# Audi TT

The Audi TT is a production front-engine, 2-door, 2+2 sports coupé and roadster, manufactured and marketed by Audi from 1998 to 2023 across three generations.
For each of its three generations, the TT has been based on consecutive generations of Volkswagen's "Group A" platforms, starting with its "PQ34" fourth generation. The TT shares powertrain and suspension layouts with its platform mates, including the Audi A3, like a transversely mounted front-engine, powering front-wheel drive or four-wheel drive, and fully independent suspension using MacPherson struts in front.
The TT's first two generations were assembled by Audi's Hungarian subsidiary, one of the world's largest engine manufacturing plants, using bodyshells manufactured and painted at Audi's Ingolstadt plant and parts made entirely by the Hungarian factory for the third generation.
The last of the 662,762 Audi TTs was manufactured in November 2023.

## Design

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, with Hartmut Warkuss, Peter Schreyer, 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 112 mph (180 km/h), 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 shares an identical powertrain layout with its related Volkswagen Group-mates. 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; 180 PS (132 kW; 178 hp) and 225 PS (165 kW; 222 hp). 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 10 pounds per square inch (0.7 bar) peak, to 15 pounds per square inch (1.0 bar). 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 3,189 cc (3.2 L; 194.6 cu in) VR6 engine rated at 250 PS (247 bhp; 184 kW) and 320 N⋅m (236 lb⋅ft) 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.

### TT quattro Sport

In 2005, Audi released the Coupé-only limited edition. Just 1,165 were produced. 800 with steering wheel on the right side, 365 with steering wheel on the left side. (900 sold in the UK, not the 1,000 originally planned) Audi TT quattro Sport (known as the Audi TT Club Sport 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 240 PS (177 kW; 237 hp) and 320 N⋅m (236 lbf⋅ft) of torque – and a reduction in weight of 75 kg (165 lb) to 1,390 kg (3,064 lb), which allowed for a 0–62 mph (0–100 km/h) time of 5.9 seconds, and an electronically limited top speed of 155 mph (249 km/h).
This weight reduction was achieved by removing the spare wheel, rear harmonic damper, rear parcel shelf and rear seats, and the standard fitment air conditioning. The main battery was also relocated to the rear of the vehicle in order to maintain weight distribution as much as possible. Lightweight fixed-back Recaro bucket seats graced the interior. Distinguishable from other TT Coupés by its two-tone paint scheme (Phantom Black pearl painted roof, pillars and mirror housings, in combination with either Avus Silver, Phantom Black, Mauritius Blue or Misano Red body colour) and unique 18" 15-spoke cast aluminium alloy wheels, plus the same body kit as fitted to the TT 3.2 V6, the TT quattro Sport also featured black exhaust tailpipes and uprated suspension settings and new wheels, 1⁄2 in (13 mm) wider at the rear for improved handling. The brochure stated V6-spec brakes were to be fitted, however models delivered in the UK came with the standard 225 spec brake callipers which were red-painted.

### Lawsuits

In June 2007, a class action lawsuit was filed against Volkswagen Group of America, alleging the timing belts for model year 1999–2003 Audi and Volkswagen vehicles equipped with a 1.8-litre turbocharged engine failed prematurely. 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.

### 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 280 kW (381 PS; 375 hp) and 440 N⋅m (325 lb⋅ft) 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)

In August 2004, Audi announced that the next generation TT would be manufactured using aluminium, and would go into production in 2007. 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.

### 2.0 TDI quattro

Launched at the 2008 Geneva Motor Show, Audi offered the first diesel engined version of the Audi TT in the European market, the Audi TT 2.0 TDI quattro. As its name indicates, it is only available with four-wheel-drive, and is also available in Coupé and Roadster versions. Power comes from the new 2.0-litre Turbocharged Direct Injection (TDI) engine, now with 16 valves, double overhead camshaft (DOHC), 1.8-bar (30 psi) common rail fuel delivery and eight-hole piezo fuel injectors, which produces a DIN-rated output of 125 kW (170 PS; 168 bhp) at 4,200 rpm and torque of 350 N⋅m (258 lbf⋅ft) at 1,750 to 2,500 rpm. It includes a six-speed manual transmission.
Acceleration from standstill to 100 km/h (62.1 mph) on the Coupé is achieved in 7.5 seconds, and it will go on to reach a top speed of 226 km/h (140.4 mph). The slightly less aerodynamically efficient Roadster reaches 100 km/h (62 mph) in 7.7 seconds, with a top speed of 223 km/h (138.6 mph).
Audi claims average fuel consumption for the Coupé variant with this 2.0 TDI engine is 5.3 litres per 100 kilometres (53.3 mpg$_{‑imp}$; 44.4 mpg$_{‑US}$), which achieves a CO$_2$ emissions rating of 139 gram/km. The Roadster TDI achieves an average 5.5 litres per 100 kilometres (51.4 mpg$_{‑imp}$; 42.8 mpg$_{‑US}$) and CO$_2$ of 144 gram/km.

