2001 Audi TT Couple

2001 Audi TT

The production model was launched as a coupé in September 1998, followed by a roadster in August 1999, based on the Volkswagen A platform used for the Volkswagen Golf, Skoda Octavia and others. The TT uses a transversely mounted engine with front or quattro all wheel drive. It was first available with a 1.8 L turbocharged inline four cylinder 20-valve engine. For the first two years of production, both front wheel drive and quattro models featured a 180 PS (132 kW) version of this engine.

In 2001, a more powerful Quattro model was released which was equipped with a 225 PS (165 kW) engine which shares the same basic design but features a larger turbocharger, an additional intercooler on the driver's side, forged connecting rods, a dual exhaust, and a few other internals designed to accommodate the increase in turbo boost from roughly 10 psi peak to 15.All TT models were recalled in late 1999/early 2000 following concerns over the car's handling which was considered unstable under high-speed cornering as the result of throttle lift-off oversteer - a number of modifications were made, which were subsequently incorporated into all future examples: rear-wing spoilers were fitted (to reduce lift) and suspension settings were altered (to increase understeer).

The original four cylinder engine range was complemented with a 250 PS (184 kW) 3.2 L VR6 in early 2003, which comes with the quattro all-wheel drive system. In October 2004 a new DSG (dual-clutch) gearbox, which improves acceleration through drastically reduced shift time, was offered along with a stiffer suspension.Audi has developed the TT with some notable improvements, including a lightened and power-boosted "quattro Sport" model, and 240 PS (176 kW) and a top speed of 250 km/h (155 mph), however the handling and steering are considered by BBC's Top Gear presenter, Jeremy Clarkson, to be "boring". It compares with the Nissan 350Z which has more grip. It should be noted, however, that the TT's handling character is deliberate, as Audi vehicles are generally designed to exhibit understeer (a characteristic determined by suspension design, the effect of the quattro all-wheel drive system, and other factors).

Understeer is inherently a safer handling characteristic, as it is easier for novice and casual drivers to predict and control the vehicle (and thus the car can appeal to a much broader market). Sports car purists and driving enthusiasts, however, generally favor oversteer (which the Nissan 350Z exhibits) to understeer, as the former makes for a more involving and spirited driving experience.The 2006 TT model was pulled from California and other states that had adopted California emission standards because the 2006 Audi TT did not meet with these states' emissions standards.

TT design

The TT's styling is regarded by many as a watershed moment in automobile design. From its introduction as a concept car in 1995, and as a production car in 1998, the design was regarded by many as bold, innovative, and evolutionary. While the car borrowed a few design elements from earlier vehicles, the overall design was considered by many to be truly unique. With its distinctive, rounded bodywork, bold use of bare aluminum (actually anodized aluminum), and a lack of defined bumpers, the TT represented a departure from much of the styling that dominated the car market at that time.

The success and popularity of the TT's iconic design gave many automotive designers (and manufacturers) greater latitude to experiment with bold, distinctive design. The TT's influence can be seen in the design elements of many vehicles released after the TT.The TT is often regarded as the vehicle that made people take a second look at Audi. No longer just a second-tier European maker, Audi emerged as a serious competitor for the likes of BMW and Mercedes-Benz. The then-new B5-platform A4 model was a substantial improvement on its Audi 80 predecessor; these two models firmly secured Audi's position as a prestige marque.

2001 Audi Avantissimo

The Audi Avantissimo is a concept car by the German automobile manufacturer Audi. The Audi Avantissimo debuted at the 2001 Frankfurt Motor Show in Germany. Audi planned the Avantissimo to be luxurious and distinguished, but very swift at the same time.The Audi Avantissimo had a 4.2 L V8 engine equipped with twin turbochargers. This engine developed about 430 hp and 600 ft·lbf of torque. The Avantissimo had a six-speed automatic transmission and also had all wheel drive.

2001 Audi A8 Quattro

The Audi A8 is a full-size luxury car built by the German automaker Audi to replace the V8 model as its flagship offering. Although the Volkswagen Phaeton, long wheelbase Jaguar XJ8 and Lexus LS 430 compete in the same size and price category as the A8, the Mercedes-Benz S-Class and BMW 7 Series are often thought to be its primary rivals. On the market since 1994, it has fully established itself as a popular alternative to these long-running competitors. Most versions feature Quattro all-wheel-drive as standard as well as a multitronic or tiptronic automatic transmission.

First generation (1994-2003)

The A8 debuted in Europe in 1994, although it wasn't until 1997 that it became available in North America. Unlike the V8 model, which was built on an existing steel platform, the A8 debuted on Audi's then-new D2 platform, an all aluminum space frame which helped to significantly reduce weight without being any less rigid.In addition to being the world's first car built on an entirely aluminum platform, updates to the car in 1997 included the addition of six interior airbags, making the A8 the first vehicle to be so equipped.

