BMW X6 SP6 X by Sportec

Swiss tuner Sportec has developed an aftermarket program for the 2013 BMW X6.

They focused on the inline-six 3.0-liter diesel engine which in its standard configuration puts out 300 hp (223 kW) and 300 lb-ft (406 Nm) of torque. By remapping the ECU and updating the air intake they were able to lift output to 370 hp (276 kW) and 553 lb-ft (749 Nm) of torque.

Thanks to this significant power boost, the X6 is able to perform the 0-62 mph (0-100 km/h) sprint in 5.4 seconds, making it 1.1 seconds quicker than the stock X6 diesel. Top speed is also up from 130 mph (209 km/h) to 164 mph (264 km/h).

Changing gears is now done a lot faster thanks to the revised ratios of the eight-speed Steptronic automatic transmission. Sportec has installed a set of 20-inch OZ lightweight alloy wheels which have lowered the car's curb weight by 40 kg (88 lbs). Lastly, the customized sports exhaust system features carbon fiber tailpipes.
