Hot, throaty sound, exhilaratingly free-revving and brawny power – the five cylinder engines from Audi are legendary. 270 kW (367 hp) output and 465 Nm (343.0 lb ft) of torque – Audi presents the new RS 3 Sportback, the most powerful compact car in the premium segment.
With its powerful five cylinder, turbocharged engine, the five door model accelerates from 0 to 100 km/h (62.1 mph) in 4.3 seconds, and its top speed can be increased to 280 km/h (174.0 mph) upon request.
“There is a long tradition of five-cylinder engines at Audi,” says Prof. Dr. Ulrich Hackenberg, Board Member for Technical Development at AUDI AG. “In the 80s, they turned Audi into a sporty brand, both in motor sports and in production. The new Audi RS 3 Sportback features the latest generation of our 2.5 liter, five‑cylinder engine – the most powerful production engine in the modular transverse matrix.”
The multiple award-winning 2.5 TFSI produces 270 kW (367 hp) and 465 Nm (343.0 lb‑ft) of torque in the new RS 3 Sportback. The turbocharged engine accelerates the compact five‑door from 0 to 100 km/h in 4.3 seconds, and top speed can be increased to 280 km/h (174.0 mph) upon request. In the NEDC, it consumes just 8.1 liters of fuel per 100 kilometers (29.0 US mpg), with CO2 emissions of 189 grams per kilometer (304.2 g/mi).
A seven-speed S tronic, which shifts even faster than in the previous model, directs the power of the 2.5 TFSI to the quattro permanent all‑wheel drive system. The quattro system features torque vectoring based on intelligent software and is designed through‑and‑through for maximum driving enjoyment. The new Audi RS 3 Sportback steers directly into corners. On low-friction road surfaces, drivers can even perform controlled drifts, if desired.
The chassis of the five‑door model also sets standards. Compared with the Audi A3 Sportback, the body is 25 millimeters (1.0 in) lower. The pivot bearings of the front axle, the progressive steering, the RS‑specific sport suspension and optional Audi magnetic ride adaptive damper control are designed specifically for the RS. Audi mounts carbon fiber-ceramic brake discs behind the 19‑inch wheels on the front axle upon request – a first in the premium compact segment.
The Audi RS 3 Sportback complete package is rounded out with sharp interior and exterior details and a generous list of equipment. The new top model of the A3 family is rolling into dealerships in summer 2015.
Power in compact form – the new Audi RS 3 Sportback.
Audi presents the most powerful car in the premium compact segment: The new RS 3 Sportback produces 270 kW (367 hp) and delivers 465 Nm (343.0 lb-ft) of torque to the crankshaft. The 2.5 TFSI accelerates the five‑door model from 0 to 100 km/h (62.1 mph) in 4.3 seconds and goes on to reach an optional top speed of 280 km/h (174.0 mph).
The 2.5 TFSI in the new Audi RS 3 Sportback guarantees to thrill with immense pulling power, eager revving and its own unique acoustic experience. The throaty roar and snarl backed by the rhythm of the 1 - 2 - 4 - 5 - 3 five-cylinder ignition sequence is the classic Audi soundtrack. Two flaps in the exhaust pipes downstream of the muffler control the exhaust flow to provide for an even more intensive sound experience that varies with engine load and speed. The driver can control these flaps via the Audi drive select system. The RS exhaust system is designed for high flow. For the first time in this segment, Audi offers a sport exhaust system as an option.
Powerful five-cylinder engines have a long tradition at Audi. During the 1980s, they powered the Audi rally cars, touring cars and production models to the front of the pack. The first RS model, the RS 2 from 1994, also had such an engine. The five‑cylinder made its comeback in 2009 in the Audi TT RS; it made its way into the RS 3 Sportback in 2011 and two years later into the RS Q3. The 2.5 liter engine has been voted “International Engine of the Year” in its class five years in a row since 2010.
The five-cylinder unit produces 270 kW (367 hp) from a displacement of 2,480 cc: a remarkable specific output of 108.9 kW (148.0 hp) per liter. Driveability is impressive. The peak torque of 465 Nm (343.0 lb-ft) is already available at 1,625 rpm and remains constant through 5,550 rpm. The sprint from 60 to 100 km/h (37.3 to 62.1 mph) in fourth gear takes just 4.1 seconds; it takes just 5.8 seconds to go from 80 to 120 km/h (49.7 to 74.6 mph) in fifth gear.
