Fans of Mercedes-AMG who have been disappointed with the brand’s recent super sedans might have something to look forward to. According to a report from Car and Driver, the upcoming 2026 models of the C63 and E63 will once again be powered by V8 engines.
Sources mentioned in the story suggest that the C-Class and E-Class are undergoing modifications to accommodate the M177 4.0-liter V8 engine. This marks a significant upgrade from the current C63’s 2.0-liter turbo four hybrid engine. While the current engine delivers 671 horsepower and 752 pound-feet of torque, some enthusiasts find its sound lacking, making the V8’s electrified version even more appealing, possibly generating up to 831 hp in the GT63S E Performance.
Adapting the 4.0-liter V8 engine to comply with EU7 emissions standards is also part of the plan, as reported by Car and Driver, with Mercedes-AMG actively working on meeting these stringent regulations.
Reportedly, senior engineers claim that accommodating the larger V8 engine in the C63 and E63 models won’t require significant modifications. Despite the added size, twin turbos, plug-in hybrid battery, and associated equipment, the transition is expected to be relatively straightforward, a key factor in meeting the deadline for the V8 reintroduction by 2026.
Mercedes-AMG’s move towards technologically advanced four-cylinder hybrids drew criticism from enthusiasts and the public alike. The lack of the same level of excitement compared to V8 engines becomes apparent, especially with competitors like the upcoming BMW M5 rumored to feature a hybrid twin-turbo V8. If such comparisons arise, affluent car enthusiasts may find little reason to consider a 2.0-liter Mercedes against the competition.
The Drive contacted Mercedes-AMG for a comment, but a spokesperson declined to provide any information.
