I've never driven one but I've looked into it and I don't think it's the best solution. I'd been thinking of buying the Escape hybrid when it becomes available, but after learning more about hybrids I am no longer very impressed. I would prefer turbo-deisel as a fuel efficient power source. The Germans make great turbo-deisels that give good performance and good fuel economy. The electric hybrid only provides marginally better all-around fuel economy (better in the city, about the same on the highway) but you have the complexity of the hybrid. Also, there's about a $6500 repair bill waiting when the time comes to replace the NiMH battery pack. That means greatly reduced resale value as the car gets older. IMHO hybrid development is primarily motivated by the auto manufacturers' political concerns, not by the consumers' needs. The auto companies know that one day the greens may put deeper restrictions on fossil fuels, and these hybrids bring them one step closer to the all-electric car. In other words, the cars are developed to make government bureaucrats happy, not to give you the best possible car.
If all the money spent to develop hybrids had been put into turbo-deisel we'd all have better options available now.
