In an interview during the Monterey Car Week, Michael Schiebe did not hesitate to "definitely deny" rumors that the C63 and E63 would return to V8 power. The AMG boss went on to say that the decision to downsize and electrify was the right one, as competitors are also coming out with sporty hybrids with smaller engines.
As a result, the C63 will retain its plug-in hybrid based around a 2.0-liter, four-cylinder engine, while the E63 is expected to utilize a 3.0-liter inline-six mill and become a PHEV as well. Pictured above, the "Final Edition" of the two previous-generation high-performance sedans marked the end of the road for the eight-cylinder models.
As we can see, time is running out for large internal combustion engines. That's especially true in the European Union, where stricter emissions regulations are forcing automakers to downsize and/or electrify. With Euro 7 standards set for 2025, the days of large gasoline motors are counted.
