The second generation of the BMW 4 Series consists of the BMW G22 (coupé version) along with the BMW G23 (convertible version) and BMW G26 (5-door liftback version, marketed as the Gran Coupé) compact executive cars. The G22 4 Series was launched in June 2020 and succeeds the F32 4 Series.

The G22 will be produced alongside - and shares many features with - the G20 3 Series. As with the G20 3 Series range, the 4 Series are powered by turbocharged petrol and diesel engines. Unlike its predecessor, the new 4 Series has a significant departure in design from the 3 Series in order to distinguish between the two models and to move the 4 Series upscale. The most notable of the design changes is the large kidney grille at the front which was inspired by the 1930s BMW 328.

Development

The G22 4 Series was unveiled in concept form as the BMW Concept 4, at the 2019 Frankfurt Motor Show and previewing the next generation of the 4 Series. The most notable design feature is the large vertical kidney grille which is inspired by the BMW 328 and 3.0 CSi respectively. The grille has a 3D pattern design to give it a more pronounced look. Other notable design features of the concept were a pronounced duck-tail spoiler at the rear, thin wing mirrors made from a single piece of aluminium and open headlamps, which have no covering over their 3D lighting elements and are instead embedded into the body of the car.

Launch

On 26 May 2020, BMW announced that the G22 4 Series would be unveiled online in June 2020 by posting a teaser image of the range-topping M440i model. More than 80% of the design cues from the Concept 4 were carried over to the production version including the large kidney grille which now has mesh inserts and is flanked with two slim LED headlamps and two large air intakes (exclusive for the M440i). The rear features wrap around tail lamps and a lip spoiler which is exclusive for the M Sport models. The silhouette of the car is similar to the 8 Series with a tapering roof line. The rear bumper comes with a diffuser on the M Sport models with the M440i having dual exhaust tips. The production version is claimed to have a drag area as low as 0.25 x 2.19 m² for the Coupé. On the online unveiling, BMW announced that the worldwide launch of the G22 4 Series would be held in October of the same year.

At the end of September, BMW unveiled the convertible version of the new 4 Series (G23), with the same technology and engines as the coupe. It has a canvas roof, unlike the two predecessors which had a retractable hardtop.

Models

The launch models consist of the diesel engine 420d, 430d and M440d, the petrol engine 420i M Sport and 430i and the mild hybrid M440i xDrive. The 420i M Sport and 430i feature the 2.0-litre BMW B48 inline-4 engine; rated at 135 kW (181 hp) and 300 N⋅m (221 lb⋅ft) of torque for the 420i M Sport, and 190 kW (255 hp) and 399 N⋅m (294 lb⋅ft) of torque for the 430i. The M440i model is powered by the 3.0-litre turbocharged BMW B58 Inline-6 engine rated at 285 kW (382 hp) and 500 N⋅m (369 lb⋅ft) of torque equipped with a 48-volt electric motor rated at 8 kW (11 hp).

The M440d, like the M440i, is also equipped with a mild hybrid system. The hybrid system features a belt-fed starter generator to recoup energy under braking. This power can be supplied to the car’s 12V electrical system or deployed to assist the combustion engine to help reduce CO
₂ emissions and boost fuel economy.

A previously unavailable combination of the 430i with xDrive in their Gran Coupé body will be available as a MY23 version becoming the first 2023 model other than their "iX" electrified SUV. Popular options like a Harman Kardon stereo upgrade, heads-up display and LASER headlights are all available. Orders accepted beginning March according to BMW of NA publications.
