2015 Mercedes-Benz C63 AMG spied testing with new twin-turbo V8
Mercedes-Benz is preparing the 2015 C63 AMG with a new twin-turbocharged V8 engine, as the high-performance saloon has been caught testing ahead of its expected debut.
Mercedes-Benz engineers have been spotted testing the 2015 C63 AMG saloon, confirming that the next-generation AMG model will move to a new twin-turbocharged V8 engine. The prototype, seen in Germany, features AMG’s characteristic bodywork changes and is expected to make its public debut later in 2014. This marks a significant update for the high-performance version of the C-Class, as it transitions to a new powertrain and receives a range of technical and visual upgrades.
Introduction and Overview
Design and Styling Changes
While the prototype retains much of the standard 2015 C-Class silhouette, several visual changes mark it out as an AMG development. The front and rear ends are more aggressive, with larger air intakes and a deeper front bumper. Wider fenders and distinctive AMG alloy wheels are visible, suggesting a wider track and uprated suspension. At the rear, quad exhaust outlets and a subtle lip spoiler underline the car’s performance focus. These changes are in line with AMG’s approach to differentiating its models from the standard Mercedes-Benz range.
Interior details remain under wraps, but previous AMG models have featured sports seats, unique trim and AMG-specific instrumentation. The prototype’s heavily camouflaged cabin suggests further upgrades are likely for the production model, potentially including new materials, updated infotainment, and additional driver-focused controls.
New V8 Engine and Technical Upgrades
The most substantial change for the 2015 C63 AMG is the engine. The outgoing model’s naturally aspirated 6.2-litre V8 is being replaced by a 5.5-litre twin-turbocharged V8, known as the M157. This unit is already used in other AMG models and is expected to produce around 525hp in the C63 AMG, according to early information. The move to turbocharging reflects both emissions requirements and the need for greater efficiency, while maintaining the high power output AMG buyers expect.
Other technical changes include an upgraded braking system, revised suspension and a new AMG exhaust. These updates are designed to handle the increased performance and deliver the brand’s signature driving characteristics. The braking system is expected to feature larger discs and enhanced cooling, while the suspension will likely be retuned for sharper handling. The new exhaust system is also anticipated to provide the distinctive AMG sound, even with the addition of turbochargers.
Launch Timing and Market Positioning
The 2015 C63 AMG is expected to be unveiled officially later in 2014, with the Paris Motor Show in October seen as the likely venue. The new model will continue to rival the BMW M3 and Audi RS4, offering a blend of everyday usability and high performance. With the adoption of the new engine, Mercedes-Benz is positioning the C63 AMG to meet tightening emissions standards while keeping AMG’s reputation for power intact. This approach is in line with industry trends towards downsized, forced-induction engines for performance cars.
Further details, including final power output, performance figures and pricing, are expected closer to the official reveal. The move to a smaller, turbocharged engine is significant for AMG, as it marks a departure from the large-displacement, naturally aspirated engines that have long been a hallmark of the brand. Nevertheless, the anticipated power output and technical upgrades indicate that the C63 AMG will remain a strong contender in the high-performance saloon segment.
Comparison to Rivals and Market Impact
The Mercedes-Benz C63 AMG has traditionally competed with the BMW M3 and Audi RS4. With the new engine and chassis updates, the 2015 model is expected to maintain its competitive edge. The switch to turbocharging mirrors moves made by its main rivals, reflecting changing regulations and consumer expectations. Buyers can expect a car that balances everyday comfort with high levels of performance, advanced technology, and distinctive AMG styling.
As emissions standards become stricter, manufacturers are increasingly turning to turbocharged engines to deliver both power and efficiency. The 2015 C63 AMG’s adoption of the M157 engine is a direct response to these pressures, and its success in the market will likely influence future AMG models. The model’s unveiling at a major international auto show such as Paris is expected to draw significant attention from enthusiasts and industry analysts alike.
Summary of Expected Features
- 5.5-litre twin-turbocharged V8 engine (M157) expected to produce 525hp
- Upgraded braking system and revised suspension for improved performance
- Aggressive AMG-specific bodywork, including wider fenders and quad exhausts
