The 2017 Mercedes-Benz GLA250 is powered by a turbocharged 2.0-liter four-cylinder with 208 hp and 258 lb-ft of torque matched to a seven-speed, dual-clutch automatic transmission (with steering wheel-mounted shift paddles). In Edmunds track testing, the GLA250 4Matic outdid Mercedes' estimated 0-60 time of 7.1 seconds by hitting the milestone in 6.8 seconds, a good showing for this segment.

The AMG GLA 45 pumps out an outstanding 375 hp and 350 lb-ft from the same 2.0-liter engine. A quicker-shifting version of the seven-speed transmission sends power to all four wheels. The AMG GLA 45 also features a three-mode stability control system that allows drivers to tailor the level of intervention and offers available launch control. Mercedes says the GLA 45 can rocket from zero to 60 mph in 4.3 seconds.

Both the GLA250 and the AMG GLA 45 feature an automatic stop-start function that, if engaged, turns off the engine when the car stops to save fuel. Fuel economy figures are quite good: the front-wheel-drive GLA250 achieves 27 mpg combined (24 city/33 highway), while the GLA250 4Matic earns 26 mpg combined (23 city/31 highway). The high-octane AMG GLA 45 isn’t much worse at  25 mpg combined (22 city/28 highway).
