According to a recent study performed by Plug in America, Tesla's battery packs in its Roadster model are retaining more of their capacity than what Tesla had initially thought.

Battery packs in Tesla Motors' Roadster electric cars will retain an average of 80- to 85-percent of capacity after 100,000 miles driven, according to a study published by Plug In America, the nation's leading plug-in vehicle advocacy organization. The finding, released at the Teslive Tesla users conference, bests initial projections set by Tesla Motors in 2006 which suggested a 70-percent capacity retention after five years and 50,000 miles driven, said Tom Saxton, Plug In America's chief science officer.

"Our study also found no discernable effect...

Tommyguns45 - "What's the difference at paying at the pump for high gas or high utilities for plugging in at home."

Because, typically, cost per mile is less for electric than gas.

Also, some of our electricity comes from hydro, solar, wind or other renewable sources, with more on the way.

it gets me how most people just grumble about our energy concerns without offering at least some interesting ideas on how to control our energy future. complaining has become a national pastime. but at least offer an idea of who to help the energy situation.

These overpriced golf carts are still a waste of money. In California, we don't even have enough electrical power for all businesses and homes without adding cars to the grid. They cost far more than the money you will ever save in gasoline. Range is too short and time to charge is too long. Rechargeable batteries are expensive and never last very long. Anyone who has owned a cell phone, laptop, GPS, rechargeable razor, etc. knows the battery needs to be replaced long before the product needs to be replaced.

Why do folks like myambro keep repeating the same foolish drivel about the Volt only goning 40 miles at a time? The Volt may only go about 40 miles on the "All electric" mode but has a range closer to 380 miles with the full tank of gas and a full charge.

But in more local driving, "Volt drivers who charge regularly are averaging 900 miles, or about a month between fill-ups.†"

And the Nissan Leaf's range is closer to 78 miles.

Yay for Tesla. Meanwhile the unwashed masses have to make do with the Leaf and the Volt. How many of us can afford a $40,000 car that can only go 40 miles at a time? (WWII German submarines could go 90 miles on a single charge)

I believe Traps has a great product, but their larger challenging will trying to get the country to change its policy of forcing the consumer to buy through a middle man i.e., a dealership.

Improved battery performance is always a big plus, but EV's aren't going to have a MAJOR impact on vehicle sales until battery technology gets exponentially better. Sounds like there may well be a lot of satisfied Leaf owners (16 M miles a year), but the Tessla is unaffordable from what I have heard. A rather significant difference.

Tesla figured out Li-Ion batteries (unlike GM/Toyota)
But at a very high price.

I can't see any reason why the same battery pack can't be used in other EVs.

That is good news, but notice they don't mention colder climates, which may be due to lack of people driving their roadsters during the winter, but we'll see how the batteries perform in the cold, I'm seeing more of the Tesla sedans in Chicago.
