One year after the 3 Series, BMW also reissues the 4 Series. The Coupé not only differs in name from the mid-range sedan, but it also runs its way technically and optically.
A year ago, BMW relaunched the mid-range bestseller 3 Series and touring followed in late 2019. Now it’s time for the next step: the new 4 Series Coupé. In the past generation, the Munich-based company had renamed the sporty two-door from 3-series to 4-series, with the new edition rolling out to the dealer in October 2020 (base price: from 45,800 euros), the carmaker differentiated the two models even more clearly – optically and technically!
BMW 4-Series Coupe Design
Of course, the new 4 Series also uses numerous parts from the 3 Series shelf. Nevertheless, the coupé looks significantly sportier than a 3 series with two doors. Mainly because the 4 Series is almost six centimeters flatter than the sedan. There is also a 23 millimeter wider track on the rear axle, which gives the BMW a muscular rear. The difference to the classic 3 Series is most obvious on the front: Here is a mega double kidney.
We already know this from the IAA Concept 4 study. Unlike the usual, the large grill was not just traded fair bling, but also made it into the series. Depending on whether you choose the basic 4-seater or the sport version, the Munich man appears more or less aggressively. Large air intakes and a jagged rear mark the M aerodynamics package and give a first taste of what an upcoming M4 (probably with up to 510 hp) will bring. Without the extra sports insignia to be paid for, the 4 Series relies on restrained elegance, but in no way appears inconspicuous.
The 3 and 4 series are quite similar in the interior: Anyone entering the cockpit through the large doors with frameless windows will find themselves in the typical BMW world. You sit lower than in the limousine or in the touring, the view to the rear is a bit more restricted. But the interior is well known. And: Despite digital instruments, a large infotainment touchscreen, or a digital voice assistant, the 4 Series still looks like it has been used for years. If you are looking for a high-tech world with giant displays and a reduced cockpit looks, you have to look elsewhere.
BMW 4-Series Chassis
In addition to the significantly more dynamic body, the new 4 Series also differs technically from its basic brother. The wider track on the rear axle not only ensures a cooler look but also contributes to the driving dynamics. Just like more camber on the front axle and the center of gravity lowered by a total of 21 millimeters. Also, aerodynamic finishing and a mini rear spoiler on the trunk lid ensure less buoyancy.
Also, BMW has put a lot of brain pain – and money – into the revision of the chassis: Additional struts in the front end between the strut towers and the body as well as in the rear are intended to improve the responsiveness of the steering and the rigidity of the entire vehicle. Also, the stroke-dependent shock absorbers were designed tighter and fine-tuned in the direction of sportiness.
Of course, if you want, you can still get an adaptive chassis with which the base can be adapted to your taste. And as with the 3 Series, there is of course also a limited-slip differential on the rear axle in the 4 Series, which sends the power to the wheel with the most grip.
BMW 4-Series Engine
Apropos power: First, the provisional top model M440i provides up to 374 hp – plus 11 hp, which the mild-hybrid system contributes. The inline six-cylinder with three-liter displacement is the first BMW petrol engine with 48-volt technology. It should boost noticeably when starting and accelerating – in addition to the already generous 500 Nm of torque of the Otto engine. Because the burner is relieved, the system also reduces fuel consumption. According to BMW, the all-wheel-drive M440i crushes an average of 7.1 liters on 100 kilometers on paper.
Beneath row six is two two-liter turbo four-cylinder with 184 hp (420i) and 258 hp (430i). The reverse is true for diesel engines: only the 190 hp 420d has four combustion chambers, 430d (286 hp), and M440d (340 hp) rely on three-liter six-cylinder power. The two more powerful diesel always come with all-wheel drive, but will only arrive in March 2021; 4×4 technology is optional on the 420d. The eight-speed automatic is set for all engines, at least for the time being.
The prices for the new 4 Series start at 45,800 euros for the 420i Coupé, the 430i starts at 50,800 euros. For the top model M440i at least 66,900 euros have to be put on the table. The 420d costs 48,300 euros with rear-wheel drive, with all-wheel drive 50,800 euros. Compared to the 3 Series Sedan, this is a surcharge of around 5000 euros, only with the M440i is BMW satisfied with an extra charge of “only” 3900 euros. In the predecessor model, the 4 Series was only a good 3500 euros more expensive than the 3 Series. The coupé will be launched in October 2020. The convertible will follow in spring 2021, and BMW will then push the four-door Gran Coupé in summer 2021.
