A more sensible alternative to the full-blown X5 M, the BMW X5 M50i is still very powerful thanks to its twin-turbo 4.4-liter V8 that’s rated at 530 PS (523 HP / 390 kW) and 750 Nm (553 lb-ft) of torque.
Even so, Dahler has launched an upgrade package for it. While the tuner did not say how they achieved the 630 PS (621 HP / 463 kW) and 840 Nm (620 lb-ft) output, their kit apparently meets the latest European emission standard and comes with an increased top speed, to 270 km/h (168 mph).

Built internally by the tuner, a stainless steel exhaust system is also available for the X5 M50i. It sports four ceramic coated tailpipes measuring 101 mm (4 in) in diameter, and partially contributes to the risen output and torque. Additionally, customers can order the exhaust valve controller that gives the driver total control over the noise levels, regardless of the selected driving mode, so that they can choose how loud their want their ride to be.
A set of sport springs that lower the ride height of the X5 and the new 11×23-inch forged wheels, available in different colors and wrapped in 305/30 tires, round out the modifications. Dahler has other upgrades for the X5 M50i in development, such as a stage 2 kit, which will further increase the power of the V8, and a performance coilover suspension with adjustable height and stiffness tailored specifically for the German SUV.
