What does the "TSI" signify?
Thyroid stimulating immunoglobulin or TSI for short (1) is the name of a blood test which is used to identify the presence of autoimmune disease in those with hyperthyroidism.

What does TDI and GTI stand for?
The original use stood for the Italian words Gran Turismo Iniezione.

Direct injection results in more efficient fuel ...
What is initialism in cars?
Manufacturers regularly use initialisms to identify the engines they put in their cars. This applies to petrol and diesel engines; you may have seen ‘TDI’, ‘FSI’ and ‘TSI’ in brochures and on websites, to give just three examples.
Is a TSI engine turbocharged?
Both are turbocharged but the newer TSI engines feature reliability improvements, including a switch to a timing chain from a cam belt. They’re also lighter, have a better fuel injection system and benefit from cooling improvements.
Which cars have a TSI engine?

What is a TSI engine?
TSI engines combine what Volkswagen has learned from TDI diesel tech and FSI Fuel Stratified Injection engines. TSI is available on an increasing number of our cars, from Polo to Passat. The benefits are quite clear when you compare them to older MPI systems: high specific torque is available from much lower revs and maintained at most rpms. This makes cars equipped with these engines more lively at lower revs, which in turn makes them more economical and cleaner.
What cars use TSI engines?

What is the driving principle behind Volkswagen?
The first driving principle behind the system is direct fuel injection. Volkswagen uses the latest injector technology to shoot the fuel directly into each of the cylinder’s combustion chamber at higher pressures. This ensures less pumping losses and a more efficient combustion, thus increasing fuel economy.
Does Volkswagen have a TSI engine?
Volkswagen never stops inventing new technology to make their TSI engines competitive. The older 1.4 122 hp pioneered a new injector system with six fuel bores, while the latest 1.4 140 hp has a better cooling system and Active Cylinder Management, which is basically an advanced form of cylinder deactivation.
