Audi TT

Styling of the Audi TT began in the spring of 1994 at the Volkswagen Group Design Center in California. The TT was first shown as a concept car at the 1995 Frankfurt Motor Show. The design is credited to J Mays and Freeman Thomas, Martin Smith and Romulus Rost contributing to the interior design. A laser beam welding technique, which enabled seamless design features on the first-generation TT, delayed its introduction. Audi did not offer an automatic transmission option for the TT until 2003, when it offered a dual clutch six-speed Direct-Shift Gearbox (DSG), with the United Kingdom TT variants becoming the world's first market for a dual clutch transmission configured for a right-hand drive vehicle, although the outright 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. ==Name==

The Audi TT takes its name from the Isle of Man TT (Tourist Trophy) motorcycle race — where NSU, Audi's predecessor, had enjoyed considerable motor racing success. NSU marque began competing at the Isle of Man TT in 1907 with the UK manager Martin Geiger finishing in fifth position in the single-cylinder race. The 1938 Isle of Man Lightweight TT race was won by Ewald Kluge with a 250 cc supercharged DKW motor-cycle and the DKW and NSU companies later merged into the company now known as Audi. The Audi TT also follows the NSU 1000TT, 1200TT and TTS cars of the 1960s in taking their names from the race. The TT nameplate has also been attributed to the phrase "Technology & Tradition". ==TT Mk1 (Type 8N, 1998–2006)==

}} }} }} The production model (internal designation '''Type 8N''') was launched as a coupé in September 1998, followed by a roadster in August 1999. It is based on the Volkswagen Group A4 (PQ34) platform as used for the Volkswagen Golf Mk4, the original Audi A3, the Škoda Octavia, and others. The styling differed little from the concept, except for slightly reprofiled bumpers, and the addition of rear quarterlight windows behind the doors. Factory production commenced in October 1998. Early TTs were cited in a series of fatalities from accidents involving speeds over , abrupt lane changes or sharp turns. Both the coupé and roadster variants were recalled in late 1999/early 2000, to improve the car's handling predictability at very high speeds. Audi's Electronic Stability Programme (ESP) or Anti Slip Regulation (ASR) were added, as well as a rear spoiler, along with modifications to the suspension system. All changes were incorporated into subsequent production. The Audi TT was nominated for the North American Car of the Year award for 2000 and made Car and Driver magazine's Ten Best list for 2000 and 2001. By 2003, Audi revised the TT, with a number of small styling and practicality improvements. Production of the first generation (Type 8N) ended in June 2006. Powertrain Mechanically, the TT shared an identical powertrain layout with other Volkswagen Group cars. The TT uses a transversely mounted internal combustion engine, with either front-wheel drive or 'quattro four-wheel drive' available as an option. It was first available with a 1.8-litre inline four-cylinder 20-valve turbocharged engine in two states of DIN-rated power outputs; and . The engines share the same fundamental design, but the 225 PS version features a larger K04 turbocharger (180 PS version came with a smaller K03), an additional intercooler on the left side (complementing the existing right-side intercooler), larger 20mm wrist-pins, a dual tailpipe exhaust, intake manifold with inlet on driver's side, and a few other internals – designed to accommodate the increase in turbo boost, from roughly peak, to . Haldex Traction enabled four-wheel drive, branded "Quattro", was optional on the 180 engine and standard on the more powerful 225 version. The original four-cylinder engine range was complemented with a VR6 engine rated at and of torque in early 2003, which came as standard with the quattro four-wheel-drive system. In July 2003, a new six-speed dual clutch transmission – dubbed the Direct-Shift Gearbox (DSG), which improves acceleration through much-reduced shift times, was offered, along with a stiffer suspension. Aerodynamics According to Audi Head of Design Marc Lichte, the curved outline and rounded bodywork of the Mk1 TT's design was inspired by Bauhaus. This simplified curved shape was unusual at the time. The drag coefficient of the original TT is 0.35, which is similar to its competitors such as the BMW Z4 and the Mazda MX-5. However, the TT was involved in a number of high-speed accidents which were attributed to aerodynamic instability at high speeds. To solve these issues, Audi added modified control arms and firmer shock absorbers on both the front and rear suspension as well as a rear spoiler. (known as the in Europe) or TT QS. Built by AUDI AG's high-performance specialist subsidiary quattro GmbH, it had increased power from its 1.8-litre turbocharged engine – rising to and of torque – and a reduction in weight of to , The complaint alleged that the timing belts failed prior to the owner's manual's service interval. The parties reached a class-wide settlement, with preliminary approval of the settlement granted in May 2008. In May 2008, a class action suit reached a nationwide settlement regarding allegedly defective instrument clusters on 2000–2004, and 2005 model year Audi TTs. Owners were entitled to submit claims for repairs, replacement and/or cash reimbursement for out-of-pocket expenses and received a two-year instrument cluster warranty extension. Safety 2.7T Quattro gmbH Concept For the 30th anniversary Quattro gmbH unveiled an Imola Yellow TT that sported a 2.7 L Bi-Turbo V6 engine from a B5 Audi RS4 that produced and at 2,500 rpm which was manufactured in 2001. This was accomplished by using a B5 RS4 donor car, which included engine, transmission, rear differential, axles, brakes, and wheels from a B5 Avant. Using the RS4 drivetrain, Audi had the ability to utilize a Torsen based 6-speed Quattro manual transmission in a car that is normally using a transverse engine layout and Haldex based all wheel drive system. ==TT Mk2 (Type 8J, 2006–2014)==

