A two-door compact sports car, the Audi TT was manufactured by Audi Hungaria Motor Kft. in Gyor, Hungary since 1998 for the German automaker and Volkswagen Group subsidiary AUDI A.G. Today the TT is now in its second generation, and both generations have been available in two car body styles; as a 2+2 Coupe or two-seater Roadster. Both versions have been built on consecutive generations of the Volkswagen Group A platform beginning with the A4. Due to the platform-sharing, the TT has identical powertrain and suspension layouts as its related platform-mates; which includes a front-mounted transversely orientated engine, front-wheel drive or Haldex Traction-based Quattro on-demand four-wheel drive system, and fully independent front suspension using MacPherson struts.
In the spring of 1994 at the Volkswagen Group Design Center in California the styling of the Audi TT began. The TT was originally unveiled as a concept car at the 1995 Frankfurt Motor Show. J Mays and Freeman Thomas were credited for the design, along with Martin Smith and Romulus Rost who contributed to the award-winning interior design. The TT takes its name from the successful motor racing tradition of NSU in the British Isle of Man TT motorcycle race. In 1911 NSU began competing in the TT, and eventually merged into the company now known as Audi. The Audi TT follows the NUS 1000TT, 1200TT and TTS cars of the 1960s in taking their names from the race.
Enabling seamless design features on the first-generation TT was a previously unused laser beam welding adaptation, but which actually delayed its introduction. In the beginning Audi didn t offer any type of automatic transmission option for TT. From 2003 though a dual clutch six-speed Direct-Shift Gearbox became available, with the U.K. TT variants becoming the world s first user of a dual clutch transmission configured for a right-hand drive car. Though the major world first for a road car equipped with a dual clutch transmission was claimed earlier by a Volkswagen Group platform-mate; the left hand drive Volkswagen Golf Mk4 R32.
With an internal designation Typ 8N, the production model was introduced as a Coupe in September of 1998, followed closely by a roadster in August of 1999. The production model was based on the Volkswagen Group A4 platform as used for the Volkswagen Golf Mk4, the original Audi A3, the Skoda Octavia and others. Compared to the concept the production model was styled only a little different from the concept, except for the slightly re-profiled bumpers, and the addition of a rear quarterlight windows behind the doors. In October of 1998 the factory production commenced.
After a series of high-speed accidents in Europe, early TT models gained press coverage. During abrupt lane changes or sharp turns crashes were reported along with related fatalities that occurred at speeds in excess of 110 mph. Late in 1999 and early in 2000, both the coupe and roadster models were recalled to improve predictability of the car s handling at extreme high-speeds. Newly added were Audi s Electronic Stability Programme, and rear spoiler, along with suspension modifications. All of the changes and updates were subsequently incorporated into future series production version of the vehicle. In June of 2006 factory production of this generation ended.
Sharing an identical powertrain layout as its related Volkswagen Group platform-mates mechanically, the TT utilizes a transversely mounted internal combustion engine, with either front-wheel drive, or quattro on-demand four-wheel drive. Initially it was available with a 1.8 liter inline four-cylinder 20-valve turbocharged engine in two states of DIN-rated power outputs; 178 hp and 222 hp. All of these engine share the identical fundamental design, however the 166 kW version features a larger K04 turbocharger, an additional intercooler on the right side, forged connecting rods, a dual tailpipe exhaust and several other internals; which were designed to accommodate the increase in turbo boost; from around 10 lbs per square inch to 15 lbs per square inch. Branded as Quattro ; Haldex Traction enabled four wheel drive which was optional on the 180 engine, and was standard on the more powerful 225 version.
In early 2003 the original four cylinder engine range was integrated with a 184 kilowatts 3.2 liter VR6 engine, which came standard with the Quattro four-wheel drive system. The following July, a new six-speed dual clutch transmission called the Direct-Shift Gearbox which improved acceleration through much reduced shift times, was available, along with a stiffer suspension.
In 2005, Audi unveiled the Coupe-only limited edition Audi TT Quattro Sport. The Quattro sport was built by Audi A.G. high performance specialist subsidiary Quattro GmbH and it featured increased power from its 1.8 liter turbocharged engine rising to 27 hp and 236 lb ft of torque. It also was reduced in weight by 165 lbs which allowed it to reach 0 to 62.1 mph in just 5.9 seconds and it had a top speed of 155.3 mph. Audi achieved this weight lot by deleting the spare wheel, the removal of the rear parcel shelf and rear seats along with deleting the standard fitment air conditioning. On the inside, the Quattro sport featured lightweight fixed-back Recaro bucket seats. You could tell the Quattro Sport from the other TT Coupes by its two-tone paint scheme and the exclusive 18 15-spoe cast aluminum alloy wheels, plus the identical body kit fitted to the TT 3.2 V6, up-rated suspension settings, black exhaust tailpipes, V6-spec brakes with red-painted calipers up front and new wheels that were wider at the rear which greatly improved handling.
