TT Diesel

[Max]

Audi is once again setting standards, this time with the new Audi TT and its TDI engine—a model that combines pure sportiness and powerful performance with sensational efficiency. The Audi TT 2.0 TDI Coupe quattro and Audi TT Roadster 2.0 TDI quattro are the first series-production sports cars to feature diesel engines. It’s a compelling union: The two-liter engine generates dynamic propulsion with 125 kW (170 hp) and 350 Nm (258.15 lb-ft) of torque, yet the TT Coupe and TT Roadster consume an average of only 5.3 liters and 5.5 liters of fuel per 100 km (44.38 mpg and 42.77 mpg) respectively—unparalleled in the sports car segment.

 

Audi is setting the pace with this synthesis of excellent dynamism and low fuel consumption, as it has done for many years: Since debuting in 1989 the TDI engines from the brand with the four rings have been paving the way for the world’s most successful efficiency technology and acting as trendsetters for the entire automobile industry. Today, these powerful, refined and highly fuel-efficient engines represent a modern, smart take on sportiness. The run of victories achieved by the Audi R10 TDI diesel race car at the Le Mans 24 Hours and in the American Le Mans Series are impressive evidence of the tremendous potential of this technology.

 

The dynamic diesel engines from Audi exert an exciting impact not just in racing but also in series-production models—and now indeed in a sports car. The TT Coupe quattro with the 2.0 TDI sprints from zero to 100 km/h (62.14 mph) in 7.5 seconds and achieves a top speed of 226 km/h (140.43 mph). The Audi TT Roadster, likewise equipped with quattro permanent all-wheel drive, requires only an extra tenth of a second for the standard sprint, and continues up to a top speed of 223 km/h (138.57 mph). Both versions serve as outstanding examples of the success of the Audi efficiency strategy, thanks to their fuel efficiency ratings of 5.5 liters per 100 km (42.77 mpg), a figure that corresponds to CO2 emissions of only 145 grams/km.

 

Powerful, refined and efficient: The 2.0 TDI

The new four-cylinder TDI engine (engine displacement = 1,968 cc) represents a fresh take on the all-round compelling qualities of the TDI concept. Designers of the dual-camshaft, two-liter model looked to its predecessor—the most-produced diesel engine in the world—and expanded upon its major strengths: driving pleasure, efficiency and refinement.

 

The new common rail injection system is equipped with highly modern piezo injectors, whose eight-hole injection nozzles can perform up to five distinct injection sequences per cycle. This fine degree of modulation creates a modest pressure increase in the combustion chambers, resulting in a significantly reduced noise level. The system pressure of 1,800 bar allows fuel to form a fine dispersion, enabling precise, highly efficient combustion.

 

The turbocharger is also part of a new generation and operates with adjustable vanes that allow torque to build up rapidly. The positions of swirl flaps on the intake manifold are controlled by electric motors in order to adapt the flow of air to the current load and engine speed. The geometry of the engine’s pistons has been modified, and the acoustics of the camshaft drive belt have been overhauled. Just as they did in the preceding model, two balancing shafts reduce the vibrations arising in the crankshaft drive.

 

The cumulative result of this progress is a high maximum engine speed of 5,000 rpm and, most importantly, improved thermodynamics in the combustion chambers. What this means is that the engine can run on up to 60 percent recycled exhaust that has been thoroughly cooled by the radiator. This results in a drastic reduction in untreated NOx emissions, with the 2.0 TDI already meeting the threshold values of the upcoming Euro 5 standard.

 

Dynamic road performance

The 2.0 TDI in the Audi TT Coupe and the Audi TT Roadster delivers 125 kW (170 hp) at 4,200 rpm and sends a full 350 Nm (258.15 lb-ft) of torque to the crankshaft at engine speeds between 1,750 and 2,500 rpm. Operating quietly and generating little in the way of vibration, this model delivers a hefty amount of power at the lowest rpm levels and is highly responsive to input from the gas pedal. Its supreme power development lends this engine its own unique, fascinating character—that of a muscular, smart sports engine.

 

The Audi TT Coupe 2.0 TDI quattro easily leaves the gasoline-powered competition behind when accelerating from a standstill. It sprints from zero to 100 km/h (62.14 mph) in just 7.5 seconds and never looks back until it reaches 226 km/h (140.43 mph). The TT Roadster accelerates to 100 km/h (62.14 mph) in 7.7 seconds and keeps going up to 223 km/h (138.57 mph).

