The new Corsa comes with either as a 1.3CTDi (70bhp) common rail diesel engine or as a 1.7CTDi (100 bhp). The 1.3 is a joint Fiat/GM design but does anyone know if the 1.7 is as well, or is it a newer version of the old Isuzu engine?
I think the 1.7 is a development of the GM design with chain cam drive and 16 valve. Used to be the 1.7DTi then changed to CTDi.
The 1.3 is a Fiat design, received good reviews but I'm unsure if it has a cambelt or camchain.
