The biggest four-door coupe from Mercedes-Benz got a refreshed version for the 2010 model, and it brought more luxury to that specific niche market of the premium segment. Mercedes-Benz might not be the first carmaker that built a four-door coupe, but it was the most successful when it introduced it in 2004 and relaunched a segment that was forgotten for decades. In 2010, it unveiled the second generation, which was refreshed in 2014. The most striking feature of the facelifted version was the headlights, with LEDs instead of bi-xenon headlamps. A horizontal satin-silver slat spread across the black grille made the car looks sportier, while the apron with the A-shaped air intake in the middle resembled the SLS AMG. Its LED daytime running lights from the side-scoops looked suspended in over the black mesh-grille behind them. Inside, the carmaker installed a slightly wider interior with more elbow and shoulder room. For the first time, the CLS was fitted with an EASY-PACK quickfold as an option for the rear seat backrest. That allowed longer items to be loaded through the 520 liters (18.3 cu-ft) trunk. Under the hood, Mercedes-Benz installed a choice of four engines, apart from those offered by the AMG department. All versions were fitted as standard with a seven-speed automatic (dual-clutch) transmission. The CLS was available with rear- or all-wheel-drive, depending on the engine.
