A coupe and a convertible usually share the same shape: two doors and a sporty profile. The difference is the roof. A coupe's roof is fixed; a convertible's folds away behind the seats. That one change affects weight, quiet, trunk space, and price.
The difference in one line.
Take a coupe, remove the fixed roof, strengthen the body to make up for it, and add a roof that folds: that is a convertible. Most brands build both from the same car, such as the Mercedes-Benz CLE Coupe and CLE Cabriolet, the BMW 4 Series Coupe and Convertible, the Porsche 911 Coupe and Cabriolet, and the Ford Mustang in both styles.
Kinds of convertible tops.
- Soft top: an insulated fabric roof. Lighter, folds into less space, and today's multi-layer tops are far quieter than older ones. Most Mercedes-Benz, BMW, and Porsche convertibles use one.
- Retractable hardtop: rigid roof panels that fold into the trunk. Quieter and more secure, but heavier, and they take more trunk space when stowed.
- Targa: a removable roof panel over the front seats with a fixed rear section, like the Chevrolet Corvette's removable roof and the Porsche 911 Targa.
- Roadster: a two-seat convertible, like the Mercedes-AMG SL and the Mazda MX-5 Miata.
What a convertible gives up.
- Weight: the extra bracing and the roof mechanism add weight, so a convertible is usually a little slower than the matching coupe.
- Quiet: even the best soft tops let in more wind and road noise at highway speed.
- Trunk space: the folded roof lives in the trunk, so luggage room drops when the top is down.
- Price: the convertible version typically costs several thousand dollars more than the coupe, and insurance can run higher.
- Security: a fabric roof is easier to cut, so keep valuables out of sight.
What a coupe gives up.
- Open-air driving, which is the whole point for many buyers.
- In some models, the convertible holds its value better in sunny markets, where demand is steadier.
Which one fits.
Choose the coupe if you drive long highway miles, want the quietest cabin and the most trunk, or want the sharpest version of the car. Choose the convertible if open-air weekends matter more than those trade-offs; modern convertibles are comfortable enough to drive every day.

Quick answers.
Is a cabriolet different from a convertible?
No. Cabriolet is the European word for a convertible; Mercedes-Benz and Porsche use it, BMW and most American brands say convertible.
Can you drive a convertible in winter?
Yes. Modern soft tops are insulated and heated cabins handle cold weather well. Many convertibles add neck-level heating, such as Mercedes-Benz AIRSCARF, for top-down driving in cool weather.
Do convertibles leak?
A well-kept modern convertible should not. Seals age, so keep them clean, and have the dealership check them if you notice water or wind noise.
