Mercedes-AMG C 63: The Potential Return of the Inline-Six Engine

Instructions

This article explores the potential shift in Mercedes-AMG's C 63 S E Performance model, focusing on the possibility of a return to a six-cylinder engine, a change eagerly anticipated by many enthusiasts.

Mercedes-AMG C 63: Reimagining Performance, Rekindling Passion

The Current Hybrid Powertrain: A Source of Debate Among Enthusiasts

The Mercedes-AMG C 63 S E Performance currently features a plug-in hybrid system that produces an impressive 671 horsepower and 752 pound-feet of torque. However, the use of a turbocharged 2.0-liter inline-four internal combustion engine has sparked considerable debate among fans, many of whom miss the powerful V8s of previous C 63 models. Mercedes seems to be taking this feedback into account.

Exploring New Engine Options: A Hint at the Future

Mattias Geisen, a Mercedes board member for sales and marketing, indicated a possible shift towards offering six-cylinder options in future models where four-cylinder engines are currently used. He suggested that these new configurations could be either hybrid or purely internal combustion, implying a potential departure from the current four-cylinder setup in the C 63. This statement opens the door for a more diverse engine lineup in the brand's performance vehicles.

The Inline-Six: A Fit for the C-Class?

The introduction of a six-cylinder engine would likely involve a variant of the turbocharged 3.0-liter inline-six already present in other AMG models, though not in the flagship '63' versions. This engine, equipped with a 48-volt mild-hybrid system, delivers strong performance, exemplified by its 443 hp and 413 lb-ft of torque in the AMG CLE 53. While it may not replicate the V8's raw sound, an inline-six would offer a unique character within the C-Class range, which predominantly features turbo-four engines. The shared platform with the CLE-Class suggests that a longer inline-six could comfortably fit into the sedan's engine compartment, making this a feasible option without requiring extensive structural modifications that a V8 might entail.

Balancing Innovation with Tradition: The C 63's Hybrid Journey

The existing turbo-four plug-in hybrid system in the C 63 and GLC 63 S E Performance is a testament to advanced engineering. Its gasoline engine, lauded for being the highest-output volume-production four-cylinder, works in conjunction with an electric motor and F1-derived battery technology to deliver efficient performance. This F1-inspired approach emphasizes power with efficiency, yet it results in a heavier and more intricate vehicle compared to non-hybrid alternatives, and some argue it lacks the emotive engine note of its predecessors. Despite its technical prowess and superior specifications, the emotional connection and traditional appeal of a powerful engine remain a significant factor for buyers, underscoring the challenge of balancing technological innovation with established preferences.
