AIR has engulfed the Mercedes-Benz E-Class Cabriolet in more ways than one. Naturally more of it enters the cabin roof down, but the way CO2 moves in and around this soft-top is also significant.

It fills the chambers of the suspension’s springs, which aim to provide the wafting ride comfort expected of an E-Class large car. It wafts from driver and passenger headrests, nicely warmed to keep necks from freezing on a cool day. And, of course, this Cabriolet can flip its lid in 20 seconds (via remote control on approach or at up to 50km/h) to let nature’s smells flood the four-seat cabin.

In Australia only the rear-wheel drive 2.0-litre turbo E300, and all-wheel drive 3.0-litre turbo E400 are available, both of which claim to be faster, more efficient and more dynamic than ever before.

Hopefully such claims aren’t a load of hot air.
