Powerhouse

Back in the day, 900 horsepower was practically science fiction and reserved for supercars with price tags that could rival a house. But thanks to Manhart, that kind of power is now tucked under the hood of a BMW M4, making it a beast on the streets. Manhart, the German tuning powerhouse, has transformed this M4 into the MH4 900 by fitting it with jaw-dropping upgrades.
Performance
Let’s talk numbers. Manhart has managed to squeeze out a staggering 922 horsepower and 878 pound-feet of torque from the BMW M4’s 3.0-liter twin-turbocharged inline-six engine. This monster is only about 79 horsepower shy of the famed Bugatti Veyron. This remarkable feat was accomplished through a meticulous upgrade process. Larger turbos, a beefed-up intercooler, and forged pistons and rods were added. Plus, the ECU got a revamp for managing all that newfound muscle.
Transmission
The M4’s eight-speed automatic transmission received a similar treatment to handle this power uprising, ensuring smooth operation when this baby hits the ground running. Though acceleration times haven’t been officially disclosed, the standard M4 zips from 0 to 62 mph in a quick 3.2 seconds. So, it’s safe to assume the MH4 900 can likely dip into the 2-second range, given the power boost.
Exhaust
With great power comes a great sound. The MH4 900 features a stainless steel exhaust system with adjustable valves and high-performance downpipes. The 110 mm tailpipes, now sporting a sleek carbon fiber coating, hint at the car’s aggressive personality whether it’s at a standstill or in full flight.
Looks
The MH4 900 doesn’t just perform like a supercar; it looks the part too. New H&R lowering springs and a set of matte black wheels keep it firmly planted to the ground. Sporting 20×10.5-inch wheels upfront and 21×11.5-inch wheels in the rear, it grips the road with 285/30 front and 305/25 rear tires.
Design
Aesthetics are taken to the next level with carbon fiber accents aplenty. A fresh front splitter, aerodynamic canards, and eye-catching side skirts all lead to a larger rear lip spoiler and diffuser, enhancing both style and performance. Inside, the cabin incorporates carbon-backed bucket seats borrowed from the M4 CSL, further indulging its race-inspired ethos.
Driving Experience
Driving the MH4 900 is an experience that redefines driving excitement. With its power plant roaring, the rear-wheel thrust shoots the car forward in what feels like a sling-shot motion, akin to catching a rollercoaster’s first downward plunge. When matched against others in its performance bracket, this M4 doesn’t just compete—it dominates with roaring confidence and visceral feedback, making it far more than just a set of wheels with an exceptionally tuned engine.
From its muscular performance to its striking exterior, the Manhart MH4 900 has transformed into something truly exhilarating, catering not just to the adventurous driver but also to the automotive aficionado craving engineering excellence wrapped in a stylish racer’s suit.
