TT-RS

The Audi TT RS: A Pure Driving Machine Developing 340 bhp
Source: Audi AG

The Audi TT RS: A Pure Driving Machine developing 340 bhp Audi is once again producing a five-cylinder engine – and a very special one at that. Arriving at dealerships this summer (Germany), the TT RS has a turbocharged 2.5-liter engine with direct gasoline injection; it produces 250 kW (340 bhp) and 450 Nm (331.90 lb.-ft.) of torque. The blazing five-cylinder engine enables the TT RS to perform extraordinary feats. In conjunction with quattro permanent all-wheel drive and a high-performance chassis, the engine makes the compact Audi TT RS a top-notch sports car – available as a coupé or roadster.

Sporty five-cylinder gasoline engines have a long legacy at Audi. The most famous is arguably the turbocharged 2.1-liter engine in the Audi quattro. The first version, which was launched in 1980, offered an impressive 147 kW (200 bhp). And the Sport quattro from 1984, directly inspired by motorsport, delivered a whopping 225 kW (306 bhp). For 25 years, turbochargers and quattro have been a dynamic formula for success.

Audi has resumed using this recipe. Designed from scratch, the five-cylinder engine combines a turbocharger with FSI direct gasoline injection to elevate the TT RS to a high-performance sports car. The TFSI delivers 250 kW (340 bhp) from a displacement of 2,480 cc (151.34 cu in): a specific output of 100.8 kW (137.1 bhp) per liter.

The power-to-weight ratio is also outstanding. In the case of the Coupé, which weighs in at a mere 1,450 kilograms (3,196.70 pounds), the power-to-weight ratio is just 4.3 kilograms per bhp. The Roadster has a weight of 1,510 kilograms (3,328.98 pounds) and a power-to-weight ratio of 4.4 kilograms per bhp – thanks to its extremely lightweight and largely aluminum body constructed as per the Audi Space Frame principle.

The TT RS Coupé rockets from 0 to 100 km/h (0 to 62.14 mph) in 4.6 seconds; the Roadster needs just a tenth of a second longer. The limited top speed of 250 km/h (155.34 mph) is merely the official figure for both versions; as an option, Audi can increase it to 280 km/h (173.98 mph).

Almost even more impressive is the aggressive pulling power. The maximum torque of 450 Nm (331.90 lb.-ft.) is always available between 1,600 and 5,300 rpm. In addition, the TT RS overtakes without the slightest effort. Last but not least, its engine makes passengers’ skin tingle time and again thanks to its speedy and powerful response, its inspiring free-revving character, and its unmistakably guttural tailpipes: five-cylinder classical music by Audi!

Compact and Lightweight: The Five-cylinder TFSI

As an uncompromising sports-car engine, the 2.5-liter TFSI is ultra-compact. Just 49 centimeters (19.29 inches) in length, it is ideally suited for transverse installation in the TT RS. And its weight of just 183 kilograms (403.45 pounds) also sets a record. The crankcase is made of vermicular-graphite cast iron. This high-tech material unites the utmost in strength with low weight; it has otherwise only been used for the large TDI engines from Audi. Perfectly placed reinforcements enhance the block’s loadability. The lightweight cylinder head, the pistons, and the connecting rod are lightweight as well as high-strength.

The ultra-powerful five-cylinder engine is extremely fuel-efficient, requiring an average of just 9.2 liters/100 km [25.57 mpg] as regards the Coupé (Roadster: 9.5 l/100 km [24.76 mpg]). Switchable flaps in the intake manifold mix the incoming air in a calculated configuration. Injected at a pressure as high as 120 bar by the common-rail system, the gasoline swirls intensely in the combustion chamber – which in turn cools the walls. This subsequently facilitates a compression ratio of 10.0:1, which is very high for a turbocharged engine. Both of the adjustable camshafts, controlled via chains, also enhance charging efficiency with respect to the air-fuel mixture.

