The Mercedes-Benz CLA-Class is a sporty sedan with sleek styling and seating for up to five. Powered by a choice of 2-liter 4-cylinder turbo engines that optionally drive all wheels through a 7-speed dual-clutch transmission, especially the higher-powered CLA45 AMG handles and performs well thanks to a sports-tuned suspension and 375 hp. Well-built inside, interior-space is confined as a result of the low roofline, however.
