Make no mistake, the 6 Series GT may offer sleeker looks than a 5 Series saloon or Touring, but you’ll pay more for it. However, compared like for like with the Audi A7 or Mercedes-Benz CLS, it is actually cheaper than both.
The 6 Series GT is also at least as clean and frugal as those rivals with equivalent petrol and diesel engines, but we’d suggest both private buyers and company car drivers are best off going for the 630d diesel. It has the lowest CO2 emissions and the best fuel economy in the range, so not only makes the most financial sense but will also travel longer between fill-ups – that's a healthy bonus in a GT car.
There’s an extensive standard equipment list to tempt potential customers away from Audi and Mercedes, too. Entry-level SE trim gets everything you need and would be our pick, with standard kit including 18in alloy wheels, leather seats (heated in the front), climate control, sat-nav, Bluetooth, adaptive LED headlights, a sports multi-function steering wheel and front and rear parking sensors. M Sport models add larger alloy wheels, more aggressive styling and stiffer suspension in the pursuit of a more engaging drive, as well as a panoramic glass sunroof.
In its Euro NCAP crash tests, the 6 Series GT scored the maximum five stars, with good but not outstanding scores in some of the four categories evaluated, such as adult occupant protection. All versions come as standard with automatic emergency braking, which was deemed to be very effective, but unlike the A7 and CLS you have to pay extra for lane departure warning and assist.
