All-New V-8-Powered Mercedes-AMG CLE63 Expected by 2026: A V-8 Engine Family Designed with North America in Mind
Take heart, enthusiasts of raw power: A Mercedes-AMG CLE63 equipped with a potent new V-8 engine is in development, and early whispers from internal sources suggest it will be phenomenal. While the German automaker has yet to confirm the official launch timeline for the all-new CLE63 coupe and convertible, sources indicate it is very much a reality, with executives having already driven early prototypes. Although it won’t debut this year, Adam Chamberlain, CEO of Mercedes-Benz USA, has confirmed that the car will be worth the wait, describing it as an unbelievable automotive achievement.
Such a vehicle holds significant strategic importance for Chamberlain and his leadership team. Market projections show that approximately 95 percent of CLE63 sales are expected to occur in North America. Consequently, the new CLE63 is being engineered from the ground up as a purpose-built, American-specification model, meticulously designed to cater specifically to the demands and preferences of the U.S. market.
The New V-8: A Blend of Performance and Efficiency
The heart of the upcoming Mercedes-AMG CLE63 lies in the automaker’s newly developed family of V-8 engines. This engine lineup is engineered to strike a critical balance: maintaining a high-performance character essential for the AMG brand while simultaneously achieving lower emissions to comply with evolving environmental regulations.
This new 4.0-liter twin-turbo V-8, featuring an advanced flat-plane crankshaft, is already positioned at the vanguard of Mercedes’ electrification strategy. It debuted in the recently launched 2027 S-Class and will also power the forthcoming 2027 Mercedes-Benz GLE580 and GLS580 SUVs, both of which recently completed their global premieres. In these vehicles, the engine produces a robust 530 horsepower and 553 lb-ft of torque. Unsurprisingly, Mercedes-AMG has confirmed its intention to tune performance variants of this new V-8, ensuring an even more exhilarating experience for enthusiasts.
Strategic Development and North American Focus
The decision to develop a V-8 engine and place it in the CLE63 reflects a renewed strategic focus on the North American market. According to Chamberlain, V-8-powered cars remain significantly more desirable to U.S. consumers than in many other global regions. In addition to the CLE63, Mercedes-Benz is developing another two or three products specifically for the U.S. market, which will be built on a new platform that is also expected to support a V-8 engine.
This strategic product offensive is part of a massive global initiative by Mercedes-Benz Group and its luxury sub-brands—Mercedes-AMG and Maybach. The company plans to launch 40 new vehicles within a three-year timeframe, offering a diverse powertrain portfolio that includes internal combustion engines, hybrids (including plug-in hybrids), and fully electric vehicles.
Market Dynamics and V-8 Demand
This investment in V-8 technology underscores a clear commitment to the powerplant, as articulated by Mercedes-Benz Group CEO and Chairman of the Board of Management Ola Källenius. More broadly, it signals a dedication to meeting the needs of U.S. customers, where the V-8 has been a staple in high-end and high-performance Mercedes vehicles for decades.
Källenius described the new V-8 as launching in the 2027 S-Class with a focus on delivering quiet but dominant performance; a true “wolf in sheep’s clothing.” However, he emphasized that the AMG version will unleash the full beast, promising a “wolf and an Alpha wolf” configuration. Källenius confidently asserted, “V-8 fans in the U.S. are absolutely going to love that,” indicating that the new CLE63 is poised to exceed even the highest expectations.
Evolution of the 2027 S-Class
The 2027 S-Class receives this V-8 infusion as part of a sweeping refresh that focuses on both technology and performance. The new S-Class features a bold exterior design with reshaped bumpers, grille, and headlights, alongside the new V-8 engine. Inside, the luxury sedan gains updated displays, new trim options, and improved voice control technology, including an enhanced MBUX system. The interior maintains the opulent character Mercedes-Benz is known for, with premium materials, advanced ambient lighting, and a focus on passenger comfort. The S-Class continues to serve as the flagship for the brand, embodying the pinnacle of automotive engineering, technology, and luxury.
The 2027 GLS and GLE SUVs: Global Premieres
The world debuts of the 2027 Mercedes-Benz GLS and GLE SUVs took place at the automaker’s manufacturing facility in Alabama, marking a significant moment for North American production. These models join the S-Class as part of the brand’s commitment to V-8 performance in the U.S. market.
The 2027 GLS features exterior updates including restyled front and rear fascias and new wheel designs. Inside, it offers a significantly improved MBUX infotainment system with an updated interface and enhanced voice control, alongside optional Burmester 4D Surround Sound. The interior design emphasizes luxury and comfort, with high-quality materials and advanced ambient lighting. Safety and driver-assistance systems are also enhanced, offering even greater protection and convenience. The GLS continues to serve as the top-tier SUV in the Mercedes-Benz lineup, providing a blend of luxury, space, and performance.
The 2027 GLE SUV also receives a comprehensive refresh, featuring updated exterior styling with restyled bumpers, grille, and headlights. Inside, it benefits from the latest MBUX infotainment system with an updated interface, new trim options, and enhanced voice control. The GLE continues to be a versatile luxury SUV, offering a compelling package of style, performance, and technology. Both SUVs reinforce Mercedes-Benz’s commitment to the V-8 engine and the U.S. market.
Future of V-8 in High-Performance Sedans
Does this mean we’ll see a V-8 in a future E-Class or C-Class? That remains unconfirmed at this time, according to Chamberlain. Like many enthusiasts, he would welcome an E63 wagon, but the business case is questionable with North America being its primary market. Buyers already have a strong alternative in the E53 wagon, which is powered by a plug-in-hybrid-boosted version of the automaker’s 3.0-liter inline-six, producing 577 horsepower.
A similar version of that six-cylinder engine with 443 horsepower currently powers the most powerful CLE model, the Mercedes-AMG CLE53 (pictured at the top and bottom of the article), although it does not use a plug-in hybrid system like the wagon. It is presumed that any future CLE63 will generate even greater power from an AMG-tuned variant of the new twin-turbo V-8.
Conclusion: A Premium Vehicle Built for the North American Market
The Mercedes-AMG CLE63 stands as a testament to Mercedes-Benz’s renewed focus on the North American market and its commitment to providing V-8 performance to its U.S. customers. With a redesigned V-8 engine and advanced technology, the new CLE63 promises to deliver an exceptional driving experience that will delight enthusiasts of high-performance vehicles. As we look forward to its arrival, one thing is certain: this is a car that V-8 fans in the U.S. will genuinely appreciate, and it is shaping up to be one of the most exciting additions to the Mercedes-AMG lineup in years.
