100K, deal. Sign me up.

Well at 2.7p per mile, and 0-60 in 3.8 seconds, it is kinda tempting :) I love that electric car makers have woken up to the fact no one will like them until they out perform the best of petrol... Just looking into the stats, there's no way petrol can keep up with what's coming... no physical gearbox (wheel drive), 96% efficient motors, massive torque from start... full charge in 10 mins (British Lightning tech) it's the end for petrol within 10 years I reckon...

Or, like you have a reserve can with gasolin, you `ll have an extra battery.

One problem! If you get a flat battery you are going to need some mighty long jumper leeds to get home.

Exactly!! do you not know that 90% of ALL media is owned by only 5 entities? This is how they control public opinion. I'm surprised they're still alive. Tessla died when he tried to prove and market his inventions because they would have destroyed current industries.

the EV1 did not die from lack of popularity

Eh would less pollution be a good enough reason

Thanks ReisendeEuropa I'll look into 'regenerative braking'.

There are so many factors to consider with this. Motor load, wind resistance, mechanical resistance, and the fact that 30% power will still accelerate the car. You use about 2-7% to maintain average highway speeds. A study several years ago showed that a large American pickup truck only needed around 15 horsepower(roughly 12kw) to maintain 55mph. 53kWh/12kW=4.41h run time. At 55mph this equals 242.55mi. I'm guessing this is very close to what the Tesla uses.

well at one third power the vehicle will be using 50kw and the battery capacity is 50kw/hour ie the battery can supply 50kw for one hour.
