2025 Mercedes-Benz C 300 Sedan: Spacious, Efficient, and Sleek
The 2025 C 300 Sedan is a well-balanced luxury car that combines elegance, space, and aerodynamic efficiency. With seating for five and a cargo capacity of 11.6 cubic feet, the sedan is ideal for daily commuting and weekend getaways alike.
Exterior and Interior Dimensions
The C 300 Sedan stretches 187 inches long, is 80 inches wide (with mirrors), and stands 56.6 inches tall. With a coefficient of drag of just 0.24 and a curb weight of 3,825 pounds, this sleek four-door glides smoothly through the air, offering excellent fuel economy and reduced wind noise.
Inside, the C 300 Sedan impresses with room to stretch out:
- 41.7 inches of front legroom
- 36 inches of rear legroom
- 40 inches of front headroom
- 37.5 inches of rear headroom
- 56.3 inches of front shoulder room
- 55.6 inches of rear shoulder room
If comfort and practicality are top priorities, the C 300 Sedan delivers on both fronts.
2023 Mercedes-Benz C 300 Cabriolet: Open-Air Luxury with Compact Appeal
For those who crave fresh air and sunshine on demand, the 2023 C 300 Convertible—also known as the C 300 Cabriolet—offers a stylish, top-down experience with plenty of Mercedes-Benz refinement. It comfortably seats four passengers and includes 8.8 cubic feet of trunk space—slightly less than the sedan due to the space required for the soft-top roof.
Exterior and Interior Dimensions
The Cabriolet is 184.5 inches long, 79.4 inches wide (with mirrors), and 55.3 inches tall. Though slightly shorter and lower than the sedan, it carries more weight, with a curb weight of 3,904 pounds and a higher coefficient of drag at 0.31. This makes it a bit less aerodynamic and efficient than its sedan counterpart—but undeniably more fun in the right weather.
Interior dimensions are slightly tighter but still luxurious:
- 42 inches of front legroom
- 32 inches of rear legroom
- 38.8 inches of front headroom
- 35.6 inches of rear headroom
- 54.8 inches of front shoulder room
- 47.8 inches of rear shoulder room
Should You Choose the C 300 Cabriolet or Sedan?
If you’re a current convertible driver looking for a little more space, better year-round comfort, and improved aerodynamic performance, the 2025 C 300 Sedan makes a strong case as your next upgrade. On the other hand, if you still prioritize the joy of open-top driving and compact luxury, the C 300 Cabriolet remains a refined and stylish choice, and we can help you find a pre-owned model at our dealership.
