Unveiled in 2013, the Mercedes-Benz GLA is the company’s smallest crossover yet and shares underpinnings with the A-Class hatchback. Much like al Mercedes-Benz vehicles, it received its very own AMG version. Previewed by a concept car in 2013, the production model arrived in 2014 with the same engine as the awesome Mercedes A45 AMG hatch. The GLA45 joined a new niche in the compact luxury market, introduced by Audi with the RS Q3 a year before. As of 2017, the much rumored M version of the BMW X1 has yet to arrive, leaving only Mercedes-Benz and Audi to battle for supremacy in this segment.
