This article from Newsweek (also reprinted by MSNBC) - Imagine: 500 Miles Per Gallon - unfortunately misses a number of key important points.
Firstly, hybrid cars are currently worse performing than diesel cars. They burn more fuel. They cost more. Their batteries are expensive and wear out after 4 years - at a large cost to the environment. They pollute more even if you don't take into account the batteries - modern diesels from Europe put out less waste products than modern gasoline engines seen in the US.
Secondly, battery technology isn't accelerating that fast. It hasn't accelerated anywhere near where we'd like it to. Look at laptops for proof of this - they're having trouble keeping up. Because of this, fuel technologies will need to get better - and they're not keeping up all that fast. The biggest advance in the last 50 years was the new design, impressively efficient - yes, you guessed it -
Will a hybrid diesel work? Maybe. Will we get around the battery issues? No time soon. Besides, Buzz Aldrin already tried to point out that improving battery life would be an important step forward as a political campaign platform in the 70s. No-one bought it. Sure, the climate might have changed, but has it changed that much?
All in all... don't go for a hybrid yet. Even with the latest models, diesels are better for the environment. If you really care about that kind of thing, buy a diesel. You'll spend less on gas than for a hybrid too...
