The Future of AMG Power: Why the V-8 Isn’t Dying at Mercedes-Benz
For years, performance enthusiasts and industry observers alike have been anticipating the next chapter in the high-performance Mercedes-AMG lineup. Rumors have swirled about the eventual discontinuation of V-8 engines, driven by tightening emissions standards and the industry-wide push toward electrification. However, in a significant development for the North American market, Mercedes-Benz is proving these predictions wrong with a new generation of V-8 powerplants. The company’s commitment to this iconic engine configuration is clearly demonstrated by the ongoing development of the next-generation Mercedes-AMG CLE63.
Mercedes-Benz has not yet officially announced the release date for the upcoming CLE63 coupe and convertible. However, early indicators suggest that the vehicle is firmly in the pipeline, with early prototypes already undergoing testing. While it won’t arrive this year, executives familiar with the project have described the new CLE63 as a truly remarkable machine, and they believe it will be well worth the wait for enthusiasts.
This model is particularly important to Mercedes-Benz USA and its leadership. In fact, 95 percent of CLE63 sales are projected to occur in the North American market. The new CLE63 is being specifically engineered to meet the demands of American consumers, making it a North American-first development.
Beneath the hood of the CLE63 will be one of the automaker’s newly developed V-8 engines. This new engine family is designed to deliver the high-performance characteristics that AMG is known for, while simultaneously achieving lower emissions to comply with future environmental regulations. The 4.0-liter twin-turbo V-8 with a flat-plane crankshaft is already available in the 2027 S-Class and is slated to power the upcoming 2027 Mercedes-Benz GLE580 and GLS580 SUVs. These vehicles recently had their global debuts and feature the engine producing 530 horsepower and 553 lb-ft of torque. Unsurprisingly, AMG has confirmed that it will be tuning performance variants of this new V-8 for its AMG models.
Mercedes-Benz USA Focus: Catering to V-8 Enthusiasts
With the development of the new CLE63, Mercedes-Benz is demonstrating a renewed focus on the North American market, where V-8-powered cars remain significantly more popular than in other regions. Adam Chamberlain, the CEO of Mercedes-Benz USA, indicated that the company is working on an additional two or three products specifically designed for North America. These vehicles are being developed on a new platform that will also support a V-8 engine, further emphasizing the manufacturer’s commitment to this powertrain in the region.
This initiative is part of a massive global product offensive involving 40 new vehicles over the next three years, spanning Mercedes-Benz, Mercedes-AMG, and Maybach. These vehicles will include internal combustion engines, hybrids (including plug-in hybrids), and fully electric vehicles.
Why V-8s Remain Crucial for Mercedes-AMG
Investing in V-8s represents a strong commitment to the engine configuration by Ola Källenius, the Chairman of the Board of Management and CEO of Mercedes-Benz Group. More broadly, it signifies a dedication to meeting the needs of U.S. customers, where V-8s have been a staple in high-end and high-performance Mercedes vehicles for decades.
The new V-8 is being introduced in the 2027 S-Class, offering refined yet dominant performance. Källenius described the standard S-Class V-8 as “the wolf in sheep’s clothing.” He further elaborated, “But then the wolf really comes out with the AMG version, so there will be a wolf and an Alpha wolf coming. V-8 fans in the U.S. are absolutely going to love that.” Based on current information, fans of the 4.0-liter twin-turbo V-8 are poised to be thrilled with the powertrain coming to the new CLE63.
This strategy highlights a clear distinction between the global product roadmap and the specific needs of the American market. While Mercedes-Benz globally transitions toward battery-electric vehicles, they recognize that the North American demand for high-performance, internal combustion engines remains strong. The introduction of the V-8 in the S-Class and its subsequent adaptation for AMG models reflects this market-specific approach.
The Transition to the 4.0-Liter Twin-Turbo V-8
The 4.0-liter twin-turbo V-8 engine has been a cornerstone of the Mercedes-AMG lineup for the better part of a decade. While the engine has undergone continuous refinement to improve efficiency and reduce emissions, the upcoming introduction of a flat-plane crankshaft version marks a significant shift in its character. This new variant is expected to deliver a racier sound and increased responsiveness, aligning more closely with the needs of performance-oriented drivers.
