The XM isn t lacking in the power department, especially in Label guise. With 738 hp on tap, it s the most potent car BMW has ever made. However, that didn t stop dAHLer from tinkering with the twin-turbo 4.4-liter V8 hybrid setup to extract even more oomph. The Swiss tuner worked its magic to unlock a further 100 hp from the electrified setup, taking the combined output to an immense 838 hp.
The tuner doesn t say if it fiddled with the combustion engine and/or the electric motor but we do know torque is also up. The electrified S68 now makes a colossal 1,100 Nm (811 lb-ft), a full 100 Nm (74 lb-ft) more than the stock XM Label. Complimenting the additional muscle is a custom exhaust system delivering a meaner soundtrack. The driver can alter the noise on the go thanks to the controllable bi-flap system.
Performance figures have not been released by dAHLer but it s surely quicker than a standard XM Label given the power boost. BMW quotes a 0 to 62 mph (100 km/h) in as little as 3.8 seconds. Flat out, the luxury mastodont does 155 mph (250 km/h). With the optional M Driver s Package, the top speed limiter is loosened to 180 mph (290 km/h).
Beyond the engine and exhaust upgrades, this XM Label also has the tuner s 23-inch forged wheels. These stately lightweight alloys with a Y-spoke design come wrapped in 285/35 R23 front and 325/30 R23 rear tires. You can tell this is a hotter Label version by the red accents while the matte paint job comes from the Individual catalog.
The XM isn t a V8-only affair since BMW also sells a six-cylinder version in some regions of the world. However, we haven t seen any tuners work on the cheaper XM 50e so far. We’d argue the entry-level model is the one in need of more power since it has less than the X5 xDrive50e.
