2013 BMW X6 "SP6 X" By Sportec

Sure, at one point in the past diesels were loud, rough and loaded with nothing but torque, but times are changing. We have a sneaking suspicion that this tune may change your perception of a diesel engine.

The package mainly focuses on the performance of the X6. In this example, the car is powered by a 3.0-liter twin-turbo six-cylinder diesel engine that, thanks to Sportec, now produces 370 horsepower and 750 Nm (553 pound-feet) of torque, a nice bump from the stock 306 horsepower and 600 Nm (442 pound-feet) of torque.

This bump in output helps shave 1.1 seconds from its stock 6.5-second 0-to-100 km/h sprint, which in real-time, 1.1 seconds seems like nothing, but in a 0-to-100 launch, that’s a lifetime. To add to the beefy upgrade, Sportec has also upped the top speed from 210 km/h to 263 km/h, making this Bimmer a touch more exciting.

Finally, the exterior features sporty exhaust tail pipes that breathe out more spent-diesel-fuel fumes and custom 19-inch OZ wheels to reduce the X6’s weight and add a little extra sport to its look.
