Mercedes-AMG abandoning 4-cylinder PHEV models for six-cylinder and, indeed, V8 variations

Mercedes-AMG seemingly intends to scrap the potent 500 kW/1020 Nm four-cylinder PHEV powertrain from the C 63 and opt for a fresh V8 engine, following customer criticism.

Mercedes-AMG Shifts Focus: Phasing Out Four-Cylinder PHEV Powertrains and Embracing New V8 Engines

In a significant strategic shift, Mercedes-AMG has announced plans to phase out the four-cylinder plug-in hybrid powertrain from the Mercedes-AMG C 63 and GLC 63 models. This decision comes as the company is committed to a 'dual-drivetrain strategy', with both the electric and electrified internal-combustion engine pillars expected to grow significantly.

The four-cylinder engine, paired with an electric motor, was introduced in 2022, but it drew criticism from enthusiasts for its lack of character and the drivetrain's weight compared to its V8-powered predecessor. Despite its technical advancements and performance, the engine failed to resonate with traditional Mercedes customers.

Markus Schäfer, Mercedes-Benz CTO, and Steffen Jastrow, AMG Development Director, have confirmed that AMG and Mercedes are collaborating on a brand-new V8 engine. The development of this high-tech V8 is primarily carried out by the engineers at Mercedes-AMG in Affalterbach, with Jastrow leading the project. The new V8 engine is being developed to meet upcoming Euro 7 emission regulations and is expected to debut by the end of 2027.

The upcoming petrol-powered Mercedes-AMG models will adopt either an updated version of the inline six-cylinder engine or an all-new V8 featuring a flat-plane crankshaft. Both engines will be electrified with either 48V systems or full hybrid set-ups.

The electric pillar in the Mercedes-AMG models will also grow significantly. Mercedes is investing heavily in the electrification of its vehicles, aiming to provide customers with more sustainable and high-performance options.

The phase-out of the four-cylinder engine represents a significant change in Mercedes-AMG's engine line-up. However, the second pillar - electrified internal-combustion engines - will remain in the Mercedes-AMG models. The company is committed to providing a diverse range of powertrains to cater to the varying needs and preferences of its customers.

The Mercedes-AMG C 63 and GLC 63 models, equipped with a 500kW/1020Nm 2.0-litre plug-in hybrid powerplant, haven't been a hit with buyers. The revelation of this phase-out was made at the recent reveal of the AMG GT XX Concept.

Despite the criticism and the phase-out, it's important to note that the four-cylinder engine is right up there on performance. It's one of the most advanced drivetrains available in a production car. However, the investment required to make the four-cylinder engine comply with Euro 7 emission regulations is 'very high'.

This move by Mercedes represents a commitment to providing its customers with high-performance, sustainable, and technologically advanced vehicles. The company is focusing on delivering the best possible driving experience while meeting the evolving needs and expectations of its customers.
