The Mercedes-Benz C63 vs. Mercedes-Benz E63 AMG. The Mercedes-AMG C63 and E63 are two of the most well-known AMG performance cars. They first appeared in 2007/8 amid much fanfare and hype, and customers were enthusiastic about the new arrivals. The original C63 AMG and E63 AMG models both had great performance, attractive appearance, a luxury and spacious cabin, and, of course, cutting-edge technology. Drivers had already appreciated the Mercedes C-class and E-class, and the AMG tuned C/E63 models added to that tradition.
The C63 AMG has traditionally been seen as the less powerful relative of the E63 AMG, and this is not entirely incorrect. It’s worth noting, though, that the E63 costs $20,000-$30,000 more. They both offer high performance S-badged variations in addition to ordinary models. The AMG C63 S and E63 S both have more power through updated tuning and engine components, as well as enhanced speed and rev limiters and higher performance brakes than the normal variants.
Mercedes-Benz discontinued the C63 AMG in 2021 and the E63 S AMG in 2022, although they will be reintroduced in 2023 with significant upgrades. They will most likely have a considerably smaller 2.0L engine, a 48v hybrid electric starter-generator system, and an electric turbo. Mercedes has stated that the power will be at least similar to the departing models, although official information has been scarce.
This guide will explore at the C63 and E63 AMGs’ history, engines, typical problems, and performance. First, let’s look at the history, performance, and evolution of both vehicles from their first generations to the present.
Mercedes C63 versus E63 AMG Performance & History
The Mercedes-AMG E63 first appeared in the North American market for the 2007 model year, with the AMG C63 following closely behind in 2008. Both models’ jaw-dropping performance, sleek styling, and luxurious and comfortable interiors wowed reviewers from the start. They both had naturally aspirated V8 engines that howled down the road while horrifying roars erupted from their quad tailpipes. Mercedes eventually abandoned natural aspiration in favor of slightly smaller biturbo V8s, which enhanced power output and responsiveness across the board.
Mercedes’ response to the BMW M3 was the C63 AMG, and the E63 AMG was designed to compete with the BMW M5. They are both worthy rivals, with comparable performance and power numbers. Fortunately, the German carmakers’ rivalry is to the benefit of performance enthusiasts, as they continue to produce beautiful sedans capable of massive performance.
W204 (2008-2014) C63 AMG
The Mercedes M156 engine powered the first generation C63 AMG. The M156 is a 6.2L naturally aspirated V8 with a silicone-aluminum block. The M156 produced 451 horsepower and 443 torque, and it received rave reviews for its quickness, power, and sound. Unfortunately, the M156 had dependability concerns, which we shall discuss further below. We have examined the M156 in depth with our engine guide, so be sure to read that for the complete overview.
The W204 C63 AMG accelerates from 0 to 60 mph in 4.5 seconds and reaches 117 mph in 12.1 seconds. It is coupled to a 7-speed automatic transmission, which sends power to the rear wheels. Reviewers commend its suspension for having robust spring and shock rates while cruising without feeling stiff or harsh. It also has 18-inch wheels and excellent six-piston caliper brakes.
The W204 C63 AMG had a facelift in 2012, which included a reworked front fascia, grille, and new LED illumination. There were other performance packages available for the C63, which improved power by 30-hp, included forged internals, and enhanced peak speed. Mercedes created the C63 AMG Edition 507 for the W204’s final year, which increased power to 507 horsepower and included redesigned seats, wheels, and a special black-series hood. The increased power was achieved by using the E63 AMG tuned version of the M156.
C63 AMG and C63 S AMG W205 (2015-2021)
Mercedes-Benz introduced a new version of the C63 AMG in 2015, which included the high-spec C63 S AMG, and they both shared the same engine, a 4.0L biturbo 32 valve V8 known as the M177 DE 40 LA. The M177 evolved from the previous generation M176 and is equipped with twin BorgWarner single-scroll turbos. Mercedes boosted the power of the C63 AMG to 469 horsepower and 479 torque, and the C63 S to 503 horsepower and 516 torque.
The W205 C63 AMG accelerates from 0 to 60 mph in 3.8 seconds, while the S variant takes only 3.7 seconds. At 122 and 123 mph, quarter mile times were 12.0 and 11.9 seconds, respectively. The W204’s 7-speed transmission was retained until 2018, when it was replaced by a new 9-speed automatic transmission to power the actual wheels. The W205 was quickly praised for its agile handling and excellent chassis responsiveness. The automatic transmission’s swift and intelligent shifting was highly praised by critics.
