The Jetta, it turns out, is nearly as much car as the W8 Passat:

I think the performance tests here are bit goofy, given the altitude, but it's interesting to see physically how the Jetta matches up to the Passat. Spoiler alert: it's large.
After a few hundred miles, though, I can report that we're averaging over 30 mpg in almost entirely urban driving, which is probably not something that a W8 Passat could claim.
