2021 Mercedes-Benz CLA: What's New, Specs & Features
Last updated August 4, 2026
The most important change for the 2021 Mercedes-Benz CLA is that Blind Spot Assist with Exit Warning Assist becomes standard across the lineup. It is otherwise a light equipment update, with no redesign or powertrain change.
About the 2021 Mercedes-Benz CLA
2nd generation (C118), second model year after the 2020 redesign.
Mercedes-Benz positions the CLA as a style-first compact luxury four-door coupe with a dramatic roofline, a flashy digital cabin, and a more premium feel than its size suggests. It is meant for buyers who want Mercedes design and cabin tech in a smaller footprint than a C-Class. Against rivals like the Audi A3 and BMW 2 Series Gran Coupe, the CLA leans hardest into coupe-like styling and a showpiece interior.
The CLA 250 is the style-focused entry model, pairing a 221-hp turbocharged four-cylinder engine with front-wheel drive, a panoramic glass roof, and a digital cabin. The CLA 250 4MATIC keeps the same engine and features but adds all-wheel drive for extra traction. Both have a touchscreen system with Apple CarPlay and Android Auto, power front sport seats, and 64-color ambient lighting.
