2017 Mercedes-AMG C63 vs 2017 Audi S5

Mercedes-AMG Press Release Highlights

Mercedes-AMG is setting a further landmark in the brand history: the new C63 Coupé is the next step on the way to yet more technical and visual distinctiveness. The far-reaching technical modifications are evident at first sight: strikingly flared front and rear wheel arches, an increased track width and larger wheels give the Coupé a muscular look while at the same time providing a basis for the highly agile longitudinal and lateral dynamics. The brand's typical "Driving Performance" is taken to new heights also with the C63 Coupé. The AMG 4.0-litre V8 bi-turbo engine with 350 kW (476 hp) or 375 kW (510 hp) is just as much a completely in-house development from Affalterbach as, for example, the sophisticated AMG RIDE CONTROL suspension with electronically controlled shock absorbers, the set-up of the AMG DYNAMIC SELECT transmission modes, the rear-axle limited-slip differential or the dynamic engine mounts. The C-Class is Mercedes-AMG's best-selling model series and forms the backbone of the company's success.

The Mercedes-AMG C63 Coupé already fascinates at first glance with its impressive proportions. The expressive exterior design differs significantly from the Mercedes-Benz model, which shares merely the same doors, roof and boot lid. The powerful 8-cylinder engine, together with the increased track width on the front and rear axles, calls for a redesigned front end and a model-specific rear assembly as well as new side walls. The extremely wide front section is characterized by large air inlets and precisely positioned flics. The low, arrow-shaped "twin blade" radiator grille with AMG lettering visually lowers the vehicle's center of gravity.
The C63 S Coupé accelerates from 0 to 100 km/h in 3.9 seconds, the C63 Coupé in 4.0 seconds. This makes the Coupé just a fraction faster than the Saloon - thanks to the wider tires and shorter-legged rear-axle ratios. The top speed is 250 km/h (electronically limited; 290 km/h with AMG Driver's Package). The 4.0-litre 8-cylinder bi-turbo engine is already used in the C63 Saloon and the C63 Estate. It is also installed in the GT sports car with dry sump lubrication. Characteristic feature: the two turbochargers are positioned not on the outside of the cylinder banks, but between them in the "V".

The typical V8 engine sound was likewise a key development goal. It was specially tailored to the Coupé. A model-specific exhaust system with flap technology is used as standard. It is automatically map-controlled depending on the AMG DYNAMIC SELECT transmission mode, the power demanded by the driver and the engine speed. The engine sound varies between discreet/suitable for long-distance driving and robust/emotively appealing. Optionally available is the Performance exhaust system, which allows the sound to be modulated at the press of a button.

The transmission plays a major part in the direct and sporty character of the new Mercedes-AMG C63 Coupé. The AMG SPEEDSHIFT MCT 7-speed sports transmission impresses with its tailor-made dynamics and high variability. Whether automatic or initiated by the driver using the steering wheel shift paddles, upshifts and downshifts are executed noticeably faster than in the previous model.

Unique in its segment, the C63 S Coupé - like the Saloon and the Estate - is equipped with dynamic engine mounts. These help to further resolve the conflicting aims of comfort and dynamic performance. These dynamic mounts are instantly and variably able to adapt their stiffness to the driving conditions and requirements. Soft engine mounts improve comfort, as they provide more effective decoupling of noise and vibration. However, handling and agility benefit from a generally stiffer mount set-up.
The fascinating agility and high cornering speed of the C63 Coupé are also thanks to the completely redesigned suspension. A four-link front suspension with radial, racing-style brake connections is used. Model-specific steering knuckles and a wider track allow greater lateral acceleration. The rear axle, too, was completely newly developed for the Coupé. The multi-link concept impresses with highly precise wheel control and increased stiffness. The AMG-specific rear axle carrier makes the increased track width possible. Other measures include AMG-specific wheel carriers, stiffer elastokinematic tuning and higher negative camber. With the AMG RIDE CONTROL suspension with adjustable damping, the customer can choose between maximum sportiness and excellent long-distance comfort in three stages at the press of a button. The difference between the comfortable and sporty suspension settings is also subjectively perceptible - depending on the particular driving situation.

For improved traction and vehicle dynamics, the C63 Coupé is provided with a mechanical rear-axle limited-slip differential, while the C63 S Coupé comes with an electronic rear-axle limited-slip differential. Both differentials reduce the slip on the inside wheel when cornering, without control interventions in the braking system. This allows the driver to accelerate out of corners earlier thanks to the improved traction. The car remains more stable when braking from high speeds, and the limited-slip differential also improves traction when moving off. The greatest benefit of the electronic rear-axle limited-slip differential - installed as standard on the C63 S - is the even more sensitive and faster control, which further raises the critical limit of drivability.
The driver is able to influence the characteristics of the C63 with four different AMG DYNAMIC SELECT transmission modes. The C63 S has an additional "Race" transmission mode. There is therefore scope for maximum individualization. The driver decides on the desired driving experience, from comfortable-economical to super-sporty, using a controller to the left of the touchpad. The driver can choose between various preconfigured transmission modes and an "Individual" mode that the driver can to a large extent personally configure.
The Coupé also offers a supreme level of safety. It comes as standard with the ATTENTION ASSIST drowsiness detection system and COLLISION PREVENTION ASSIST PLUS, which helps to prevent rear-end collisions. Many other optional assistance systems are available to increase both comfort and safety.