For 2001, Audi introduced their new W12 engine, a compact 6.0 L unit developed by mating two 3.0 L VR6 engines together at the crankshaft, similar to the 3.6 L engine from the V8 model which had been created by mating two inline-four cylinder engines at the crankshaft. The engine quickly became available in the A8, although only to European and Asian customers and only in long-wheelbase versions of the car. From its introduction through its discontinuation in 2003, only 750 of the W12 models were produced.

2001 Audi A6 Avant

2001 Audi A6 Avant

In 1997 the scene changed strikingly for the A6 avant. With the introduction of an ambitious new design (C5) and a new pack of engines, the A6 moved up a notch and was positioned alongside the hegemonious BMW 5-Series and the solid Mercedes E-class. The new A6 presented itself with a wide range of engines and configurations. The crisp 30-valve 2.4 and 2.8 V6 engines represented the bulk of the A6's development programme, but the resilient 2.5 V6 TDI and the powerful all-new Audi S6 were the flagships. As an alternative to the manual transmission, a 5-speed Tiptronic automatic transmission was also available.

The Avant body arrived in 1998.In 2000 the A6 received a facelift which saw little change in the design of the car but presented a few notable changes in terms of engines. The 1.8 L engine was removed and replaced by a 2.0 L powerplant with 130 PS (96 kW). The 1.9 L TDI was tweaked into producing a maximum of 130 PS (96 kW) and 310 Nm (228 ft.lbf), receiving a 6-speed gearbox in the process. The 2.4's power was slightly upgraded and the 2.8 V6 was replaced by a 3.0 L engine boosting 220 PS (162 kW). The turbocharged 2.7 L was given a tweak on the turbo resulting in 250 PS (184 kW) and 330 Nm (244 ft.lbf), controlled by standard quattro. The V6 Diesel was also slightly modified resulting in 163 PS (120 kW) (after the second modification) and 350 Nm (258 ft.lbf).

A new more powerful V6 diesel was also introduced presenting 180 bhp and 370 nm.Also new was the revolutionary Multitronic drive by wire continuously variable transmission, available in most front wheel drive models in the lineup. All models, except the 2.0 petrol and 1.9 TDI, were available with Audi's four wheel drive system, quattro. A four wheel drive version of the estate with raised ground clearance and slightly altered styling was sold as the Audi Allroad Quattro, Audi's first crossover SUV.In the late years of the A6 C5 design, a monstrous Audi RS6 model was presented.

Producing a staggering 450 PS (331 kW) and 560 Nm (413 ft.lbf), it propels the A6 from 0-100 km/h in 4.7 sec and on to 200 km/h in under 18 seconds. This model saw the end of the C5 design which was replaced in 2004 by a new model.

2001 Audi A4 Avant

An all-new A4 avant debuted in late 2000, now riding on the B6 platform. The 1.6 L base model remained unchanged, but most other gasoline engines received either displacement increases or power upgrades. The 1.8 20 valve Turbo was now available in two additional versions, with 150 or 180 PS (110 or 132 kW), this one with a standard six-speed gearbox, while the naturally aspirated 1.8 L straight-4 and 2.8 L V6 were replaced by 2.0 L and 3.0 L units, still with five valves per cylinder, the most powerful of which was capable of 220 PS (162 kW) and 300 Nm (221 ft.lbf) of torque.

The 1.9 TDI engine was upgraded to 130 PS and was now available with quattro, while the 2.5 V6 TDI high-end model was introduced with 180 PS (132 kW) and standard quattro. The Avant arrived in mid 2001.For 2002, Audi upgraded power in the 1.8 Turbo engines to 163 and 190 PS (120 and 140 kW respectively), and in the 2.5 TDI intermediate version to 163 PS. A year later, Audi reintroduced the S4, now powered by a 344 PS (253 kW) 4.2 L V8, as well as an A4 Cabrio convertible variant, finally replacing the 80-based Audi Cabriolet that had been discontinued in 1998.

Audi also introduced a continuously variable transmission developed by LuK, named Multitronic, which replaced the Tiptronic on front wheel drive models. The transmission won considerable praise from the automotive press and is generally regarded as being the best of its type in the world, due to its light weight and promptness in response, but its use was limited to models with a maximum of 310 Nm (229 ft.lbf).

Borrowing from the Audi A6, the boot was redesigned to remove the extension of the top edge with a smoother fold line, and the taillight assembly now forms part of the top line.A new cabriolet version of the A4 was introduced in 2002 to replace the ageing Audi 80-based model. It incorporated some minor styling changes which eventually found their way to the sedan version (such as body-colored lower bumper and sill panels).
