Personally, I'm waiting for the economy figures, too. The new Fit apparently isn't as good in the real-world in terms of economy as the old. Honda, locally, used to do eco-runs, touting economy results between 50-70 mpg...
in the city... for the old car. On a hypermiling trip, they've gotten over 1,400 kilometers out of one puny 42 liter tank... (around 77 mpg... with the iDSi engine). They held a few eco-runs with the new ones when they came out, but figures were disappointingly in the 40 mpg plus range, only.
I haven't driven the new Fit, but is it really that bad compared to its predecessor? I really liked the previous Fit Sport, felt it was adequate or better under most circumstances, and was really pleased with the performance I was able to pull out of it on several test-drives. The engine was happy to rev, the gearbox was nice and tight, and the car was easy to read when I tossed it into a corner.
I would personally assume that the CR-Z would drive much more like the old Fit, but, I guess I'm a shade on the wrong side. I'll have to see one in person, give it a drive.
The new Fit is targeted at the mass-market. Thus, it suffers from Scion xB syndrome... make it bigger... make it more comfortable... make it heavier.
That said... it's not
that much heavier, and it's still a cracker to drive compared to four-door "compacts". The new engine feels pretty healthy, the steering is miles better than the annoying electric rack of the old car and the suspension isn't as rattly over bumps.
But... the softer ride and mass market appeal mean that it's not quite as tidy in a corner. It leans more, understeers more and doesn't feel quite as adjustable. In corners where I've dived into, apex-perfect at, 70 mph, four-wheel drifting, in the old Fit, the new Fit will simply scrub wide, leaning onto its outside front wheel and "pushing".
And if you've driven the new Fiesta or the current Mazda2, you'll be sorely disappointed with the current Fit's athletic abilities. Especially since the Mazda2 is just about as joyful to drive as the first-gen Fit (with better steering).
It's worth noting that the Fit feels a fair bit more spacious than either, despite on-paper stats claiming otherwise, and has a bigger cargo bin... and for people who want four seats and a trunk that can swallow an elephant, there is still no substitute.
