BMW 4 Series Gran Coupé 2021: The family is complete

Following the arrival of its coupe and convertible versions, the 4 Series debuts this practical four-door bodywork.

Following the success of its first-generation, the BMW 4 Series Gran Coupé is back. We are talking about a four-door coupe that boasts a sharper aesthetic in line with the brand's new design language, an interior with high-quality materials, and a series of novelties in terms of services and connectivity. All this with improved driving dynamics and a sporty touch that is magnified by its high-performance version, which is accompanied by three other variants.

Four-door body

Compared to a standard 4 Series, this vehicle is almost two centimeters longer and six taller as its width remains at 1.85 meters, while the wheelbase also remains unchanged - 2.85 m. In addition, its tracks are wider since they measure 1.59 millimeters in front and 1.62 behind, that is, they gain 20 and 12 mm respectively. All this with a trunk whose capacity increases to 470 liters –30 l more–, expandable to 1,290 if the rear seatback sections are lowered, with a 40:20:40 division.

Aesthetically, we find a model that is defined by its bold lines and surfaces with a three-dimensional structure, highlighting above all the large front grill located in a vertical position. This is accompanied by full-Led headlights –with laser technology as an option– with U-shaped fiber-optic light strips for daytime running lights. On the side are frameless window doors, flush handles, 17-inch wheels, and a roofline culminating in a marked rear spoiler. Already at the rear, we discover a bumper with vertical aerodynamic lips on its outer edges and a black finish on its lower part.

Those wanting to add a sporty touch should opt for the M Sport trim or the BMW M trim. Optionally, the M Carbon exterior package is available, as well as the specific M Performance parts that are already available as part of the original BMW accessories range.

With regard to the interior, the German brand wanted to create an enveloping sensation in the sports front seats with the presence of a raised center console and the fluid-structure of the surfaces, ranging from the digital instrument panel to the door panels. As standard, the BMW Live Cockpit Plus is included, consisting of the iDrive operating system with an 8.8-inch central screen and another 5.1 ”display in the instrument panel (optionally these can be increased to 10.25 and 12.3 inches respectively), compatible with Apple CarPlay and Android Auto. The Sport leather steering wheel is also standard.

One diesel and three gasoline

In the mechanical section, we find four engines, one diesel, and three gasoline, these being the 420d, 420i, 430i, and M440i xDrive, with powers of 190, 184, 245, and 374 CV. All of them use blocks of four cylinders and 2.0 liters of displacement, except for the most performance version because it uses a 3.0-liter inline six-cylinder engine. In addition, both the latter and the diesel variant are assisted by a 48-volt light hybridization system, with a starter-generator that provides an additional 11 hp when accelerating out of a corner or when quick acceleration is needed.

The drag coefficient of the BMW 4 Series Gran Coupé (measured on the 420d) is 0.26.

Regardless of the engine chosen, the only transmission available is an eight-speed Steptronic Sport automatic transmission that has paddles on the steering wheel and a function called Sprint. This is responsible for ensuring that both the propulsion system and the gear change maximize their dynamic behavior when the driver demands a sudden increase in speed or overtakes.

Specific tuning

BMW says that it has achieved a weight distribution of almost 50:50 and that it has installed specific reinforcement bars between the turrets both in the front and in the area of ​​the rear axle, with the aim of improving the agility and precision of the vehicle. In addition, the geometry, mounting, and tuning of the chassis are specific to this model, with a double-link suspension at the front and five-link rear suspension, led by shock absorbers with controlled height adjustment as standard. Optionally, you can opt for the M Sport suspension or the adaptive M, which are accompanied by the variable sport steering, as well as M Sport brakes.

The prices of this car have not yet been revealed and its arrival at dealerships is expected in November. When it does, it will be equipped as standard with forwarding Collision Warning, Park Distance Control, Rear View Camera, Parking Assist, Lane Departure Warning, and Reverse Assist.
