Mercedes E- Class – This convertible benefits from the generous size of its new platform. Compared with its predecessor, the car is 5.0 inches longer and 2.9 inches wider and rides on a 4.4-inch-longer wheelbase. The rear seats are more spacious than before; they also offer available heaters. In a way, this is the first real E-class convertible since the W124 of the early and mid-1990s. That car was replaced by the CLK, which had far more in common with the smaller C-class. The outgoing E-class coupe and cabriolet continued that approach, sharing their track and wheelbase dimensions with the C. The new model, like the new 2018 E-class coupe, is based on the E-class sedan—for real. And that certainly helps to differentiate it from the C-class cabriolet. The E-class convertible’s power-operated fabric top is heavily padded, has interior roof lighting, and comes in four colors: red, black, dark blue, and dark brown. The windshield frame is finished in polished or matte aluminum, depending on the trim. Judging from our prototype ride, it will be virtually impossible to tell the cabriolet from a coupe from the inside when the top is up.
