A (non-plug-in) hybrid has been good for me; quiet on electric power on city streets, and can do over 400 miles without refuelling. It claims to be in EV mode over half the time when commuting.
Fuel consumption is 65 mpg compared with 45 mpg in a similar petrol-only car I had 10 years ago.
Electric only would be nice, if I could afford one which could manage 300 miles minimum, accounting for cold weather, battery wear and manufacturers' lies/exaggerations.
Get a plug-in hybrid. If you're actually getting 65mpg, you're easily going to get the manufacturer's specs for electric range. (This one sort of ticks me off, because it's criminally misreported in the mainstream media... it's like people aren't aware the EPA exists or think they're failing at their jobs...)
When it's time to replace the current car I'll look into that again, but not yet.
I am actually getting 65 mpg on occasions when I'm not in an hour-long traffic jam in freezing weather (then it's 50-55), but I'd forgotten about the difference between Imperial and US gallons, so 65 would be 54 for Americans.
