1. The Electric motor in general is nearly 90% efficient. The gasoline engine is 30%
2. The Tesla uses no gasoline, just electric and batteries. When you charge batteries, they don't get heavier. When you fill up a car, it gets heavier. 3. Battery technology has gotten much better lately. 4. The Tesla is using "secret" technology that they're either trying to patent or have patented. A more efficient use of power. --- Andy Davies <[EMAIL PROTECTED]> wrote: > "it is six times as efficient and produces one-tenth > the pollution, all > while achieving the same performance and > acceleration" > > dream on - I just don't trust their figures - why > are their vehicle > efficiency figures better than three times the > opposition, *and* their > well-to-wheel figures better than two times?
