Tunisia is a small country, situated in the northern Africa. It’s a link between the Sahara desert and the Mediterranean Sea. It only has 10 million citizens, so it’s not a big thing to own the most powerful BMW in Tunisia. I mean – how many BMWs can be in such a small country?

Well, maybe not as many as in Germany, but this isn’t the point. The point is that, no matter what’s the country, this F10 BMW M5, upgraded by Manhart, could be amongst the first 10 most powerful. All the more in Tunisia.

That’s because its V8 powertrain, displacing 4.4 liters, has been upgraded in an strong manner. It forgot about the old 560 hp and 680 Nm of torque, saying hello to new, mind blowing numbers: 740 hp and 860 Nm!

Something must be wrong…where this extra 180 hp and 180 Nm from? According to the german tuner, the MH5 S Biturbo (that’s its new official name) pulls the extra output, mainly from the Manhart improved software. Then, a carbon fiber intake system restricts less the fresh air, while adding a more personalized sound note. Speaking of the sound, a completely new stainless steel exhaust system, including sport-kats, 4 x 90 mm end pipes and valve control, improves both, the sound and the power.

It’s also a new, fully adjustable suspension kit, made by KW and carefully tuned by Manhart, to best fit the engine’s performance. Sending this tremendous power to the ground takes wide, grippy tires. In front – a 265/30 ZR21 pair of wheels keep the car on track, while in the rear, the wider 305/25 ZR21 stick to the asphalt in the fast corners.

Some body panels, like the bonnet, the trunk lid spoiler, the rear diffuser, the front spoiler and the mirror caps were replaced by new, carbon-fiber made ones. The original color proposed by Manhart was Wrapping Grey. However, the owner didn’t consider it as appropriate, replacing it with a new, gutsy shade of blue, combined with black body elements. Just look at the pictures and decide for yourselves!