The large turbocharger generates up to 1.2 bar of boost pressure. The intercooler, fed air ideally by the lower segment of the single frame radiator grille, reduces the temperature of compressed air by over 80 percent at full load.

When an Audi TT RS driver pushes the standard Sport button on the center tunnel, a flap installed in the left exhaust tailpipe renders the exhaust noise even more robust and intense while boosting engine responsiveness. An optional Sport exhaust system is available with matt black tailpipe trims and sound flap.

For Purists: The Driveline

The Audi TT RS is the first classic sports car in the Audi RS family. Like the RS 4 and the RS 6, the Audi TT RS was developed by quattro GmbH as a pure, no-holds-barred driving machine. A new six-speed manual transmission conveys the engine’s tremendous power, and permits easy and precise operation thanks to a specially designed shift lever boasting particularly short shift travel. The transmission’s defining characteristics are a high efficiency ratio and a sportily narrow spread of the gear ratios.

The Audi TT RS features quattro permanent all-wheel drive as standard equipment. Its heart lies at the rear axle: an electronically controlled, hydraulic multi-plate clutch. If a situation calls for it, the clutch redirects a majority of the torque input from the front wheels to the rear wheels.

Within milliseconds, a powerful electrical pump in conjunction with an accumulator presses together the clutch’s plates via hydraulic pressure. Additions to the quattro powertrain include a constant velocity joint before the propeller shaft and a compact rear-axle differential – both are heavy-duty components.

The quattro drivetrain grants the Audi TT RS outstanding traction, fascinating dynamics, and superb stability. Winding rural routes or some laps around a racetrack allow the superior handling to shine. The precise and responsive steering, the instantaneous reactions of the chassis, the neutrality at the cornering limit, the grip while exiting a curve, and – time and again – the engine’s thrilling power: every mile in an Audi TT RS exudes the distilled essence of sportiness.

High-tech Excellence from Audi: Chassis and Body

The chassis of the Audi TT RS builds on the cutting-edge foundation of the base TT design. The four-link rear suspension, which handles longitudinal and lateral forces separately, plays a crucial role. The electromechanical steering is highly efficient and the power steering adjusts to the vehicle’s speed. With aluminum in the front and sheet steel in the back, the body’s innovative mixture of materials results in a well-balanced axle-load distribution, excellent crash safety, and the outstanding rigidity which lays the cornerstone for the car’s precise handling.

The standard sports chassis, which lowers the body by 10 millimeters (0.39 inches), features tightly tuned springs and shock absorbers. The optional Audi magnetic ride adaptive damping system allows the driver to select one of two modes for the shock absorbers by simply pushing the Sport button. Dynamic mode enables the TT RS to hug the road; Comfort mode provides a pleasantly balanced ride perfect for long journeys.

The sportiest version in the TT model line boasts 18-inch wheels fitted with 245/45 tires. They are complemented by mighty ventilated disc brakes, which measure 370 millimeters (14.57 inches) in diameter at the front and 310 millimeters (12.20 inches) at the rear. So that heat dissipates quickly, the front friction rings are perforated. They, in turn, are connected by hollow pins to the aluminum brake discs, which are encircled by black four-piston brake calipers made of aluminum and bearing RS logos.

The Electronic Stabilization Program (ESP) can be switched off partially or entirely. In Sport mode, the engine does not intervene to monitor traction and, correspondingly, the brakes engage later than otherwise. In the second mode, the ESP is fully deactivated.

The Face of Power: The Exterior

At just 4.20 meters (13.78 feet) in length, the vigorously compact Audi TT RS hints at its explosive potential from the very first glimpse. The front spoiler tapers downward into a splitter, reminiscent of a racing car. The large and squared air inlets have diamond-shaped inserts. And the high-gloss black single frame grille with a frame in matt aluminum look and the TT RS badge bear the same styling. The xenon plus headlights with LED daytime running lights notify faraway drivers that an Audi TT RS is approaching.

