Audi RS3 (8P) Sportback 2011-2012

[JRodrigues]

Perhaps just for the record, audi used the R10TDI to further develop their common rail system for direct injection diesel engines, which VAG only introduced about 10 years after Bosch and Fiat had developed it and which is now standard on all modern diesel engined car.
Audi/VAG initially used the pumpjet for roadcars, which ultimataly proved to be inferior to the common rail system (noise, emissions, sweetness) That they still call it TDI just has to do with marketing, changing the name would be tantamount to admitting that they choose the wrong system to begin with....

What has TDI ever got to do with PD?!

What has TDI ever got to do with PD?!

Ever since VAG introduced their direct injection system for diesels they called it TDI. So the pumpjet (Pompe-Duse) was the first version of the TDI and they call the common rail systems that they are now using also TDI, obviously for marketing reasons.

TDI has been a VAG brand name since 1989--maybe it sounded better than "turbo diesel".

The Jetta engine.
