 I was very disappointed with the Sonata Hybrid.They advertise 40 mph highway, but I get about 32; the internal computer says I get about 35, though.When I asked about the discrepancy between my actual fuel consumption and the sumputer's estimate, the dearship told me the computer was more accurate than the actual (not sure how that's possible).The interior is also very constrictive and not comfortable for anyone over 6' for anything more than about 30 minutes.The electric motor is very weak, only operating up until about 10 mph, and only kicking in after that during coasting.The accelerator is also very unresponsive, sometimes taking up to two seconds to kick in.
