Chronology
PredecessorBMW 3 Series (F30)

The M340i, one of the first models in the range became available for sale in the spring of 2019, with the 330e plug-in hybrid model scheduled for launch in 2020.[4] The 3 Series Gran Turismo fastback body style was discontinued for the G20 generation.[5]

Development and launch

At the end of November 2015, a final design proposal for the successor of the F30 3 Series by Alexey Kezha out of 3 total, was chosen by BMW management, as reported by Auto Bild in October 2015.[6] The new 3 Series, internally called the G20, was unveiled at the 2018 Paris Motor Show on October 2, 2018,[7] and was available for sale in March 2019.[8]

The G20 3 Series is based on the Cluster Architecture (CLAR) platform and features increased use of high-strength steel and aluminium.[9] The G20 has a MacPherson strut front suspension and multi-link rear suspension,[10] with a hydraulic damping system to better absorb impacts.[11]

The G20 has a flat and covered underbody,[12] resulting in a reduced drag coefficient from 0.26 Cd to 0.23 Cd for the 320d.[13] 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.[14] The car retains a 50:50 weight distribution and has a 50% increase in body rigidity.[15] Boot capacity is identical to the F30, at 480 litres (17 cu ft).[16]

The windshield uses double-glazed acoustic glass and the A-pillars have increased insulation.[17] The handbrake is now electronically operated and no longer uses a manual lever.[18] Engine coasting is also now available in both Eco Pro and Comfort modes,[19] and both petrol and diesel models receive engine particulate filters.[20]

The 320d and M340i are available in both rear-wheel drive and all-wheel drive (xDrive) variants.[21][22]

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

The long-wheelbase variant in China was launched on April 2019 as a single trim, the 325Li, which uses a 2.0 liter turbocharged engine making 184 HP and 300 Nm (221 lb-ft) of torque mated to a 8-speed automatic transmission as the only transmission offered. The wheelbase was extended by 110 mm (4.3 in).[23] The right hand drive LWB variant in India, the 330Li, is scheduled for release by 2021 to replace the 3 GT. The 330Li uses a 2.0 liter turbocharged engine making 258 HP.[24]

An electric version for the Chinese market is scheduled for release by 2023.[25]

Equipment

The G20 is available in Advantage, Sport Line, Luxury Line, or M Sport package.[26]

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.[27]

All models feature iDrive 6.0 with an 8.8-inch display.[28] The system can be upgraded to Operating System 7.0 with a 10.25-inch display and 12.3-inch digital instrument cluster.[29] 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".[30] The assistant can control in-car functions and is integrated with Microsoft Office 365 and Skype for Business.[31] 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.[32] 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.[33] 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.[34]

Only 318d and 320d models are available with a 6-speed manual transmission.[35]

BMW had 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.[36] As of December 2019 it is reported that this fee will no longer be charged as BMW has backtracked on this decision.[37]

In March 2019 at the Geneva Motor Show the 330e iPerformance model was introduced, sharing its engine with 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 (9.6 kWh usable) along with a newly developed system called "XtraBoost" allowing a temporary power increase from the electric motor of up to 30 kW (40 hp).[38]
