From 0 to 100 km/h (62.1 mph) in 4.7 seconds. The new Audi S5 Coupé* 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 a 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 coupé.
Strong heart: 3.0 V6 TFSI
The completely redesigned, turbocharged 3.0 TFSI engine for the Audi S5 Coupé* offers powerful performance: high power, ample torque, spontaneous response and a sonorous sound. All of that paired with a new level of efficiency.
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 Coupé consumes just 7.3 liters per 100 kilometers (32.2 US mpg) – a CO2 equivalent of 166 grams per kilometer (267.2 g/mi). Fuel consumption has dropped by five percent compared with the predecessor engine.
New combustion process: higher efficiency
The decisive success factor for the efficiency of the V6 3.0 TFSI is the new combustion process from Audi. It is based on what is known as the B-cycle, which is similar to the process used in the Audi A4 2.0 TFSI with 140 kW (190 hp)* and utilizes the high-pressure injection valves that are arranged centrally in the combustion chambers.
The shortened compression stroke of the updated combustion process enables the use of an engine process with a significantly higher geometric compression ratio in the V6 TFSI. Combined with a power stroke that, while normal, is longer relative to the compression stroke, this allows for more efficient combustion and increased engine efficiency.
This measure normally significantly reduces the fill of the cylinders, however, and the high compression ratio increases the engine’s tendency to knock, which significantly limits the maximum achievable output. The Audi valvelift system resolves this conflict between efficiency and output orientation. Under part load, it enables a very short intake aperture duration of 130 degrees of camshaft angle coupled with the early closure of the intake valve. At higher loads, the engine can switch to a camshaft contour with a longer aperture duration and greater intake valve lift, with which the engine achieves its maximum output.
Turbocharger: separate exhaust gas flows
The turbocharger, which replaces the mechanical compressor of the previous engine, operates according to the twin-scroll principle. The exhaust branches of the two cylinder banks run separately in the exhaust manifold and in the turbocharger housing, and only merge before the turbine wheel. This technology avoids undesirable interactions between the two gas columns, and it makes a major contribution toward early and powerful torque build-up.
The turbocharger is located within the 90-degree V of the cylinder banks. It normally sits on the outside next to the crankcase. Accordingly, the exhaust side is on the inner side of the cylinder heads and the intake side on the outer side. This layout enables compact construction and short gas flow paths with minimal flow losses – the 3.0 TFSI responds extremely spontaneously and directly.
Weight reduction: minus 14 kilograms (30.9 lb)
Thanks to a thorough redesign, the V6 TFSI has shed 14 kilograms (30.9 lb) and now weighs 172 kilograms (379.2 lb). Made with an aluminum alloy using the complex sand casting process, the cylinder crankcase features integrated, thin-walled cylinder liners of gray cast iron. In combination with the newly developed rings for the aluminum pistons, this reduces friction.
Another efficiency module is the thermal management system. The crankcase and the cylinder head have separate coolant circuits. After a cold start, the switchable water pump controls the flow of coolant through the engine so that the oil comes up to its operating temperature as quickly as possible. The exhaust manifold is integrated into the cylinder head and coolant circulates around it, which helps to heat up the engine quickly. When the engine is warm the system reduces the exhaust gas temperature, which reduces fuel consumption, particularly during sporty driving.
The drivetrain of the Audi S5 Coupé* 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. Its large number of gears makes it possible to operate the engine close to its ideal load point very frequently. Their lower gears have short, sporty ratios, while the upper gears are long to reduce revs and fuel consumption.
The torque-converter transmission is integrated into the engine’s thermal management system and is designed for start-stop operation (from 3 km/h (1.9 mph) residual speed). The driver can select the D, S or E mode and can use shift paddles on the steering wheel for manual gear changes. All commands are transmitted to the transmission electrically – by wire.
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). If the car is equipped with the optional systems predictive efficiency assistant and adaptive cruise control Stop&Go including traffic jam assist, coasting is managed in a very anticipatory manner.
Standard: quattro drive
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 Coupé*. During normal driving, its all-mechanical center differential directs 60 percent of the torque to the rear axle and 40 percent to the front. If slip occurs at one axle, most of the forces are rapidly redirected to the other axle – up to 85 percent to the front or up to 70 percent to the rear axle. These high locking figures enable a clearly defined torque distribution and precise interplay with control systems.
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. These interventions are made even if the driver does not press the accelerator pedal. The difference between propulsive forces at the wheels makes the car turn into the curve ever so slightly – making handling even more precise, agile and stable.
Wheel-selective torque control at the rear axle: the sport differential
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 latest generation of the differential is roughly one kilogram (2.2 lb) lighter.
During fast driving, the sport differential literally pushes the car into the curve, nipping understeer in the bud. A software function integrated into the central suspension control unit continuously computes the ideal torque split for dynamic driving. When turning into or accelerating in a curve, the majority of the torque is directed to the outside wheel, pushing the car into the curve. Before the rear end can break out, the car is stabilized and thus easily controlled. The control unit for the sport differential is tightly networked with Audi drive select so that the driver can influence the torque split.
