The BMW 3 Series (G20) is a compact executive car produced by German automobile manufacturer BMW. It is the seventh and current generation of the 3 Series, and was unveiled at the 2018 Paris Motor Show on October 2, 2018,[1] and was released in March 2019.[2]

The M340i, one of the first models in the range will be available for sale in the spring of 2019, with the 330e hybrid model scheduled for launch in 2020.[3]

Development and launch[edit]

The G20 3 Series is based on the Cluster Architecture (CLAR) platform and features increased use of high-strength steel and aluminium.[4] The lead exterior designer was Marc Michael Markefka.[citation needed] The G20 has a double-wishbone front suspension and multi-link rear suspension,[5] with a hydraulic damping system to better absorb impacts.[6]

The G20 has a flat and covered underbody,[7] resulting in a reduced drag coefficient from 0.26 Cd to 0.23 Cd for the 320d.[8] Compared to its predecessor, the G20 is 55 kg (121 lb) lighter, 85 mm (3.3 in) longer, and 16 mm (0.6 in) wider.[9] The car retains a 50:50 weight distribution and has a 50% increase in body rigidity.[10] Boot capacity is identical to the F30, at 480 litres (17 cu ft).[11]

The windshield uses double-glazed acoustic glass and the A-pillars have increased insulation.[12] The handbrake is now electronically operated and no longer uses a manual lever.[13] Engine coasting is also now available in both Eco Pro and Comfort modes,[14] and both petrol and diesel models receive engine particulate filters.[15]

In November 2015, a final design proposal out of 3 total, was chosen by BMW management, as reported by Auto Bild in October 2015.[16]

The 320d and M340i are available in both rear-wheel drive and all-wheel drive (xDrive) variants.[17][18]

The Touring variant (G21) was launched on 12 June 2019.

An M3 version is under development and is expected to be launched in 2020.[19]


The G20 is available in Advantage, Sport Line, Luxury Line, or M Sport package.[20]

Standard equipment includes full LED headlights and tail-lights, automatic climate control, automatic headlights and rain-sensing wipers, 40:20:40 split folding rear seats, and driver assistance systems including lane departure warning and collision warning with braking intervention.[21]

All models feature iDrive 6.0 with an 8.8-inch display.[22] The system can be upgraded to Operating System 7.0 with a 10.25-inch display and 12.3-inch digital instrument cluster.[23] iDrive 7.0 has over-the-air updates for the navigational maps and operating system, and features a voice-controlled digital assistant that can be activated by saying "Hey BMW".[24] The assistant can control in-car functions and is integrated with Microsoft Office 365 and Skype for Business.[25] The engine start stop system uses the navigation system to prevent unnecessary engine shutdowns.

Optional equipment includes the BMW LaserLight, a BMW display key, self-righting wheel center caps, and a Welcome Light Carpet.[26] A Digital Key system enables a smartphone to lock or unlock the vehicle using near-field communication, and will start the engine when placed in the wireless charging tray.[27] The optional parking assistant system displays a three-dimensional 360 degree view of the car and its surroundings, which can also be remotely viewed in the BMW ConnectedDrive app.[28]

Only 318d and 320d models are available with a 6-speed manual transmission.[29]

BMW has controversially implemented a yearly fee for access to Apple CarPlay, a feature built into the car, and for which BMW pays no yearly fee or other ongoing expense.[30]

In March 2019 at the Geneva Motor Show the 330e iPerformance model was introduced, using the motor from the 320i and a 50 kW (67 hp) electric motor, it has a maximum electric range of 60 km (37 mi). It has a 12 kWh battery along with a newly developed system called "XtraBoost" allowing a temporary power increase from the electric motor of up to 30 kW (40 hp).[31]
