The turbocharged 1.8 TFSI has a displacement of 1,798 cm3 and achieves its peak torque of 250 Nm (184.4 lb‑ft) across the rev range of 1,250 to 5,000 rpm. At part loads, an additional manifold injection system supplements the FSI direct injection, to cut emissions. The Audi valvelift system varies the stroke of the exhaust valves, improving the engine’s response. A compact rotary valve module for thermal management and the exhaust manifold integrated into the cylinder head both play a major part in the four‑cylinder engine’s efficiency.
The TT Coupé with six‑speed manual transmission accelerates from 0 to 100 km/h (62.1 mph) in 6.9 seconds, or in 7.0 seconds with the optional six‑speed S tronic, and continues right up to a top speed of 241 km/h (149.8 mph). In the case of the Roadster, the corresponding figures for the standard sprint are 7.2 seconds with manual transmission and 7.3 seconds for the S tronic version. The top speed for both combinations is 237 km/h (147.3 mph). The 1.8 TFSI Coupé version covers 100 kilometers (62.1 mi) on an average of only 5.7 to 6.0 liters of fuel (129 – 138 g CO2 per km) (33.6 – 30.9 US mpg; 207.6 – 222.1 g/mi); the TT Roadster 1.8 TFSI achieves this on 5.8 to 6.1 liters (132 – 142 g CO2 per km) (33.1 – 30.5 US mpg; 212.4 – 228.5 g/mi).
As well as the new entry-level engine version, Audi supplies the new TT generation with a choice of three two‑liter engines: The TT 2.0 TDI ultra with 135 kW (184 hp) and 380 Nm (280.3 lb‑ft) of torque needs only 4.2 liters of fuel per 100 kilometers (56.0 US mpg). That corresponds to CO2 emissions of 110 grams per kilometer (177.0 g/mi) and therefore represents new best-in-segment fuel economy. Then there are two versions of the 2.0 TFSI: In the TT, the supercharged petrol engine develops 169 kW (230 hp) and 370 Nm (272.9 lb‑ft) of torque; the power output of the TTS is 228 kW (310 hp) and 380 Nm (280.3 lb‑ft). The Coupé sprints from 0 to 100 km/h (62.1 mph) in 4.6 seconds.
Even the basic version of the sports car comes equipped with all the strengths of the new model generation – a purist, sporty character, systematic lightweight construction, striking design and dynamic suspension. Nor are there any constraints on equipment: The sport seats with integral head restraints are fitted as standard, along with progressive steering and the Audi virtual cockpit.
Specifically the interior of the new TT generation has caused a major stir since its world debut at the Consumer Electronics Show (CES) in Las Vegas at the start of 2014. The compact sports car has already collected an assortment of awards – including “Design Innovation of the Year” and “connected car of the year”. It has earned these accolades also thanks to optional high‑end features such as Audi connect, for a high‑speed Internet connection, the Audi drive select driving dynamics system, and assistance systems such as park assist with a reversing camera.
Fuel consumption of the models named above:
Audi TT Coupé:
Combined fuel consumption in l/100 km: 4.2 – 7.3 (56.0 – 32.2 US mpg)**;
Combined CO2 emissions in g/km: 110 – 169 (177.0 – 272.0 g/mi)**
Audi TT Roadster:
Combined fuel consumption in l/100 km: 4.3 – 7.5 (54.7 – 31.4 US mpg)**;
Combined CO2 emissions in g/km: 114 – 174 (183.5 – 280.0 g/mi)**
**The fuel consumption and the CO2 emissions of a vehicle vary due to the choice of wheels and tires. They not only depend on the efficient utilization of the fuel by the vehicle, but are also influenced by driving behavior and other non-technical factors.
