The new BMW 4 Series Coupé gets a sleek and distinctive new exterior design, premium interiors, upgraded driver assistance technologies and even greater efficiencies from the introduction of the mild hybrid technology.
At 4,768 millimetres, the new car is 128mm longer than its predecessor and 27mm wider (now 1,852mm), and its wheelbase has grown by 41mm to 2,851mm. Only 6mm has been added to the vehicle height, which is now 1,383mm. Increased track widths (+ 28mm at the front and + 18mm at the rear). Short overhangs, slender pillars, long doors with frameless windows and a flowing roofline combine to deliver a sleek look.
A defining element of the striking front end is the BMW trademark kidney grille and, with its upright elements connected in the centre, it reprises a design feature from the company’s past but adds a modern twist. Full-LED headlights are fitted as standard, with two U-shaped fibre-optic light guides in the lower section serving as the daytime driving lights. Adaptive LED Headlights with BMW Laserlight, including BMW Selective Beam non-dazzling high beam assistant, are available optionally. Slim LED fog lights are standard on all models except the BMW M440i xDrive Coupé and BMW M440d xDrive Coupé.
The 4 Series will go on sale with three petrol engines and one diesel. Two 2.0-litre four-cylinder petrols offer 181bhp (420i) and 254bhp (430i), while a 48V mild-hybrid 2.0-litre four-cylinder turbo diesel delivers 187bhp (420d) and official fuel economy of between 67.3 and 72.4mpg.
The range-topper will be the M440i xDrive, producing 369bhp and 369lb ft from a 48V mild-hybrid 3.0-litre six-cylinder turbo petrol engine. It’s claimed to be capable of 0-62mph in 4.5sec, a top speed of 155mph and fuel economy of 39.8 to 41.5mpg.
Mild-hybrid six-cylinder diesels producing 282bhp (430d) and 335bhp (M440d) are due next March.

| 420d M Sport | 190 | 400 | 7.1 |
| 420d xDrive M Sport | 190 | 400 | 7.4 |

This is the first time that every BMW 4 Series Coupé has been fitted with an eight-speed Steptronic transmission as standard. M Sport cars feature a Sport ’box that’s optional on other models; in addition to quicker shifts, this brings launch control and a new driving mode named Sprint.
Rear-wheel drive is standard except on the M440i, 430d and M440d; four-wheel drive is also optional on the 430i and 420d.
The new BMW 4 Series Coupé utilises an enhanced version of the 3 Series Saloon chassis to offer improved handling and reinforce its sporting character. An almost completely sealed underbody, improved air flap control and numerous other measures have led to a reduction in drag, reflected in a Cd as low as 0.25 (BMW 420d Coupé). The extra 23 millimetres of track width at the rear axle compared with the new BMW 3 Series Saloon, 50:50 weight distribution and a centre of gravity that is 21 millimetres lower than the Saloon significantly aid agility.
Customers can tailor the driving experience with options that include M Sport suspension, Adaptive M suspension with variable sport steering, M Sport brakes and the M Sport differential.
Inside the 4 Series, you’ll find a very traditional BMW cockpit. Familiar buttons and knobs angle toward the driver, and there are few extreme curves or angles in sight. Standard equipment features an 8.8-inch infotainment screen and a 5.1-inch screen nestled between physical gauges in the instrument panel, but a 10.25-inch instrument display is optional, as is a 12.3-inch infotainment screen. A sunroof and wireless Apple CarPlay and Android Auto come standard, too, along with a host of safety features including blind-spot monitoring, automatic emergency braking with pedestrian recognition, automatic high-beam headlights and lane-departure warning. Adaptive cruise control, lane-keep assist and parking cameras and sensors are optional.
The new BMW 4 Series Coupé will be built at BMW Plant Dingolfing, with its worldwide launch commencing in October 2020.
