Took a 6-speed manual eco for a test drive and I have to say I was really impressed. My impression of the car was it was the best of a diesel and gasser together. Turbo spools up around 1400 rpm, it has enough torque to move it like a tdi because it's such a light car, and it revs to 6k rpm when you want to play boy racer. I always loved my diesels for all there torquey bark, but if you want to hole shot someone at a light, you'd better be sure you can get them before 3k rpm in second gear, because there's no bite after that. Even a little v-tech will get past you, since the tdi is running out of revs.
I'd looooove to see a 2.0 diesel in a chevy cruze. I was really close to picking up the 6-speed manual eco model this summer, but I decided to stick with the VW for another year. If the diesel actually happens, I'll be glad I did. If chevy offers the diesel cruze with a manual trans, i'll buy one. If they package the diesel motor with all the luxury junk and a slushbox auto trans, I'll pass. But then again, I don't actually believe they'll offer a diesel. Manufacturers like subaru, honda, toyota and even ford have been promising us diesels "next year" for the last 5 years... it's always gonna be "next year", just like chevy is saying now.