The first generation TT has undergone two U.S. class action lawsuits affective specific models. In 2007, Pearson, Soter, Simon, Warshaw and Penny at LLP and the Law Office of Robert L. Starr filed a class action lawsuit against Volkswagen Group of America claimed that the timing belts for model year 1999-2003 Audi and Volkswagen cars equipped with a 1.8 liter turbocharged engine fail prematurely. The vehicles included in the suit are the Audi TT, Audi A4 and the Volkswagen Passet. The plain claims that the timing belts fail prior to the service interval, as stated in the owner s manual. In May of 2008 the parties had reached a class-wide settlement and preliminary approval of the settlement was granted by the court. Another lawsuit entered May of 2008 alleged that the instrument clusters on 2000-2005 model year Audi TTs were defective.
For 2000, the original generation Audi TT was nominated for the North American Car of the Year award. For 2000 and 2001 it was also on Car and Driver magazine s Ten Best list.
In 2005, a sneak-peak of the second-generation TT was revealed in the form of the Audi Shooting Brake concept car at the Tokyo Motor Show in 2005. The concept featured angular styling, and a shooting brake two-door hatchback body style, and was an insight into the new TT design. On April 6, 2006 Audi unveiled the second-generation TT; internal designation Typ 8J. Constructed on the Volkswagen Group A5 platform, the 2nd generation TT utilized aluminum in the front body panels and steel in the rear which enhanced its near-neutral front-to-rear weight distribution. This vehicle was available in front-wheel drive or quattro four-wheel drive layout and it was available once again as a 2+2 Coupe and as a two-seater Roadster. In comparison to the previous generation, this newest generation is five inches longer and three inches wider. In August of 2006 factory production began.
In the beginning the powertrain options only included petrol engines, which consist of either one of two inline four cylinder engines; the all-new 1.8 liter EA888 Turbocharged Fuel Stratified Injection or the more common and established EA113-variant 2.0 liter TFSI. Derived from the Audi Le Mans endurance race cars, the Fuel Stratified Injection and offers advanced power output and cleaner emissions. Brought over from the previous year the 3.2 liter V6 badged VR6 engine was also available in the Canadian model. In the 2009 model year the 2.0 TSFI Quattro models with the latest EA888 engine.
Standard on this generation was a six-speed manual transmission with the six-speed Direct-Shift Gearbox as optional for all but 1.8 liter engine. Standard on V6 models was Quattro on-demand four-wheel drive, once again using the Haldex Traction clutch, but not available on 1.8 TFSI. The new 8J TT now featured a multi-link fully independent rear suspension which complimented the front independent suspension, much like all its PQ35 platform buddies. Audi Magnetic Ride was Audis new active suspension which enhanced the entire suspension system and was available as an option. This extra feature was based on Delphi s MagneRide, a suspension which utilized magneto rheological dampers. Also new on this TT was an updated rear spoiler that automatically extends at speeds greater than 75 mph and retracts again below 50 mph. This spoiler can be manually controlled by the driver through a switch on the dash.
Debuted at the 2008 Geneva Motor Show, the 2.0 TDI Quattro is the first diesel engined version of the Audi TT in the European market. As the name implies, it is only available with Quattro, and is available in Coupe and Roadster version. Power came from the new 2.0 liter Turbocharged Direct Injection engine, now with 16 valves, double overhead camshaft, 1,800-bar common rail fuel delivery and eight-hole piezo fuel injections that produces a DIN-rated output of 168 bhp at 4,200 revolutions per minute and torque of 258 lb/ft at 1,750 to 2,500 rpm. This model also includes a six-speed manual transmission.
Acceleration was rated from 0 to 62.1mph on the Coupe in just 7.5 seconds and could reach a top speed of 140.4 mph. The Roadster was slightly less aerodynamic and reached 0 to 62.1 mph in 7.7 seconds and had a top speed of 138 mph. Audi claims that the average fuel consumption for the Cope variant with the 2.0 TDI engine is 5.3 liters which achieves a CO2 emissions rating of 139 gram. The Roadster TDI achieves an average of 51.4 mph and CO2 of 144 gram.
Audi released the first Audi S model of the TT range at the 2008 North American International Auto Show in Detroit with a heavily revised 2.0 TFSI engine. The cylinder block, fuel injectors and cylinder head were all modified from the base 2.0 TFSI engine. Along with additional modifications, this engine produces a DIN-rated motive power output of 268 bhp and generates a torque turning force of 258 lb ft of torque from 2,500 to 5,000 rpm. The S was available with a choice of either a six-speed close-ratio manual transmission or a six-speed S tronic transmission. The S tronic gearbox was the only available transmission in the United States and it was only available with Quattro four-wheel drive as standard.
