Mercedes-Benz AMG CLE 53 Unveiled: The Heartbeat of AMG Innovation
Mercedes-Benz has officially raised the bar in the sports coupe segment with the debut of the AMG CLE 53. This 2025 model packs an all-new engine and state-of-the-art mild hybrid powertrain, designed to deliver dynamic performance, everyday usability, and a modern twist on AMG’s performance legacy. Boasting a turbocharged inline-six under the hood, the CLE 53 targets enthusiasts demanding both exhilarating acceleration and future-forward efficiency.
AMG CLE 53 Engine: Inline-Six Turbo With Mild Hybrid Brilliance
The centerpiece of the Mercedes-Benz AMG CLE 53 is its 3.0-liter inline-six engine, internally designated as the M256. This advanced powerplant features twin forced induction: a traditional exhaust-driven turbocharger, complemented by an electric auxiliary compressor. Together, they virtually eliminate turbo lag and deliver muscle across the rev band, resulting in a seamless and responsive drive experience.

This new AMG engine not only offers higher peak torque and sharper throttle response but also delivers improved efficiency and reduced emissions, thanks to the integrated 48-volt mild-hybrid architecture and the electric auxiliary compressor’s extended operating window.
Real-World Performance: Acceleration, Handling, and Efficiency
Performance figures for the CLE 53 firmly plant it among the best of its class. The coupe sprints from 0–100km/h in a blistering 4.2 seconds (manufacturer claim), with the Cabriolet only tenth slower. Top speed is electronically limited to 250km/h.
-
Acceleration (0–100km/h): 4.2 seconds
-
Top Speed: 250km/h (155mph)
-
Fuel Economy: 20mpg city / 27mpg highway (EPA estimate), with European WLTP consumption as low as 9.4L/100km
-
Curb Weight: 2,000kg
The AMG CLE 53’s mild hybrid system plays a crucial role—delivering low-end torque fill for instant acceleration and smoothing out start-stop transitions. The 9-speed transmission’s rapid shifts adapt to mood with Sport, Comfort, and Sport+ modes, while AMG-tuned all-wheel drive ensures traction even under full throttle.
On the road, the CLE 53’s adaptive suspension and steering calibration are notably sportier than the standard CLE models, promoting cornering stability and direct, communicative feedback. AMG’s upgraded braking system provides enhanced stopping power, aligning braking feel with its performance potential.
How the CLE 53 Engine Compares: Past and Present AMG Legacy
The move to a straight-six hybrid marks a significant evolution from the outgoing V6 used in previous AMG “53” models. Compared to its predecessor, the new powertrain delivers more horsepower, improved torque spread, and notably quicker real-world acceleration, thanks to the electrification boost.

Previous Gen AMG “53” Models: Used a 3.0L twin-turbo I6, but the CLE 53’s electric compressor and next-gen hybrid system further reduce response lag and enhance efficiency
-
Rival Coupes: The CLE 53 outpaces the BMW M440i (374hp, 0–100km/h in 4.5s) and Audi S5 (354hp, 0–100km/h in 4.7s), cementing its spot at the top of its segment for both headline stats and real-world drivability
Optionally, buyers can select AMG’s Dynamic Package Plus, which increases maximum torque to 600Nm and shaves tenths off its acceleration performance, pushing the car deeper into properly sporty territory.
The Verdict: The New AMG Benchmark Under the Hood
The 2025 Mercedes-Benz AMG CLE 53 exemplifies the brand’s commitment to blending cutting-edge technology with authentic AMG sportsmanship. Its twin-charged, hybrid-assisted inline-six positions it as a technological showcase—at once powerful, efficient, and intoxicating to drive.
AMG fans will appreciate the smooth, high-revving character of the straight-six and the electric torque punch, while traditionalists will find familiar AMG cues in its soundtrack and throttle response. With class-leading acceleration and a next-generation powertrain, the CLE 53 sets the new benchmark for performance hybrids in the premium coupe market.
