# BMW 6 Series (G32)

The G32 BMW 6 Series Gran Turismo is the second generation of the BMW Gran Turismo range of 5-door liftback executive cars launched in 2017, based upon the BMW 5 Series (G30). The 6 Series Gran Turismo is the successor to the BMW 5 Series Gran Turismo (F07) that was based upon the 5 Series (F10). A facelifted version of the 6 Series Gran Turismo was unveiled alongside the facelifted 5 Series on 27 May 2020. For 2021, all engines are 48 volt mild hybrids, assisted with a belt alternator starter. The 6 Series Gran Turismo was discontinued in August 2023 with no successor.
The BMW 6 Series nameplate had previously been used on the F06/F12/F13 grand tourers produced from 2011-18, which are also executive-sized (and was based on the contemporary 5 Series (F10), and besides the two-door convertible/coupé also included a four-door (F06 Gran Coupé, which like the G32 Gran Turismo has features of a four-door coupé like frameless doors and sloping rear roofline). However, the F06/F12/F13 would be succeeded by the 8 Series (G15).

## Development and launch

Details of the 6 Series Gran Turismo were released online on June 14, 2017. The car was later officially unveiled at the 2017 Frankfurt International Auto Show in September. The exterior was designed by Hussein Al-Attar.
Compared to the 5 Series Gran Turismo, the body of the 6 Series is 87 mm (3.4 in) longer, 21 mm (0.83 in) lower, and 150 kg (330 lb) lighter. The rear load compartment is 110 L (3.9 cu ft) larger at 610 L (22 cu ft). The 6 Series Gran Turismo is based on the modular Cluster Architecture (CLAR) platform and comes with self-levelling air suspension as a standard feature. The car automatically lowers by 9.9 mm (0.39 in) when travelling at speeds over 120 km/h (75 mph).
Initial models include two petrol engines, the 630i and 640i as well as the 630d which is one of the two diesel engines. The 640d is the second diesel model, which was released later in September 2017. The newest and smallest engine for the 6 Series GT is the 620d. This engine is available since July 2018 and will be the entry-level version for this lineup. All models are available as an all-wheel drive (xDrive) version. The 640d model is available only with all-wheel drive. Unlike the contemporary 5 Series (G30), as well as the preceding 5 Series Gran Turismo (F07) and 6 Series Gran Coupé (F06), no V8 engine was offered for the 6 Series Gran Turismo.

### Discontinuation

The only 6 Series GT to be sold in the USA was the 640i xDrive, for the 2019 model year, as the previous 6 Series (the F06-based Gran Coupé) was also offered in the 2019 model year. Both the Gran Coupé (final year of sale, as production ceased in September 2018) and the Gran Turismo (which continued to be available outside the USA) were discontinued in the USA market after the 2019 model year.
The 6 Series Gran Turismo was discontinued in August 2023 with no successor. Although the practicality of the 6 Series Gran Turismo was lauded while its looks were less awkward than the preceding 5 Series Gran Turismo, both vehicles had a mixed reception compared to the sleeker (but less practical) Audi A7.

## Equipment

The 6 Series Gran Turismo comes with a 10.25-inch screen featuring the latest version of iDrive 6.0, and is available with gesture control. BMW Active Driving Assistant is a standard feature on all models, and includes safety features such as: blind spot monitoring, lane departure warning and speed limit information. The 6 Series GT also features adaptive headlights, and many sensors to assist parking and motorway driving.

## Transmissions

* 8-speed ZF 8HP50Z automatic (630i / 640i / 640i xDrive)
* 8-speed ZF 8HP75Z automatic (630d)
* 8-speed ZF 8HP75X automatic (630d xDrive / 640d xDrive)
Also features manual sequential mode as well as sport shifting which holds the gears longer and spins the turbochargers.
