The BMW M340d has always been a bit of a weird car as a mild M sedan with a diesel powertrain that is easily outperformed by the petrol-powered M340i. German tuning company Manhart now has the solution to make an M340d just as potent as its petrol sibling.
Dubbed the MH3 400D, Manhart’s creation not only boosts the sedan’s performance but also adds some extra panache to its design. Modifications start under the hood where the tuner has installed its MHtronik powerbox to lift the car from its standard 340 hp and 700 Nm (516 lb-ft) to a more considerable 380 hp and 568 lb-ft (770 Nm). To put those figures into perspective, the M340i has 382 hp and 369 lb-ft (500 Nm).

Complementing the tweaked engine software is a new exhaust with four 90 mm tailpipes and adjustable valves.
Then we get to the design. Making the car stand out from any regular M340i are silver and red stripes running down the sides of the car and over the hood and roof. Manhart has also installed a carbon fiber lip spoiler from the M Performance range as well as a more aggressive diffuser. The car also now sits on H&R springs that have lowered the ride height by 40 mm (1.57 inches) on the front axle and 30 mm (1.18 inches) at the rear axle.
Of course, Manhart had to replace the wheels, with theirs having a matte black finish and measuring 20×9 at the front and 20×10.5 at the rear, while wrapped in 255/30 front and 275/30 rear tires. Rounding out Manhart’s upgrades are new carbon fiber shells for the M sports seats, carbon fiber shift paddle, and illuminated Manhart door sills.