The sides of the vehicle are accentuated by large wheels in 5 twin-spoke design, vigorous side sills, and exterior-mirror casings in matt aluminum look. At the tail end, the two large oval exhaust tailpipes – spaced apart – are encircled by a diffuser insert. Here, too, is a TT RS badge. A stationary rear spoiler is standard, though customers can opt for one which automatically extends and retracts.

Thanks to a drag coefficient of just 0.3, the 2+2-seat coupé and the two-seat roadster glide effortlessly through the wind. Audi offers the TT RS in eight colors. Among them are four exclusive options: Daytona Gray, pearl effect; Mugello Blue, pearl effect; Sepang Blue, pearl effect; and Suzuka Gray, metallic. The Roadster’s soft top comes in black or dark gray.

    The Audi R8 5.2 FSI quattro: Breathtaking Performance
    Source: Audi AG

     

  • The new 5.2-liter, ten-cylinder engine puts out 525 hp
  • Sprint to 100 km/h in 3.9 seconds, top speed 316 km/h
  • High-performance sports car with striking designAudi is launching the next variant of its top-of-the-line model. With the R8, the brand has established itself at the forefront of high-end sports cars from the very start – and now comes the R8 V10. Its 5.2-liter, ten-cylinder engine churns out 525 hp and 391 lb-ft of torque, which makes for breathtaking performance. With superior Audi technologies such as quattro all-wheel drive, the lightweight aluminum body, the innovative all-LED headlights, and its striking design, the R8 V10 takes pole position against the competition.

    The R8 V10 is the result of cumulative know-how from Audi’s string of Le Mans victories. Its naturally aspirated engine combines racing technology such as dry sump lubrication with FSI gasoline direct injection. The ten-cylinder design is the perfect synthesis for impressive top performance, mighty pulling power, and low weight. Starting in 2009, this engine will also prove its potential on the world’s racetracks – in the new R8 racing car Audi is developing for customer teams in conformance with the GT3 rules.

    The V10 engine in the production sports car will be almost identical in construction to the one in the racing version. Its displacement is 5,204 cc, at 6,500 rpm it delivers 391 lb-ft of torque, at 8,000 rpm its power tops out at 525 hp.

    The specific power output is 100.9 hp per liter of displacement – and each hp has to propel only 3.09 kilograms (6.91 lb) of weight, because the Audi R8 V10 in the version with the six-speed manual gearshift weighs only 1,620 kilograms (3571 lb). The engine accounts for 258 of these kilograms (569 lb) – that’s only 31 kilos (68 lb) more than the V8.

    The Audi R8 5.2 FSI quattro rockets from zero to 100 km/h (62.14 mph) in 3.9 seconds. In the version with the sequentially shifting R tronic it reaches 200 km/h (124.27 mph) in another 8.1 seconds. Even then its propulsive power hardly lessens: it’s sufficient to reach a top speed of 316 km/h (196.35 mph). The immense force, the spontaneity and the thrust of the acceleration, plus the sound of the engine – all these impressions coalesce into a breathtaking sports car experience. The V10 plays a concert with growling bass tones and powerful high notes, which grows into a grandiose fortissimo as the engine revs up. This sonorous acceleration doesn’t reach its limit until 8,700 rpm.

    The 5.2-liter powerplant uses direct injection according to the FSI principle developed by Audi. A common rail system injects the fuel into the combustion chambers with up to 120 bar of pressure. Direct injection reduces the susceptibility to knocking and provides a certain amount of cooling through the evaporation of the fuel, which in turn supports a high compression ratio of 12.5:1. This in turn contributes to superior performance and improves fuel economy. The R8 V10 with R tronic gets by on an average of 17.17 US mpg.

