Drop-top, V8, AMG performance; three words that can get anyone's heart racing. Mercedes has combined them, with the uber-luxury interior of the S-class and delivered the 2018 Mercedes-Benz AMG S63 Cabriolet 4MATIC+. The name is certainly a mouthful, but so is the list of comfort and safety features the Mercedes has crammed into the vehicle. The striking front grille, the redesigned bumpers, and OLED headlights give the car a fresh new look and stand out with its distinct sleek curves, with design cues from the Maybach Concept Cabriolet.

The 4-seater 2-door Cabriolet comes at a steep starting price of $179,500. The old 5.5-liter V8 engine has been replacing by a smaller, higher revving 4.0 liter V8 by AMG. Even with the more efficiency-focused engine, the power has been bumped up to 603 bhp. The new engine feels more responsive and has a jaw-dropping acceleration of 3.1 seconds 0-60.

This niche category may have very few contenders, but the competition is fierce. The open-top GT from Aston Martin, 2018 DB11 Volante, and the convertible version of BMW's formidable M6, put up a strong fight against the German Cabriolet. The DB11 Volante is a sharp and nimble GT cruiser, which borrows an AMG V8 engine, while the 2018 BMW M6 convertible is a rear wheel drive car, which is fast, yet practical.

Features

The top-drop AMG cab comes in two variants, the V8 powered S63 AMG Cabriolet and the monstrous 6.0 liter V12 powered S65 AMG Cabriolet. While AMG has replaced the 5.5 liter V8 from the 2017 model, with a smaller, more efficient 4.0 liter engine in the S63, It generates 26 more horsepower at 603 bhp. This places it closer to the crushingly expensive S65, which makes 621 bhp. AMG has also replaced the slow and clunky wet-clutch 7 speed transmission from 2017 transmission with an exponentially quicker multi-clutch 9-speed transmission.

However, the V8 powered younger brother has much better acceleration with a 0-60mph time of 3.1 seconds, compared to the S65, which takes 3.9 seconds.

We recommend

If you're looking for the ultimate S-class luxury with the power of an AMG engine in a drop-top body style, S63 is the perfect car for you. But, if you're willing to splurge, Mercedes exceeds all expectations with the lavish powerful beast, the S65 Cabriolet, at a steeper price of $250,900.

"Be prepared for the S63 to catapult forward as its four tires claw the pavement" - Car and Driver

 

Engine and Transmission

AMG being the performance racing division of Mercedes-Benz adheres to the One Man, One Engine philosophy. The handcrafted 4.0-liter Bi-turbo 8-cylinder engine produces 603 horses and 664 lb-ft torque, directed to all four wheels with the help of Mercedes 4MATIC+ system. The twin parallel turbochargers produce virtually zero turbo lag and pressure losses so that you get immediate power response even at low rpm.

The new quicker 9-speed multi-clutch transmission has a greater spread in lieu of the 2017 7-speed transmission. The top gear has been made taller for better fuel efficiency and employs a clutch coupler, eliminating the use of a torque converter and resulting in improved throttle response.

Compared to that, its British cousin, the Aston Martin DB11 Volante borrows the V8 engine from the German Cabriolet but re-tuned to get the distinct Aston Martin character. At the base price of $201,800, the Volante produces only 503 bhp. But since it weighs about a 1000 lbs less than the S63 Cab and looks absolutely captivating, the horsepower feels like an insignificant number.

The BMW M6 convertible is also a lower priced contender to the S63 Cab, at a much lower price of $122,300. It is turbocharged 4.4 liter V8 produces 552 bhp and propels it to 60mph in 4.3 seconds.

Acceleration

Even though the S63 Cabriolet weighs almost 5000 lbs, its acceleration is mind-boggling. It can get to 60mph in a mere 3.1 seconds from a standstill and completes the quarter mile in 11.4 seconds.

In comparison to the Merc, the DB11 Volante and M6 convertible are leagues behind, with a 0-60 time of 3.7 and 4.3 seconds respectively.

Ride and Handling

With the quiet mode on the active exhausts and the suspension in soft mode, the S-class feels like a lush and opulent ride with all the comforts and features of a premium luxury AMG. But when the track mode is switched on, the sleeping V8 awakens with a roar. The suspensions stiffen and the seat can be adjusted for optimum lumbar support in the corners. Driving with the roof down is an absolute bliss because of the expletive exhaust note as cracks tumble from the quad exhaust.

