The new Mercedes-AMG CLE63 V8 is the engine most fans have been hoping for. While details are still under wraps, insiders say it’s a masterpiece that will set a new standard for performance coupes in the U.S.
Mercedes-Benz has not officially confirmed the release date of the upcoming CLE63 coupe and convertible, but the car is real. Early prototypes have been driven by executives, and according to Adam Chamberlain, CEO of Mercedes-Benz USA, it will be worth the wait and is expected to be phenomenal.
A vehicle like this is crucial for Chamberlain and his team because 95% of CLE63 sales are expected to be in North America. The new CLE63 is specifically designed for the American market.
For the V8 engine, Mercedes-Benz has developed a new family that retains high performance while reducing emissions to meet future regulations. The new 4.0-liter twin-turbo V8 with a flat-plane crankshaft is already in the 2027 S-Class and will power the upcoming 2027 GLE580 and GLS580 SUVs. In these vehicles, the engine produces 530 hp and 553 lb-ft of torque. AMG has also confirmed it will tune performance variants of this V8.
Whether this means a V8 will appear in a future high-performance E-Class or C-Class is unconfirmed. Many enthusiasts, like Chamberlain, would love an E63 wagon, but the business case is uncertain with North America as its only primary market. Buyers already have a strong option in the E53 wagon, which uses a plug-in hybrid-boosted 3.0-liter inline-six with 577 hp.
A similar six-cylinder engine with 443 hp is under the hood of the most powerful CLE currently, the Mercedes-AMG CLE53 (pictured top and bottom), although it lacks the plug-in hybrid system of the wagon. It’s likely that any CLE63 will generate more power from an AMG-tuned version of the new twin-turbo V8.
The recent world debuts of the 2027 Mercedes-Benz GLS and GLE SUVs took place at the automaker’s Alabama factory.
Renewed North American Focus
The CLE63 reflects Mercedes’ renewed focus on North America, where V8 cars remain much more popular than elsewhere. Another two or three products are expected to be developed specifically for North America, built on a new platform that could also support a V8.
This is part of a massive global product offensive: 40 vehicles in three years for Mercedes-Benz and its Mercedes-AMG and Maybach offshoots, offering internal combustion engines, hybrids (including plug-in hybrids), and fully electric vehicles.

Committed to V8s for the U.S.
Investing in V8 technology 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 U.S. customers, where the V8 has been a staple in high-end and high-performance Mercedes vehicles for decades.
The V8 for discerning Mercedes owners is launching in the new S-Class, providing quiet but dominant performance. It’s still a beast but more refined. “That is the wolf in sheep’s clothing,” Källenius told MotorTrend. “But then the wolf really comes out with the AMG version, so there will be a wolf and an Alpha wolf coming,” he said. “V8 fans in the U.S. are absolutely going to love that.” Based on what we know now, they’re going to love what’s coming under the hood of the new CLE63.

Introduction
The automotive industry is undergoing a massive transformation, with electrification dominating the headlines. However, for many enthusiasts, the allure of a powerful, naturally aspirated engine remains strong. Mercedes-AMG, a brand known for its commitment to high-performance vehicles, is addressing this demand with a new V8 engine.
The new Mercedes-AMG CLE63 V8 is the engine that many fans have been hoping for. While official details are still under wraps, insiders suggest it is a masterpiece that will set a new standard for performance coupes in the United States. This article will delve into the specifics of this new engine, its implications for the automotive industry, and what it means for Mercedes-Benz’s future product strategy.
Adam Chamberlain, CEO of Mercedes-Benz USA, has confirmed that a CLE63 is in the works. Early prototypes have been driven by executives, who describe it as phenomenal and worth the wait. This new V8 model is a response to the high demand for powerful V8-powered cars in the American market.
Engine Specifications and Performance
The heart of the new Mercedes-AMG CLE63 is the 4.0-liter twin-turbo V8 engine. This engine features a flat-plane crankshaft, a technology typically found in high-performance engines, which contributes to better exhaust scavenging and higher peak power.
The flat-plane crank design is a significant departure from the cross-plane crankshaft found in many production V8s. It results in a more linear power delivery, a distinctive engine note, and improved throttle response. While details on the specific power output of the CLE63 are not yet available, it is expected to outperform the current CLE53 model.
In the 2027 S-Class, the 4.0-liter twin-turbo V8 produces 530 horsepower and 553 lb-ft of torque. This configuration is also available in the 2027 GLE580 and GLS580 SUVs. AMG is expected to tune this engine further for the CLE63, delivering even higher power and torque figures.
Mercedes-Benz’s Renewed Focus on North America
The CLE63 is a reflection of Mercedes-Benz’s renewed focus on the North American market. In other regions, electric vehicles are becoming increasingly popular, but in the United States, V8-powered cars remain highly desirable.
Mercedes-Benz is developing new products specifically for the American market, including the CLE63. This new V8 model is being built on a new platform that will support various powertrain options, including internal combustion engines, hybrids, and fully electric vehicles.
Engine Options in Other Models
The new 4.0-liter twin-turbo V8 with a flat-plane crankshaft is also available in the 2027 S-Class, providing refined yet powerful performance. Källenius describes it as a “wolf in sheep’s clothing,” with the AMG version serving as the “Alpha wolf.”
The 2027 GLE580 and GLS580 SUVs also feature this new V8 engine. In these SUVs, the engine produces 530 hp and 553 lb-ft of torque, delivering a blend of luxury and performance.
For the CLE53, Mercedes-AMG utilizes a plug-in hybrid-boosted 3.0-liter inline-six engine with 577 hp. This configuration provides a balance of performance and efficiency, offering a compelling alternative to V8 models for those seeking fuel economy.
Future Outlook and Industry Trends
The CLE63 is part of Mercedes-Benz’s global product offensive, with 40 new vehicles planned over the next three years. This strategy reflects the company’s commitment to offering a wide range of powertrain options to meet diverse customer preferences.
While Mercedes-Benz is investing in electrification, it remains committed to internal combustion engines. The company understands that V8 engines continue to be popular in the U.S. market and is working to ensure that these engines meet future emission regulations.
Chamberlain has hinted at the possibility of a V8 engine in future E-Class or C-Class models. However, the business case for a high-performance E63 wagon is questionable, given that North America is its primary market.
Conclusion
The upcoming Mercedes-AMG CLE63 V8 is a significant development for the automotive industry. It reflects Mercedes-Benz’s commitment to providing powerful, high-performance vehicles that meet the demands of V8 enthusiasts.
