Audi is extending the engine range in the TT model line-up. From next July, the compact sports cars will also be available in a 1.8 TFSI version developing 180 bhp. The new entry-level engine version of the Audi TT Coupé will be available from €45,615 and the TT Roadster for €47,815.
The turbocharged 1.8TFSI has a displacement of 1,798cc and achieves its peak torque of 250Nm across the rev range of 1,250 to 5,000rpm. Uniquely, 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 kph in 6.9 seconds, or in seven seconds with the optional six-speed S-Tronic, and continues right up to a top speed of 241 kph.
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 kph. The 1.8 TFSI Coupé version covers 100 kilometres on an average of only 7.0 to 7.6 litres of fuel; the TT Roadster 1.8 TFSI achieves this on 7.1 to 7.7 litres.