Audi Press Release Highlights

The new Audi S5 Coupe combines dramatic design with the performance of a sports car. Its newly developed, turbocharged V6 engine produces 260 kW (354 hp) and consumes just 7.3 liters of fuel per 100 km (32.2 US mpg). With an unladen weight of 1,615 kilograms (3,560.5 lb.), the car weighs 60 kilograms (132.3 lb.) less than the previous model. The precision-honed exterior design and the numerous S-specific details in the interior underscore the dynamic character of the Audi two-door sports Coupe.

Audi equips the new S5 Coupe standard with LED headlights. The lower edge of the wide and flat Single frame extends much farther upward than in the previous model. The striking bumper is expressively shaped. At the front end, the new Audi S5 Coupe expresses its independence with additional sporty details, such as the S-specific radiator grille in matt twilight gray with double slats in matt aluminum silver. When viewed from the side, the new Audi S5 Coupe exhibits a characteristic, wave-shaped shoulder line. The rear end sports slim LED rear lights with dynamic turn signals. A distinctive spoiler in the body color on the luggage compartment lid improves the aerodynamics.
The completely redesigned, turbocharged 3.0 TFSI engine for the Audi S5 Coupe offers powerful performance. From its 2,995 cc of displacement, the V6 TFSI produces 260 kW (354 hp), which is 15 kW (21 hp) more than the previous engine. A constant 500 Nm (368.8 lb-ft) (plus 60 Nm/44.3 lb-ft) of torque is available from a low 1,370 all the way to 4,500 rpm. In the NEDC, the new 3.0 TFSI in the S5 Coupe consumes just 7.3 liters per 100 kilometers (32.2 US mpg). Fuel consumption has dropped by five percent compared with the predecessor engine. The turbocharger is located within the 90-degree V of the cylinder banks. It normally sits on the outside next to the crankcase. From 0 to 100 km/h (62.1 mph) takes 4.7 seconds.

The drivetrain of the Audi S5 Coupe has also been completely updated. This also applies to the smooth, rapid and spontaneously shifting, eight-speed tiptronic. The layout of its gear sets and shifting elements results in low drag torques and thereby to a high efficiency level. The driver can select the D, S or E mode and can use shift paddles on the steering wheel for manual gear changes. As soon as the driver lifts off the accelerator at speeds between 55 and 160 km/h (34.2 and 99.4 mph), the transmission begins freewheeling mode if this will save fuel (exception: Mode S).

The Quattro permanent all-wheel drive system with its asymmetrically dynamic layout makes a major contribution toward sporty and stable handling of the new Audi S5 Coupe. During normal driving, its all-mechanical center differential directs 60 percent of the torque to the rear axle and 40 percent to the front. Wheel-selective torque control - an intelligent software function - complements the work of the Quattro drive system. In dynamic cornering, it applies minimal brake interventions at the wheels on the inside of the curve before they begin to spin. The optional sport differential provides for even more dynamic response when steering and accelerating. It distributes torque between the rear wheels via two superposition gears.
The Audi S5 Coupe features a newly developed S sport suspension with five-link suspensions front and rear. With their low weight, the new parts also reduce fuel consumption. Audi also offers optional dynamic steering, which adapts its steering ratio to the vehicle's speed and the steering angle.

As an alternative to the standard S sport suspension with highly sensitive monotube shock absorbers, Audi also offers a version with S-specific damper control for the new S5 Coupe. The variable S sport suspension works with newly developed CDC dampers (CDC = continuous damping control) with electromagnetically actuated valves in their pistons.

The brakes are dimensioned to be large. At the front wheels, the internally-vented discs are 350 mm (13.8 in) in diameter. They are gripped by black (or optionally red) painted six-piston fixed calipers with rhombus S logos. Electronic Stabilization Control (ESC) operates even more precisely and sensitively than in the previous model. The driver can choose to deactivate it partially or entirely over two stages.

The new S5 Coupe comes standard with 18-inch wheels in a five-spoke start design. The 245/40-series tires weigh less than 12 kilograms (26.5 lb.). A number of 19-inch wheels are available as options.
One highlight is the optional Audi virtual cockpit. It displays all key information in razor-sharp graphics on its 12.3-inch monitor. In the new MMI operating system, the flat menu structure is based on that of today's smartphones, including intelligent free-text search. MMI navigation plus with MMI touch and an 8.3-inch monitor top the infotainment range. MMI touch has a touchpad for zooming and scrolling and for entering characters. The system includes the Audi connect hardware component, which connects the new Audi S5 Coupe to the Internet via LTE. Passengers can freely surf and email with their mobile devices thanks to the integrated Wi-Fi hotspot with optional data packages. The driver can use the diverse online services from the Audi connect portfolio.

The optional Audi phone box with wireless charging connects smartphones to the on-board antenna via near-field coupling and simultaneously charges them inductively according to the Qi standard. The Audi smartphone interface brings Apple Car Play and Android Auto into the car. For discerning hi-fi fans, the Bang & Olufsen Sound System with new 3D sound is available.
The new Audi S5 Coupe is at the front of its segment with a wide range of driver assistance systems. The systems come from the full-size class; their intelligent interplay represents another step on the road to piloted driving. Audi offers the same systems for the S5 Coupe as for the A5 Coupe.