  • For maximum dynamics: low center of gravity engine

    The technical refinements of the long-stroke ten-cylinder engine include dry sump lubrication, which allows the engine to be mounted low within the chassis. The wide cylinder angle of 90 degrees also makes for a low center of gravity. The crankcase is a high-strength aluminum-alloy casting produced in a complex process. The connecting rods are made of forged steel, the pistons of aluminum. The four camshafts are chain-driven and each is adjustable through 42 degrees. This provides great latitude in controlling the valve timing. In combination with the straight, flow-optimized ducts of the intake manifold, this improves the charge throughout the entire speed range.

    The R8 5.2 FSI quattro has a six-speed transmission. A precise and smooth-shifting manual transmission comes as standard equipment. The sequential R tronic is available as an option. The high-tech gearshift conveys an authentic racing feel – with the rocker switches at the steering wheel and the short shifting times of usually less than one-tenth of a second. When the driver actuates the Launch Control program by pressing a button, the R8 V10 takes off in a vehement quick-start with electronically controlled tire slip – both with the R tronic and with the manual transmission.

    A contributing factor to the wide lead in traction and driving safety of the Audi R8 V10 over the competition is quattro all-wheel drive – it’s the superior technology especially for a high-performance sports car. Four powered wheels get more grip than two. They enable the driver to step on the gas sooner when coming out of a curve. It’s not only the traction that benefits, but also the transverse dynamics and the stability.

    44 to 56 percent – the ideal axle load distribution

    The Audi R8 chassis offers both dynamic performance and astonishing levels of comfort on long distances. This high-performance sports car from Audi eagerly responds to any steering action with instant ease, achieves lateral acceleration of up to 1.2 g, and handles any situation with superb driving safety. Its mid-engine design provides an ideal axle load distribution of 44 to 56 percent.

    The wheel suspensions on dual aluminum wishbones front and rear – a classic racing technology – are optimized for neutral self-steering characteristics. Even more than in the eight-cylinder R8, this setup is designed for maximum performance. 19-inch wheels equipped with tire pressure monitoring display are standard equipment. Their 10-spoke Y design is exclusive to the R8 V10. Tire sizes are 235/35 front and 295/30 rear.

    The car features a high-end damper technology as standard: Audi magnetic ride adapts the characteristics of the suspension in milliseconds to the nature of the road surface and to the driving style. Suspended in the oil of the shock absorbers are tiny magnetic particles which, when a voltage is applied, rearrange themselves so as to slow down the flow of oil through the valves.

    In the R8 V10, deceleration is provided by an extremely muscular braking system – eight brake pistons at the front and four at the rear grasp the brake disks, which are ventilated and perforated to ensure unimpeded heat transfer. The brake disks on the front axle have a diameter of 380 millimeters (15 in); the rear discs span 356 millimeters (14 in).

    The R8 5.2 FSI quattro is optionally available with a ceramic brake system whose disks are made of a composite material containing high-strength carbon fibers and abrasion-resistant silicon carbide. These are especially light: their combined weight is nine kilograms (19.84 lb) less than the weight of equivalent steel disks. The ceramic brakes can easily cope with the harsher requirements of racing, won’t corrode, and have a typical service life of 300,000 kilometers (186,400 miles). Their calipers are painted charcoal gray and emblazoned with the inscription “Audi ceramic”.

    Typically Audi: Sharp lines and an elegantly curved roof

    The wide, full shape of the R8 5.2 FSI quattro seems to hug the road. The brawny proportions and prominent wheel wells underscore its potential. The high-precision styling of the lines and the elegant curve of the roof are typical Audi features. A continuous contour optically connects the front, the wheel wells, the sides and the rear. Located well forward, the cab visually expresses the mid-engine design. The vertical air scoops (sideblades) on the sides are also indicative of the engine location. The massive aluminum gas cap is mounted flush within the right sideblade.

    The design of the Audi R8 has already impressed experts, as evidenced by the double victory in the “World Car of the Year Awards 2008”. In the ten-cylinder model, the styling has been sharpened up even more.