The 2.5 TFSI catapults the new Audi RS 3 Sportback to 100 km/h (62.1 mph) from a standing start in 4.3 seconds – the best in its class. Acceleration is electronically capped at 250 km/h (155.3 mph). Top speed can be optionally raised to 280 km/h (174.0 mph), which is also unique in the compact sports car segment. In the NEDC, the entry-level RS model consumes just 8.1 liters of fuel per 100 kilometers (29.0 mph), ten percent less than its predecessor. This corresponds to 189 grams CO2 per kilometer (304.2 g/mi). A recuperation system, a demand-controlled oil pump and a newly developed start-stop system that turns off the engine shortly before the car comes to a stop contribute to this. The emissions rating is Euro 6.
Just 49 centimeters (19.3 in) long, the five-cylinder is very short. It weighs approximately 180 kilograms (396.8 lb). Its crankcase is made of vermicular graphite cast iron, an extremely strong, yet lightweight material. Perfectly placed reinforcements enhance the block’s loadability. A small team of specially trained experts build the 2.5 TFSI by hand at the Audi engine plant in Győr, Hungary.
The turbocharger, which develops up to 1.3 bar of charge pressure, has a theoretical throughput of 1,100 kilograms (2,425.1 lb) of air per hour. The intercooler lowers the temperature of the compressed air. The interplay of turbocharging and direct injection enables a high 10.0:1 compression ratio and correspondingly good efficiency. Flaps in the intake manifold cause the inflowing air to rotate. The camshafts, each of which can be adjusted through 42 degrees of camshaft angle, further optimize the mixture.
Seven-speed S tronic.
The standard seven-speed S tronic transfers the power of the 2.5 TFSI via three shafts – one drive shaft and two output shafts. Like all dual-clutch transmissions, it comprises two partial gearboxes. The direct shifting process takes place lightning-fast and with no perceptible interruption of power by simultaneously opening and closing both clutches. New detailed solutions for filling the clutches with oil and the interplay with the engine make gear changes faster than ever. With the Audi drive select system in dynamic mode, each shift is accompanied by double-clutching.
The driver of the new Audi RS 3 Sportback can choose between two automatic modes for the seven-speed S tronic or shift manually using the shift paddles on the steering wheel or the selector lever. The launch control system provides for optimal traction and minimal tire slip when sprinting from a standing start. The lower gears are sportily short; seventh gear is tall to reduce fuel consumption. A plug-connected angle drive connects the ultra-compact gearbox with the prop shaft – a design that displays intelligent lightweight construction down to the last detail.
quattro permanent all-wheel drive.
The quattro permanent all-wheel drive system transfers the power of the 2.5 TFSI to the road with supreme ease. Its central component is the electronically controlled, hydraulically activated multi-plate clutch. The newly developed part is mounted at the rear axle for reasons of axle load distribution. The multi-plate clutch uses software custom tailored for the Audi RS 3 Sportback. It distributes the available torque as needed to the front and rear axles in the blink of an eye. Depending on the driving style and coefficient of friction, between 50 and 100 percent of the available torque can be sent to the rear axle.
The electric pump, which develops the necessary oil pressure of max. 38 bar, is highly efficient. It is activated immediately the instant road grip drops or the driver adopts a sportier style. The weight of the clutch was reduced by 1.4 kilograms (3.1 lb) versus the previous version by eliminating the pressure accumulator. Another example of targeted lightweight construction.
Control of the multi-plate clutch is integrated into the Audi drive select system. With its very sport configuration, it uses all handling-relevant information, such as the steering angle. In dynamic mode and when the ESC Electronic Stabilization Control system is set to sport mode, power is transferred sooner and in greater amounts to the rear axle for even better handling, giving the new Audi RS 3 Sportback very agile and direct turn-in. This enables the driver to even perform controlled drifts on low-friction road surfaces. The front axle pulls the car back onto a straight line when exiting a bend.
Torque vectoring makes the handling of the Audi RS 3 Sportback even more perfect. During fast cornering, it slightly brakes the interior wheels, which are under a reduced load. This enables both wheels on the axle to transfer more power to the road. Thanks to the difference in propulsive forces, the car turns slightly into the corner and supports the driver’s sporty driving style.
The chassis complements the dynamics of the drivetrain perfectly. Precisely guided by its sensitive steering, the new Audi RS 3 Sportback takes all types of corners quickly and stably. Its handling limits are very high and effortlessly manageable.
The McPherson front suspension has been widened to a track of 1,559 millimeters (5.1 ft) and includes specially developed, high-strength aluminum pivot bearings. The standard progressive steering varies its ratio between 15.3:1 and 10.9:1 as a function of steering input. Its efficient, electromechanical servo boost works with an RS-typical characteristic.
The rear axle, which as a track width of 1,514 millimeters (5.0 ft), is a four-link construction with rods of high-strength steel that handle the longitudinal and lateral forces separately. As with the front axle, these forces are directed to a subframe. The taut RS sport suspension lowers the body by 25 millimeters (1.0 in) compared with the A3 Sportback. The Audi magnetic ride adaptive damper system is available as an option. Its management is integrated into the standard Audi drive select dynamic handling system, which includes the modes comfort, auto, dynamic and individual.
