Coupe takes on German rival with easy access

Have your say

BMW’S 6 Series Gran Coupe is the marque’s first ever four-door coupe, a response to the very successful Mercedes-Benz CLS.

The svelte shape is practical, with fold-down rear seat backs to extend the boot, and a small centre seat for what BMW calls 4+1 seating. It introduces a new 450hp petrol V8 with figures of 0-62mph in 4.6 seconds, 26.6mpg (official combined average) and 206g/km of CO2. Prices for this 650i model start at £67,300. The cheapest model at launch is the 320hp straight six petrol 540i, at £61,380.

It combines 36.2mpg with 0-62mph in 5.4 seconds and 181g/km. The big seller will be the 540d (from £63,895), an advanced straight six diesel rated at 50.4mpg, 148g/km CO2 and 0-62mph in 5.4 seconds. At 197in long, the Gran Coupe is five inches longer than the two-door 6-series coupe (from £59,565) and sits on a stretched wheelbase. All versions have an eight speed automatic gearbox with stop-start and a fuel-saving ECO mode, brake energy scavenging and active air intake shutters. They produced at BMW’s largest factory, at Dingolfing, alongside the 5 and 7 series.