The suspension in the S was lowed by 0.4 inches in comparison to the standard models and included Audi Magnetic Ride as standard and a all-new two-stage sports-biased Electronic Stability Programme . Clamped by a single-piston gloss black caliper which was embellished with a bold TTS logo was the radially ventilated front disc brakes and a lap time that was prominently displayed in the center of the instrument cluster. Standard on the S were 9Jx18 5-parallel-spoke design alloy roadwheels with 245/40 ZR18 high performance tires. 19 5-spoke star wheels and tires were optional on this vehicle. Compared to the standard model the exterior featured some updates with a TTS body styling with a newly redesigned front, redesigned rear bumper, side sill extensions, four exhaust tailpipes and larger air intakes. The TTS s Coupe performance was recorded at 0-62.1mph in just 5.4 seconds, with the Roadster just two-tenths slower at 5.6 seconds. The top speed is electronically limited to 155mph.At the 2008 Isle of Man TT motorcycle races Audi offered 8 TTS cars for official use.
At the 2008 W rthersee Tour at P rtschach am W rthersee in Austria Audi debuted a new show car variant of the second generation Audi TT; the TT Clubsport Quattro. It was shown only in an open-topped speedster variant, and its 2.0 TFSI engine was tuned to give 296 bhp. The soft top from the standard TT Roadster disappeared and was replaced with two humps , along with two substantial roll bars. The Clubsport Quattro featured LED daytime running lamps, black-painted single frame grill , an aggressive body kit with large frontal air intakes and a lower spoiler lip. The axle trip was widened 2.6 inches with bolder and wider wheel arch extensions, wider side sills, polished 19-inch alloys and 255-section tires, and the rear were twin polished stainless steel oval tailpipes next to a new rear diffuser.
On the inside the Clubsport Quattro featured racing bucket seats, a six-speak S tronic dual-clutch transmission with Quattro four-wheel drive, TTS spec brakes and lightweight aluminum detail throughout the interior. Though Audi has not ruled out the possibility of a small scale production, it was primarily a show car .
Debuted at the 2009 Geneva Auto Show, Audi released the first ever compact sports car Audi RS model; the new Audi TT RS which was available from 2009 in Coupe and Roadster variants. Developed by Audi s high performance subsidiary Quattro GmbH at Neckarsulm, the new TT RS harks back to the sporting legacy of 1980s Audi Quattros with their high performance five-cylinder turbocharged engines. The TT RS included an all-new 2.5 liter inline five-cylinder Turbocharged Fuel Stratified Injection petrol engine which produced a DIN-rated motive power output of 335 bhp from 5,4000 to 6,700 rpm and a torque of 450 newton meters at 1,600-5,300 rpm.
The Audi RS2 Avant and all Audi RS models afterwards were assembled at the Quattro GmbH factory in Neckarsulm, Germany. The TT RS however will be the first Audi RS vehicle not assembled in Germany, instead it was completely assembled in the Audi factory in Gy r, Hungary alongside its lesser Audi TT mates.
Featuring a new short-shift close-ratio six-speed manual transmission the TT RS is only available with Audi s trademark Quattro four-wheel drive system, like all RS models. The TT RS utilized a specially adapted version of the latest generation multi-plate clutch from Haldex Traction. The Quattro system included addition like a constant velocity joint before the cardan propeller shaft and a compact rear-axle differential that was up-rated to cope with the increased torque from the five cylinder turbo engine. The TT RS featured a 0.4 inch lower ride height like the TTS and featured optional Audi Magnetic Ride and rides on a standard 18 inch road wheels with 245/45 ZR18 tires. The front discs on the TT RS are clamped by gloss black painted four-piston calipers which featured the RS logo and the braes were up-rated to include two-piece cross-drilled and radially vented front discs sized at 14.6 inches in diameter. The rear ventilated discs were 12.2 inches in diameter.
The Audi TT RS also featured a fixed rear spoiler with a retractable being an option. The interior was black with heated Alcantara/leathe sports seats with Silk Nappy and Fine Napppa leather as an option. Also available as an option were Recaro RS bucket seats that first appeared in the Audi B7 RS4. The Sport button which sharpened the throttle response and deepened the exhaust note was carried over from the B7 RS4 along with a three-stage user-selectable Electronic Stability Programme.
In March 2009 the TT RS went on sale and delivery began in the summer. The vehicle had a top speed of 155.3 mph and could achieve 0-62.1 mph in just 4.6 seconds, and 4.7 seconds for the roadster. A factory option de-restricted the top speed to 174.0 mph. The Coupe has a kerb weight of 3.197 lbs and the Roadster weighed 3,329 lbs.
The recipient of numerous awards, the second generation TT won the inaugural Drive Car of the Year, Top Gear Coupe of the Year in 2006, Fifth Gear Car of the Year in 2006, World Design Car of the Year 2007, Autobild Most Beautiful Car and being a finalist for World Car of the Year.By Jessica Donaldson