A preview of the second-generation TT was provided in the form of the Audi Shooting Brake concept car, shown at the Tokyo Motor Show in 2005. This concept was an insight into the new TT, but featured angular styling, and a "shooting-brake" two-door hatchback body style. Audi debuted the second-generation TT, internal designation '''Type 8J''', on 6 April 2006, using the Volkswagen Group A5 (PQ35) platform with aluminium front bodypanels, and steel in the rear, to enhance its near-neutral front-to-rear weight distribution. Available in front-wheel drive or "quattro" four-wheel drive layout, the TT was again offered as a 2+2 Coupé, and as a two-seater Roadster. The second generation was five inches longer and three inches wider than its predecessor. Factory production commenced during August 2006. 8J powertrain The powertrain options initially only included petrol engines, which consist of either one of two inline four-cylinder engines – the new 1.8-litre EA888 Turbocharged Fuel Stratified Injection (TFSI) (available initially only in Germany, later elsewhere from mid 2009), or the more common and established EA113-variant 2.0-litre TFSI. The Fuel Stratified Injection (FSI) technology was derived from the Audi Le Mans endurance race cars, and offers improved fuel efficiency as well as an increased power output and cleaner emissions. The 3.2-litre 'V6' badged VR6 engine was carried over from the previous generation. 2.0 TFSI quattro models, with the latest EA888 engine, became available in 2009 model year. A six-speed manual transmission is standard, with the six-speed Direct-Shift Gearbox (now called "S-TRONIC" on all Audi models) as an option for all engines. Quattro on-demand four-wheel drive, again using the Haldex Traction clutch is available – standard on V6 models, but not available on the 1.8 TFSI. 8J suspension and other features Like all its PQ35 platform-mates, the 8J TT has a multi-link fully independent rear suspension to complement the front independent suspension. The entire suspension system can be enhanced with Audi's new active suspension, "Audi Magnetic Ride", available as an option. This is based on BWI Group's MagneRide, which uses magneto rheological dampers (this means that an electronic control unit for the suspension will automatically adjust its damping properties depending on the current road conditions and driving manner). The new TT also features a revised rear spoiler which preserves the clean aesthetics of the TT when not raised. The spoiler automatically deploys at 125 km/h (78 mph) to increase down-force, and retracts again below 80 km/h (50 mph). The spoiler can be manually controlled via a switch on the lower centre console. Manual operation by the switch reverts to automatic operation (i.e.: manual mode is cancelled) if the vehicle speed rises above the stated limit. Audi offered the first diesel engined version of the Audi TT in the European market, the . As its name indicates, it is only available with four-wheel-drive, and is also available in Coupé and Roadster versions. with a heavily revised 2.0 TFSI engine. It was available with a choice of either a six-speed close-ratio manual transmission, and a new two-stage sports-biased Electronic Stability Programme (ESP). Radially ventilated front disc brakes are clamped by a single-piston gloss black caliper emblazoned with a bold TTS logo, and a lap timer is prominent in the centre of the instrument cluster. 