Manhart’s “MH3 3.5 Turbo” started as a BMW E30 E3 with a 2.3 L S14 inline-four. They swapped the inline-four for a turbocharged 3.5 L M90 inline-six from an Alpina B7 S Turbo. The motor produces 405 hp and 650 Nm (479 lb-ft) of torque thanks to a modified K27 turbocharger and Manhart’s intercooler and exhaust. The drivetrain uses a five-speed manual transmission and Drexler locking differential. The coupe rides on H&R suspension and Brembo four-piston calipers with 330×32 mm drilled rotors in front and E30 M3 calipers with 282×12 mm rotors in rear. On the exterior Manhart installs a carbon fiber front lip, matte green vinyl wrap, and their Concave One wheels (19×8.5, 19×9.5).