The dynamic, new top model of the A3 series rolls on 19-inch, cast aluminum wheels in five-arm rotor design with size 235/35 tires. Audi offers machine-polished 19-inch wheels in matt titanium look or high-gloss anthracite black. The top tire option includes size 255/30 tires up front and 235/35 at the rear.
The internally ventilated brake discs measure 370 millimeters (14.6 in) in diameter at the front and 310 millimeters (12.2 in) at the rear. The front friction rings feature a weight-saving wave design and are perforated for maximum heat dissipation. Pins connect them to aluminum brake caps, and they are gripped by eight-piston fixed calipers painted black (red optional) with RS logos.
One of the technologies that differentiate the new Audi RS 3 Sportback from its competitors are the optional carbon fiber-ceramic brake discs on the front axle. They also measure 370 millimeters (14.6 in) and are gripped by anthracite gray calipers. The Electronic Stabilization Control (ESC) offers a sport mode and can also be entirely deactivated with an extended push of a button.
Body and exterior design.
The power-to-weight ratio plays a very key role in a sporty car. With the new Audi RS 3 Sportback, each hp has to move just 4.14 kilograms (9.1 lb). The practical five-door compact has a curb weight (without driver) of just 1,520 kilograms (3,351.0 lb), 55 kilograms (121.3 lb) less than its predecessor.
The basis for this top value is the Volkswagen Group’s modular transverse matrix (MQB) with its strict lightweight construction concept. The occupant cell contains many components of ultra-high-strength, hot-shaped steel, and the engine hood is made of aluminum. The orientation of the engine in combination with the multi-plate clutch and the battery, which are located in front of and behind the rear axle, respectively, contributes to a favorable axle load distribution.
The new top model in the A3 series reveals its potential at first glance. The Singleframe grille features a high-gloss black, honeycomb-look grille and a frame in matt aluminum look. The charge air flows in through the air inlet below the license plate frame. The large air inlets framed by bold contours provide air to the engine’s supplemental radiator and the transmission oil cooler. The blade integrated into the front apron extends upward into the air inlets to form a vertical dividing bar.
Viewed in profile, the widened front fenders, chiseled side sills, matt aluminum-look mirror housings and the large roof spoiler of the Audi RS 3 Sportback immediately catch the eye. A pronounced bumper, high-gloss black diffuser insert with honeycomb grille and four bars plus two large, oval tailpipes make for a bold rear. RS 3 badges adorn the Singleframe grille and the rear hatch.
Dedicated individualists can order additional features, including a carbon engine cover. The matt aluminum and gloss black styling packages are also particularly attractive. Besides exterior details with distinctive surface, they also include a quattro logo in titanium gray in the air inlet. The eight paint finishes include two new shades: Nardo gray and Catalunya red, metallic. The latter color is exclusive to the Audi RS 3 Sportback.
Interior and Equipment.
The interior of the new Audi RS 3 Sportback is in sporty black and accentuated with RS badges. The sport seats are covered in Fine Nappa leather with contrasting stitching in rock gray. Wrapped in leather and Alcantara, the RS multifunction sport steering wheel is flattened at the bottom, and the selector lever also features a particularly sporty design. The driver information system includes a boost pressure indicator, an oil temperature gauge and a lap timer.
Fine details round out the atmosphere of dynamics and extraordinary craftsmanship. The pedals and footrest are made of stainless steel; the door trim inserts are Alcantara. As is typical for RS models, the door openers are slender double bars and the inlays are in 3D-design “Black” (optionally available in Aluminum Race or carbon). The dials in the RS instrument cluster are black, the needles red and the scales white. High-quality applications in gloss anthracite black frame the instruments.
Standard equipment in the new Audi RS 3 Sportback also includes the parking system plus and the MMI radio. Options include S sport seats with diamond pattern, embossed logos and optional light-colored upholstery, and for the first time in the compact segment the newly developed RS bucket seats with integrated side airbags and a carbon seat shell, which are seven kilograms (15.4 lb) lighter than the basic sport seat. Another attractive option is the RS 3 interior design package with red accents on the knee pad, the air vents, the floor mats and the seat belts. This color also shimmers through the perforations of the S sport seats.
The infotainment and driver assistance systems from the A3 series, including MMI navigation plus with MMI touch, are available without restriction in the new top model. The comfort and convenience package includes features such as power-adjustable and heated front seats, four-way lumbar supports, automatically dimming exterior mirrors and a light and rain sensor.
Deliveries of the powerful five-door model are scheduled to begin in summer 2015.
