2021 Mercedes-Benz GLA: What's New, Specs & Features
Last updated August 4, 2026
The 2021 Mercedes-Benz GLA is fully redesigned, marking the start of its second generation. The biggest change is its roomier, more upright SUV shape, backed by a stronger engine and a much more modern cabin.
About the 2021 Mercedes-Benz GLA
2nd generation (H247), first U.S. model year after a full redesign.
The GLA is Mercedes-Benz’s smallest SUV, aimed at shoppers who want the brand’s look, cabin feel, and technology in a city-friendly size. Mercedes positions it as a compact luxury SUV that blends a higher seating position, flexible cargo space, and quick turbo power with an easy-to-use touchscreen and voice-control interface. Against rivals, the GLA leans more toward upscale design, rich in-cabin presentation, and everyday maneuverability than maximum cargo room.
The GLA 250 is the everyday, city-friendly version, with front-wheel drive, a 221-hp turbo engine, dual 7-inch displays, Apple CarPlay, Android Auto, and a power liftgate. The GLA 250 4MATIC adds all-wheel drive, an off-road driving mode, and downhill speed control for extra traction on snow or loose surfaces. Both have power front seats, automatic emergency braking, and blind-spot monitoring.
What changed, by category
Powertrain
The GLA 250 and GLA 250 4MATIC receive a stronger 221-hp turbocharged 2.0-liter four-cylinder, up from 208 hp, plus an 8-speed dual-clutch automatic transmission.
Styling
The redesigned body is taller and more upright, giving the GLA a more conventional small-SUV shape. LED headlights are standard rather than optional.
Safety
Blind-spot monitoring becomes standard across the lineup. It includes an exit warning that can alert occupants to traffic approaching from behind before a door is opened.
Tech
A new twin-screen dashboard brings dual 7-inch displays, touchscreen controls, the “Hey Mercedes” voice assistant, Apple CarPlay, Android Auto, and four USB-C ports. Navigation and satellite radio move from standard to optional equipment.
Structural
A new platform and longer wheelbase create more passenger and cargo room. Rear legroom grows from 33.9 to 38 inches, while maximum cargo capacity rises from 43.6 to 59.5 cubic feet.
