The figure that’s likely to convince those who see a clear and rational case for 6 Series GT ownership may simply be the difference between the price of this car and an equivalent full-sized limo such as a 7 Series or an S-Class. That can be the thick end of £20,000.
Given that the 6 Series’ refinement, equipment sophistication and occupant space are fully commensurate with a full-sized executive limo and in some ways (cargo space, visibility) it even offers more, you could see why that might seem like a good deal if you’re not put off by the car’s somewhat unconventional appearance.
BMW’s big ‘value’ message with the car is that it’s effectively the same price as an equivalent 5 Series once you load up the smaller car with the same equipment. The 6 Series GT is certainly a well-equipped car.
As well as a surprisingly frugal one. Our 630d GT produced a touring test fuel economy result of 54.5mpg in Eco Pro driving mode.
The Mercedes S350 Bluetec saloon we tested in 2013 was fully 10mpg short of that standard.
On that basis, it should be capable of putting almost 600 miles between fuel stops, which high-mileage business commuters will surely appreciate.
The car’s 154g/km CO2 emissions rating should also make it competitive with most big-engined diesel executive saloons on benefit-in-kind tax.
