The sleek and compact CLA250 is Mercedes' entry-level, front-drive, compact, four-door coupe. It has a nicely-finished cabin and fuel economy of 28 mpg is respectable. But the driving experience falls well short of a typical Mercedes. The 2.0-liter four-cylinder and seven-speed automatic lack refinement. It's quick, but power delivery is uneven. While fairly agile, the car rides stiffly. The cabin is noisy and cramped, especially in the rear, the view out is seriously impaired, and access is difficult both front and rear. Standard features include power front seats with memory, Bluetooth, forward-collision warning and a folding rear seat. The optional blind-spot monitoring system is an easy choice, as is the backup camera. All-wheel drive is also optional. The high-performance, 355-hp CLA45 tops the range. The 2016 models got an upgraded infotainment system with a larger standard screen and media interface capability,as well as standard dual-zone automatic climate control and keyless start.
