The X6 xDrive40i is powered by BMW’s 3.0-litre, in-line, six-cylinder turbocharged petrol unit. Delivering 340hp, it comes mated to an 8-speed torque-converter automatic and sends power to all four wheels via BMW’s electronically controlled xDrive all-wheel-drive system.  Despite its bulk, the X6 makes light work of traffic. The 40i engine is particularly smooth in operation. It responds positively when you tap the accelerator, and ZF’s 8-speed gearbox is both, silky smooth and super quick. Put your foot down and the BMW even accelerates in an impressive manner, winding up the powerband with all the energy of a naturally aspirated engine, and pulling it all the way to the redline feels a real treat.  BMW’s third-gen coupé- SUV has its own individual look, the cabin is superbly built and put together, it is well equipped and, for all its bulk, it even drives in an extremely sporty manner.
