Boosts output to 375 hp.
BMW tuning specialist Manhart has introduced a performance upgrade package for the X4. Based on the BMW X4 xDrive35d, the aftermarket project is still in development, but will boost the 3.0-liter diesel to 375 hp and 546 lb-ft of torque. That will give the little crossover similar performance to the M50d X5. Manhart is also working on a sport lowered suspension and will offer a set of 21-inch Concave alloys in silver or black.