 

These models—the world’s first diesel sports cars—consume an average of only 5.3 liters and 5.5 liters of fuel per 100 km (44.38 mpg and 42.77 mpg) respectively, which corresponds to CO2 emissions of a mere 140 g/km and 145 g/km. In so doing, they are setting a benchmark that represents a veritable quantum leap in the sports car segment. With the TDI engine in the TT series, Audi once again establishes its leading role on the diesel market. The brand with the four rings is advancing progress and starting at the top.

 

In keeping with the theme of sporty performance, Audi has combined its two diesel-engine sports cars with highly effective manual six-speed transmissions whose short lever travel allows the driver to shift quickly, easily and precisely. The housings for these transmissions are made of lightweight, high-tech magnesium materials. Relatively long final transmission ratios have been employed to bring the drivetrain in line with the character of the TDI engine.

 

In light of their high torque values, Audi is equipping both of its new TT models with quattro permanent all-wheel drive. The heart of this system is an electronically controlled, hydraulically activated multi-plate clutch, which is located in the rear of the vehicle for improved weight distribution. This clutch generally distributes up to 85 percent of the engine power to the front axle and 15 percent to the rear axle; in extreme situations it can divert up to 100 percent of the power to either axle.

 

The overall concept: An exercise in uncompromised sportiness

Consistent efforts to reduce vehicle weight are also part of the efficiency strategy pursued by the brand with the four rings. Both sports cars are very lightweight: the 2 + 2-seater TT Coupe weighs only about 1,370 kilograms (3020.33 lbs) when empty, while the two-seater TT Roadster with soft top weighs roughly 1,415 kilograms (3119.54 lbs). Underlying these low weights is an innovative hybrid body construction developed by Audi. Front components are made of aluminum and utilize Space Frame technology; rear components are made of steel. This solution guarantees that the frame is as rigid as possible and optimizes load distribution between the axles.

 

The Audi TT Coupe and TT Roadster are dynamic, emotion-packed sports cars. As was the case with preceding models, these cars are impressive for their powerful design, whose dynamic flow continues on into the interior. The cockpit contains multiple nods to the circle motif, and the sports steering wheel with its flat-bottomed rim fits the driver’s hand like a glove. The sport seats are deep-set, providing a sporty seated position and firm lateral support. The backs of both rear seats fold down in the TT Coupe, making the trunk space grow from 290 to 700 cubic liters (10.24 – 24.72 cubic ft). The Roadster (250 liters, 8.83 cubic ft) comes with a practical load-through hatch upon request.

 

The sports suspension likewise offers extraordinarily dynamic features. The front suspension is pivoted on an aluminum subframe and has a wide track measuring 1,572 millimeters (61.89 inches).

 

A highly precise rack-and-pinion steering system with a direct steering ratio provides an intimate link between the driver and the road. Power steering with servo assist, which decreases as speed increases, is generated by an electromechanical drive that is even more efficient than a hydraulic pump.

 

The coil springs and shock absorbers in the four-link rear axle are situated in separate areas. The links are also finely differentiated: The layout of the trailing links, which absorb the propulsive and braking forces, is relatively soft to promote a comfortable ride. The connections to the three transverse links per wheel, on the other hand, are rigid in order to direct transverse forces into the body with precision.

 

The Audi TT Coupe 2.0 TDI quattro and Audi TT Roadster 2.0 TDI quattro roll on 16-inch, cast aluminum wheels fitted with 255/55 R16 tires. Behind the wheels are large disk brakes with pads that develop large coefficients of friction. The ESP stabilization program supports the neutral to slight understeering feel of the TT—the finishing touch on an overall portrait of exciting dynamics, exhilarating driving pleasure and stability you can count on.

 

Audi magnetic ride, a high-tech shock-absorber system available as an option, is an adaptive system that resolves the traditional conflict of interests between comfort and handling. A magneto-rheological fluid circulating in the shock absorbers changes the direction of the magnetic particles within milliseconds when electricity is applied; this alters the overall characteristics of the fluid and, in turn, modifies the damping characteristic. The driver can choose between “Normal” and “Sport” programs by flipping a switch.

