A few things are getting more aerodynamic, but sadly the true innovation and real fuel savings are not coming to the consumer like they should.

The above post is in regards to the new Honda Insight, and specifically how it is getting less EPA rated fuel economy than the Honda Civic Hybrid (both are hybrids).
Add into the mix, my "large" Chevy Impala, getting great fuel economy on the highway, and we have 4cyl smaller cars not able to even break 30 mpg??? Come on, aero is one thing, proper balance of hp/weight with the right gearing, right design, and a caring foot are the other things needed to get us rolling with less fuel. Too bad we cannot give the bigwigs running around in Excursions and BMW 7 series(just a couple of examples, no picking meant) a 20 dollar per week fuel allowance and see how they deal with thier beloved fuel suckers.
