Updating previous review (see Greener with Style 4/05): City/Suburban driving 24.5 to 27.5 mpg and highway driving (55 to 65 mph in hilly Oregon) 33 to 34 mpg. Realistically we could have saved a lot more by buying a strong 4 cylinder Accord, but our reasons for buying the car were not driven by only the dollars spent. The car is a joy to drive. Again I would emphasize you need to test drive it fully warmed up in a variety of conditions. Some people may actually be annoyed by the engine shutdown on stops and cylinder shutdown/restart. Electronic steering feels like it 'hangs' sometimes. My wife drives a Civic Hybrid with about 44 mpg but lacks the comfort and power of the Accord (lucky me).
As before: the technology behind the hybrid system, power, relative economy for a six cylinder (40 to 60% better than my 2001 Highlander V6 with more power), air bag safety, XM Radio is pretty cool too
Automatic lights, heated mirrors, mini spare would be nice additions along with very minor improvements in the electronic steering, keep in mind that this car will not save much (if anything at all) if you tend to race from light to light or have to drive in creeping bumper to bumper traffic
