According to foreign automotive media Car and Driver reports, Mercedes-AMG C63 and E63 models in 2026 will return to using the V8 engine.
Mercedes is considering reintroducing V8 engines in the high-performance C- and E-Class models after reports that many AMG owners are unhappy with the current four- and six-cylinder powertrains.
The new C63 models feature a turbocharged plug-in hybrid four-cylinder engine, while the next-generation Mercedes-AMG E63 is rumored to feature a PHEV turbocharged inline-six.
It’s clear that the above engines won’t be able to compete with Audi and BMW. For BMW, it’s not clear about the next M3 / M4, but the successor to the current M5 will retain its V8 engine while adding an electric range.
For Audi, the upcoming performance models will also be PHEVs, but they won’t drop down to four cylinders.
Citing the outlet, Mercedes is busy updating its 4.0 V8 engine to meet the stricter Euro 7 emissions standards.
According to senior AMG engineers directly involved in the matter, the C63 and E63 will require only minor bodywork changes to accommodate the V8 twin-turbo engine, PHEV battery plus electric motor, and ancillary equipment.
