Some of the best tuners in the world are Germans or Japanese, right? Well the guys at Hartge got their hands on a BMW 135i and pushed it to the limits by developing an ECU upgrade for the 3.0-liter bitrubo engine, that is now releasing nothing less than 350 hp (44hp more) at 5660 rpm and 480 Nm (lb-ft 354) at 2950 rpm.

The new BMW 135i by Hartge is topping at 280 km/h (174 mph) and goes from 0 to 100 km/h (62 mph) in just 4.8 seconds, which is half a second faster than the 5.3s standard. Price for a fully equipped BMW 135i tuned by Hartge is going to cost in Germany € 48,162.14, excluding VAT. Worth it?
