Are you looking to upgrade from your current convertible to a new sedan? Whether you’re swapping open-air freedom for year-round comfort or simply exploring the evolution of Mercedes-Benz style and performance, the team at Mercedes-Benz of Arrowhead in Peoria, AZ, is here to help. In this Mercedes-Benz C 300 Convertible and Sedan comparison, we’ll highlight essential differences in size, interior space, aerodynamics, and practicality. Whether you’re searching for the perfect C 300 Cabriolet or considering a spacious C 300 Sedan, this guide is your starting point.
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.
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:
If comfort and practicality are top priorities, the C 300 Sedan delivers on both fronts.
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.
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:
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.
