The 2015 Mercedes-Benz GLA250 is powered by a turbocharged 2.0-liter four-cylinder with 208 hp and 258 pound-feet of torque matched to a seven-speed automated manual transmission (with shift paddles). Initially, just the all-wheel-drive (4Matic) version will be available, with the front-drive version to follow. Mercedes says the all-wheel-drive GLA will accelerate from zero to 60 mph in 7.1 seconds. Both the GLA250 and the GLA 45 AMG feature an automatic stop-start function that, if engaged, turns off the engine when the car stops to save fuel.The powerhouse GLA 45 AMG coaxes a very impressive 355 hp and 332 lb-ft of torque from the same 2.0-liter engine. A quicker-shifting version of the seven-speed transmission sends the power to all four wheels. The GLA 45 AMG also features a three-mode stability-control system (that allows drivers to tailor the level of intervention) and launch control. Mercedes says the GLA 45 can rocket from zero to 60 mph in 4.8 seconds.
EPA-estimated fuel economy for the GLA-Class is quite good: GLA250 4Matic earns 27 mpg combined(24 city/32 highway) while the GLA 45 AMG’s economy comes in at 25 mpg combined (23/29).
The 2015 Mercedes-Benz GLA-Class comes standard with stability and traction control, antilock brakes, a driver knee airbag, front seat side thorax airbags, front seat side pelvic airbags and full-length side curtain airbags.
