Yet another modified BMW X5 M tempts us with its massive power gains.
The aftermarket performance offerings for BMW’s finest M-branded SUVs are increasing by the day, and the latest tuning package for the V8-behemoths comes from Swiss company Daehler.
What sets this firm apart from the countless other tuners in the industry? The answer is, moderation. Daehler isn’t the kind of tuner which squeezes all the power in the universe out of an engine, but instead settles for a more sensible approach.
For instance, Daehler offers a carefully tuned performance upgrade for the relatively new BMW X5 M model, increasing the automobile’s power output in two stages. The first stage boosts the engine’s standard 567 hp and 750 Nm (553 lb-ft) of torque output figure all the way to 664 PS (654 hp) and 820 Nm (605 lb-ft) of torque, while the second stage increases it a tad further, to 680 PS (670 hp) and 860 Nm (634 lb-ft) of torque.
That’s enough to make the 2,403 kg (5,299 lb-ft) SUV accelerate from 0 to 100 km/h (62 mph) in 3.8 seconds and onwards to a (tuner-limited) top speed of 305 km/h (190 mph). That’s without adding other goodies, such as performance catalysts, stainless steel exhaust system, adjustable suspension and bigger wheels (although, admittedly, the last two won’t boost the vehicle’s power).
In addition to these mods, Daehler also tweaked the engine’s overall characteristics, revising the RPM limitation to make it a little friskier and the gas pedal’s response time, thus reducing turbo-lag. Last, but certainly not least, the package, which is also available for the X6 M, complies with the current CO2 emissions standards.
