Why is the Mercedes-Benz C63 called 507?

[VonMicah]

507 is a special edition of the Mercedes-Benz C63, with the full name Mercedes-Benz C63 AMG Edition 507. This model has a maximum horsepower of 507, which clearly distinguishes it from other versions, hence the name 507 for this variant of the Mercedes-Benz C63. Here is some additional information: 1. Model: The Mercedes-Benz C63 is a high-performance coupe from Mercedes-Benz. With its dynamic appearance and outstanding performance, it has become the top choice for elite individuals who pursue sports and self-expression. 2. Exterior: The Mercedes-Benz C63 incorporates a large number of mainstream and stylish LED lighting elements, among other optical diodes. The headlights feature an SL-inspired design, and even the taillights are equipped with LED technology. 3. Features: The most notable feature of the Mercedes-Benz C63 is its ability to embody the essence of a Mercedes-Benz sedan in every aspect, offering comfort, ease of handling, and safety during long-distance drives. 4. Powertrain: The Mercedes-Benz C63 is powered by a 6.3-liter naturally aspirated V8 engine, delivering an impressive 457 horsepower and 600 Nm of torque.

I remember when Mercedes-Benz launched the C63 507 Edition, it caused quite a sensation, and the key was in the number 507. It directly represented the car's horsepower—507 hp! The regular C63 had 481 horsepower, but the AMG department retuned that classic 6.2-liter V8 engine, using higher-strength piston connecting rods and optimizing the intake and exhaust systems. In fact, the name 507 was also a tribute to the legendary 1950s sports car, the 300 SLR, which had the internal code name W196S/507. I've driven a friend's 507 Edition, and it's much more aggressive than the regular C63, with particularly direct throttle response. The exhaust pops during cold starts sound almost like firecrackers. However, these kinds of large-displacement naturally aspirated cars are becoming increasingly rare, making this generation of the 507 a collector's item.

The number 507 represents the maximum horsepower of this car's engine. In 2013, Mercedes-Benz released a performance-enhanced version of the C63 AMG, boosting its original 481 horsepower to 507. They made several modifications, such as installing forged pistons to reduce weight, reinforcing the crankshaft bearings, and updating the engine software. Interestingly, the engine itself remained unchanged—it was still the M156 naturally aspirated V8—but AMG engineers managed to squeeze out an extra 26 horsepower. The car also came with wider Michelin Pilot Super Sport tires front and rear, as it would otherwise struggle for grip. I tested it on a track last year, and the acceleration in second gear felt like being kicked in the back. Unfortunately, new cars today mostly come with turbocharged engines, and this kind of pure, high-displacement naturally aspirated power is nearly extinct.

Mercedes-Benz named this car the 507 purely because of its power specifications. The regular C63 AMG had 457 horsepower, which increased to 487 hp in the 2012 model, while the 507 version broke through the 500 hp mark with a full suite of performance upgrades. The main upgrades were in the engine, featuring newly designed camshafts and valve mechanisms, paired with a more efficient cooling system. Actually, the name also carries a historical reference—Mercedes produced a 507 Roadster in 1957, and this is somewhat of a classic revival. Most buyers of the 507 version were drawn to its limited-edition status, as only a few thousand units were produced globally at the time. What I find most brilliant about it is how it retains that raw mechanical feel—the transmission clunks satisfyingly during gear changes, making it far more authentic than the newer, more electronically infused AMG models that came later.

507 refers to this car's output level of 507 horsepower. When Mercedes-Benz launched this version in 2013, they conducted in-depth optimization on the original 6.2-liter V8 engine. Specifically, engineers redesigned the piston crown shape to increase compression ratio, reinforced the crankcase ventilation system, and even replaced the intake piping with a smoother design. These modifications allowed the engine to rev up faster, with the redline zone extended by an additional 500 rpm. In fact, the name contains an Easter egg—Mercedes had a model called 300 SL 507 as early as the last century, making this a tribute to classic heritage. Those who've driven it know the 507 version has much sharper throttle response than the standard model, especially in sport mode where the downshift blip sounds thunderously impressive.

The number 507 represents the vehicle's maximum horsepower output. When Mercedes-Benz launched the high-performance C63 AMG variant, they specially tuned the engine to break the 500-horsepower threshold. Key upgrades included forged aluminum pistons, reinforced connecting rod bearings, a high-flow air filter, and even a complete rewrite of the ECU programming. Interestingly, the transmission gear ratios were also adjusted, allowing the car to hit 100 km/h in third gear effortlessly. The name "507" was partly a marketing strategy—the number stands out much more prominently than the Porsche 911 Carrera S's 400 horsepower. During actual driving, you can distinctly feel the rear wheels being particularly lively, with the tail slightly swaying under full-throttle launches. This raw mechanical sensation is something you won't find in the current turbocharged C63, which is why the 507 edition holds its value exceptionally well in the used car market.