Optional control: the S sport suspension
The Audi S5 Coupé features a newly developed S sport suspension with five-link suspensions front and rear. The axle principle enables optimal absorption of longitudinal and transverse forces. Its mounts are sporty-stiff in a lateral direction and supple and soft longitudinally. Together with the updated electromechanical power steering with direct steering ratios, the mounts lay the foundation for dynamic handling, good comfort and a high degree of stability. 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 Coupé. The driver can push a button to choose the default setting of the suspension in Audi drive select and thus call up the desired handling characteristics at any time. The variable S sport suspension works with newly developed CDC dampers (CDC = continuous damping control) with electromagnetically actuated valves in their pistons. They allow hydraulic fluid to flow faster or more slowly as required. A new actuation concept makes them very energy efficient. The central suspension control unit processes all sensor signals within milliseconds and controls each damper individually. Together with the wide range of the damper valves, this ensures a wide spectrum between a soft ride and firm handling.
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 Coupé 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.
Body and exterior
The new Audi S5 Coupé* spans a length of 4,692 millimeters (15.4 ft). It is 1,846 millimeters (6.1 ft) wide and 1,371 millimeters (4.5 ft) high. The long wheelbase of 2,764 millimeters (9.1 ft) emphasizes the dynamic silhouette of the two-door sports coupé.
The intelligent combination of materials makes the body very torsionally stiff, safe and lightweight. The new Audi S5 Coupé with standard quattro all-wheel drive weights 1,615 kilograms (3,560.5 lb), 60 kilograms (132.3 lb) less than the previous model.
Audi equips the new S5 Coupé standard with LED headlights. The lower edge of the wide and flat Singleframe extends much farther upward than in the previous model. The striking bumper is expressively shaped. The flat air inlet below is adorned by a matt aluminum silver trim strip and spans the entire width of the vehicle. The side air inlets have bold edges and honeycomb grilles in matt titanium black as well as vertical bars evoking the blades of a racing car. At the front end, the new Audi S5 Coupé 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 Coupé exhibits a characteristic, wave-shaped shoulder line. The sweeping line with pronounced bulges over the wheel arches is a visual cue to the quattro all-wheel drive. At the transition from the front wheel arch to the A-pillar, a three-dimensional trim element in matt aluminum silver with an integrated S5 logo underscores the supreme sportiness of the new Audi S5 Coupé. As with a racing car, the aluminum-look exterior mirrors are mounted on the top shoulders. Chrome inserts for the door handles and powerfully contoured sill trims in the body color with textured black sill top strips also contributed to the honed exterior.
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. Integrated into the boldly shaped rear bumper is a flat, black honeycomb grille. The matt twilight gray diffuser with vertical struts and a matt aluminum silver clasp frame the two dual chrome tailpipes.
The three-dimensional trim elements on the flanks, the radiator grille and the luggage compartment lid bear S5 logos with a red rhombus. The 11-shade color palette includes two new colors exclusive to the S model: Navarra blue and Misano red.
The new Audi S5 Coupé* also features cultivated sportiness in the interior. The clean design with its strong horizontal orientation makes the spaciously designed interior – which seats four – appear even larger. With a volume of 465 liters (16.4 cu ft) the luggage compartment of the S5 Coupé offers everyday practicality.
A broadly extended band of air vents, an elegant air conditioning panel and a large decorative surface define the instrument panel layout. The Audi MMI display welcomes the driver and passengers with a screen featuring the S5 logo. At night, LED light guides trace the contours of the doors and the center console – in 30 colors with the optional ambient light package. The illuminated door sill strips, the three-spoke sport leather steering wheel with multifunction plus and the chrome clasp on the tiptronic selector lever bear the S logo with a red rhombus (as do the welcome screens of the color DIS or Audi virtual cockpit and the MMI display.
Thanks to the vehicle’s excellent aeroacoustics, the interior noise level is exceptionally low. The workmanship quality is on the high level that distinguishes an Audi. As is typical for an S model, the color black dominates. For example on the headlining and the instrument panel. The decorative inlays provide elegant contrasts. They come standard in matt brushed aluminum, with options for carbon Atlas, gray natural oak and black piano finish.
The optional S sport seats have integrated head restraints, adjustable bolsters and a pneumatic massage function. Fine Nappa leather in the colors black, rotor gray or magma red with diamond pattern, contrasting stitching and an S badge is the standard upholstery.
Audi virtual cockpit
One highlight is the optional Audi virtual cockpit. It displays all key information in razor-sharp graphics on its 12.3-inch monitor. Views available to the driver include a sport mode centered around the tachometer.
Controls & displays, infotainment and Audi connect
In the new MMI operating system, the flat menu structure is based on that of today’s smartphones, including intelligent free-text search. It suggests various search results after just a few letters have been entered. In addition, user operation is possible from the multifunction steering wheel or by natural language voice control.
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 Coupé 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.
Leading role: driver assistance systems
The new Audi S5 Coupé* 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 Coupé as for the A5 Coupé.
The new Audi S5 Coupé* will be available on the European market from fall 2016. Its extensive list of standard equipment includes LED headlights, 18-inch cast aluminum wheels, an eight-speed tiptronic and quattro all-wheel drive.
