The new BMW 2 Series Coupé completes its driving dynamics tuning and testing run.

The final phase of the series development process for the new edition of the BMW 2 Series Coupé has begun with the dynamic testing and tuning of its drive and suspension systems under racetrack conditions. The two-door compact sports car includes numerous features, carefully coordinated during the test drives. The new BMW 2 Series Coupé in the competitive environment have the rear-wheel-drive setup, an extremely powerful in-line 6-cylinder engine, the almost 50:50 balanced axle load distribution, an exceptionally torsionally stiff body and chassis technology consistently designed for agile and dynamic driving behaviour.

During the development of the new BMW 2 Series Coupé, the test and tuning drives on the Nürburgring's Nordschleife serve as the ultimate test for wheel suspension, chassis, damping, steering and braking system. In addition, testing on public country roads around Munich and at the BMW Group test site in Maisach ensure that the dynamic driving qualities of the new BMW 2 Series Coupé can also be experienced in everyday traffic and under different road conditions.

By extensively testing all drive and chassis systems, the development and test engineers ensure that the engine's performance characteristics go hand in hand with precisely controllable handling in every situation. The marque achieves fascinating cornering dynamics, optimised traction in all weather and road conditions and perfectly balanced ride comfort. At the same time, the car is fine-tuned to optimise self-steering behaviour and dynamics when building up lateral acceleration forces. The power transmission to the rear wheels, which is unique in the segment of the new BMW 2 Series Coupé, is ideally suited to sporty, ambitious cornering, including easily controllable drift manoeuvres.

The new BMW 2 Series Coupé's focus on maximum driving dynamics in the segment is embodied by the BMW M version at the top of the model range. The BMW M240i xDrive Coupé top model (fuel consumption combined: 8.2 l/100 km, combined CO2 emissions: 186 g/km; provisional value according to WLTP) draws its drive torque from a potent in-line 6-cylinder petrol engine with BMW TwinPower Turbo technology. The drive, which is as spontaneously responsive as it is powerfully thrusty, generates a maximum output of 275 kW/374 hp and is combined with an 8-speed Steptronic Sport transmission. The BMW M model puts its power to the road using the intelligent BMW xDrive all-wheel-drive system. The system's rear-wheel oriented design ensures hallmark BMW driving pleasure in conjunction with a power distribution that adapts perfectly to adverse road and weather conditions.

The driving dynamics tests also conducted on the Nürburgring are ideal for refining the interaction of the all-wheel-drive system with the M sports differential in the rear-axle transmission. With a fully variable locking effect generated by an electric motor, the differential aids the new BMW 2 Series Coupé in optimising cornering performance about traction and driving stability. The targeted distribution of power between the rear wheels enables significantly higher lateral acceleration and also a noticeable increase in dynamics when accelerating as you come out of bends.

Regardless of the engine, all model variants of the new BMW 2 Series Coupé benefit from a particularly torsion-resistant body structure. Static torsional stiffness has been increased by around 12 per cent compared to the predecessor model, for example, through dynamic driving struts in the rear of the vehicle, which contribute to the exceptionally high agility of the new BMW 2 Series Coupé. In addition, the vehicle concept, which is consistently designed for driving dynamics, offers significantly increased track width at the front and rear axles. This effectively reduces body roll and wheel load fluctuations during sporty cornering.

All model variants of the new BMW 2 Series Coupé are also equipped with stroke-dependent dampers as standard. The fine-tuning leads to a noticeably optimised balance between sportiness and ride comfort. They respond sensitively to slight road unevenness and compensate vibrations for optimising comfort. When driving over large bumps, the movements of the body are controlled by correspondingly higher damper forces. An Adaptive M Chassis is offered as an option for the new BMW 2 Series Coupé. Its electronically controlled dampers offer the option of activating the appropriate mapping for both sporty and comfort-oriented driving.

In addition to the balanced axle load distribution between the front and rear wheels, the model-specific design of the steering and the particularly high connection stiffness of the support bearings on the front axle contribute to this. Available as an option for the new BMW 2 Series Coupé, Variable Sports Steering combines further optimised precision when steering into bends with reduced steering effort when parking and manoeuvring.

The body design of the new BMW 2 Series Coupé not only reflects the brand's modern, clear and reduced design language. Only visible at second glance, but immediately noticeable during the high-speed test drives at the Nürburgring. These measures help optimise the aerodynamic properties of the BMW M car in particular. In addition to a model-specific front spoiler lip, front splitter and air curtains, air deflectors, a tank and a rear axle cover as well as the contours of the air-flow-optimised driving dynamics struts on the underbody ensure that lift on the front axle has been reduced by 50 percent compared to the predecessor model.
