We’ve been having plenty of tuning programs for the BMW Z4 recently, includingtwo projects done by Japan’s 3D Design, including the ’Z4 for North America’.
Today, the BMW Z4 is once again front-and-center in the tuning world, only this time, the program comes courtesy of Kelleners Motorsport. Unlike the works made by 3D Design, which were largely based on aerodynamic improvements, Kelleners Motorsport offers the whole gamut of upgrades, including on the powertrain.
With a 3.0-liter twin-turbocharged inline six-cylinder engine already under the hood of the Z4, Kelleners Motorsport gave it a jolting boost, raising the sports car’s output from 335 horsepower and 332 lb/ft of torque all the way up to a mighty impressive 400 horsepower and 398 lb/ft of torque.
In addition to the engine improvements, Kelleners Motorsport also dressed up the Z4 with a set of 19" and 20" Hamburg or Berlin rims, as well as a lowered ride height by 20mm at the front and 10mm at the rear. Inside, there’s also a new three-spoke sport steering wheel, aluminum pedals, velour floor mats, and bespoke interior finishes in leather with wood trims that can be requested as a customer order.