9Jx18" '5-parallel-spoke' design alloy wheels are standard, The exterior has some changes over the standard model – with a TTS body styling: with redesigned front, with larger air intakes, redesigned rear bumper, side sill extensions, and four exhaust tailpipes. The car went on sale in the US at November 2008. In 2014, at the International Motor Show in Geneva, Audi unveiled the new TTS model for the 2016 model year, alongside the standard 2016 Audi TT model. Both models were planned to go on sale in the beginning of 2015. TT Clubsport quattro concept Audi displayed a new show car variant of the second generation Audi TT – the Audi TT Clubsport quattro, at the 2008 Wörthersee Tour at Pörtschach am Wörthersee in Austria. Shown only in an open-topped "speedster" variant, its 2.0 TFSI engine has been tuned to give . and developed by Audi's high-performance subsidiary quattro GmbH at Neckarsulm, Germany, Audi released the first compact sports car Audi "RS" variant – the '''''', which was available from 2009 in Coupé and Roadster variants. The TT RS featured a new 2.5-litre Inline-5 turbocharged petrol engine. Ever since the original Audi "RS" model – the Audi RS2 Avant – all Audi "RS" models were assembled at the quattro GmbH factory in Neckarsulm. The TT RS is the first Audi RS vehicle that didn't have any of its assembly performed in Neckarsulm but was completely assembled in the Audi factory in Győr, Hungary, Additions to the quattro system include a constant velocity joint before the cardan propeller shaft, and a compact rear-axle differential – upgraded to cope with the increased torque from the five-cylinder turbo engine. Like the TTS, the TT RS has a lower ride height, In 2010, the TT-RS was confirmed for the US market. The decision was influenced by an internet petition to bring the TT-RS stateside, which succeeded with over 11,000 signatures. The TT-RS arrived in Q3 2011 as a 2012 model. In 2012, the TT RS plus was launched. It featured the uprated version of the TT RS' engine that had originally been developed for the RS Q3 concept car; this version of the engine produces at 5500 rpm, and of torque at 1650 rpm. As a result of this power increase, Audi claimed that the 0- time had decreased to 4.3 seconds for the manual version, and 4.1 seconds for the S-tronic version. Audi was reported to stop offering 3.2-litre V6 (VR6) models in North America from 2010 model year. 8J awards The second generation TT has been honoured with many awards, including the inaugural Drive Car of the Year, Top Gear Coupé of the Year 2006, Fifth Gear Car of the Year 2006, Autobild Most Beautiful Car, and World Design Car of the Year 2007, as well as being a finalist for World Car of the Year. In addition, an HPA-prepared version of the car was the winner of the SEMA Gran Turismo Award in 2007. The Audi TT has been the What Car? "best Coupe of the Year" for six consecutive years since 2007. A 2019 iSeeCars study named the TT as the longest-lasting sports car most likely to exceed 150,000 miles.

The Audi TT Offroad Concept was unveiled as an SUV concept version of the Audi TT at the 2014 Auto China. The SUV utilized a hybrid system coupled with the 2.0-litre TFSI Inline-4 engine producing a total of and of torque. The SUV utilises a 6-speed dual clutch automatic transmission. The hybrid system consists of a electric motor on the front axle and an electric motor on the rear axle. In full EV mode, the vehicle uses the rear motor only; Hybrid and Sport modes utilise all three power sources, and all-wheel-drive traction is applied as needed. Performance figures include a acceleration time of 5.2 seconds and an electronically limited top speed of . The distinguishing features of the concept include matrix LED headlights and two new assistance systems: One that scans intersections for potentially dangerous situations, and a second that connects to a municipality's traffic-light system in order to recommend a perfect speed to reach the next light when it is green. The interior is relatively close to the TT's with leather upholstery from Italian fashion brand Poltrona Frau and features a high-tech TFT display in front of the driver populated with the information that would normally be projected onto a central, dash-mounted screen—i.e. navigation, entertainment. The trunk of the vehicle contains a 1:8 scale RC car as a souvenir. File:Audi TT Offroad Concept (22).JPG|Audi TT Off-Road Concept ==Marketing==
