2020 BMW 4-series Coupe teased – to debut next week

BMW’s 4-series Coupe and its chunky new grille is ready for its reveal on June 2

The new BMW 4-series will be officially revealed on June 2nd, ending months of speculation over what’s sure to be the most controversial new BMW in years. As has been established from both previously sighted prototypes and the Concept 4-series BMW revealed at last year’s Frankfurt motor show, the new 4-series will introduce a new face for BMW.

As seen in this lightened teaser image, quite literally front and centre is the 4-series’ new kidney grille, which extends behind the number plate and down to the base of the front bumper. This look has been controversial throughout its speculation, but should become an even hotter topic when we see the car in full

As was previously revealed by BMW, topping the 4-series Coupe range will be the M440i xDrive, a rival to the Audi S5 and Mercedes-AMG C43 Coupe. It will be powered by the same turbocharged inline-six petrol engine as the M340i saloon and estate, but differs by integrating a new 48V mild hybrid system to assist the engine at low engine speeds. Comprising an 11bhp electric starter/generator and a secondary small-capacity lithium ion battery. The system not only improves efficiency, but also provides a subtle boost at low engine speeds.

Total system output of the powertrain is rated at 372bhp, identical to the M340i saloon and estate, but it should feature a slightly flatter power and torque curve due to the electric assistance at low rpm. Power is sent to the same eight-speed ZF torque converter automatic transmission and xDrive all-wheel drive system too, assisted by BMW’s M Sport active differential on the rear axle. The M440i will also include a bigger brake package than standard models as well as an 18-inch wheel and tyre package.

BMW has also revealed details about the new coupe’s body and chassis, confirming that like the previous generation, the new 4-series will be lower and wider than the corresponding 3-series saloon. The sloping roofline sits 57mm lower, helping achieve a 21mm drop in the coupe’s centre of gravity, while the rear track is 23mm wider. The suspension design itself is unchanged – including double joint spring struts at the front and a five-link independent rear – but it has been retuned to suit both the 4-series’ wider track and different geometry. 

Engineers have also paid close attention to increasing the structural stiffness of the body shell, with a new shear panel fitted across the bulkhead and bespoke bracing across the engine bay connecting the front strut towers to the crash structure. With a focus on increased dynamic performance and feedback in the 4-series coupe, structural improvements create a better foundation for engineers to hone components like the adaptive suspension more accurately, improving both handling and stability. 

It’s the 4-series’ most controversial new feature that’s still under wraps though. As we’ve seen in multiple concepts and leaked images, the new 4-series will push BMW design further away from its elegant predecessor, incorporating a new interpretation of the classic kidney grille to greater proportions even than the new 7-series and X7 SUV. Alongside the dramatic new face, BMW has also pushed the overall design further away from the traditional three-box coupe form iconic of two-door 4-series (and 3-series Coupe models before it), with a sloping roofline, tapered cabin and flat tail in the style BMW’s flagship 8-series Coupe. 

The 4-series Coupe will also spawn Cabriolet and Gran Coupe body variants, and form a base for the next M4, which will still optionally feature a six-speed manual transmission and rear-wheel drive – be that switchable as in the current M5 or full-time. But this is a BMW ready to cause quite some design controversy when it’s finally revealed next week when there will be no more hiding behind any rudimentary camouflage. That’s something BMW has experienced when former design chief Chris Bangle was at the helm too of course, and that certainly didn’t harm BMW sales.
