For the 2021 model year, the C-Class sedan lineup primarily consisted of the C 300, AMG C 43, and AMG C 63 models. Each of these models features a distinct powertrain, and consequently, a different horsepower output. The C 300 serves as the entry-level luxury sedan in the C-Class family. It’s powered by a 2.0-liter turbocharged inline-4 engine. This engine is known for its smooth power delivery and respectable performance, making it a great choice for everyday driving. It generates a solid 255 horsepower and 370 lb-ft of torque. This is more than enough grunt for confident acceleration and effortless highway merging. It’s a powerplant that balances efficiency with a satisfying level of responsiveness. For those looking for a step up in performance without venturing into full-blown AMG territory, the AMG C 43 is a fantastic option. This model typically features a more potent engine, often a twin-turbocharged 3.0-liter V6. In the 2021 C 43, this engine churns out an impressive 385 horsepower and 384 lb-ft of torque. The addition of two turbochargers significantly boosts power and torque, providing a much more exhilarating driving experience with quicker acceleration and a more aggressive engine note. It’s a perfect middle ground for enthusiasts who want performance with a touch of everyday usability. Finally, for the ultimate performance enthusiasts, Mercedes-AMG offers the AMG C 63 and its variants. The heart of the C 63 is usually a handcrafted V8 engine. For the 2021 C 63, we're talking about a 4.0-liter twin-turbocharged V8. This powerhouse delivers a staggering 469 horsepower and 479 lb-ft of torque in the standard C 63 model. If you opt for the C 63 S variant, the output is even higher, boasting 503 horsepower and 516 lb-ft of torque. These figures place the C 63 firmly in the supercar performance category, offering blistering acceleration and track-ready dynamics. It's an engine that sounds as aggressive as it performs, providing an unforgettable driving experience for those who demand the absolute best.

C 300: The Balanced Luxury Sedan

Let's start with the workhorse of the 2021 C-Class lineup, the C 300. If you're looking for a vehicle that perfectly balances everyday practicality with a premium feel and respectable performance, the C 300 is definitely worth your attention. The 2021 Mercedes-Benz C-Class horsepower for the C 300 model comes from a sophisticated 2.0-liter inline-4 turbocharged engine. Now, don't let the 'four-cylinder' label fool you, guys. This engine is a marvel of modern engineering, pumping out a very capable 255 horsepower and a healthy 370 lb-ft of torque. This power output is more than sufficient for most driving scenarios. Whether you're navigating city traffic, merging onto a busy highway, or cruising along scenic routes, the C 300 provides smooth, responsive acceleration. The torque figure, in particular, is noteworthy. It means that the engine delivers ample pulling power from lower RPMs, making the car feel lively and agile even without needing to rev it out excessively. This translates into a more relaxed and comfortable driving experience, as you won't constantly feel like you need to push the engine hard to get moving. Mercedes-Benz has also equipped the C 300 with a smooth-shifting 9-speed automatic transmission (9G-TRONIC). This transmission works seamlessly with the engine, optimizing power delivery and contributing to the car's overall efficiency. Fuel economy is a strong point for the C 300, especially considering its luxury segment and performance capabilities. You can expect competitive MPG figures, making it an economical choice for a premium sedan. Furthermore, the C 300 offers various driving modes that allow you to tailor the car's performance characteristics to your preference. You can select modes like 'Eco' for maximum fuel efficiency, 'Comfort' for a balanced ride, or 'Sport' for a more engaging and responsive throttle. This adaptability ensures that the C 300 can cater to a wide range of driving styles and moods. The C 300 is also available in both rear-wheel drive (RWD) and the popular 4MATIC all-wheel drive (AWD) configurations. The 4MATIC system enhances traction and stability, particularly in adverse weather conditions, providing an added layer of confidence and safety. So, while it might not have the raw power of its AMG siblings, the C 300’s 255 horsepower is part of a package that delivers a refined, comfortable, and surprisingly spirited driving experience, making it a standout choice in its class for those who appreciate luxury, technology, and balanced performance. It’s the perfect embodiment of a modern luxury sedan that doesn’t compromise on daily usability.

This engine provides a much more aggressive throttle response and a sportier exhaust note, truly embodying the AMG spirit. The AMG C 43 comes standard with AMG's performance-tuned 4MATIC all-wheel-drive system. This setup typically distributes power with a rear bias (e.g., 33:67 front to rear) to enhance handling dynamics and provide that signature AMG feel. The AWD system not only contributes to quicker acceleration off the line but also ensures excellent grip and stability, allowing you to confidently put the car's power down, even in less-than-ideal road conditions. Paired with the engine is an AMG-enhanced 9-speed automatic transmission (9G-TRONIC). This transmission is specifically calibrated for performance, offering faster shift times and more decisive gear changes, especially when in its sportier modes.
