Mercedes has unveiled the CLA 45 AMG Racing Series concept at the Frankfurt Motor Show.

Designed to preview the company's entry-level customer racing car, the CLA 45 AMG RS has a new front bumper with larger air intakes and a carbon fiber splitter. Moving further back, there's extended wheel arches, revised side skirts and an aggressive rear bumper with a carbon fiber diffuser. Other notable highlights include an adjustable rear wing and lightweight alloy wheels with Dunlop racing slicks.

As part of the transformation, engineers installed a race-oriented suspension that has a wider track and adjustable springs and dampers. The model has also been equipped with high-performance brakes and a race-spec interior with a roll cage, a fire extinguishing system and a carbon fiber Recaro racing seat.

Mercedes was coy on technical specifications but confirmed the concept uses the familiar turbocharged 2.0-liter four-cylinder engine that is found in the standard model. Since regulations vary by race and series, the production model will have a variable engine output. The company also floated the possibility of offering the car with front-wheel drive instead of all-wheel drive.
