Like their coupe counterparts, 2018 brings a minor refresh for the Mercedes-AMG S63 and S65 cabriolets. What's new? Both variants of AMG's big two-door now feature a revised grille, which Mercedes calls an "AMG Panamericana grille" that will likely be used in future AMG models. This makes sense given it features on the AMG GT, which is considered the high-performance division's crown jewel. Other relevant exterior updates include larger front air ducts for better cooling, slightly revised front and rear bumpers, and some restyled chrome trim.

The interior is as uber luxurious as ever. There are some new leather upholstery color choices, but the most significant update is within the large infotainment screen. The COMAND system features two new high-resolution displays, each measuring in at 12.3 inches. Both can be controlled with steering wheel buttons that respond to hand gesture swiping motions. Also, and this couldn't have come soon enough, COMAND is now fully compatible with Apple CarPlay and Android Auto. Mercedes-AMG also updated both cabrios with Daimler's latest semi-autonomous tech, including Active Distance Assist Distronic and Active Steering Assist.

Under the hood, the AMG S63 retains its bi-turbo 4.0-liter V8, but it's been given a power boost for a new total of 603 hp and 664 lb-ft of torque, which is paired to nine-speed automatic. As for the AMG S65 cabrio, that luscious 6.0-liter V12 returns unchanged, delivering 621hp and 738 lb-ft of torque. Unlike the AMG S63, the AMG S65 comes with a seven-speed gearbox only. Why's that? Because it's rear-wheel-drive only, unlike the AMG S63, which features 4Matic all-wheel-drive. Exact pricing will be announced closer to the on sale date, which is due to begin sometime in the middle of next year.
