2014 Mercedes-Benz C63 AMG spied testing at Nürburgring
The next-generation Mercedes-Benz C63 AMG has been spotted undergoing high-speed development at the Nürburgring, with major changes expected under the bonnet.
Mercedes-Benz engineers have been pushing the 2014 C63 AMG prototype hard at the Nürburgring as the brand prepares its next flagship C-Class performance saloon. The test car, heavily camouflaged, was photographed lapping the circuit in late summer 2013, signalling that AMG is in the advanced stages of chassis and powertrain development. The Nürburgring is a well-known testing ground for high-performance vehicles, offering a challenging mix of corners and elevation changes that allow engineers to fine-tune handling and durability.

Engine Changes and Performance Expectations
The C63 AMG has long been known for its 6.2-litre naturally aspirated V8, but this generation is widely expected to move to a smaller, twin-turbocharged engine. While early speculation suggested the 5.5-litre twin-turbo V8 from the E63 AMG, more credible sources and industry observers now point to an all-new 4.0-litre twin-turbo V8 being developed specifically for the C63. This would bring the C-Class in line with AMG’s latest engine strategy, focusing on greater efficiency and reduced weight without sacrificing outright performance.
Output figures have not been officially confirmed, but the new engine is expected to deliver around 500 to 525hp, matching or exceeding the outgoing model’s 457hp and keeping the C63 competitive with rivals such as the BMW M3 and Audi RS4. The move to turbocharging should also boost torque and lower emissions, addressing both performance and regulatory demands. This change represents a significant shift for AMG, which has been known for its large-displacement, naturally aspirated engines. The new engine is expected to offer a balance between raw power and improved fuel efficiency, reflecting broader trends in the high-performance segment.
Chassis and Visual Changes
Camouflage on the Nürburgring test car covers most of the new bodywork, but several AMG hallmarks are visible. The prototype rides on larger wheels and tyres, and the brakes are significantly upsized compared to standard C-Class models. The car’s stance appears lower and wider, suggesting a revised suspension setup. Quad exhaust outlets and a deeper front bumper hint at the aerodynamic and mechanical upgrades typical of AMG’s high-performance variants.
Aerodynamic tweaks are expected to include a new front splitter, rear diffuser and side skirts, all aimed at improving high-speed stability and cooling. AMG’s focus on chassis tuning should result in sharper handling, which is critical for the C63’s appeal against its German rivals. The larger brakes and upgraded suspension system will likely contribute to improved stopping power and cornering capability, further enhancing the car’s track credentials. These changes are consistent with AMG’s approach to creating distinct, performance-focused models within the Mercedes-Benz lineup.
Expected Debut and Market Context
The new C-Class range is due to be revealed in early 2014, with the C63 AMG expected to follow soon after. Industry sources suggest a possible unveiling at the Geneva Motor Show, though Mercedes-Benz has not confirmed a date. The new AMG will compete directly with the next-generation BMW M3 and Audi RS4, both of which are also moving towards turbocharged engines and advanced chassis technology. This competition is expected to push manufacturers to focus on both performance and efficiency, as emissions regulations become more stringent across Europe and other markets.
The shift to a newly developed 4.0-litre twin-turbo V8 marks a departure from AMG’s long-standing tradition of large naturally aspirated engines. This move reflects broader industry trends, as performance car manufacturers seek to maintain high output while meeting modern emissions standards. The C63 AMG’s anticipated power figures and advanced chassis technology are designed to keep it competitive in a segment that is rapidly evolving. Enthusiasts and industry watchers alike will be keen to see how the new model performs, particularly given AMG’s reputation for delivering engaging, high-performance vehicles.
