Body and interior
The body of the TT Coupé is based on hybrid Audi Aluminum Space Frame (ASF) technology. Lightweight aluminum is used at the front of the car back to the B-pillar, with steel panels used at the rear. The mix makes it possible to finely balance the axle loads and keep the overall weight low. The rigid and safe bodyshell weighs just 206 kilograms (454.15 lb). The TT 1.8 Coupé TFSI weighs a mere 1,240 kg (2,733.73 lb), a good 100 kilograms (220.46 lbs) less than its competitors.

The interior offers dynamic elegance and superior workmanship. The leather seat covers are specially treated to reduce solar heating by as much as 20 degrees Celsius (68° Fahrenheit). The 2+2-seat coupé is a sports car with a high degree of everyday practicality. The split backs of the rear seats fold down, expanding the trunk space beneath the long hatch from 292 to 700 liters (10.31 – 24.72 cu ft).

Drivetrain
Audi offers the TT Coupé with three four-cylinder engines with turbocharging and direct fuel injection. The two TFSI gasoline engines and the TDI combine sporty performance with high efficiency for impressively low fuel consumption figures.

The Audi TT 2.0 TDI consumes on average just 5.3 liters of fuel per 100 km (44.38 US mpg). Its 125 kW (170 hp) of power and a brawny 350 Nm (258.15 lb-ft) of torque provide for dynamic performance.

The engines:

• 1.8 TFSI with 118 kW (160 hp)
• 2.0 TFSI and 2.0 TFSI quattro with 155 kW (211 hp)
• 2.0 TDI quattro with 125 kW (170 hp)

A six-speed manual or a six or seven-speed S tronic transfers power to the wheels regardless of the engine. quattro permanent all-wheel drive is available as an option for the 2.0 TFSI; it comes standard with the TDI. The heart of the system is an electronically controlled hydraulic multi-plate clutch.

Chassis
The front suspension of the Audi TT features McPherson struts, with aluminum components used to keep the weight of the unsprung masses low. Thanks to its electromechanical drive, the power steering is highly efficient. The trailing arms of the four-link rear suspension are designed with an eye toward comfort. The connections to the three transverse links per wheel, on the other hand, are rigid in order to direct lateral forces into the body with precision.

Available as an option with all variants of the TT is the variable Audi magnetic ride shock absorber system, another high-tech feature. A computer switches the adaptive suspension between two settings as desired by the driver. The optional sport button can be used to adjust the characteristic of the gas pedal (with manual transmissions), the servo boost for the steering and the engine sound in two stages.

Equipment
All TT models come with a generous array of standard equipment, including the on-board computer with efficiency program. Options include the two navigation systems and the Bose surround sound system.

The Audi TT Roadster
The classic cloth top of the TT Roadster is an expression of Audi’s lightweight construction principle. It contributes to a low center of gravity, fits harmoniously into the design line and takes up little space when open. A manual top is standard. The automatic top includes an additional acoustic mat and an electrohydraulic drive. It opens in 12 seconds, even while driving at a speed of up to 50 km/h (31.07 mph). The price list also includes a power net wind deflector for both versions of the top.

The TT Roadster is a pure two-seater. Two massive rollover bars protect the driver and passenger in the event of a rollover. Compared to the TT Coupé, its ultra-lightweight, largely aluminum body includes reinforcements in the area of the A-pillars, the sills and the bulkhead between the interior and the luggage compartment, yet it still weighs just 251 kilograms (553.36 lb). The luggage compartment holds 250 liters (8.83 cu ft) with the top up or down.

The engines and transmissions offered for the Audi TT Roadster are identical to those offered for the TT Coupé.

The engines:

• 1.8 TFSI with 118 kW (160 hp)
• 2.0 TFSI and 2.0 TFSI quattro with 155 kW (211 hp)
• 2.0 TDI quattro with 125 kW (170 PS)
