Mercedes recently unveiled an all-new C-Class Sedan, which arrives sporting an all-four-cylinder engine lineup. We know other body styles will arrive soon, including a previously-spied wagon variant that likely will not arrive in the United States. Though we won't get the practical C-Class longroof in the US market, we should get the next-generation Mercedes-Benz C-Class Convertible. This is the first time we've spotted the C-Class Convertible out testing, so there's a lot to talk about here.

The final design is still heavily camouflaged, but this test mule gives away several important styling features. We aren't surprised to see the front end looks pretty similar to the sedan. The headlight shape reminds us of the CLA, but that could just be the camouflage tricking our eyes.

At the back, it's impossible to say how close the convertible will be to the sedan since these taillights do not look like production units. The drop-top C-Class will clearly retain its softtop layout with four seats, and the interior should look similar but not identical to the latest C-Class Sedan. This means you can expect to see the 11.9-inch touchscreen in the dash, combined with a 12.3-inch digital instrument cluster.

Under the hood, a base C300 model should produce 255 horsepower and 295 lb-ft from a 2.0-liter turbocharged four-cylinder engine with mild-hybrid assist. Future AMG models should add more power with a hybrid system.

Previous rumors suggested Mercedes could cut several models from its lineup, including the C-Class Coupe and Convertible. We can't speak for the coupe, but these spy shots clearly prove the convertible isn't dead yet. Mercedes currently has the most expansive convertible lineup in the industry with the outgoing C-Class, E-Class, S-Class, SL, and GT Roadster. The S-Class and GT Roadster won't receive new generations but the next-generation SL is coming soon and the E-Class was recently facelifted. Mercedes wants to keep the convertible alive at all price points, and we're glad to have them.
