Audi launches RS3 Sportback

BY Joel Tam

Blazing performance, compact size. Audi has added a new model to its dynamic RS series: the Audi RS3 Sportback.

In the great tradition of the brand, its engine boasts five cylinders and turbocharging technology. From a displacement of 2.5 liters come 340 bhp of power and 450 Nm of torque, with an average fuel consumption of just 9.1 liters of fuel per 100 km.

Power is transmitted to the road via a seven-speed S tronic and quattro permanent all-wheel drive. 19-inch wheels and fenders made of carbon fiber reinforced plastic underscore the Audi RS3 Sportback's position of distinction.

The compact seven-speed S tronic transmits power from the five-cylinder engine via three shafts: one drive shaft and two output shafts. Like all dual-clutch transmissions, it comprises two transmission structures. The shifting process is extremely smooth, taking place in hundredths of a second as the clutches switch, with no perceptible interruption of pulling power. Seventh gear is very tall - a measure that reduces fuel consumption.

Each Audi RS model represents the pinnacle of its model line - the Audi RS3 Sportback, developed by quattro GmbH, now brings this dynamic philosophy to the compact category. It rockets from a dead stop to 100 km/h in 4.6 seconds. Top speed is electronically limited to 250 km/h. The guttural roaring and growling, backed by the signature rhythm of the five-cylinder firing order make up the classic Audi soundtrack. A sound flap in the exhaust branch intensifies the sound even further. The flap is controlled via the standard Sport button, which also varies the engine response.

Delivering power to the road with effortless ease, the quattro permanent all-wheel drive grants the Audi RS3 Sportback traction, dynamics, and stability. Its central component is an electronically controlled multi-plate clutch, mounted at the end of the propeller shaft to achieve a favorable axle load distribution. Located in its interior is a plate package bathed in oil.

Thanks to quattro, the propulsive power can be distributed to each axle as needed. Whenever slip occurs at one of the axles, an electric pump intervenes at lightning speed to increase the oil pressure. The pump presses the clutch plates together in a continuous fashion, thereby permitting the torque to be redirected accordingly. Thanks to a powerful accumulator, this process takes just a few milliseconds.

The driver can operate the seven-gear S tronic in two automatic modes and one manual mode. Gears are shifted using the paddles on the steering wheel or the selector lever. The launch control system manages the sprint from a dead stop, furnishing explosive turbo power with minimal tire slip.

The dynamic style is matched in the interior, entirely black and sporting a number of RS3 logos. The sports seats are upholstered in Fine Nappa leather with silver contrasting stitching; the inlays gleam in Piano finish black or the new Aluminum Race look; the leather multifunction sports steering wheel is flat-bottomed. The selector lever and instruments are specially designed. The driver information system can display the boost pressure and oil temperature as well as a lap timer.

The side view is dominated by the flared front fenders made of carbon fiber reinforced plastic (CFRP), prominent sill panels, exterior-mirror casings in matt aluminum look and a large roof spoiler. A high-gloss black diffusor insert and two elliptical exhaust tailpipes on the left accentuate the styling at the rear. RS3 badges adorn the single-frame grill and the rear hatch.

The stiff body lays the cornerstone for the Audi RS3 Sportback's precise handling; the chassis is what makes it happen. The four-link rear suspension - with a track measuring 1,528 mm - is anchored to a subframe and features high-strength-steel control arms that allow it to handle longitudinal and lateral forces separately. Widened to a 1,564-millimeter (61.57-inch) track, the front suspension is a McPherson strut construction, also with a separate subframe. The new range-topping model in the A3 series boasts 19-inch cast aluminum wheels fitted with 235/35 series tires at the front and 225/35 at the rear.

The internally ventilated disks measure 370 millimeters in diameter at the front and 310 millimeters at the rear. The front friction rings are perforated for maximum heat dissipation. They are connected by hollow pins to the aluminum brake disk covers, which are encircled by four-piston fixed calipers painted a high-gloss black and bearing RS logos. The electronic stabilization program (ESP) features a Sport mode and can be switched off entirely.

The Audi RS3 Sportback comes with an array of standard equipment including the Sport button, rear parking system, climate control, chorus radio system, and xenon plus headlights with LED daytime running lights. Audi offers customers a range of optional features: front bucket seats, roof rails in matt aluminum look, and styling packages in black or matt aluminum. Five exterior colors are available, plus an unlimited selection of custom paint finishes.
