BMW 6 Series Gran Coupé (F06): engines, trims and buying
BMW 6 Series Gran Coupé (F06) — a luxurious four-door coupe-style car produced from 2012 to 2018. It combines luxury, space and sporty driving. In this article, we review the engines, trims and what to check before buying a used one.
6 Series Gran Coupé in brief
The Gran Coupé is the four-door version of the 6 Series family, based on the 5 Series platform. It's longer than the coupe and convertible, so there's more room in the rear seats and a larger boot (around 460 litres).
This is a luxurious, smooth and fast car, perfect for long journeys. Today, it looks modern and often costs less than a comparable Mercedes-Benz CLS or Audi A7.
Which version to choose
Production was within one generation (F06), and in 2015 the car was refreshed: it received new LED headlights, a redesigned bumper design and an improved multimedia system. In the used market, it's worth choosing a car produced after the refresh.
As well as the standard versions, there was the M6 Gran Coupé with a 4.4-litre V8 engine (around 560 hp). In this case, it's a whole different category in terms of price and maintenance.
Engines and gearboxes
Petrol: 640i with a 3.0-litre inline six-cylinder engine (around 320 hp) and 650i with a 4.4-litre V8 (around 407 hp, around 450 hp after the refresh). Diesel: 640d with a 3.0-litre engine (around 313 hp). Most versions are available with xDrive four-wheel drive.
All cars have an eight-speed automatic gearbox. It operates smoothly and is well-matched with the engines.
What to check when buying a used 6 Series Gran Coupé
Request a full service history. Large and powerful engines, especially V8s, are sensitive to oil quality and service frequency. Pay attention to oil leaks and the condition of the cooling system.
Check the suspension — the car is heavy, so shock absorbers, springs, and anti-roll bar links wear out quickly. If it has adaptive suspension, test all modes.
Test all the electronics: multimedia (iDrive), cameras, parking sensors, heated seats, and electric adjustments. Repairs can be expensive, so it's better to know in advance.

Frequently asked questions
How does the Gran Coupé differ from the 6 Series coupé?
The Gran Coupé has four doors and a longer wheelbase, so there's more room in the back. The coupé and convertible are two-door versions, more sporty but less practical.
Which engine is the best?
For most buyers, the best is the 640d diesel, as it's economical and powerful enough. If performance and sound matter, go for the 650i with V8.
Is it worth buying a car before the 2015 update?
Yes, if its condition is good and the price is attractive. After the update, the car got LED headlights and improved multimedia, so these cars often justify the extra cost.
