    Powerful diesel sedan: M340d as MANHART MH3 400d with 380 hp

    We at MANHART Performance usually deal with the vehicle refinement of sports and top models with powerful petrol engines under the hood. But that doesn’t always have to be the case. Because of course there are also attractive diesel models that lend themselves to optimization – especially in the BMW range. For example, the diesel top model of the current 3 Series-generation G20: the M340d. We chose exactly this M Performance mid-class car in the facelift version that has been available for about a year as the basis for our latest project car: the MH3 400d.

    As is well known, the M340d is powered by a three-liter straight-six. Thanks to double turbocharging, this already generated a full 340 hp and a beefy torque of up to 700 Nm in the standard version. With the help of the tried-and-tested MHtronik powerbox, we still teased out a few additional horsepower. As usual, the number in the new vehicle name serves as a pointer in the direction of the result: To be precise, it is 380 hp, while the torque increases to 770 Nm.

    As usual, we also gave the Munich limousine an individualized look. The silver and red stripes of the MANHART decal set stretch across the black painted body. There are also several carbon add-on parts from the M Performance range: spoiler lips for the front and the trunk lid and a diffuser for the rear. A 4-pipe exhaust system including 90mm carbon tailpipes replaces the stock tailpipes for an even more dynamic look. The rounding off highlight is of course the eye-catching new wheelset: These are our in-house Concave One rims. They are characterized by five powerfully drawn double spokes and a matt black finish. The dimensions are 9×20 on the front and 10.5×20 on the rear axle. The associated tires measure 255/30ZR20 and 275/30ZR20. Last but not least, the lowering by means of H&R springs by 40 millimeters on the front axle and 30 millimeters on the rear axle guarantees that these combinations are perfectly equipped under the fenders.

    In the interior, we refined the factory M sports seats with a carbon cover for the upper area of their back shells. Additionally we installed carbon shift paddles and illuminated MANHART door sills.
