Design Philosophy: Where SUV Meets Coupe Elegance
The 2021 GLE53 Coupe represents Mercedes-AMG's refined approach to the coupe-SUV segment. While sharing the front-end style with its conventional GLE sibling, the Coupe version features:
- A 2.4-inch shorter wheelbase for more dynamic proportions
- More aggressively sloped fastback roofline than previous generation
- Redesigned rear end with smoother, more integrated styling
- Subtle AMG styling cues (more aggressive versions expected later)
Notably, the U.S. market receives only AMG-badged versions of the GLE Coupe, distinguishing it from other markets that offer non-AMG variants.

Powertrain Innovation: The Heart of the GLE53 Coupe
At the core of the 2021 GLE53 Coupe lies Mercedes-AMG's advanced M256 3.0-liter turbocharged inline-six engine, paired with a sophisticated 48-volt mild-hybrid system. This powertrain technology, first seen in AMG 53 versions of the E-Class and CLS, delivers:
Component | Specification |
---|---|
Engine | 3.0L turbocharged inline-6 with electric auxiliary compressor |
Total System Output | 429 hp @ 6,100 rpm / 384 lb-ft @ 1,800-5,800 rpm |
EQ Boost | +21 hp and 184 lb-ft for short bursts |
Transmission | AMG SPEEDSHIFT TCT 9-speed automatic |
Drivetrain | AMG Performance 4MATIC+ all-wheel drive |

EQ Boost Technology Explained
The integrated starter-generator (ISG) serves multiple functions in the GLE53 Coupe's mild-hybrid system:
- Provides torque fill during gear changes for seamless acceleration
- Enables energy recuperation during braking
- Powers the electric auxiliary compressor for reduced turbo lag
- Allows for near-instantaneous engine restarts in stop/start situations

The 2021 GLE53 Coupe delivers sports car-like performance in an SUV package:
Standard AMG-tuned chassis components include:
- AMG-specific axle kinematics for sharper turn-in
- Speed-sensitive power steering with AMG tuning
- AMG DYNAMIC SELECT driving modes (Slippery, Comfort, Sport, Sport+, Individual)

Interior Luxury and Technology
The GLE53 Coupe's cabin blends AMG's performance focus with Mercedes-Benz's renowned luxury:
Interior Highlights
- AMG-specific digital instrument cluster (12.3-inch)
- MBUX infotainment system with augmented reality navigation
- AMG performance steering wheel with aluminum shift paddles
- Optional AMG Nappa leather performance seats
- Energizing comfort control with multiple climate programs
Despite the sloping roofline, Mercedes engineers have maintained impressive rear headroom through careful interior packaging. Cargo capacity stands at 17.6 cubic feet behind the rear seats, expanding to 60.7 cubic feet with the seats folded.
