Third Generation of the CLS-Class The C257 CLS, introduced in 2018, is the third-generation CLS-Class, continuing Mercedes’ trend of blending coupe styling with four-door practicality.
First CLS Without a V8 Engine Unlike previous generations, the C257 CLS does not offer a V8 engine, as Mercedes focused on efficiency and hybrid-assisted powertrains.
Sleek and Aerodynamic Design The C257 has a drag coefficient of just 0.26, making it one of the most aerodynamic four-door coupes on the market, enhancing efficiency and stability.
New Inline-Six Engine for the CLS 53 AMG The CLS 53 AMG introduced Mercedes’ new 3.0L turbocharged inline-six engine with EQ Boost (mild-hybrid technology), producing 429 hp and 520 Nm of torque.
Exclusive Three-Seat Rear Configuration Unlike previous CLS models, which had two individual rear seats, the C257 offers a three-seat rear bench, increasing practicality.
Advanced MBUX Infotainment System The C257 comes equipped with Mercedes’ MBUX infotainment system, featuring voice control, AI-based learning, and a fully digital driver display.
CLS 450 Features Mild-Hybrid Technology The CLS 450 comes with a 3.0L turbocharged inline-six with a 48V mild-hybrid system, improving fuel efficiency and providing an extra 21 hp boost when needed.
AMG GT-Inspired Interior The C257’s interior design takes inspiration from the Mercedes-AMG GT, featuring turbine-style air vents, high-quality leather, and customizable ambient lighting.
Available with Mercedes 4MATIC+ AWD System Most CLS models, including the CLS 450 and CLS 53 AMG, come with Mercedes’ 4MATIC+ all-wheel-drive system, improving traction and handling.
Discontinued in 2023 Mercedes-Benz ended CLS production in 2023, marking the end of the CLS lineup as the company shifts focus to EVs and the CLE-Class.

The C257 CLS is Merc’s sleek four-door coupe—now with mild-hybrid tech, AMG-enhanced powertrains, and EQ Boost electrification. A tech-heavy grand tourer that depreciates sharply but offers big value used.
