The 2018 Mercedes-Benz C-Class remains a popular choice in the UK for drivers seeking a blend of luxury and performance. This review delves into the various aspects of the C-Class 2018 models, focusing on performance, engine options, and handling to give you a comprehensive understanding. We’ll primarily focus on the base turbo-4 variant, a common selection for UK buyers, while also exploring the exciting AMG versions.
The entry point to the C-Class range is the C300, available in several body styles. Under the bonnet, you’ll find a 2.0-litre turbo-4 engine producing 241 horsepower and 273 pound-feet of torque. For the 2018 model year, this engine is paired with a new 9-speed automatic transmission. Mercedes claims a 0-60 mph acceleration time of around 5.8 seconds, but the on-road experience of the base C300 feels even more responsive than the numbers suggest. It captures some of the engaging character of the smaller AMG models, offering plentiful low-end boost and immediate power delivery. While it may lack the distinctive exhaust note and high-revving nature of the full-fledged AMG, the C300 provides strong performance for a base model, with power sent to either the rear or all four wheels depending on the configuration.
For those interested in a more fuel-conscious option, the 2018 C-Class also offered the C350e plug-in hybrid. This model combines the same 2.0-litre turbo-4 engine with electric power to deliver a combined output of 275 hp. While specific details like official EPA ratings and pricing for the UK market may vary, it’s important to consider the characteristics of this hybrid variant.
C350e Hybrid Performance
The Mercedes-Benz C350e plug-in hybrid integrates an 80-horsepower electric motor between the 2.0-litre turbo-4 engine and a 7-speed automatic transmission. This setup results in the aforementioned 275 hp combined. One characteristic to note is that it doesn’t offer electric idle creep when stopped, which may require a slight adjustment for drivers accustomed to conventional automatics or other hybrids. The electric motor does contribute to initial acceleration, but its contribution is somewhat limited. When demanding more than moderate power, such as during motorway on-ramps, the petrol engine typically engages.
In terms of electric range, the C350e is rated for a modest all-electric range. Fuel economy improvements over the standard C300 are present, but they might not be as significant as some drivers expect. It’s crucial to assess if the plug-in hybrid’s electric capabilities and fuel savings align with your typical driving needs and charging access in the UK.
AMG C43 and C63 Performance Variants
Stepping up the performance ladder brings us to the AMG C43. This model features a twin-turbo 3.0-litre V-6 engine, producing 362 hp and 384 lb-ft of torque. This potent engine transforms the C-Class driving experience, achieving 0-60 mph in a swift 4.6 seconds. The acceleration is readily available across its nine forward gears, providing ample power for UK roads. The engine note is tuned to provide a balance of exhaust and induction sounds, hinting at its V-6 roots without being overly aggressive. The AMG ‘whuffle’ sound is a signature element, enhancing the driving experience. Standard rear-wheel drive is offered, while an all-wheel-drive system is available, featuring a 33/67 torque distribution and electronic torque vectoring for enhanced handling.
For the ultimate performance enthusiast, the C63 AMG represents the pinnacle of the 2018 C-Class range. It boasts a twin-turbo 4.0-litre V-8 engine, offered in two output levels. The standard C63 delivers 469 hp and 479 lb-ft of torque, while the higher-output ‘S’ variant pushes this to 503 hp and 516 lb-ft. Both versions send power to the rear wheels through a 7-speed paddle-shifted dual-clutch transmission, unique within the C-Class lineup. The C63 S achieves a blistering 0-60 mph time of just 3.9 seconds and a top speed of 155 mph. Accompanied by a rich V-8 soundtrack, the C63’s distinctive roar is sure to attract attention. It is undeniably a high-performance machine capable of easily overpowering its rear tyres.
Ride and Handling of the 2018 C-Class
The 2018 C-Class demonstrates significant advancements in ride and handling, closing the gap with rivals in its class. The electric variable ratio steering provides precise control and genuine feedback, with a responsive steering ratio.
The C-Class chassis features an independent suspension system, with the option to upgrade from standard steel coils to air springs and continuously adjustable dampers with selectable driving modes.
Across its various driving modes—Comfort, Eco, Sport, and Sport+—the air suspension delivers a refined and comfortable ride while effectively managing body roll. This allows the car to remain composed even through tight corners, a characteristic often associated with sportier sedans rather than traditional luxury cars. This sport-oriented handling is particularly fitting for the AMG C43 and C63 models.
AMG-Enhanced Ride and Handling
The AMG models elevate the driving experience further. Driving impressions of the AMG C63 S Coupe highlight even sharper steering response, thanks to a wider track and retuned power steering with added weight and feel.
A key strength of the AMG models is their surprisingly compliant ride quality, making them suitable for daily driving in the UK. The ride is continuously adjusted via variable dampers, while the C43’s all-wheel-drive system features a dynamic power split. The C63 remains true to its performance roots with rear-wheel drive. AMG models also benefit from upgraded brakes, and the C43 includes five transmission modes, including a manual mode with rev-matching, along with a sport exhaust for a more aggressive sound.
Tyre specifications for the AMG models, such as the Michelin Pilot Super Sport tyres (255/35ZR19 front and 285/30ZR20 rear on the C63 S, with 19s all around on the standard C63), provide substantial grip and contact. While offering excellent performance, these tyres might not be as track-focused as some competitors’ offerings.
Overall, the AMG versions of the 2018 c class mercedes offer a more cohesive and sharper driving experience compared to the standard C-Class range, and arguably surpass competitors in terms of overall driving dynamics. The 2018 Mercedes-Benz C-Class range provides a diverse selection to UK drivers, from the refined and efficient C300 to the exhilarating AMG models, catering to a variety of preferences and driving styles.
