Just when Volkswagen launched its TDI Jettas back in the U.S. market, they've started planning on bringing back the Golf/Rabbit TDI's. A 1.6-liter TDI that will be capable of 62 MPG!
If you're not a fan of VW, then Volvo also plans on putting TDI versions of their C30, S40 and V50 out with a similar sized engine capable of 53 MPG.
If for some reason you still want a gas burner, then you may want to opt for a Toyota version of the Smart-for-two car, the iQ.
This little bugger has a 3 cylinder 1.0-liter gas engine(remember the Geo Metro?) that will get 50-55 MPG. There may be another engine option that they are kicking around that will yield 60 MPG. Of course, the biggest complaint here? Europe gets first crack at this market. Once again, the American consumer gets the shaft.
I'm not stackin' paper like I used to, so my options for buying are nonexistent.
