The Mercedes-Benz S-Class has long been the benchmark in the luxury sedan segment as the measurement of excellence. Audi and BMW specifically have taken aim at the S-Class with their newest A8 and 7-Series offerings, and despite all being excellent cars,  none quite convey the same flagship feeling that the S-Class sedan does.

Where the S-Class sedan has direct competition from several other brands, there is one model in the S-Class family that stands alone at the top of the ultra-luxury, four-seat convertible segment – the Mercedes-Benz AMG S63 Cabriolet.

Building luxury convertibles is a task that Mercedes-Benz has excelled at for years. In the current lineup, there are no fewer than six models available in drop-top form, from the more pedestrian C-Class Cabriolet all the way up to the performance-oriented AMG GT convertible.

Sitting at the top of the Mercedes-Benz convertible family tree, the 2019 S-Class Cabriolet is the biggest and also the most expensive of the bunch. Add the signature AMG treatment, and you have one of the rarest and most beautiful vehicles in the Mercedes-Benz lineup.

The yacht-like AMG S63 Cabriolet gets Mercedes-AMG’s awesome hand-built, twin-turbocharged 4.0-liter V8, which makes 603 horsepower and 664lb-ft of torque. Power is delivered to all four wheels via Mercedes’ excellent 4MATIC+ all-wheel drive system and the AMG SPEEDSHIFT 9-speed transmission.

Putting the AMG S63 Cabriolet into Sport+ mode and nailing the go-pedal to the floor rockets the car to 60 mph in just 3.8 seconds, all while serenading the occupants with the sweet songs of the legendary AMG V8 exhaust note.

Ride quality in the AMG S63 Cabriolet is excellent as one would expect from a car wearing the S-class badge thanks to adaptive dampers and driver-selectable drive modes to adjust varying levels of sport and comfort.

S-Class buyers expect opulence in every corner, and the Cabriolet version delivers that experience in every way. The attention to detail with the leatherwork and woodwork is incredible. Our tester featured the eye-popping $3,250 designo Porcelain and Deep Sea Blue Nappa leather interior, with $1,300 designo Magnolia “Flowing Lines” wood treatment. Both make the cabin an absolutely beautiful place to be, but I’m curious how well that light color leather will hold up over time.

The sculpted front seats and the beautiful dashboard in the S63 Cabriolet are direct carryovers from the S-class sedan. Front seats include massaging functions in the seemingly infinitely adjustable seats, along with dynamic bolsters and massage features. The dashboard features a fantastic dual-pane digital instrument cluster and infotainment system which is extremely easy to read.

Buttons for feature operations are plentiful throughout, making radio and AC controls fairly simple to use. I still feel that the radio/infotainment features could use some improvements to the UI/UX to make access to features like sound control and media control more streamlined.

Rear seats in the S63 Cabriolet look tight at first glance, but we managed to fit two 6’0″+ adults in the rear seats with the top down with comfort, thanks to the strategically placed knee cutouts on the backs of the seats. We wouldn’t want to put passengers that tall in the back for any long trips, and it might get a bit claustrophobic for some with the top up.

Our tester S63 Cabrio also featured the $6400 Burmester surround-sound audio system, which in our opinion is a must-have option. The speaker grilles are works of art themselves, but the sound quality of the stereo is the best I’ve ever heard in any vehicle. Sound quality is retained even when the convertible top is dropped.

Of course, the one thing we haven’t talked about yet is the AMG S63 Cabriolet’s price. All this opulence doesn’t come cheap, with the car starting at a mind melting $180,100. Start adding options and that price keeps going up. Our tester’s major options were $3,950 Cashmere White Magno matte paint, $2,260 Night View Assist Plus, $1,750 Swarovski Crystal Headlamp Accents, and the $1,990 Warmth and Comfort package.

All said and done, the all-in price of our tester was $206,645. That’s a huge pricetag, but consider the only vehicle remotely close to the AMG S63 Cabriolet in terms of performance and luxury is the Bentley Continental V8 Convertible. The Bentley starts at $218,400 before options, and can easily head towards the $300k mark. The S63 Cabriolet still delivers more power, more technology, and arguably a better interior than the Bentley, at a lower price.

For those select few who have the means to buy the Mercedes-Benz AMG S63 Cabriolet, rest assure that you are exchanging your dollars for simply the best 4-seat convertible you can buy today.
