As with its predecessor, the new open top can also be optioned with Mercedes-Benz’s Aircap draught-mitigating system incorporated within the upper section of the windscreen header rail and the Airscarf neck heating ventilation system integrated into the front seat backs.
The larger footprint translates to increased interior accommodation, making the new E-Class Cabriolet a proper four-seater; headroom is up by 15mm up front and 6mm at the rear, shoulder room is increased by 50mm at the front and 14mm at the rear and elbow room grows by 38mm front and 20mm rear. The largest increase in interior space, though, is reserved for rear seat legroom, which is up by 102mm at a claimed 866mm.
Among the occupant safety measures offered by the new Mercedes-Benz model are five standard fit airbags, including a knee airbag for the driver, as well as four optional airbags, including side airbags in the rear. Further protection is provided by two sturdy beams integrated into the rear bulkhead. They are pyrotechnically fired out through the rear trim panel when sensors detect a possible rollover to create added survival space.
The E-Class Cabriolet is planned to be offered with the same engine line-up as the latest E-Class Coupé, alongside which it is produced at Mercedes-Benz’s plant in Bremen, Germany, with three petrols and a single diesel powerplant ranging in power from 181bhp to 328bhp.
The petrol line-up starts with E 200 Cabriolet powered by a turbocharged 2.0-litre four-cylinder engine with 181bhp. It is joined by the E 300 Cabriolet running the same turbocharged 2.0-litre four-cylinder as the E 200 Cabriolet tuned to a 242bhp. Above it sits the E 400 4Matic Cabriolet, which uses a twin-turbocharged 3.0-litre V6 engine delivering 328bhp.
The sole diesel in the initial UK line-up, the E 220 d Cabriolet, runs Mercedes-Benz‘s newly developed turbocharged 2.0-litre four-cylinder diesel engine with 191bhp.
All models come fitted as standard with Mercedes-Benz’s nine-speed automatic gearbox. The E 220 d Cabriolet and E 300 Cabriolet are rear-wheel drive, while the E400 4Matic, as its name suggests, comes as standard with Mercedes’ four-wheel drive system, which provides a nominal 45% front, 55% rear apportioning of drive.
As with the latest E-Class Coupé, the E-Class Cabriolet's suspension is lowered by 15mm over that of the E-Class Saloon and comes in combination with wheels range in size from 17 to 20in depending on the engine and styling package. Buyers can choose between three different suspension set-ups: a base steel-sprung Direct Control system, a steel-sprung Dynamic Body Control system with adaptive damping and an Air Body Control system with multi-chamber air springs.
