S o in theory, the BMW 4 Series Coupé is little more than the coupe variant of the BMW 3 Series. But with that alone you can't win a flower pot today. BMW says customers would have liked a clear visual differentiation between the 3 Series Sedan and the 4 Series Coupé, including an overall very sporty design. So the designers got started and started right at the beginning with the much discussed big kidney. It gets the so-called mash grill, which was previously reserved for M models. Parking sensors are located in two of their meshes, and a plastic disc behind which the distance radar works can be seen in the lower area. The designers made the front headlights extra flat so that the 4 Series Coupé appears wider. LED light is part of the standard scope of delivery, laser light is available for an extra charge.
Lower than the sedan
The doors have frameless windows and a strong shoulder extends across the rear wheels. The LED rear lights are again flat and, in combination with the wide wheel arches, ensure an enormous visual presence even when looking from behind.
In length, the 4 Series Coupé has increased by 128 millimeters to 4 compared to its predecessor .77 meters, in width by 27 millimeters to 1.85 meters and the wheelbase has increased by 41 millimeters to 2.85 meters. The height is just six millimeters up to 1.38 meters - compared to the sedan, the Coupé is 57 millimeters lower. There are significant surcharges for the gauges with 18 millimeters at the front and 23 millimeters at the rear.
Sport leather seats series
The cockpit of the 4 Series Coupé hardly differs from that of the 3 Series. Striking: the sports leather steering wheel and sports leather seats with adjustable headrests are part of the standard equipment. In addition, acoustic glazing for the windshield and three-zone air conditioning are already included ex works. The start /stop button is now in the center console. The backrest in the rear can be folded down in a 40: 20: 40 ratio at the push of a button in the trunk. The trunk volume is 440 liters.
Additionally stiffened at the front and rear
As the 4-series coupé is designed as a fun driving machine, it gets its own chassis set-up. For more rigidity, the engineers have integrated additional struts in the engine compartment, which surround the engine like a framework. Further reinforcements are located on the rear axle. Compared to the 3 Series Sedan, the 4 Series Coupé is 21 millimeters lower. The dampers work with the standard chassis as well as with the M chassis, which are subject to a surcharge.
Head-up display 70 percent larger
When it comes to assistance systems, there are the same extensive range for the 4 Series Coupé as for the 3 Series. The front collision warning system with brake intervention, the lane departure warning system with active lane return and the Speed Limit Info are standard. New features include a reversing assistant and a video recorder that saves 40-second sequences of the vehicle's surroundings. For more comfort and safety, there is the optional head-up display, the display area of which has grown by 70 percent.
BMW combines the engine of the M440i xDrive and the diesel engines in the 4 Series Coupé with a 48-volt mild hybrid system. This enables braking energy to be recovered and acceleration processes to be supported with eleven additional electric horsepower. The straight six cylinder of the M440i develops 374 hp. It is joined by two four-cylinder petrol engines: the 430i has 258 hp, while the 420i has 184 hp. The diesel range starts with the four-cylinder in the 420d (190 hp) and will continue, probably from March 2021, with the in-line six-cylinder 430d and M440d. The xDrive all-wheel drive system is standard on the M440i, M440d and M430d, and there is an extra charge for the small diesel. An eight-speed automatic is always responsible for the power distribution.
Surcharge compared to 3 Series Sedan
Deliveries of the new BMW 4 Series Coupé built in Dingolfing will start in October 2020. The prices are not yet known , only the surcharge for the M440i Coupé compared to the corresponding 3 Series sedan has already been communicated: 5,000 euros. That sounds like a lot at first, but it can be calculated a bit: This surcharge includes the sports package with the sports seats and the 48-volt mild hybrid system with a total value of around 3,500 euros. That leaves a price that is 1,500 euros higher than that of a comparably equipped 3-series sedan.
