (and probably everyone else) is concerned.

The MH6 700 can reach a top speed of 199 mph, according to the tuning house.

On the outside, the MH6 700 has received a new front spoiler made out of carbon fiber, a new hood with air inlets, a trunk lid spoiler, and a rear diffuser. By far the biggest visual difference are the new 21-inch Concave ONE alloy wheels wearing Michelin Pilot Super Sport tires, though the MH6 700 also benefits from a rebound-adjustable KW variation 3 coilover kit.

No info on price or availability on this side of the Atlantic just yet, though starting with a black M6 is perhaps not a bad idea in the case of the MH6 700, as the carbon fiber body parts won't clash with the rest of the car as much.

Your move, Alpina!
