2020 BMW 4 Series Coupé revealed: price, specs and release date

New BMW 4 Series executive coupé gets bold looks and mild hybrid technology for some models, with a plug-in hybrid to come...

On sale: October | Price from: £39,870

Beauty is entirely subjective, and there’s no rulebook for creating a masterpiece. That’s why, despite the fact that it’s one of the most famous works of art in the world, some still look at Da Vinci’s Mona Lisa and see a slightly dowdy and entirely ordinary painting. And while some will gaze upon the new BMW 4 Series Coupé, with its gigantic front grille, and wonder what BMW’s designers were thinking when they created it, others will be clamouring to put one on their driveway.

The new 4 Series is bigger all round than the outgoing model, while its front and rear axles are farther apart. However, boot space has shrunk slightly compared with that of the existing model, meaning that while you’ll be able to pack more for your holidays than you could in the rival Mercedes-Benz C-Class Coupé, an Audi A5 Coupé can take more still. And like the current car, this 4 Series is a strict four-seater, although the rear bench can split and fold if you’re in need of more luggage space.

2020 BMW 4 Series engines

At launch, buyers can choose from three petrol engines and one diesel. The petrol range kicks off with a 181bhp 2.0-litre turbo in the 420i model and moves up through a 254bhp 2.0-litre turbo (330i) to a 3.0-litre six-cylinder turbo with 369bhp in the range-topping M440i, which has a 0-62mph sprint time that’s quick enough to beat a Porsche 911 sports car. Meanwhile, the 420d’s 187bhp 2.0-litre diesel promises fuel economy of up to 72.4mpg and a CO2 output of 103g/km. 

An eight-speed automatic gearbox is standard across the range, while four-wheel drive is optional on the 420d and standard on the 440i and is likely to be available on other variants in the future.

More powerful 282bhp 330d and 335bhp M440d models will arrive next March, while further off, a new plug-in hybrid 430e will feature a 2.0-litre petrol engine and electric motor to develop a combined 248bhp and offer at least 30 miles of electric-only range. 

A high-performance M4 super-coupé is expected to arrive later next year, producing 503bhp from its 3.0-litre six-cylinder petrol engine.

Diesel-engined versions of the 4 Series, plus the M440i petrol, now come with mild hybrid technology as standard. A 48-volt electrical system with a small battery harvests braking energy that can be redeployed to give the engine a boost under acceleration and ease the load at other times to help reduce fuel consumption.

Underneath, the 4 Series shares a lot with the 3 Series saloon, our favourite executive car as well as our favourite plug-in hybrid in 330e form. The two models are almost identical inside, too; that means you get high-quality materials and a class-leading infotainment system that’s easy to operate via a number of means, including a dial on the centre console. 

As standard, you get an 8.8in infotainment screen (which can optionally be upgraded to 10.25in) and a 12.3in digital instrument panel. Other options include a head-up display, a self-parking system and adaptive cruise control that can also offer steering inputs. Meanwhile, safety aids include automatic emergency braking with pedestrian and cyclist detection, speed limit detection and lane departure warning.

M Sport is the only trim available at launch, but buyers seeking to make their 4 Series stand out as much as possible can choose the new M Sport Pro Package, which adds a rortier sound from the exhaust in Sport driving mode, as well as 19in wheels and upgraded M Sport brakes.

2020 BMW 4 Series price

Prices start from £39,870 – a substantial increase on the current 4 Series but competitive next to the A5 and C-Class Coupé. The expected big-selling 420d M Sport, meanwhile, costs from £42,440. The pending arrival of the new model means discounts on the outgoing 4 Series are generous, with savings of up to £10,606 available through our New Car Buying service at the time of writing.

Don’t think we’ve forgotten the 4 Series Convertible, either. A successor to today’s open-top 4 Series is already waiting in the wings and is likely to go on sale next year. As part of weight-saving measures, it’s expected to revert back to a fabric roof, rather than the heavy folding metal roof of today’s car.
