This is just a thought experiment at this point, and probably will remain so. In the back of my mind I have the idea that when my old SUV finally gives up the ghost I might rip out the internal combustion drivetrain and convert it to an electric vehicle, possibly with a removable range-extender generator. Setting practicality aside for the moment, can you help me envision what this would involve? [more inside]
I've become mildly obsessed with trying to improve the fuel efficiency of my old truck. I've already done all the basic things and I realize that I'm fighting physics at this point, but what else might I consider if I wanted to make a bit of a hobby out of it? [more inside]
Our vanpool just switched to a 2014 Dodge Grand Caravan. It's a FlexFuel vehicle and we'd like to know when/if it makes sense to use E85 fuel. We live in Minnesota. Our typical commute is 40 miles at highway speeds. Environmental concerns will be weighed, but so will economical ones.
I have an ongoing (friendly) disagreement with a guy I know. He drives a Toyota Prius because it's "better for the environment" than buying, say, a new Subaru Outback. Fine. I get that. But my argument is that it would be even better for the environment if he were to buy a used Subaru Outbook. I've never run the numbers, but it seems to me that if you were to buy the most gas-guzzling of used cars, the fact that you're not causing a new vehicle to be produced would make up for the lack of fuel efficiency. Can you help support my position? Or, alternatively, give me solid numbers as to why I'm wrong? Are there websites that have run analyses on this sort of thing already?
How hard/expensive is it likely to be to get a ten-year-old Jeep to pass California emissions standards? [more inside]
Why is biofuel diesel, instead of standard gasoline? [more inside]
What are the most efficient cars readily available in the United States? Mileage, fuel & emissions and size are all important criteria.
I love my car, but am becoming increasingly concerned about gas mileage and environmental responsibility. It isn't a guzzler, but I know I could do better. What are your experiences with diesel cars? [more inside]