### TT S-Line

As an additional package a standard Audi TT can be bought from factory with a special body kit upgrade to make it look like the Audi TT-RS version. The upgrade includes a fixed rear spoiler, and Alcantara/leather sports seats (Silk Nappa, Fine Nappa leather optional).

### TTS

At the 2008 North American International Auto Show (NAIAS) in Detroit, Audi released the first Audi "S" model of the TT range – the Audi TTS quattro, with a heavily revised 2.0 TFSI engine. The cylinder block, cylinder head and the fuel injectors have all been modified from the base 2.0 TFSI engine (ID: CDL). Together with other modifications, this engine produces a DIN-rated power output of 200 kW (272 PS; 268 hp), and generates a torque of 350 N⋅m (258 lbf⋅ft) from 2,500 to 5,000 rpm.
It was available with a choice of either a six-speed close-ratio manual transmission, or a six-speed 'S tronic' transmission. In the United States, the S tronic gearbox was the only available transmission. Like all Audi "S" models, it was only available with four-wheel drive as standard.
The suspension was lowered by 10 millimetres (0.4 in) over the standard models, and includes "Audi Magnetic Ride" as standard 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, with 245/40 ZR18 high-performance tyres. 19" '5-spoke star' wheels and tyres are optional. 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.
Official performance figures include a 0-100 km/h (0–62 mph) acceleration time of 5.2 seconds, with the Roadster four-tenths slower at 5.6 seconds.[31] Top speed is electronically limited to 250 km/h (155 mph).
Audi UK offered eight TTS cars for official use by the race organisers at the 2008 Isle of Man TT motorcycle races.
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 221 kW (300 PS; 296 bhp). The soft-top on the standard TT Roadster has been deleted, and replaced with two "humps", along with two substantial roll bars. LED daytime running lamps, an aggressive body kit with large frontal air intakes, black-painted "single frame grille" and a lower spoiler lip complete the new look from the front. The axle track has been widened by 66 millimetres (2.6 in), with bolder and wider wheel arch extensions, polished 19-inch alloys, wider side sills and 255-section tyres are the highlight of the side profile. At the rear, twin polished stainless steel oval tail pipes exit aside a new rear diffuser.
Racing bucket seats, along with lightweight aluminium detail complete the interior look, and a six-speed S tronic dual-clutch transmission with quattro four-wheel drive and TTS spec brakes (340 mm (13.4 in) up front, and 310 mm (12.2 in) at the rear) complete the mechanicals.
Whilst the TT Clubsport quattro is primarily a "show car", Audi has not ruled out the possibility of small-scale production.

### TT RS

With its world debut at the 2009 Geneva Auto Show, and developed by Audi's high-performance subsidiary quattro GmbH at Neckarsulm, Germany, Audi released the first compact sports car Audi "RS" variant – the Audi TT RS, which was available from 2009 in Coupé and Roadster variants. The TT RS featured a new 2.5-litre Inline-5 turbocharged petrol engine. This 183 kg (403 lb) engine produces a DIN-rated power output of 250 kW (340 PS; 335 bhp) from 5,400 to 6,700 rpm, and torque of 450 N⋅m (332 lbf⋅ft) at 1,600–5,300 rpm.
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, alongside the base Audi TT.
The TT RS has a new short-shift close-ratio six-speed manual transmission, and like all "RS" models, is only available with four-wheel-drive, with the TT RS using a specially adapted version of the latest generation multi-plate clutch from Haldex Traction. 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 10 millimetres (0.4 in) lower ride height, optional "Audi Magnetic Ride", and rides on standard 18-inch wheels with 245/45 ZR18 tyres (optional 19" or 20" wheels are also available). The brakes are upgraded to include two-piece cross-drilled and radially vented front discs, sized at 370 mm (14.6 in) in diameter. The front discs are clamped by gloss black painted four-piston calipers, adorned with the RS logo. Rear ventilated discs are sized at 310 mm (12.2 in) in diameter.
It includes a fixed rear spoiler (retractable optional), and has black interior with heated Alcantara/leather sports seats (Silk Nappa, Fine Nappa leather optional). The Recaro "RS bucket" seats, first seen in the Audi B7 RS4 are also available as an option. Also carried over from the B7 RS4 is the "Sport" button, which sharpens the throttle response and deepens the exhaust note, and a three-stage user-selectable Electronic Stability Programme (ESP).
Official performance figures indicate the TT RS Coupé will accelerate from a standstill to 100 km/h (62.1 mph) in 4.5 seconds (4.7 seconds for the Roadster), with an electronically limited top speed of 250 km/h (155 mph). There is a factory option to de-restrict the top speed to 280 km/h (174.0 mph). The Coupé has a kerb weight of 1,450 kg (3,197 lb), and the Roadster weighs in at 1,510 kg (3,329 lb).
As of 2010, the TT-RS is available with the 7-speed DSG automatic transmission capable of handling the torque delivered by the engine. The 6-speed gearbox used in the TT-S cannot cope with 450 N⋅m (332 lb⋅ft) of torque, which is why the TT-RS initially was offered only with a manual transmission.
The car went on sale in March 2009, with delivery beginning in summer.
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 355 hp (265 kW; 360 PS) at 5500 rpm, and 343 lb⋅ft (465 N⋅m) of torque at 1650 rpm. As a result of this power increase, Audi claimed that the 0-62 mph (100 km/h) time had decreased to 4.3 seconds for the manual version, and 4.1 seconds for the S-tronic version. In addition to this, Audi raised the top speed limiter, with the TT RS plus being restricted to 174 mph (280 km/h).