Braking

To stop the car, AMG has given the S63 Cab rigid 6-piston calipers in the front with compound perforated and slotted 15.4-inch discs. For higher brake endurance, the track-focused AMG ceramic compound brakes are a race-proven optional extra. The stopping distance for the 4975 lb car from 70mph in just 160ft and can sustain forces of up to 0.93g.

Comparatively, both the DB11 Volante and M6 convertible have a much lower curb weight, which translates to a better and shorter stopping distance.

Fuel Economy

The Convertible Mercedes claims an adequate Combined/city/highway mileage of 18/15/24 mpg, but subsequent tests have shown economy as low as 14 mpg. The taller top gear and shorter first gear improves the overall engine efficiency and results in a better economy compared to 2017 model.

The Economy of the S63 Cabriolet is quite better compared to the DB11 Volante at 17/15/21 mpg and the M6 convertible with 16/14/20 mpg fuel economy.

Seating and Comfort

Draped in sumptuous leather, the lavish interior of the S63 Cab exudes luxury and extravagance. The 12-way adjustable memory seats can be customized precisely for the ultimate driving experience. The adjustable lumbar support and active side bolsters called the Magic Body Control, which can be set to increase support while cornering to prevent lateral movement. There are six massage options, worthy of being compared to a high-end spa. The AIRSCARF neck-level heating system with 3 stage temperature controls keeps you snug, even when cruising with the top down.

As a part of the elite S-class, the Cabriolet comes equipped with the Mercedes signature Air Balance fragrance system, which diffuses the fragrance through the air vents at regular intervals. Additionally, heated steering, front and rear seats are standard.

Infotainment System

The infotainment systems in the S63 Cabriolet outshines the competition by a large margin.

It is entirely customizable, intuitive and easy-access for the driver via a touchpad controller and touch controls on the steering. The user can choose between a number of instrumentation styles which show a multitude of information about the vehicle based on the selected driving mode of the AMG DYNAMIC SELECT.

Cargo Volume

On the other hand, the M6 convertible has a relatively larger trunk space at 10.6cu ft with the roof down and 16.2cu ft with the roof up. Even the DB11 Volante has a larger storage space of 10cu ft.

Dimensions and Weight

The S63 Cabriolet is huge like a yacht. It weighs close to 5000 lbs and is more than 16.5 feet long. Despite the looks, it feels nimble and agile. The new Panamericana grille with the vertical slats adds to the aggressive looks. It can be optioned with either a night package or a chrome package for darkened or chrome accents. The convertible roof is a liberally padded cloth top, which takes 20 seconds to fold even while driving at a speed of 37 mph.

Competition

Aston Martin DB11 Volante

The British convertible is widely regarded as the pinnacle of design and performance. It is a head turner and the brutal exhaust note rivals even the loudest Italian beasts. It's improved structural rigidity and handles much better than the S63 Cab. The Aston Martin engineers have managed to keep a decent trunk space even with the roof folded down. Although it has as amusingly small rear leg room compared to the S63 Cab, The DB11 Volante is a proper long-distance GT cruiser with perfect proportions, worthy of the steeper price tag.

BMW M6 Convertible

The M6 is a great convertible by BMW M division which, akin to the AMG, is the Motorsport division of BMW. At a significantly lower price, the BMW has presented a daunting contender to the S63 AMG Cabriolet. As typical of any M-car, the, M6 inherits the DNA of delivering sheer driving pleasure. The M6 convertible is highly practical and fun to kick out the rear end around corners. The comfort features may not rival the plush interior of the Merc, but the price difference can justify the lack thereof.

Final Verdict

The 2018 Mercedes-Benz AMG S63 Cabriolet ousts its rivals with better performance, even better than the S65, and state-of-the-art features. The interior is futuristic and functional. The roaring twin-turbocharged V8 delivers power in an instant, while the plush leather seats keep you snug and comfortable. The mammoth size has an imposing presence on the streets, yet the car feels agile and fun to drive. The S63 Cabriolet is the best 4-seater luxury convertible that you can buy.
