The GLA, Mercedes-Benz' luxury compact crossover, is built on the capable chassis found under the CLA sedan and utilizes its powerplant lineup, consisting of either a 208-horsepower turbocharged 2.0L 4-cylinder or, in the GLA45, the same engine tuned to make 375 horsepower. The engine comes mated to a dual-clutch 7-speed automatic transmission with steering wheel-mounted paddle shifters, and power is delivered to all four wheels. Three driving modes include Sport, Manual and ECO, which offers idle engine shut-off when the vehicle is stopped. Mercedes claims the GLA250 can scoot to 60 mph in around seven seconds. The GLA45 can make 60 mph in an astonishing 4.8 seconds. Both GLA models use the latest generation of 4MATIC all-wheel drive, and the variable-torque system monitors each corner of the vehicle, sending up to 50 percent of the engine's torque to the rear wheels. The system also adapts to varying unpaved travel with an off-road mode. The GLA250 comes well equipped with 18-inch wheels, rain-sensing windshield wipers, a choice of MB-Tex interior surfaces as well as ambient interior lighting, HD radio with Bluetooth hands-free connectivity and audio streaming, a 14-way power driver seat with memory, split-folding rear seats and a power liftgate. Several stand-alone options allow buyers to fully customize the GLA, including a panorama roof, bi-xenon headlights and LED taillights, heated front seats, a harman/kardon sound system, rearview camera, Parktronic parking assist and blind-spot assist. Meanwhile a Sport Package adds special exterior body styling, 19-inch AMG wheels and perforated front brakes with painted calipers. The Interior Package adds leather upholstery, sport seats and remote window opening/closing, while the Premium Package provides dual-zone automatic climate control, heated front seats, the harman/kardon stereo and more. Finally, the Multimedia Package adds a rearview camera, advanced voice control, an 80GB hard-drive navigation system and in-dash SD card reader. The GLA45 AMG is all about performance and its features and accessories all speak to that, including AMG sport suspension and sport exhaust. It also features available AMG performance seats and steering wheel, red-painted rear calipers, an aerodynamic package and rear deck lid spoiler.