The C63/C63S AMGs underwent facelifts in 2019, along with the rest of the C-class series. The facelift offered new color options, improved appearance, increased safety features, and a larger infotainment display. Mercedes canceled the C63/C63 S AMGs after the 2021 model year, owing in part to the high emissions output of its huge V8 engines. The C63 AMG will be back in 2023, powered by a 2.0L inline-4 engine and an electric-hybrid drivetrain.
W211 (2007-2009) E63 AMG
The W211 E63 AMG is equipped with a performance version of the 6.2L M156 V8, which was also used in the first generation C63 AMG the following year. The key differences are the forged pistons, lighter crankshaft, and AMG tuning. It accelerates from 0 to 60 mph in 4.2 seconds and completes the 14 mile in 12.7 seconds at 112 mph.
The W211 E63 produces 507 horsepower and 465 torque. It’s coupled to a 7-speed automatic transmission, which sends power to the rear wheels. Speedshift, a new feature of the transmission, made more intelligent shifting judgments and changed gears 50% faster. The audio and navigation systems in the cabin were also updated for the 2009 model year.
E63 AMG and E63 S AMG W212 (2010-2016)
The W212 E63 AMG continued to use the M156 engine until the 2012 model year, when AMG transitioned to the M157 5.5L biturbo V8. The M157 is powered by dual Garrett MGT2260SML turbos that produce 13 PSI (.9 bar) of boost. It features a 10.0:1 compression ratio, a new direct injection system, and sodium-filled exhaust valves. The W212 E63 sprints from 0 to 60 mph in 4.0 seconds and covers the 14 mile in 12.5 seconds at 115 mph. We already discussed typical issues with the M157 engine, so make sure to read that guide if you have any M157-related inquiries.
Mercedes also totally redesigned the suspension for the W212 generation, with firmer springs and shocks, beefier anti-roll bars, and adjustable dampers. Several new features were also introduced with the mid-generation facelift in 2014. Mercedes first introduced the high-end E63 S model and altered the driving train. Mercedes’ 4MATIC AWD system was made standard on all E63s, and rear wheel drive was no longer an option.
Beginning in 2016, Mercedes eliminated the regular E63 for the North American market, leaving just the E63 S AMG as an option. The initial power output for the 2012-2015 E63 AMG equipped M157 was 518 horsepower and 516 tq. With the P30 performance package, it increased to 550 horsepower and 590 tq. The P30 package became standard on all E63s in 2014. The 2014-2016 E63 S AMG utilised the same engine but gained 577 horsepower and 590 tq as a result of increased boost pressure.
E63 S AMG (4MATIC+ AWD) W213 (2018-2022)
The E63 S AMG took a break for the 2017 model year before returning with a fury – with a new engine. The M177 DE LA 40 engine from the W205 C63/C63 S AMGs is used in the W213 generation. The engine is a 4.0L biturbo 32 valve V8 with direct injection. Mercedes improved the turbos of the E63 S compared to the C63/C63 S AMGs. The E-series has twin-scroll turbos rather than single-scroll, which improves performance and efficiency.
The third generation E63 S AMG produces 603 horsepower and 627 torque. It accelerates from zero to sixty miles per hour in just 3.0 seconds. It can also run the 14 mile in 11.1 seconds at 126 mph, matching the 1,000-pound Porsche 911. The power range of the M177 is incredible, with peak torque arriving early and lasting for days. Drivers frequently compliment the engine’s responsiveness and ability to pull like a freight train until it reaches redline.
Mercedes’ 4MATIC AWD technology is powered by a 9-speed automatic transmission. The E63 S AMG, on the other hand, has a new feature enabled: drift mode. This allows the driver to simulate a RWD drive train by disengaging the front two wheels. The W213 generation’s suspension, chassis, and transmission all receive high marks. In comfort mode, reviewers praise the smooth handling and suspension, and contrast it with the tight performance and quick chassis in sport mode.
Final Edition of 999
Mercedes released the E63 S AMG Final Edition for the E63 S AMG’s final year, 2022. It was limited to 999 units worldwide and looked very similar to the 2021 version, but with slightly different style. The blacked-out interior, napa leather seats, and a bespoke “1 of 999” console badge were among the additional features.
Mercedes C63 and E63 AMG Common Issues
Now that we’ve looked at the history and performance of the C63, C63 S, E63, and E63 S AMG, let’s have a look at some of the most prevalent engine problems. As previously stated, the M156 and M177 DE 40 LA engines are shared by the E and C classes. The M157 engine is also used in the E63 and E63S AMG from 2012 to 2016.