    The front air inlets, which feed air to the coolers, and the lip of the front apron are painted in high-gloss black. The number of cross-braces has been reduced from four to two. The vanes of the single-frame grille have a striking chrome finish.

    A very distinctive highlight of the R8 V10 are the all-LED headlights as standard equipment. Audi is the world’s first automaker to use LEDs for the high beam, low beam, daytime running lights, and turn signals. Each headlight integrates 54 of these high-tech light sources. With a color temperature of 6,000 Kelvin the LED light closely resembles daylight, which is less tiring to the eyes in night driving. Further advantages of the LEDs include brilliant illumination, low energy consumption, and a virtually unlimited service life.

    Special details also distinguish the body of the R8 V10. Its sideblades are more accentuated than in the eight-cylinder version. The side sills are more striking and wider; the exhaust grilles at the rear windows have a matt aluminum look. Through the large rear window, the ten-cylinder engine is clearly visible in its consummate technical beauty.

    When in motion, this Audi high-performance sports car creates a downforce that keeps it in firm contact with the road – thanks to a rear spoiler which deploys automatically at 100 km/h and the fully enclosed underbody, which terminates in a sharply upward-curved diffuser. The dominant color at the rear end is high-gloss black, including the settings of the LED tail lights. The air outlets at the rear end also have only two cross-braces, and the exhaust system terminates in two large oval tailpipes.

    Audi sets the example – in body weight and rigidity

    The body of a sports car must be especially lightweight and rigid. Audi meets these requirements with the technology of the Audi Space Frame (ASF) and its high-tech aluminum construction. The body-in-white of the R8 V10, which includes an engine frame made of ultra-light magnesium, weighs only 210 kilograms (463 lb), and the quality of its lightweight design – the relation of weight to torsional rigidity – is the best in the sports car segment. The body is composed of profile extrusions, sheet aluminum and very complex gusset castings, all held together by 99 meters (325 ft) of welding seams, 782 rivets, and 308 special screws.

    The interior of the R8 V10 provides a unique racing ambience at the luxury level. Its dominant element is the so-called monoposto – a wide arc that contains the steering wheel and the cockpit. As always in an Audi, the workmanship is of the highest quality. The surfaces of the dashboard and doors are lined with fine materials and adorned with precisely stitched decorative seams. Many customizing solutions are available: Audi supplies leather in a wide range of colors, packages with a carbon and piano-lacquer finish, or a made-to-measure luggage set. quattro GmbH, which has developed and is producing the R8 V10, also provides solutions for unconventional requirements.

    The great everyday utility of the Audi R8 V10 is based in part on its spacious interior made possible by the long wheelbase of 2.65 meters (8.69 ft). Drivers and passengers of any size will always find a perfect sitting position. Visibility too is surprisingly good. Slender hinge pillars optimize the obliquely forward field of view. Another advantage for convenient everyday use is the luggage space: 100 liters (3.53 cu ft) fit under the front hood, another 90 liters (3.18 cu ft) can be stowed behind the seats. There is also room for two golf bags.

    The Audi R8 5.2 FSI quattro combines its colossal performance with a generous complement of standard equipment. Highlights include heatable seat covers made of Fine Nappa leather, a driver information system, the navigation system plus and the Bang & Olufsen sound system along with deluxe automatic air conditioning and an alarm system. The instruments and the gearshift knob are decorated with red rings; the footrests and the rocker switches of the R tronic have an aluminum finish.

    The list of options includes other highly attractive features – such as the Audi parking system advanced with its integrated rearview camera or numerous Audi exclusive customization options. Various leather packages provide a luxurious touch, while the bucket seats from the Audi exclusive program bring a highly concentrated racing atmosphere into the R8 V10.

    The Audi R8 5.2 FSI quattro will be rolled out in Germany in the second quarter of 2009 at a basic price of EUR 142,400.
