The 45 TFSI engine has been specially developed for the requirements of the TT. To attain 147 kW of power, the crank drive, cylinder head and inlet valves, among other things, have been modified. In practice, the 45 TFSI has impressive torque of 280 Nm over a broad engine speed range from 1,800 to 5,000 rpm.

FSI technology and turbocharging make such an excellent combination because the evaporation of fuel directly within the combustion chamber in FSI engines removes heat from the intake air. This allows a higher compression, significantly improving engine efficiency. It also solves an old problem in all turbocharged engines – a high tendency to knock at high boost levels. The integrated turbocharger exhaust manifold module ensures optimum turbine efficiency, resulting in excellent utilization of the exhaust energy. This achieves both a high power output and optimum engine responsiveness, ultimately helping to reduce fuel consumption and exhaust emissions.
