When the BMW X6 was launched in 2008, it was the only one of its kind on the road. The concept of an SUV coupe was unknown back then and the X6 never had any rival all these years until recently.  The 3.0 litre twin turbo six-cylinder diesel motor that powers the X6 makes 313 horsepower at 4400 rpm with a whopping 630 Nm of torque that comes from 1500 rpm. It goes from 0 to 100 in a claimed 5.8 seconds.   Underway, the X6 is a confident, brawny machine, transferring this sensation to the driver. The X6 is an extremely versatile car and can cover big distances with ease, making it ideal for families who do lots of travelling.   Dynamically, the X6 is outstanding — arguably one of the best-handling and most involving SUVs you'll find today.
