"considering the rising price of gas, I would have to say all the hybrid cars get my vote"
Palladium, you forgot the original hybrid; Honda's 2-seat Insight. An impractical 'only' car for most U.S. buyers but no other model sold here gets EPA 60 city, 66 highway M.P.G. (manual transmission model; CVT
automatic model rates somewhat less). Of course real world average M.P.G. is more like mid-fifties and this car is cramped, noisy, slow and handles somewhat skittishly, due to skinny, low-rolling resistance tires. I'm one of the few Americans who could likely live with all of this for my 'only' car.
And if $5.00+ per gallon gas prices are coming soon, I may just do that. However, most Americans need and demand more car so its sales have been very slow, here, unlike the vastly roomier and far more comfortable Toyota Prius .

Superfly, although these are all good cars and relatively frugal, considering their size and power, most of them are still V8
's, something I'd avoid if gas prices keep rising. I'd instead choose the 6 cylinder models of these cars that offer one although half of them don't. Nothing wrong with power except that it's costing more to have it, these days. I'd go for a 300 Touring model with the 3.5L
V6; it's powerful enough. Despite its cylinder deactivation feature, the Hemi is sure to get less real world mileage than the six, despite not much poorer EPA ratings. These high gas prices may abate somewhat after the Katrina-related refinery disruptions ease but I'd prefer to go for better M.P.G. in any model I'd have for a few years; historically, gas prices ultimately keep getting higher.
