P.S. The LEAFís air conditioning is a totally different situation from its heating. After living with the car throughout one of the hottest summers on record, with many days over 100 degrees (largely thanks to our burning of fossil fuels), I found the LEAFís cooling to work as well as virtually any ICE carís and it uses surprisingly little battery capacity. Itís a mistake to lump together ignorance-based gripes about an EVís heating and cooling performance.

This is a very poor post. The reason for the new heating features is so that you can feel warmer using less power by heating the seats and steering wheel directly, instead of using more power to heat the air in the car, much like the way floor heating works in homes. There is no comment on how well this works nor a comparison to the version of the car without these features, and the mileage range gauge was used to measure the power used to heat the car. Folks, we LEAF owners love 99% about our cars, but we know the range ďguess-o-meterĒ is a poor indicator of battery capacity remaining and is probably even worse for measuring capacity used. You canít be serious that this is scientific! Yes, you need to understand the car a lot better to assess its heating and energy performance, and yes, it takes a LOT of energy to heat the air in ANY car. The reason itís easy and ďfreeĒ in an internal combustion engine (ICE) car, is because itís so expensive. You are ALWAYS paying a LOT of money to heat your inherently very inefficient ICE car--in all weather conditions, whether you want heat or not. Your engine heat is just as abundant and expensive when itís 100 degrees outside! With a car as efficient as an EV, you have to actually pay for what energy you use. (How novel!) Unfortunately, heating the air is slow and will use battery capacity. Thatís why LEAF owners have learned itís best to preheat the car via their charge stations before disembarking, and thatís also why Nissan added the direct heating package. It would have been useful if this article lived up to its goal of assessing those features relative to the air heater only.

The projection TV analogy may be a good example of what I've been preaching. When projection TVs came out, I thought they were atrocious. It seemed unbelievable that anyone would buy them. I thought first of all, you need a LOT more image resolution than NSTC provides. And secondly, a direct view solution would be much better, higher contrast, higher lumens. So did I gush over NTSC rear or front projection TVs? No. But I was super interested in developments along the lines of HDTV and digital TV. Same with electric cars. I think using a battery as your main energy sotrage device is not going to be the long term, no-apologies solution. On the other hand, generating the electricity on board, from a source with lots of energy per weight and volume, such as a hydrocarbon fuel, THAT will be what would turn me on.

Exactly my feelings after driving it for 2 weeks about 80 miles a day.It is a nice car and I enjoyed driving it.Some people are just too set in their ways.Technology changes and we should support it. Good choice Brian!

No, they are too light for a snow ,because batteris are quite heavy,although new "compact" gasoline cars and all the new tin-can cars and too light for a snow.A distance of 100 miles is plenty for most of people , plus you can recharge it (" if you go somewhere after work") in a half hour.I just wonder how Socialist bubble got in there? Do you own a lot of stock in oil? Are New York , Houston, Dallas and Orlando the "Socialist bubbles?" Do you know that in "warm" states you have to wait for Leaf delivery for 2-3 months? They cannot make enough of them. Get in touch with a reality.In 10 years most of the cars will be electric and "smokestacks" will be seen in museums.By the way....in "Socialist bubbles" (I assume that you meant Europe) they use fast ELECTRIC trains.

"42F is cold weather? No wonder electric vehicles aren't catching on - none of the (mostly Michigan based) executives or engineers involved would want to take one home for a test drive, at least in the winter." +1 These cars are also too light to drive in snow. WRT the previous post: So what if the average American only drives 40 miles to work. Maybe the "average American" might want to go somewhere after work. There are a lot of Americans that commute very long distances just to get to whatever job they can find. Electric cars with a 40-100 mile range may be ideal if you live in a tightly-controlled Socialist bubble.

Hi Bert, Back in 2005, I chose a diesel wagon over a hybrid because the highway mileage was the same and I could haul a lot more in it. For my needs it was a better choice. I wrote about it in a previous life which you can read here: http://www.examiner.com/automotive-in-boston/diesel-is-back

Average American drives to work 40 miles and it looks like leaf is perfect. No Leaf is not powered only by sourced described by you (and whet's wrong with naturel gas???)We are a bit behind the world in solar. Germans derive 40% of their electricity from solar.We didn't touch 5% yet , however we do have nice wind turbine farms (and people complain about noise)The main point is that is it impossible to make everyone happy.Be positive .ALL new discoveries take time and are expensive in an initial stage.As far as flying cars they exist and you can google them.And....there is no conspiracy with limiting your free movement.First cars were electric and moves 20mph and lasted about 40....until Deimler visited Ford, but it is a long story....maybe some other time.

Help being the operative word. When you calculate the KWH output of a hood size solar panel, it's really disappointing. Keeping a battery charged may be doable.
