Mercedes-AMG launches 4-seater S 63 4MATIC Cabriolet

Article by Christian Andrei, on September 2, 2015

Mercedes-Benz is offering what can only be described as the dream car for true automobile fans – the S 63 4MATIC Cabriolet. This marks the first time in the brand’s 48-year history that it is offering a four-seater Cabriolet in the S-Class segment. This newest product is an appealing choice for those who are looking for luxury and performance. Traveling can be done in style for the driver and as many as three passengers.

The performance figures are amazing. It is powered by a 5.5-litre V8 biturbo engine that delivers 430 kW (585 hp) and it has a peak torque of 900 Nm. It comes with AMG Performance 4MATIC all-wheel drive with rear-biased torque split as standard, allowing the vehicle to accelerate from a standstill to 100 km/h in 3.9 seconds. Deceleration is optimized with the use of a high-performance composite brake system.

This vehicle offers a superior and dynamic performance due to its highly rigid bodyshell structure that features innovations like the luggage compartment bulkhead built using magnesium. A convertible’s design is typically heavier but the automaker compensated by using a lightweight lithium-ion battery.

It also has been equipped with AMG light-alloy wheels built with a highly advanced forging process as well as with the weight-optimised AMG high-performance composite brake system. Aluminium is what makes up big parts of the shell and the front section as well as the vehicle's rear end.

Interior Design

The interior of the S 63 Cabriolet is luxurious. The instrument panel uses a wrap-around design that makes it appear as if it has seamlessly transitioned into doors. It uses the best materials and the finest workmanship, combined with a design that’s sporty and exclusive.

Lateral support for the driver and front passenger is at the optimum level with its new AMG sports seats that feature electrical adjustment, memory function and seat heating.

Controling the vehicle is easy with the three-spoke sports steering wheel with its characteristically contoured rim and perforated leather in the grip area.

When changing gear, reaction time is reduced by the aluminium shift paddles. It also improves dynamism. The look can’t be complete without the AMG signature high-resolution TFT colour display as an instrument cluster with two animated round dials.

Some of its other distinctive features are the AMG-specific lettering and the needles in red/silver, its start-up display, the AMG logo in the speedometer with 330 km/h scale and the "V8 BITURBO" lettering in the rev counter.

Powertrain

The AMG 5.5-litre V8 biturbo engine is still one of the most efficient series-made V8 engines in the world, considering its maximum output, torque and fuel use.

The AMG eight-cylinder engine delivers 430 kW (585 hp) and 900 Newton metres of torque, which means that it complies with the highest of standards. It also offers the most impressive performance. The S 63 Cabriolet is capable of moving from zero to 100 km/h in 3.9 seconds and reaching an electronically limited top speed of 250 km/h.

This two-door model is the most fuel-efficient model in its competitive segment with a NEDC fuel consumption rating of 10.4 litres for every 100 kilometres.

This only proves that a vehicle can offer the best in performance, efficiency, and environmental compatibility. In addition, the engine sound of the S 63 Cabriolet can be adapted according to the driver’s performances, ranging from emotional and sporty to something more subtle for long trips. The exhaust system features automatic logic-controlled exhaust flaps in both of its rear silencers. 

The sound produced by the eight-cylinder biturbo engine is more understated when the transmission is in "C" (Controlled Efficiency) mode as the flaps stay mostly closed. When the vehicle is in "S" (Sport) and "M" (Manual) modes, the exhaust flaps open earlier and more spontaneously, particularly if the driver has a dynamic driving style.

The result is a signature AMG engine sound that’s emotional. It is equipped with the AMG SPEEDSHIFT MCT 7-speed sports transmission that complements the V8 biturbo engine perfectly. This transmission, which is used only by AMG, offers the best agility and dynamics. Drivers can customize the set-up, depending on how they drive.

It comes in three modes: "C" (Controlled Efficiency), "S" (Sport) and "M" (Manual). The ECO start/stop function is a standard feature and works in transmission mode "C". The S 63 Cabriolet is offered with two versions: (1) the rear-wheel drive (as RHD version only); and (2) the performance-oriented AMG 4MATIC all-wheel drive (as LHD version).

The medley of S-Class Cabriolet and 4MATIC is exclusive to the AMG variant. With this drive, about 33% of the engine torque is distributed to the front axle while 67% goes to the rear axle. The signature AMG high driving dynamics and extreme driving pleasure are made possible with the rear-biased power distribution.

It boosts acceleration in all kinds of driving situations, which includes from a standing start. In addition, the all-wheel drive improves driving safety on wet, slippery, wintry surfaces.

