The Mercedes-Benz GLA is the crossover version of the company's A-Class in much the same way as the Subaru XV is a jumped-up Impreza.
The differences are that the German hatch has unique styling and a slightly larger (but still small) rear-seat and cargo capacity, as well as the usual 'lifestyle' add-ons like extra plastic cladding and more ground clearance.
Otherwise, the X156 original of 2013 is pure A-Class, meaning lusty turbo four-cylinder transverse engines and front- or all-wheel drive configurations, sharp handling, a firm-to-hard ride and attractive but cheap-feeling interiors. The second-gen H247 of 2020 is usefully bigger and smoother, bringing in higher-tech features and more attractive cabins. The cheapest grade starts from $60,688, rising to $115,294 for the most expensive version.
Note that cheaper versions like the GLA200 gain a frugal but uncouth three-cylinder turbo petrol engine. The AMG grades at the other end of the GLA range are stunningly fast, and with high pricing to match.