For fans of traditional V-8 power and sound, the flat-plane crankshaft technology is particularly exciting. This design change allows for better exhaust scavenging and a higher-revving engine, producing a distinct, aggressive exhaust note that differs from the typical cross-plane crankshaft V-8s. The integration of this technology in the new generation of Mercedes-AMG CLE63 ensures that the model will maintain its sonic character while meeting modern emissions standards.
Performance Parallels: CLE53 and CLE63
Currently, the most powerful Mercedes-AMG CLE model available is the CLE53, which utilizes a 3.0-liter inline-six engine with a mild-hybrid system. This engine produces 443 horsepower, making it a capable performance vehicle in its own right.
The CLE53’s inline-six engine is a 443-horsepower iteration of the same six-cylinder engine used in the E63 wagon, though without the plug-in hybrid system. The CLE63 is expected to generate more power from an AMG-tuned version of the new twin-turbo V-8, ensuring a clear performance hierarchy within the Mercedes-AMG lineup. This distinction ensures that buyers seeking the ultimate performance experience will be drawn to the CLE63, while the CLE53 continues to offer a compelling balance of performance and everyday usability.
This tiered approach reflects a successful strategy for AMG: provide distinct performance levels that cater to different buyer preferences while maintaining brand consistency and AMG DNA across the range. The Mercedes-AMG CLE lineup provides enthusiasts with a clear choice between the agile performance of the inline-six and the raw power of the V-8.
What About the E63 Wagon?
Like many enthusiasts, Adam Chamberlain would love to see an E63 wagon return. However, the business case for such a vehicle is questionable, especially since its primary market would be North America. Furthermore, buyers already have a strong option in the E53 wagon, which is powered by a plug-in hybrid-boosted version of the automaker’s 3.0-liter inline-six engine producing 577 horsepower.
The E63 wagon, a beloved model for years, has been put on hiatus due to shifting market priorities and emissions regulations. Its return remains unconfirmed, though the enthusiasm from Mercedes-Benz’s leadership suggests it’s not entirely off the table. The focus on V-8 development, however, suggests that the company is prioritizing the CLE63 and other V-8-powered models for its North American strategy.
North American Market-Specific Products
The development of the CLE63 is a clear indication of Mercedes’ renewed focus on the North American market, where V-8-powered cars remain far more desirable than in other markets. Chamberlain has noted that an additional two or three Mercedes-Benz products are in the works that are being developed specifically for North America. These vehicles will be built on a new platform that will also support a V-8 engine, further underscoring the company’s commitment to this powertrain in the region.
This strategic alignment of product development with market demand is crucial for success in the competitive luxury automotive sector. By introducing V-8-powered vehicles like the CLE63, Mercedes-Benz can cater to the specific preferences of its American customer base while navigating the complexities of global emissions standards.
The Global Product Offensive
These North American-specific products are part of a larger global product offensive involving 40 new vehicles over the next three years, spanning Mercedes-Benz, Mercedes-AMG, and Maybach. These vehicles will include internal combustion engines, hybrids (including plug-in hybrids), and fully electric vehicles. This comprehensive approach ensures that the brand remains competitive across all market segments and powertrain preferences.
Commitment to V-8 Power in the U.S.
The investment in V-8s shows a real commitment to the powerplant, said Mercedes-Benz Group CEO and Chairman of the Board of Management Ola Källenius. More broadly, it shows a commitment to meeting the needs of its U.S. customers, where the V-8 has been a staple in high-end and high-performance Mercedes vehicles for decades.
Källenius has spoken extensively about the importance of V-8 engines for American consumers. He has emphasized that the V-8 for the more discerning Mercedes owner is launching in the new S-Class, providing quiet but dominant performance.
In summary, the Mercedes-AMG CLE63 is shaping up to be a compelling performance vehicle that combines the iconic character of a V-8 engine with modern efficiency and technology. It is
