TSI is our pioneering technology for petrol engines. TSI engines are compact, high-powered and use less fuel. TSI technology blends the best of our TDI diesel and FSI (fuel stratified direct injection) petrol engines to give you excellent driveability and outstanding fuel economy.
Is a TSI a turbo?
TSI is short for ‘Turbocharged Stratified Injection’ and essentially indicates that the engine is turbocharged.
Which is better TDI or TSI?
TDI engines will typically have better fuel economy compared to a TSI (especially if you do lots of long motorway journeys), as is usually the case with any diesel engine compared to petrol. TDIs tend to be more expensive to purchase though, and the fuel itself typically costs more per litre.
Are TSI engines any good?
The 2.0T TSI was a fairly reliable engine, but it does have a list of common problems. This article will outline the common VW engine problems and how to detect them. This engine uses direct injection to spray the fuel into the engine’s cylinders. The fuel injectors the piece that sprays the fuel.
