Take heart, automotive enthusiasts and long-time Mercedes-AMG fans: a new Mercedes-AMG CLE63 equipped with a powerful and refined V-8 engine is on the way. According to key executives we’ve spoken with, the all-new CLE63 is poised to be a truly exceptional vehicle—a rare feat in today’s increasingly electrified automotive landscape.
While Mercedes has yet to confirm the official launch date for the all-new CLE63 coupe and convertible, it is no longer just a rumor; it is a reality. Prototypes have already been seen undergoing rigorous testing, giving us a glimpse into the performance and luxury that this next-generation model will offer. Although it won’t be available this year, Adam Chamberlain, CEO of Mercedes-Benz USA, emphasizes that it will be an “unbelievable car” and “well worth the wait.”
The CLE63: A Case Study in U.S. Market Focus
A car like the CLE63 holds significant importance for Chamberlain and the North American Mercedes-Benz team. Projections indicate that an astonishing 95 percent of all CLE63 sales are expected to originate from the United States. Consequently, the new CLE63 is being meticulously engineered and developed as an American-spec car—a vehicle specifically tailored to meet the discerning demands of the U.S. luxury performance market.
This strategic focus on the North American consumer base has significant implications for engine choices and overall vehicle character. Unlike some markets that have largely transitioned to hybridization or electrification for performance vehicles, the U.S. market remains deeply committed to the V-8 engine. Mercedes-Benz recognizes this enduring preference, making the development of a new, clean, and powerful V-8 engine not just a nod to enthusiasts, but a strategic business imperative.
A New Generation of V-8 Power: The 4.0-Liter Twin-Turbo V-8
The heart of the forthcoming Mercedes-AMG CLE63 will be a revolutionary new V-8 engine. This powerplant has been developed by Mercedes-Benz to strike a delicate but crucial balance: it retains the exhilarating high-performance character that defines AMG vehicles while significantly reducing emissions to comply with stringent future regulations.
This cutting-edge 4.0-liter twin-turbo V-8 engine, distinguished by its flat-plane crankshaft, is not entirely new to the Mercedes-Benz lineup. It has already made its debut in the 2027 Mercedes-Benz S-Class, providing a quiet yet immensely potent driving experience that embodies the concept of a “wolf in sheep’s clothing.” Furthermore, this engine will power the upcoming 2027 Mercedes-Benz GLE580 and GLS580 SUVs, both of which recently underwent their global premieres. In these applications, the engine produces a robust 530 horsepower and 553 lb-ft of torque. Not surprisingly, AMG has confirmed that it will be tuning specialized performance variants of this new V-8, ensuring that the Mercedes-AMG CLE63 will deliver blistering performance.
AMG’s V-8 Legacy: What’s Next for E-Class and C-Class?
Does the introduction of this new Mercedes-AMG CLE63 signal a resurgence of V-8 engines in other high-performance Mercedes models? According to Chamberlain, this question remains unconfirmed at this time. Like many enthusiasts who appreciate the raw power and emotive sound of a V-8, he expressed a desire for an E63 wagon. However, the business case for such a vehicle remains questionable, particularly considering that North America represents the only viable market for it.
Fortunately, buyers seeking high performance in a practical package are not entirely without options. The automaker already offers a highly competitive choice in the form of the E53 wagon, which is powered by a plug-in-hybrid-boosted version of the company’s 3.0-liter inline-six engine, delivering an impressive 577 horsepower.
A similar variant of that six-cylinder engine, producing 443 horsepower, currently sits under the hood of the most powerful CLE model available today—the Mercedes-AMG CLE53. Unlike the wagon, the CLE53 does not utilize a plug-in hybrid system. It can be presumed that any forthcoming CLE63 will generate significantly more power through an AMG-tuned version of the aforementioned new twin-turbo V-8 engine.
