The core of the new BMW M2 CS 2021 (the most thrusting version of the M2 range) is its new engine, based on the power unit of the BMW M3 and BMW M4. The straight-six generates a maximum power of 450 hp at 6,250 Rpm, 29 kW (40 hp) more than the BMW M2 Competition. Maximum torque of 550 Newton meters is available between 2,350 and 5,500 Rpm. But before going further, I invite you to take a look at the complete list of the BMW M2 CS 2021
Aesthetically, the distinctive elements are the attractive central air intake in glossy black on the bonnet in lightweight CFRP (Carbon Fiber Reinforced Plastics). This adds to the roof which is also made entirely of carbon fiber. The new front splitter and a rear diffuser are also in carbon. Other special features of the BMW M2 CS are equipped with 19-inch forged wheels in glossy black or matte gold finish and an enlarged front air intake.
BMW M2 CS 2021: Weight And Its Distribution
The weight remains unchanged compared to the BMW M2 Competition since the increase in power compared to the latter (+40 HP) and the installation of new components required an increase in weight, however, counterbalanced by the carbon components we have just listed. . Furthermore, it should not be forgotten that not only the weight but also its distribution is fundamental on a car.
Having installed a roof and bonnet in light material allows the center of gravity to be lowered, guaranteeing more effective dynamics. The new BMW M2 CS extends a family lineage established by the BMW M3 CS and BMW M4 CS. It has been designed to provide allowance exhilarating performance on the track, without losing the possibility of use in daily road use.
Engine power is transferred to the road or track by the adaptive M suspension, previously the preserve of the M4 models, and the Cup tires. The adaptive M suspension allows the driver to change shock settings through Comfort, Sport and Sport +.
The Driver Sews It On Himself
While the Comfort mode optimizes ride comfort in everyday use in the city, the Sport mode ensures superior dynamic qualities on open roads. Sport +, the most extreme mode, minimizes car body movements and maximizes dynamic behavior for maximum performance on the track.
The brake discs are larger than those of the BMW M2 Competition (front axle: 400 mm diameter, rear axle: 380 mm diameter) as are the calipers (front axle: six-piston fixed calipers, rear axle: four-piston fixed calipers ). This system offers exceptional braking performance with excellent braking power in all conditions, great resistance to fading, and remarkable thermal stability. Customers can also select the carbon-ceramic brake option, BMW M Carbon, with six-piston calipers at the front and four-piston calipers at the rear. These are even lighter and can withstand lasting stress on the track as well as have a longer life.
The BMW M2 CS 2021 is equipped with 19-inch forged wheels in glossy black or, optionally, with a matte gold finish. The front 19-inch wheels weigh only nine kilograms, the rear 19-inch wheels stop the scales at 10 kilos. Thanks to the original equipment Michelin Pilot Sport Cup 2 tires in size 245/35 ZR 19 and rear tires in size 265/35 ZR 19 optimize traction.
High-Level Engine Technology
BMW M TwinPower Turbo technology consists of two fast-response MonoScroll turbochargers, high-precision injection, VALVETRONIC for valve control, and variable Double-VANOS camshaft timing. The valve and camshaft timing work in tandem for maximum variability in intake control as the valve rises. The result is precise responses and optimal power delivery.
When equipped with the seven-speed M double-clutch transmission (optional) it sprints from 0 to 100 km / h in 4.0 seconds. With the six-speed manual gearbox, offered for the first time in a BMW CS, in line with the wishes of target customers with the BMW M2, the acceleration figure is 4.2 seconds. Top speed with the M Driver package is electronically limited to 280 km.
Solutions Designed For Motorsport
The effectively designed oil supply system for the engine is taken directly from BMW’s experience in motorsport. The cooling system of the BMW M4 with Competition Pack is used on the M2 Competition with some modifications. A larger double kidney and a new front bumper design with increased airflow are external signs that indicate the use of this improved cooling system.
The engine compartment hides the most striking component: the CFRP (Carbon Fiber Reinforced Plastics, aesthetic and stiffening element of the engine compartment) frame taken from the BMW M3 / M4. This component is made of extremely light, yet high-strength carbon fiber and weighs only 1.5 kg. This and other elements of the M4 have the function of increasing the stiffness of the front section to improve steering behavior and precision.
The high-performance chassis is fitted with lightweight aluminum elements on the front and rear axles of the BMW M3 / M4. In order to guarantee an extremely precise wheel position, to which spherical wheels are added without play to transmit the transverse forces. Translated: exceptional driving precision thanks in part to the new five-link rear axle in forged aluminum.
The Steering Also Designed For Fast Driving
The BMW M engineers have adapted the characteristic curves of the electromechanical power steering to improve performance and increase the stiffness of the front section. The integrated M-specification Servotronic function electronically controls the level of steering assistance based on the speed of the car and the settings selected with the Drivelogic.
BMW M2 CS 2021: Electronics Give You a Hand!
Support is provided by Active M Differential, an electronically controlled multi-disc limited-slip differential. The locking effect can be varied between 0 and 100 percent, depending on the driving situation, and reacts to the car’s steering angle and some other parameters.
M Dynamic Mode (MDM) is a sub-function of the Dynamic Stability Control (DSC) which can be activated automatically in SPORT + mode or can be activated manually. Certain situations – eg. sporty and dynamic driving on the track – allow a greater degree of wheel rotation. The familiar stabilizing measures from DSC mode now intervene later, increasing the freedom available to drivers by approaching the dynamic limit.
