The Audi TT is a two-door coupe marketed since 1998, also available in roadster . The TT name comes from the NSU model Prinz TT (The NSU brand was absorbed by Audi in 1977). The name of the TT is based on the NSU TT tradition which means Tourist Trophy of the Isle of Man.
The development of the Audi TT began in the spring of 1994 at the Volkswagen Group Design Center . The TT was first introduced as a concept car at the Frankfurt Motor Show in 1995
1 st generation – Audi TT (8N)
Based on the A platform of Volkswagen , the coupe , proposed in September 1998 , and the roadster , proposed in August 1999 are initially equipped with a four cylinder engine with five valves per cylinder, of 1.8 20 V turbo for 180 horses with a top speed of 238 km / h and acceleration from 0 to 100 km / h in 7.4 s . The upper one, which has four driving wheels (option on the model of 180 hp) delivers 225 hp with a maximum speed of 253 km / h and 0 to 100 km / hin 6.4 s . A six-cylinder 3.2 L in the low-pitched sound, a power of 250 hp at 6300 rev / min , a torque of 320 Nm at 2800 rev / min and 6.2 s to go from 0 to 100 km / h , complete range in early 2003 .
From an aesthetic point of view, a rear wing had to be installed and the suspension modified due to stability problems at high speed. Indeed, the rear lightened at high speed because of the shape of the car. The fin is used to add aerodynamic support .
In October 2004, a DSG dual-clutch sequential mechanical transmission is offered as an option. The speeds go in 200 milliseconds which ensures a linearity as well with the acceleration (identical to the turbo version) that by downshifting towards 3,250 rev / min with a small blow of automatic gas to facilitate the engagement of the report. This model is electronically limited to 250 km / h .
2 th generation – Audi TT (8J)
This restyled version of the Audi TT changes size but its sporty character remains present. Jorge Diez , a Catalan automotive designer , is at the origin of the style of the Audi TT and was careful not to radically change the forms that managed to the first version. These shapes remain curvaceous, without sharp edges but adopt new stylistic elements. This is the case of the Single Frame grille , now present on all Audi, almond fires stretched to the rear and more generous air intakes to better cool the engine. The taillights are the most original, new for the Audi style in 2007 and then taken on the Audi R8. These high-tech lights composed of opaque rectangles form luminous squares.
The ring mark replaces “its icon” with a more advanced aerodynamic model. The lengthening of the Audi TT benefits the Cx : it goes from 0.34 to 0.30. Thus, the new coupe is larger than the old, more profiled and has a retractable fin, which rises from 120 km / h to ensure better support to the road. It has a chassis developed specifically for this model made of 69% aluminum.
But the real novelty, and the bulk of sales, comes from the new block 4-cylinder turbo gasoline direct injection : the 2- liter TFSI 211 hp . The TT is now also available with a diesel engine, the 2.0 TDI 170 hp, and a new petrol engine, the 1.8- liter TFSI developing 160 hp. The Quattro transmission is standard on the 2.0 TDI but optional on the 2.0 TFSI.
The TT is also available in version 2.0l TFSi 200 hp until 2011, whose block allows acceleration from 0 to 100 in 6.6 seconds and 241 km / h in top speed. The sound of the 4 cylinders is raucous. The Audi TT also has a neat interior in the image of the brand: leather, aluminum and exemplary finish. The Audi TT is a competitor of the Mercedes-Benz SLK and the Peugeot RCZ .