Press Release

The new Mercedes-AMG S 63 4MATIC Cabriolet

Mercedes-Benz is presenting a superlative dream car in the guise of the S 63 4MATIC Cabriolet. For the first time in its 48-year history, Mercedes‑Benz's sports car and high-performance brand is offering a four-seater Cabriolet in the S-Class segment, adding to its product portfolio an attractive alternative for automobile enthusiasts with a penchant for performance and luxury.

The new model also offers its driver and up to three passengers space to travel in style. Its high-calibre statistics: 5.5-litre V8 biturbo engine with an output of 430 kW (585 hp) and peak torque of 900 Nm, AMG Performance 4MATIC all-wheel drive with rear-biased torque split as standard, acceleration from 0 to 100 km/h in 3.9 seconds and a high-performance composite brake system for optimum deceleration.

High-performance technology coupled with expressive exterior and interior design: It is immediately apparent that the new S 63 4MATIC Cabriolet is built by car enthusiasts for car enthusiasts. "The new S 63 Cabriolet is another fascinating AMG dream car from Affalterbach", says Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH. "The new model demonstrates in impressive style that we are keeping our foot firmly on the gas in 2015. We are continuing our model initiative with a vengeance - in all market segments."

AMG Lightweight Performance

The basis for the vehicle's superior and dynamic character is provided by the particularly rigid bodyshell structure featuring innovative solutions such as the luggage compartment bulkhead made of magnesium.

The increase in weight which is inherent to the design of a convertible has been limited by the use of a lightweight lithium-ion battery, AMG light-alloy wheels produced by means of a sophisticated forging process and the weight-optimised AMG high-performance composite brake system. In addition, large parts of the shell and the front section are made of aluminium, as is the vehicle's rear end.

AMG 5.5-litre V8 biturbo engine: superior and efficient

In terms of maximum output, torque and fuel consumption, the AMG 5.5-litre V8 biturbo engine remains one of the most efficient series-produced V8 engines in the world. With an output of 430 kW (585 hp) and 900 Newton metres of torque, the AMG eight-cylinder engine meets the very highest standards. And the same goes for its performance: the S 63 Cabriolet accelerates from 0 to 100 km/h in 3.9 seconds and has a top speed of 250 km/h (electronically limited).

NEDC fuel consumption of 10.4 litres per 100 kilometres makes the two-door model the most fuel-efficient model in its competitive segment. This just goes to show that performance, efficiency and environmental compatibility need not be mutually exclusive aims.

Exhaust system with automatic exhaust flaps

The S 63 Cabriolet also adapts to the driver's individual wishes in terms of its engine sound – from emotional and sporty to a more restrained alternative suitable for long journeys. The exhaust system has automatic logic-controlled exhaust flaps in both rear silencers. When the transmission is in "C" (Controlled Efficiency) mode, the flaps remain closed in most situations, in which case the eight-cylinder biturbo engine's sound is more understated. In "S" (Sport) and "M" (Manual) modes, the exhaust flaps open earlier and more spontaneously, especially if the driver prefers a dynamic driving style. This results in an emotional, signature AMG engine sound.

"One man, one engine": a tradition of hand-built excellence

The biturbo eight-cylinder engine of the S 63 Cabriolet is fitted by hand in the hand-finishing section of AMG's production plant in Affalterbach. Highly qualified engine fitters assemble the engines according to the strictest quality standards based on the "one man, one engine" philosophy. Apart from serving as an AMG hallmark confirming superlative precision and production quality, the AMG engine plate bearing the engine technician's signature also alludes to the peerless DNA of Mercedes-Benz's sports car and high-performance brand.

Individuality: AMG SPEEDSHIFT MCT 7-speed sports transmission

The AMG SPEEDSHIFT MCT 7-speed sports transmission combines perfectly with the V8 biturbo engine. Maximum agility and exciting dynamics are the two key strengths of this transmission, which is used exclusively at AMG. Drivers can configure their own personal set-up, depending on their driving style. There are three modes to choose from: "C" (Controlled Efficiency), "S" (Sport) and "M" (Manual). The ECO start/stop function features as standard and is activated in transmission mode "C".

Performance-oriented AMG 4MATIC all-wheel drive

There are two variants of the S 63 Cabriolet available: with rear-wheel drive (as RHD version only) or with the performance-oriented AMG 4MATIC all-wheel drive (as LHD version). The combination of S-Class Cabriolet and 4MATIC is exclusive to the AMG variant. The drive distributes 33 percent of the engine torque to the front axle and 67 percent to the rear axle. This rear-biased power distribution provides for the signature AMG high driving dynamics and superlative driving enjoyment, and improves acceleration in all driving situations, including from a standing start. The all-wheel drive also enhances driving safety on wet or wintry road surfaces.

