Mercedes-Benz will have an incredibly strong showing at this year's Frankfurt Auto Show, and could potentially steal the show. Its AMG division will finally present the brand's halo hypercar, the phenomenal Project One, while the EQ A Concept will usher a new generation of Mercedes EVs to take on Tesla. Elsewhere, the facelifted S-Class family will be expanded with the reveal of the 2018 Coupe – but that won't be the only luxury grand-tourer on show this year.

The classy S-Class Cabriolet will be getting the same treatment as the Coupe, with a fresh new face, a new engine range and a suite of sophisticated tech lifted from the sedan for the updated 2018 model. Like the 2018 S-Class Coupe, the Cabriolet variant is powered by Mercedes' 4.0-liter, twin-turbo V8 mated to a nine-speed automatic transmission, churning out 463 horsepower and 516 pound-feet of torque. Unlike the Coupe, however, the Cabriolet is only available in rear-wheel drive, whereas the Coupe is being sold with 4Matic all-wheel drive as well. Sprint time is identical to the Coupe: 0-62 mph takes 4.5 seconds, before the Cabriolet tops out at an electronically limited 130 mph top speed.

Exterior changes from the Coupe have also been carried over. The 2018 S-Class Cabriolet adopts the AMG GT R's Panamericana grille, as well as OLED tail lamps, and redesigned headlights and front and rear bumpers. Updates specific to the Cabriolet like the Aircap wind deflector and Airscarf neck warmer have been carried over from the previous model. The S560 Cabriolet's interior has also been enhanced, featuring the familiar dual 12.3-inch touchscreen displays which have been updated for the 2018 model with Mercedes' COMMAND navigation system embedded into the instrument panel for a more streamlined look.

There's also a wealth of advanced driver assists that were first introduced in the S-Class sedan with semi-autonomous technology, including Active Distance Assist Distronic and Active Steering Assist as standard. Prices haven't been announced yet, but the 2018 S-Class Cabriolet will go on sale in the US mid-2018 alongside the Coupe.
