From Mild Hybrid to AMG: Inside the New Mercedes CLE Powertrains
November 19 2024,
The 2024 Mercedes-Benz CLE Coupe introduces Mercedes-Benz's most advanced powertrain technology to date. From the precisely tuned mild hybrid system of the CLE 300 4MATIC to the high-output AMG CLE 53, each variant demonstrates measurable performance gains through electrification. This comprehensive approach to powertrain development sets new benchmarks for response, efficiency, and driver engagement in the luxury segment.
Mild Hybrid Technology: Power Meets Precision
At the heart of the standard CLE 300 4MATIC lies an innovative mild hybrid system that delivers immediate power increases. The second-generation integrated starter generator contributes an additional 23 horsepower and 148 lb-ft of torque, supplementing the base 255 horsepower from the 2.0-litre turbocharged four-cylinder engine. This electrified powertrain operates through a sophisticated 48-volt electrical system, providing instantaneous throttle response and smoother power delivery. The system's electronic management eliminates the traditional delay between driver input and engine response, particularly noticeable during urban driving conditions.
Advanced Transmission Integration
Mercedes-Benz engineers have redeveloped the 9G-TRONIC transmission specifically for hybrid applications. The nine-speed automatic now incorporates the electric motor, power electronics, and transmission cooler directly into its housing. This structural integration reduces overall weight by 30 percent compared to previous designs. The transmission's new multi-core processor enables precise gear selection and power delivery, while optimized oil flow reduces mechanical losses. These improvements result in both faster acceleration and reduced fuel consumption across all driving conditions.
AMG Performance: Electrified Precision
The AMG CLE 53 4MATIC+ demonstrates the performance potential of hybrid technology. Its AMG-enhanced 3.0-litre inline-six engine generates 443 horsepower and 413 lb-ft of torque, with an overboost function providing up to 443 lb-ft during intense acceleration. The combination of an exhaust gas turbocharger and electric auxiliary compressor provides immediate throttle response, while the integrated starter generator contributes an additional 23 horsepower and 151 lb-ft of electric assistance. This sophisticated powertrain enables the AMG variant to deliver consistent power across its entire rpm range.
Performance Metrics and Real-World Application
The standard CLE 300 4MATIC accelerates from 0-100 km/h in 6.3 seconds, while maintaining fuel efficiency through its hybrid system. The 48-volt architecture enables extended engine-off coasting, seamless stop-start operation, and energy recuperation during braking. The AMG variant builds on these capabilities with specialized tuning that prioritizes performance, including a variable all-wheel-drive system that can send more power to the rear wheels for dynamic handling.
Technological Integration
Both powertrains benefit from Mercedes-Benz's latest electronic architecture. The system manages power distribution between the combustion engine and electric motor, optimizing output based on driving conditions and driver inputs. This integration extends to the transmission control unit, which uses predictive data to prepare for power demands before they occur. The result is responsive acceleration without sacrificing smoothness or efficiency.
Availability?
Mercedes-Benz has tailored the CLE lineup specifically for Canadian driving conditions. The CLE 300 4MATIC, starting at $66,735, comes standard with all-wheel drive and cold-weather features. The AMG CLE 53 arrives very soon, bringing additional performance capabilities to the Canadian market. Both variants showcase how electrification technology enhances performance across all driving conditions.
The CLE Coupe's powertrain development characterizes Mercedes-Benz's promise of performance innovation. Each component - from the integrated starter generator to the transmission control software - contributes to a driving experience that delivers both immediate response and long-term efficiency. These advancements provide tangible benefits for Canadian drivers seeking performance without compromise.