The M156 engine
We previously examined the M156 in full in our engine guide, so we will only provide a synopsis here. Check out the guide when you have a chance to get answers to all of your M156-related queries.
The most serious problem with the M156 engine was the head bolts. Mercedes constructed them incorrectly, and they were prone to corrosion, resulting in coolant leaks into the combustion chamber. In severe circumstances, the head bolts might entirely separate, causing enormous issues including hydro-lock. There are also several difficulties with valve train components such as cam adjusters, cam lobes, and lifters. They are all susceptible to early wear and have design problems in their lubricating systems.
Some of these issues, such as the head bolts, were addressed after 2011, but the E63 stopped using the M156 just one year later, in the 2012 model year. Nonetheless, the rest of the engine is fairly robust, and the bottom end is practically bulletproof.

The M157 engine
We’ve also previously discussed typical issues with the M157 engine, so check out that guide for a more in-depth look at it. Again, we’ll just give you a quick rundown.
The M157 struggled from numerous timing chain difficulties during its first year in the E-class. These were related to poor design that resulted in oil starvation, but they were mostly resolved after the 2012 and 2013 model years. Timing chains are frequently a problem for Mercedes engines, even AMG models.
Misfires and spark difficulties were also common with the M157, particularly in tuned and modded engines. The valve timing cover and coolant hoses regularly leak and must be replaced as well. Overall, it is a dependable engine, although there are a few minor concerns to be aware of. Again, as with the M156, the bottom end is flawless and can handle almost anything you throw at it. Regular maintenance with high-quality oil is the most effective strategy to avoid M157 problems.
Engine M177 DE 40 LA
Finally, the M177 DE 40 LA engine, which has been powering the most recent C63/C63 S and E63 S AMGs from 2015 and 2018. Because most drivers have not accumulated a large number of miles on their M177s, data on long-term problems is limited. The M177 is praised in most assessments for its dependability and quality.
The primary problems with the M177 have been connected to spark plugs and ignition coils. Some drivers report that their vehicles have misfired due to fouled plugs after only 30,000 miles. The main culprits have been identified as defective plugs and ignition coils. Unfortunately, it is not quite evident what caused the majority of the failures. Although the problem is not widespread among M177 drivers, it has affected at least a few.
Aside from spark issues and common problems like loose hoses, complaints on the M177 have been few and far between. Even severely modified drivers have remarked on the engine’s dependability and sturdiness. In classic Mercedes-AMG flair, this is about as bulletproof as it gets.
Other Common Issues with the C63 and E63 AMG
The majority of the other issues with the C63/C63 S and E63/E63 S AMGs are minor and relate to suspension and build quality. Many people complained about the early 7-speed transmissions on the C63/C63 S and pre-2018 E63 AMGs, primarily about rough downshifts, gears randomly skipping during acceleration, and loud popping and banging noises. Some of these issues were resolved by updated computer software, but not all — though most transmissions did not require rebuilding.
On both the C63 and E63 AMGs, the suspension is described as squeaky and clunky. It is strongly advised to inspect all bushings and other components after 80,000 miles due to reports of deterioration and severe wear. Control arms and struts are also common trouble spots.
Another major issue, which is more severe on the C63 than on the E63, is the frequency of rattles and squeaks. This includes not only the suspension but also the brakes, dashboard, doors, and mirrors. It may seem surprising, but these are fairly common complaints from even short-term tenants. Motor mounts also appear to deteriorate and fail over time, particularly on engines with over 100,000 miles on them.
Overall, the automobiles are rather dependable, and the most of the difficulties are minor in nature. Even if these issues aren’t world shattering, it’s crucial to acknowledge them.
Mercedes C63 versus E63 AMG Comparison
The Mercedes-Benz C63 and E63 AMG are two of the company’s most proficient performance vehicles. Both exude luxury, style, dependability, and, most importantly, power. Their S-badged variants take the standard models to new heights, churning out every last bit of fun. The C63 is by far the more inexpensive option, costing $20,000-40,000 less depending on extras and body design. However, the E63 AMG is AWD, whereas the C63 is RWD, giving it significant advantages off the line and in wet weather.
In terms of performance, the E63 S AMG is by far the most responsive and powerful, with the best suspension. Nonetheless, the C63/C63 S are worthy rivals, with only slightly detuned versions of the same 4.0L biturbo power plant. Even when compared to their E-class competitor, handling and reliability remain excellent.
Models from both classes are also extremely dependable, with relatively few engine problems on the whole. With the exception of very early series E63 AMGs with M156 head bolt and valve train difficulties, these cars and engines have been models of dependability and enjoyment.
