Mercedes-Benz CLA 45 AMG Racing Series

MB CL 45 AMG Racing Series_frontThe Mercedes-Benz CLA 45 AMG Racing Series concept car provides a preview of a customer sports racing car from Mercedes-AMG. It is based on the Mercedes-Benz CLA 45 AMG, which turbocharged AMG 2.0-litre unit generates 265 kW (360 hp) and maximum torque of 450 newton metres. As on the standard model, power on the racing version is transferred by the AMG Speedshift DCT 7-speed sports transmission. The technical specifications will vary according to the race rules and race series. The engine output and power transmission are variable, with permanent all-wheel drive or purely front-wheel drive possible as in the standard version. Given sufficient demand, the near-series CLA 45 AMG Racing Series could enter various international race series such as national brand-specific trophies or the German VLN series.

Typical racing car features made completely from carbon-fibre (CFRP) make the extravagant design of the standard CLA 45 AMG even more spectacular. They include a new front and rear apron, flared wings and side sill panels. In addition, treadless racing tyres ensure an impressive width. Thanks to carbon-fibre rear wings and large cooling apertures for engine and brake cooling, the CLA 45 AMG Racing Series makes an imposing impression even when stationary. For use on the racetrack, the already good aerodynamic attributes of the four-door high-performance coupé are further optimised by the newly developed carbon-fibre components.

The front apron with a front splitter ensures additional downforce, as do the rear diffuser with three fins and the adjustable rear aerofoil. The air intake in the side sill panels ahead of the rear wheels ensures effective cooling of the rear brakes. Wheel arch vents in the wings, which are flared by over six centimetres on each side, increase the downforce at the front and rear axles. In true racing style, the bonnet and boot lid are fitted with quick-release catches. In short: the motor racing DNA of AMG, the performance brand within Mercedes-Benz, is immediately recognisable in the CLA 45 AMG Racing Series.

A functional racing car atmosphere predominates in the interior. The roll-over cage is made of high-strength steel. An exemplary level of safety is ensured by the carbon-fibre P 1300 GT racing bucket seat from Recaro, prepared for the HANS system, and the integrated fire extinguishing system. In the cockpit the AMG instrument cluster keeps the driver informed about the road speed, engine speed and the operating temperatures of the engine and transmission. The racing steering wheel with shift paddles for gearshifts allows perfect vehicle control. The centre console houses additional controls such as the central switch for the onboard electronics and switches for the hazard warning system and fire extinguishing system.

The special racing suspension has a wider track at the front and rear, and allows numerous adjustments for an individual racetrack setup. The suspension level, spring rate and damper characteristics are adjustable, as are the track and camber at the front and rear axles. The AMG high-performance braking system with ventilated discs all-round is equipped with an anti-lock system. The AMG light-alloy wheels in a cross-spoke design are shod with racing tyres in size 265-660-18 from technical development partner Dunlop, and to reduce unsprung masses the AMG light-alloy wheels feature a particularly lightweight forged construction. The electro-mechanical AMG speed-sensitive sports steering assists with agile handling. Fast wheel-changes during pit-stops are made possible by the pneumatic lifting system integrated into the underbody.