Renewed North American Focus: The CLE63 as a Symbol of Strategy
The CLE63 is more than just a new car; it is a clear symbol of Mercedes’ renewed strategic focus on the North American market. Chamberlain confirmed that V-8-powered cars remain significantly more desirable among U.S. consumers than in many other regions around the world. In addition to the Mercedes-AMG CLE63, there are plans to launch two or three additional products that are being developed specifically for the North American market. These vehicles are being built on a new platform that is expected to be capable of supporting a V-8 engine, ensuring that the brand can continue to meet the high-performance demands of its American clientele.
These initiatives are part of a massive global product offensive being undertaken by Mercedes-Benz, Mercedes-AMG, and Maybach. The automaker plans to launch 40 new vehicles across its divisions within the next three years. This comprehensive strategy encompasses a wide range of powertrain options, including internal combustion engines, hybrids (including plug-in hybrids), and fully electric vehicles. This diverse product portfolio ensures that Mercedes-Benz remains at the forefront of the automotive industry, offering choices for every type of driver and every market segment.
Committed to V-8s for U.S. Customers
Investing in and developing new V-8 engines demonstrates a profound commitment to this powerful powerplant, according to Mercedes-Benz Group CEO and Chairman of the Board of Management, Ola Källenius. More broadly, he states, this investment signifies a dedication to meeting the needs of U.S. customers. For decades, the V-8 engine has been a cornerstone of high-end and high-performance Mercedes-Benz vehicles in the United States.
Källenius described the new V-8 engine launching in the 2027 S-Class as providing “quiet but dominant performance.” He characterized it as a “beast but in the background,” stating, “That is the wolf in sheep’s clothing.” However, Källenius emphasized that “the wolf really comes out with the AMG version, so there will be a wolf and an Alpha wolf coming.” He concluded by saying, “V-8 fans in the U.S. are absolutely going to love that.” Based on the information available so far, it appears that V-8 fans in the United States will indeed be very pleased with what is coming under the hood of the new Mercedes-AMG CLE63.
What to Expect from the New Mercedes-AMG CLE63
While specific details about the Mercedes-AMG CLE63 are being closely guarded, the recent world debuts of the 2027 Mercedes-Benz GLS and GLE SUVs took place at the automaker’s Alabama factory, reinforcing the importance of this region in the company’s product strategy. This venue is a testament to the investment in U.S. manufacturing and development.
Based on what we know about the new 4.0-liter twin-turbo V-8 with a flat-plane crankshaft, the Mercedes-AMG CLE63 is expected to be a significant departure from the previous generation. The use of a flat-plane crankshaft, often associated with racing engines, helps to improve engine balance and responsiveness while also allowing for higher-revving capabilities. This engineering choice suggests that AMG is pushing the boundaries of what is possible with a road-going V-8, aiming to provide a driving experience that is both exhilarating and refined.
Performance and Drivetrain Configurations
The AMG team’s expertise in engine tuning will undoubtedly play a crucial role in maximizing the potential of the new V-8 in the CLE63. While the standard GLE580 and GLS580 produce 530 horsepower, AMG is known for pushing performance to the next level. It is reasonable to expect that the Mercedes-AMG CLE63 will feature an engine producing significantly more power than the current Mercedes-AMG CLE53, which offers 443 horsepower from its inline-six.
Some rumors suggest that the CLE63 could feature an AMG E Performance plug-in hybrid system, similar to the one used in the E53 wagon. This would combine the power of the V-8 with an electric motor to provide even greater acceleration and efficiency. However, the primary emphasis for the U.S. market remains on the pure power and emotional appeal of the V-8. Whether it is a traditional V-8 or a hybridized variant, the Mercedes-AMG CLE63 is sure to deliver a thrilling driving experience.
Competition and Market Position
The Mercedes-AMG CLE63 will compete in the highly competitive luxury sports coupe segment. Its primary rivals will include vehicles such as the BMW M4 and the Audi RS 5. By leveraging its new V-8 engine and AMG’s engineering prowess, the CLE63 is positioned to hold its own against these formidable competitors.
