Here are the engine options for the 2011 Jetta:
* 2.5L 5-cylinder: This was the base engine option.
* 2.0L Turbocharged 4-cylinder: This was available in the Jetta Sport and Jetta GLI models.
* 2.0L TDI Clean Diesel: This was available in the Jetta TDI model.
Once you tell me the trim level, I can tell you the specific engine size for that model.
