Dahler tuning firm from Switzerland joins the rest of the gang that love playing around BMW models and creates a special program on the second-generation X4 M40i and M40d. You can find the latter one detailed in the media gallery below.
Dahler is commonly known for its programs on plenty of models from German manufacturers like Audi, Mercedes-Benz or Porsche, yet it recently turned its attention towards BMW customizations. Well, not quite recently…as for the past five years or so.
Visually, the striking thing that I have first noticed was the new set of wheels. It involves much larger wheels, sized 9 x 21-inch and 10.5 x 21-inch front and rear, respectively. The wheels go swell with the bespoke sport suspension system with shock absorbers, which lowers the SUVs ride height and provide greater stance and increased grip. The shock absorbers also make it “make it sporty but never hard.”
Announcing a power increase and a wilder engine roar is the in-house built Dahler stainless steel exhaust system with no less than four tailpipes. It also enhances the SUV`s impressive stance and aggressive look.
Performance wise, the stock BMW X4 M40i is powered by a 3.0-liter six-cylinder engine, developing 350 PS and 500 Nm of torque. However, with the tuner`s ECU remapping and new turbos, the M40i is now capable to churn out 420 PS and 630 Nm of torque, resulting an increase of 60 PS and 130 Nm of torque.
There is also good news for those owning the top of the line X4 M40d, the tuner also offering a tuning offer. The same stock engine puts it to 326 PS and 680 Nm of torque. Now, with the new power upgrade, the topper got no less than 380 PS and 780 Nm of torque, which is quite impressive. We would have loved hearing about the performance figures it the straight line, but for the moment, the tuner chose not to reveal that for the moment. Hopefully we get updates pretty soon!
Until then, you can admire the gorgeous BMW X4 in its top of the line M40d form in the media gallery below! Enjoy and don’t forget to tell us if you like the new tuning tweaks!
