I really mean it, what looks like and actually used to be a BMW M3, in E93 convertible form, is no longer that. This is something simply manic.
It’s a Manhart MH3 V8 R Biturbo and every bit of the name is justified. The heavy and industrial kind of pronunciation is necessary in order to warn people of what’s going on.
The M3’s standard 4.0 liter naturally aspirated V8 engine is a pretty cool proposition and will outperform justa bout any usual request it is faced with.
When you mess around with high end German tuners showing off for the current Essen Motor Show it’s not even good enough for a base setup.
The guys at Manhart merely chucked it all out and replaced it with chunkier, more modern BMW sourced V8, namely the 4.4 liter twin-turbocharged unit out of the X6 M.
It’s something that usually provides more than sufficient tork to lug around something weighing in at nearly twice the M3.
Even so, it felt like it wasn’t enough so the ECU and turbos receive a bit of a going over in order to produce a total of 655 horsepower and 719 lb-ft of torque.
The gearbox and rear diff receive some strengthening in order to handle all that grunt. The ideal is unusual but the removal of the max speed makes it all worth it.
The Manhart MH3 V8 R Biturbo can hit a top speed of 199 mph. It almost certainly can accelerate some way or another but that colossal torque is a problem for launches.
