Correct me if I'm wrong, but in the recent Impreza testing didn't the manual achieve around 9L/100Km vs 10L/100Km in the CVT? The CVT states better EPA, but the real world tends to change that - I find more cars with manuals coming out with better average numbers, even though they have lower EPA's. This surprises me, as a fan of manual transmissions I tend to drive more aggressively (because its more fun) than I do in auto cars.
Aside from that, I don't see too many gas powered compact cars that average much better than 9L/100Km on the open road. The new Elantra may be better, but most of the real-world numbers I hear are at best around 9. My 2003 Protege5 is between 10-11, although it isn't really relevant in the modern car comparison.
