A single design sketch shows a convertible with sleek lines, along with large wheels and tires. It bears a family resemblance to the all-new 2017 Mercedes-Benz C-Class Coupe.
The coupe is a companion to the Mercedes-Benz C-Class sedan and is longer and wider than its predecessor. It will arrive in U.S. showrooms in the spring.
Several powertrain options and a high-performance AMG version of the C-Class Cabriolet are expected.
Edmunds says: Convertible shoppers making long-range plans will want to check out the new C-Class Cabriolet when it hits showrooms later this year.
