Which is the most popular engine in the BMW 6 Series?

The diesel engine has been the most popular by far. Enthusiasts love the efficiency and speed of the 640d with its 313bhp which gives it a 0-62mph time of 5.5 seconds, which is still capable of 40+mpg.

Which are the most popular model variants?

BMW has offered several model variants, such as SE, Sport and M Sport. The M Sport has been the most popular with its unique paint schemes, special bodykit, 19-inch alloy wheels, available Nappa leather sports seats, M Sport steering wheel and upgraded badging.

What optional extras should I look out for?

Buyers of a used BMW 6 Series should look out for the larger alloy wheels, and there are also some sporty upgrades worth looking for, such as gear paddles on the back of the steering wheel and piano black wood.

Is the BMW 6 Series a good family car?

Yes, the 6 Series Gran Coupé (which is actually a saloon) is the most spacious of the group, offering enough room for adults in the back seat. It also has the largest boot, which is very spacious with the back seat folded down.

Is there a hybrid version of the BMW 6 Series?

No, BMW didn't make a hybrid 6 Series. Instead, petrol and diesel engines were offered while the vehicle was in production, with the diesel providing the best overall fuel economy.

Is the BMW 6 Series available as an automatic?

Yes, the 6 Series offered both an automatic and a manual gearbox. The manual options have been much more difficult to find, with most used cars having the automatic transmission.

Is there a four-wheel drive version available?

Yes, some models have BMW's xDrive all-wheel drive system for added traction and better handling. However, most of the used 6 Series models come with rear-wheel drive.

Different generations of used BMW 6 Series

The very first 6 Series arrived in 1976, known as the BMW E24. At the time, it was the fastest four-seater coupé available. BMW had released four generations of the 6 Series, all with varying bodystyles and powertain options. With each new generation and refresh, BMW included more technology and comfort features, adding to the desirability. However, the 6 Series lineup was discontinued in 2020, replaced by the 8 Series.

Fourth Generation (2017 to 2020)

With the discontinuation of other bodystyles, only the 6 Series Gran Turismo continued into the fourth generation. This agile sports car was lightweight because of the high-strength steel and aluminium construction. A rear axle air suspension and optional adaptive suspension added to the comfort of the cabin.

The 6 Series Gran Turismo is known for its coupé-like profile with the sloping roof. It offers a sports-car feel combined with elegance, while there is a spacious and luxurious cabin.

Fuel type:: Diesel / Petrol
Engine Size:: 2 - 3
MPG:: 29 - 58
Acceleration:: 5.2 - 8 seconds

Third Generation (2011 to 2018)

From an exterior viewpoint, the 6 Series had clearly defined lines and a flat, broad silhouette. The free-standing Control Display found in the cabin added to the premium, high-class feel. There was also a convertible model available with a fabric roof for even more on-road enjoyment. In 2012, the 6 Series Gran Coupe was released, giving the lineup a larger option for added comfort.

A 2015 facelift gave the lineup new kidney grilles on the front and updated rear aprons that emphasised the width of the car. There were also new paint finishes, LED headlights and a Hi-Fi stereo available from 2017.