## TT Mk3 (Type FV/8S, 2014–2023)

Like its predecessor, the Audi TT FV/8S was previewed in the form of the Audi Allroad Shooting Brake concept car, shown at the Detroit Motor Show in 2014.
The third generation of the TT was unveiled at the 2014 Geneva Motor Show. The FV/8S generation utilises the Volkswagen Group MQB platform, and is available with a choice of TFSI and TDI engines. The 2.0 TFSI is available in two versions: a version producing 169 kW (230 PS; 227 hp) and 370 N⋅m (272.90 lb⋅ft) of torque in the TT and a version producing 228 kW (310 PS; 306 hp) and 380 N⋅m (280.27 lb⋅ft) of torque in the TTS. A 2.0 TDI Inline-four engine producing 135 kW (184 PS; 181 hp) and 380 N⋅m (280.27 lb⋅ft) of torque is also available as an option for the TT. The TFSI engines are available with all wheel drive. The TDI comes in front wheel drive configuration, but was then later released with the Audi's quattro all wheel drive.
In 2019, the models were updated with the following specifications:
* TT 40: with a 2.0L engine producing 145 kW (197 PS; 194 hp) and 320 N⋅m (236.02 lb⋅ft) of torque

* TTS (from 2021 until 2023): with a 2.0L engine producing 235 kW (320 PS; 315 hp) and 400 N⋅m (295.02 lb⋅ft) of torque

#### TT RS Iconic Edition

In October 2022, Audi launched the TT RS Coupé Iconic Edition, available only in Europe and produced 100 cars (of which only 11 are right-hand drive).

#### TT/TT S Final Edition

In 2023, Audi unveiled the Final Edition of the TT, coinciding with the discontinuation of the TT due to declining sales of the two-door coupé segment. The Final Edition TTs feature black exterior accents consisting of the tailpipes, badges and rings, door mirrors, and fixed spoiler. The roadster is equipped with black roll bars and a black wind diffuser, while the coupé receives privacy glass. The TT Final Edition receives 20-inch, Y-style five spoke matte grey finished wheels with red brake calipers, while the TT S Final Edition is fitted with seven spoke black alloy wheels of Audi Sport. Both body styles are available in either Chronos Grey Metallic, Glacier White, or Tango Red body colors.
On the interior, the Final Edition is equipped with the extended leather package, which adds the material to the center console trim, armrests, and door pull handles. A red stitched Alcantara steering wheel is fitted, with a 12 o'clock marker unique to the Final Edition. The air vents, armrests, and center console of the coupe are adorned with Tango Red accents. The Alcantara-trimmed seats feature red stitching, and the floor mats receive red piping as well. The Final Edition is exclusive to the United Kingdom, with Audi confirming that it will not be available in North America.

## Audi TT Offroad

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 304 kW (413 PS; 408 hp) and 649 N⋅m (479 lb⋅ft) of torque. The SUV utilises a 6-speed dual clutch automatic transmission. The hybrid system consists of a 40 kW (54 PS; 54 hp) electric motor on the front axle and an 85 kW (116 PS; 114 hp) 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 0–62 mph (0–100 km/h) acceleration time of 5.2 seconds and an electronically limited top speed of 155 mph (249 km/h). 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.
