BMW no longer offers the 6 Series in the United States, but an updated version of the oddly proportioned 6 Series Gran Turismo is set to land in Europe with a modified body design and refined interiorIn addition, the slope-roofed hatchback gets a jolt of electricity with mild-hybrid systems plugged into every 6 Series engine option.

The dimensions of the 5.09-meter (16.7-foot) 6-seater GT remain unchanged. The passenger compartment, which is set far back between the long 3.07-meter (120.8-inch) wheelbase continues to shape the look. There are also frameless windows and the large tailgate as well as the rear spoiler that extends automatically at speed above 120 km/h (75 mph). The luggage compartment volume is pretty much identical to the previous generation, with 600 to 1,800 liters (21.2 to 63.5 cubic feet) of storage available, depending on the rear seats being up or folded.

The visual innovations include new contours for the BMW kidney grille and the headlights immediately adjacent to it. There are also redesigned front and rear aprons, and an M-Sport package with new elements and trapezoidal tailpipe trims is offered on all models. The lower air intake is now divided up differently to emphasize the vehicle width. The photos below offer a comparison between the outgoing generation (left) and the new model (right).

The standard equipment also includes electrically adjustable front seats and leather interior. Multi-function seats and a rear bench seat with an electrically adjustable backrest angle are optionally available. Other options include new interior trim, ambient light with a new dynamic interior light, a four-zone automatic climate control, a panoramic glass roof, a surround sound system from Bowers & Wilkins, and the latest version of the Rear Seat Entertainment Professional system.

48-volt mild hybrid system for all engines

BMW is continuing to electrify its models. All variants of the new 6 Series GT will have a 48-volt mild-hybrid system as standard equipment. The mild-hybrid setup includes an electric motor that acts as a starter and generator, and is intended to increase efficiency through both overall efficiency and power. BMW says the hybrid system adds 11 horsepower (8 kilowatts) to the 6 Series GT. Braking energy is stored in an additional 48-volt battery.

Part of the efficiency promise comes through the use of BMW's start-stop system controlled by the electric motor. Not only does it allow the engine to shut down at stops, but it can shut off and uncoupled from the gearbox while slowing at speeds under 15 km/h (9 mph). The start-stop system can be disabled in certain drive modes, but for the new 6 Series it's available in Eco Pro and Comfort settings.


At the market launch, two gasoline engines and three diesel mills are available, including two four pots and three six-cylinder engines, all of them with cylinders in-line.

  Engine HP (KW) / TQ (Nm / Lb-Ft) 0-100 km/h (0-62 mph)
630i 2.0L Inline 4 gasoline 258 HP (192) / 400 / 295 6.5 seconds
640i xDrive 3.0L Inline 6 gasoline 333 HP (248) / 450 / 332 5.5 seconds
620d 2.0L Inline 4 diesel 190 HP (142) / 400 / 295 7.9 seconds
630d xDrive 3.0L Inline 6 diesel 286 HP (213) / 650 /479 6.1 seconds
640d xDrive 3.0L Inline 6 diesel 340 HP (254) / 700 / 516 5.3 seconds

All engines meet the Euro 6d emissions standard and send power to a standard-issue eight-speed automatic. In addition to a twin-scroll turbocharger, the two gasoline engines have direct injection at a maximum pressure of 350 bar (previously 200 bar). All three diesels now have two-stage charging. The four-cylinder diesel also has direct injection via new solenoid valve injectors that work at up to 2500 bar. For the first time, the two 3.0-liter diesels have step charging. It is combined with direct injection via piezo injectors with up to 2,700 bar.

The standard eight-speed Steptronic has also been improved. The new version is lighter and has a wider spread. The transmission control also shifts down early, for example, when approaching an intersection or a vehicle in front. There is also an optional "Steptronic Sport" gearbox with eight cogs. This gearbox includes shift paddles on the steering wheel as well as launch control.

All-wheel-drive is available as either standard or optional for three model variants. The basis is an electronically controlled multi-plate clutch, which normally transmits the power to the rear wheels but can shuffle it forward if needed.

The chassis has a rear axle air suspension with automatic level control as standard. Air suspension is also optionally available for the front axle. Other chassis options include rear-wheel steering ( called integral active steering), and active roll stabilization. A sports brake system with blue or red brake calipers is also available.

Driver assistance systems

The driver assistance systems of the 6 Series GT have also been updated. The lane departure warning included in the optional Driving Assistant now also leads back to the road, by means of steering assistance.

The Driving Assistant Professional, which is also available as an option, includes the steering and lane guidance assistant, whose range of functions has been expanded to include active navigation guidance. The system recognizes necessary lane changes based on navigation data, which the driver can execute using the lane change assistant. There is also a new emergency lane assistant that automatically guides the car to the edge of the lane in a traffic jam.

The parking assistant system now also takes over the steering movements when reversing over a distance of up to 50 meters. With the new drive recorder function, video recordings of up to 40 seconds of what is happening around the vehicle can also be captured and saved.

The new  BMW Operating System 7 also finds its way into the 6 Series Gran Turismo. It is not only intended to improve operation, but also enables services such as BMW's new cloud-based navigation system and over-the-air updates.

Market launch for the new 6 Series GT slated for July 2020. The base price is €62,800 EUR (approximately $69,000 USD). The car is produced in Dingolfing, Bavaria, where the BMW 7 and 8 series are also produced.
