The dynamic styling of the exterior design is carried through into the interior of the TT. It gives the impression of a tailored suit – the cockpit is perfectly tailored to the driver, with the center console canted slightly toward him or her. The design of the short shift lever, the round air vents and the dials of the automatic climate control system (standard in the 2.0 TFSI) follow TT tradition.

The instrument cluster is housed beneath a dome that can be trimmed in leather as an option. Typical for the TT are also the speedometer and tachometer dials recessed into tubes, supplemented by a digital speed indicator in the display of the driver information system. When the ignition is switched on, the dials briefly turn all the way to the limit and then fall back to zero. The ergonomics are clear and the fit and finish is uncompromisingly precise – just like always with Audi.

The new three-spoke sports steering wheel, which is adjustable horizontally and vertically, fits snugly in the hands. Its thick rim, covered with high-grade Nappa leather, is flattened at the bottom. An optional multifunction sports steering wheel is available with convenient controls for the radio and telephone. In models with S tronic, the steering wheel also includes two shift paddles.

The driver’s and passenger’s sport seats offer a deep, sporty position, good comfort and firm lateral support. Options include a four-way lumbar support, power seats and heated seats. The Audi exclusive program from quattro GmbH offers manually adjustable bucket seats covered with black Fine Nappa leather.

A series of fine details now imparts the interior with even more gloss. New aluminum-look applications shine on the steering wheel, the center console and in the door liner. Elegant accents on the air vents, for example, are provided by rings, frames and strips in high-gloss black. The aluminum strip above the glove box door is now brushed gray.

Three new interior colors – nougat brown, titanium gray and garnet red – join the existing colors of black, chennai brown, magma red and luxor beige.

The leather seat covers are specially treated to reduce thermal heating by as much as 20 degrees Celsius (68 Fahrenheit) when the TT is parked in the sun. This treatment is available for both the Roadster and the Coupé.

Cloth seats are standard in cars with the entry-level engines. The 2.0 TFSI comes standard with a leather/Alcantara combination and heated seats. For custom specifications, Audi offers Valetta, Fine Nappa, Leather/Alcantara and Impulse leather packages. The Impulse seat covers, available in black or chennai brown, have thick, boldly offset seams. They achieved cult status in a similar form in the first-generation TT Roadster.

Engines

Audi offers a choice of three four-cylinder engines with turbocharging and direct fuel injection for both the TT Coupé and the TT Roadster. The two TFSI gasoline engines and the TDI combine sporty performance with groundbreaking efficiency – their fuel consumption figures have been reduced by up to 14 percent. All three engines work with a recuperation system that recovers energy during braking and coasting phases and stores it temporarily in the battery.

The TFSI engines

New in the TT engine lineup is the 2.0 TFSI with 155 kW (211 hp), which replaces the 2.0 TFSI with 147 kW (200 hp) and the 3.2-liter V6. The turbocharged four-cylinder engine, in which the Audi valvelift system (AVS) varies the lift of the exhaust valves, develops 350 Nm (258.15 lb-ft) of torque. With a manual transmission, it accelerates the Coupé from zero to 100 km/h (62.14 mph) in 6.1 seconds on its way to a top speed of 245 km/h (152.24 mph). Audi offers an optional drivetrain with the six-speed S tronic and quattro permanent all-wheel drive. In this combination, the standard sprint from zero to 100 km/h (62.14 mph) takes just 5.6 seconds.

Equipped with a manual transmission, the TT 2.0 TFSI consumes only 6.6 liters of fuel per 100 km (35.64 US mpg) in the European test cycle. Its CO2 emissions are 154 g/km (247.84 g/mile). This represents an improvement of 1.1 liters/100 km, or 14 percent, over the previous engine, which an international panel of journalists had honored as “Engine of the Year” multiple times in a row since 2005.

The 2.0 TFSI is a member of the Audi 888-series of engines. These embody the philosophy of downsizing: the substitution of engine displacement with forced induction. The crankcase of the long-stroke engine, which displaces 1,984 cc, is made of cast iron, which offers good acoustic damping, yet weighs only 33 kilograms (72.75 lb).

Its rigid basic structure helps to eliminate drumming and vibrations. Two balance shafts counter-rotate in order to eliminate the second-order free mass forces.

The chain for the balance shafts has also been optimized for quiet running. A second chain drives the oil pump, which uses volumetric flow control and two-stage pressure to save roughly 0.2 liters of fuel per 100 km. A third chain drives the two camshafts. The intake camshaft can be steplessly rotated 60 degrees relative to the crankshaft, and its actuator reacts particularly spontaneously.

The gasoline direct injection technology developed by Audi harmonizes perfectly with the turbocharging, because the evaporation of the strongly swirled fuel cools the combustion chambers. This enables 9.6:1 compression – a ratio that provides for high efficiency. The injection pressure in the common rail system is 150 bar. Six-port injectors precisely distribute the fuel within the combustion chamber.

A water-cooled turbocharger is responsible for filling the cylinders. An optimized turbine wheel improves its initial response at low engine speeds. The lightweight and compact intercooler also achieves a high degree of efficiency. In the aspiration system, the charge motion flap generates turbulence to ensure the production of a high-quality, homogenous mixture.
