From the Mercedes-Benz Facebook page (and everywhere else on the internet!): Presenting the all-new 2015 GLA45 AMG, the fourth high-performance SUV to arrive from our speed shop in Affalterbach. Under the hood is a handcrafted 2.0-liter turbocharged four-cylinder putting down 355-hp and 332 lb-ft of torque through a high-performance 4MATIC all-wheel drive system. It’s an SUV that gets from 0-60 mph in a scant 4.8 seconds-and one that very few others should trifle with. On sale this fall.