AIRMATIC air suspension

The AMG specialists have also pulled out all the stops when it comes to the suspension: The S 63 Cabriolet comes with the AIRMATIC full-support air suspension featuring the adaptive damping system ADS PLUS, which can be preset to "Sport" or "Comfort". At the touch of a button, the special configurations of these two programmes enable outstanding agility and dynamics or unlimited comfort on long journeys and smooth cruising at low speeds.

Specific front axle kinematics – including a higher camber, a larger anti-roll bar and a stiffer subframe carrier on the rear axle – have also been developed for the Cabriolet. The AMG-specific elastokinematics and parameterisation of the continuously variable damper control, the lower air volume of the air suspension system and the progressive piston geometry nip unpleasant rolling and pitching in the bud.

It is also possible to raise the vehicle's level by 30 millimetres on poor surfaces. The chassis is lowered again automatically in "Sport" mode and from a speed of 120 km/h in "Controlled Efficiency" mode.

Systematic lightweight construction: AMG forged wheels as standard

The S 63 Cabriolet is equipped with forged AMG light-alloy wheels as standard. This forged design provides for extremely strong and particularly light wheels. The resultant lower unsprung masses give rise to advantages in terms of handling and spring/damper element response. In the standard specification, the S 63 Cabriolet is fitted with multi-spoke forged wheels painted in titanium grey with a high-sheen finish – 8.5 x 19 at the front and 9.5 x 19 at the rear, with 255/45 R 19 and 285/40 R 19 tyres respectively. Forged wheels are available as optional extras from the AMG Performance Studio, in size 8.5 x 20 at the front and 9.5 x 20 at the rear, fitted with tyres in size 255/40 R 20 and 285/35 R 20 respectively.

Optional AMG high-performance ceramic composite brake system

Short stopping distances and rapid deceleration are a given for the S 63 Cabriolet, which is equipped with a weight-optimised, fade-resistant high-performance composite brake system. A ceramic high-performance composite brake system is available as an option. The design, which is more than 20 percent lighter, ensures lower unsprung masses as well as enhanced driving dynamics, agility and ride comfort.

Design as an expression of sportiness and performance

The S 63 Cabriolet also boasts exciting looks to emphasise its sporty performance: The design is a stage for the exciting technology at the heart of the new dream car. Numerous exquisitely designed aerodynamic elements underscore the outstanding driving dynamics: the front end is dominated by the three-dimensional "twin-blade" radiator grille in silver chrome. Under the radiator grille is the "A-wing": this three-dimensional aerodynamic feature is painted in the body colour and sports the stylised "A" that is a hallmark of AMG vehicles. Large, black flics surround the outer cooling air intakes. Down below, the front splitter in silver chrome optimises the flow of air to the cooling modules. It also makes the vehicle appear closer to the road.

A similar effect is created by the side sill panels with their high-quality, three-dimensional inserts in silver chrome. Together with the lower feature line, these inserts make the S 63 Cabriolet exude dynamism even when it is at a standstill.

At the rear, the diffuser insert in high-gloss black also catches the eye straight away. The lower trim element in silver chrome is reminiscent of the A-wing at the front and provides an effective contrast. The two chromed twin tailpipes of the exhaust system with sports flaps are perfectly integrated into the diffuser insert.

Interior: beguiling luxury and sporty exclusivity

Opening the door reveals the beguilingly luxurious interior of the S 63 Cabriolet: the instrument panel almost seamlessly transitions into the doors in a wrap-around design. High-quality materials and fine workmanship are combined with a sporty, exclusive design idiom. The newly developed AMG sports seats with electrical adjustment, Memory function and seat heating offer the driver and front passenger optimum lateral support.

The three-spoke sports steering wheel with its distinctively contoured rim and perforated leather in the grip area allows perfect vehicle control. Aluminium shift paddles shorten the reaction time when changing gear and enhance dynamism. Another feature displaying the hallmark AMG look is the high-resolution TFT colour display as an instrument cluster with two animated round dials. In addition to the AMG-specific lettering and the needles in red/silver, further distinctive design features include the start-up display, the AMG logo in the speedometer with 330 km/h scale and the "V8 BITURBO" lettering in the rev counter.

World premiere in 2015 and market launch in 2016

The S 63 Cabriolet will have its world premiere at the Frankfurt International Motor Show. It will go on sale in December, and the market launch will begin in the spring of 2016.
