What is faster, TDI or TSI?
The TSI loves to rev and delivers a decent shove of torque from around 2,500rpm, while the TDI likes to stick below 4,000rpm but delivers more torque from 2,000 rpm – the result is the TSI is easier to thrash, and faster overall, but the in-gear performance doesn’t feel as strong as the TDI. On performance, the TDI is a few ticks slower than the GTI in acceleration, and in our handling tests.
