When Hybrids Do (And Don't) Make Sense 720
prostoalex writes "Recently NPR, CNN Money and Wall Street Journal Online have all dedicated some time and space to discussing hybrid vehicle pros and cons. It seems that hybrids do not make much financial sense if (a) you're buying after getting yourself into a debt with not really good interest on a car loan, (b) your battery requires replacement after being out of warranty, (c) your daily commute is not too long, so the price markup you pay for a hybrid does not translate into long-term gas savings." From the CNN article: "They may make a social statement you're interested in, but if you want to save money because of rising gas prices, you're heading down the wrong road, at least for now."

Diesel efficiency (Score:4, Insightful)
This is a very common misconception. Diesel fuel is denser than gasoline. When you correct for mileage per fuel mass or (even better) per carbon output, much of their advantage on paper fades.
Diesel engines are still slightly more efficient than typical gasoline engines, owing to the higher compression ratios used by the Diesel ignition process. The higher combustion temperatures, however, produce nitrogen oxides, which are a local pollutant. And of course a poorly tuned Diesel (or, often, just a cold one) generates a ton of particulate ("soot") emissions -- another local pollutant.
And remember that Diesels idle very inefficiently (they have bigger and heavier pistons, and a finicky ignition mechanism that can't be run as lean as gasoline), whereas a hybird will shut down the engine and idle with no emissions whatsoever (well, minus battery drain due to the air conditioner, etc...).
The best general advice that I've read is that a Diesel makes the best environmental choice for a long-haul vehicle that rarely idles, or for rural areas with little sensitivity to local pollution. They make rather poorer choices in the urban commute environment.