 

Equipment makes a statement of refined style

Standard equipment for both of the new TT models reflects the sporty character and refined style of the series. Faux aluminum accents add a shine to gray inlays and various other components in the interior. The sports steering wheel comes with a Nappa leather cover. The climate control system (standard for the TT Coupe) regulates heating and ventilation in response to the level of sunlight. The driver information system and chorus audio system round out the standard equipment.

 

A wide array of high-tech equipment is available as options, including a highly modern generation of audio devices, electrically adjustable front seats, the adaptive light dynamic cornering light system and two navigation systems with a user interface based on the Audi MMI concept—a cut above the competition.

bonjour les tours !!!!!!!!! :(

 

++ :coucou:

[Max]

Maintenant il y en aura pour tous les gouts.

[AutoMat]

C'est vrai, le point positif c'est qu'il y en aura pour tous les gouts.

 

Le point negatif c'est que les TT essence vont devenir invendables .... :(

 

 

[fioung]

surtout qu'ils permettent le Quattro sur le TDI et pas sur le 2.0 TFSI...

à terme il restera le TDI et le TTS... :(

[Max]

Le TFSi aura droit à la boite S Tronic et le TDI au quattro.

[worky]

comme ca a été dit il y en aura pour tous les gouts :bigthumbup:

 

maintenant Audi doit avoir une demande et doit répondre à la concurrence.

 

personne n'est forcé de rouler en Tdi...

 

l'A4 se fait en Tdi et pourtant la RS4 est fantastique ;)

[fioung]

The Audi TT Coupe 2.0 TDI quattro and Audi TT Roadster 2.0 TDI quattro roll on 16-inch, cast aluminum wheels fitted with 255/55 R16 tires. fameux pneus :bigsmile: sûrement une erreur de frappe...

[seb77]

Vu le parc français 7 voitures sur 10 sont diesélisées, il y a une bonne parti des TT qui se vendront en TDi pour qui roule avec en premiere voiture, maintenant si on utilise le TT en seconde voiture, alors la version essence aura toujours sa cote, pour son moteur TFSI très réussi, sobre et performant.

[mini115]

donc le v6 :colere:

sa tombe bien je dois valider ma reservation.

je vais peut etre en reflechir cette nuit <_<

[patatus]

Apparamment c'est pour la semaine prochaine a Geneve:

ce sera sans moi...

[RIRI83]

ben moi je vais attendre le break TT2 TDI ....pour prendre une licence de taxi !!!!!!!!!!! :bigsmile: :bigsmile: :bigsmile:

moi, j'attends le TT-Camping car.. :bigthumbup:

[tony montana 180]

et moi tt pikup :bigthumbup: :eldiablo:

[F7R]

BEURK :bleble:

[tony montana 180]

comment ça beurk :degage2:

[F7R]

J'adore le new TT :malelovies:

 

mais pour moi c'est 3.2 only ou alors TT-S :hot: :eldiablo:

 

un mazout la dedans <_<

[fioung]

et le 2.0 TFSI ? <_<

 

[matiouse]

Le mythe TT Ne sera plus le même à présent... :furious: :furious:

[binome]

C'est clair !

j'ai rien contre le diesel, mais j'ai grandi avec l'image du

diesel = camions = fuel pour les chaudières = mazout pour les gros bateaux

Donc il fait avancer des voitures aussi, mais ce n'est pas un carburant "noble"...

On peut faire des voitures puissantes au diesel, de la même manière que les camions sont puissants.

Tout ça pour dire que TT diesel, pour moi y'a un problème d'image qui passe pas.

C'est surement une histoire de mentalité, mais je sais pas si je changerai.

Quant-aux futures générations, de toutes façons, elles se déplaceront en fusées avec des moteurs nucléaires

et elle mangeront des pilules nourrissantes à la place des repas (je m'emporte un peu, peut-être).

Enfin voilà quoi.

 

Bon et pourquoi pas un TT 4x4 alors ?

Ah, ça s'appelle quattro, ça existe déjà ?

[Lestatof91]

Bonjour :eldiablo:

 

Je reste légèrement dans le hors sujet : Le TT 4*4 effectivement... ça existe et le pick up aussi :rolleyes: bha oui souvenez vous de ce jolie TT utilitaire d'un pays nordique, je pense que nous nous souvenons tous des photos... non bon d'accord :

 

 

 

Sinon...oui la présentation du mazout, sans moi également....

 

[nicox93]

Ouai c'est limite si tu peux pas mettre un cercueil aussi tant qu'a faire ! :furious:

[mystique]

Il pourrait au moins mettre un filet histoire que tout s'envole pas avec la vitesse :eldiablo:

[fioung]

au moins il concilie son job et sa tuture :bigsmile:

[air jordan]

un TT2 avec un bonus ecotaxe c'est bien : on va l'avoir à moins de 32 000 euros neuf avec cette remise

 

ok je sors

 

[michaeldetoulon]

Moi j'ai toujours possédé des Diesel, j'apprécie ces moteurs très coupleux et bien entendu économique au vu de la consommation et du prix à la pompe.

 

Mais je deviens petit à petit antidiesel, et ça, depuis l'Eco-taxe, on va taxer du CO2 qui n'est absolument pas un polluant (seulement un gaz à effet de serre), mais aucune taxe contre les risques de cancer des poumons et des maladies respiratoires (asthme, bronchiolite, etc...) ?

 

Alors chouette un TT diesel, une R8 diesel, une RS4 diesel, etc... mais quel avenir pour notre santé ?. De toute façon, l'industrie produit toujours plus de CO2 chaque année et voila que bientôt non seulement 97% du parc va tourner au diesel en dégazant du CO2 (de toute manière) avec l'option cancer et maladies respiratoires ??? :closedeyes:

Les FAP n'arrangeant absolument pas ce problème, je dirais même qu'il l'aggrave en créant des micros-particules encore plus vicieux pour l'homme.

 

Aujourd'hui j'ai presque envie de dire que rouler à l'essence est un geste ÉCOLO ! :o

 

Alors, il y a encore 1 an ce TT j'en aurais rêvé, aujourd'hui il ne m'attire absolument plus !

 

 

[seb77]

Est ce que le moteur est toujours de type injecteurs pompe ou bien il passera par rampe commune, car en terme de sonorité ca n'a rien a voir, les IP sont bruyants et ca vibre de partout, les rampes communes de dernieres génération sont silencieuses. une idée ? avis aux spécialistes !

[Erty]

Rampe commune !

[worky]

faut peut etre remettre les choses à leurs places :

 

la pollution automobile représente + ou - 15 % de la pollution mondiale.

 

c'est pas un TT diesel qui va nous rendre encore plus malade...

 

quand on pense au nombre de vieux véhicules extremement polluants qui circulent

 

ca me fait un peu plus peur que les dernières motorisations diesels.

 

après je respecte completement ceux qui n'aiment pas ce type de motorisation :jap:

 

conduire une essence qui possède un fabuleux moteur et rentrer dans les tours est un grand moment :eldiablo:

 

et si on est vraiment écolo on roule avec un petit 3 cylindres essence ou une hybride non? ;)

 

 

[silversurfer]

biofuel ou ... le retour des moteurs essence !!

Modifié 1 mars 2008 par silversurfer

[jarod1601]

J'adore trop cette voiture.Maleuresement faisant beaucoup trop de km jai pris une A3 tdi et en voyant l'arrivé d'un diesel sur une TT sa me donne envie mais si sa peux gener certain .

[H2G]

Dieu sait si je déteste le diesel mais que le TT sorte en TDI ne me gène absolument pas.Du moment qu'on peut encore l'acheter en essence,tout va bien...

[seb77]

@ Erty

 

tu as une info source pour dire que le bloc 170 sera en rampe commune ?

[fioung]

c'est ecrit partout dans les journaux :P

 

rampe commune 2.0 TDI 170cv

 

The new common rail injection system is equipped with highly modern piezo injectors, whose eight-hole injection nozzles can perform up to five distinct injection sequences per cycle. This fine degree of modulation creates a modest pressure increase in the combustion chambers, resulting in a significantly reduced noise level. The system pressure of 1,800 bar allows fuel to form a fine dispersion, enabling precise, highly efficient combustion.

 

[matiouse]

Je vais au salon de l'auto à GENEVE cette semaine en PRESSE VIP je vous tients au courant avec bien sur des photos à l'appuit mais je ne sait pas si mon APN va réussir à la prendre en tof sans BOUDER lui aussi...

 

 

Je vous tiens au courant... :bigthumbup:

[F7R]

"L’Audi TT Coupé 2.0 TDI quattro n’a dans ses sprints aucun mal à « semer » ses concurrents à moteur essence et passe de 0 à 100 km/h en seulement 7,5 secondes. "

 

 

ça m'étonnerait fortement ça :rolleyes:
