Sounds real mean in theory the tourque "line" (ie imagine the peak of a tourque curve in your normal supercar, double it and make it a horizontal line) is to die for.
The problem is that while lithium ion batteries make this vehicle very viable ( as there is no memory effect in the batteries so they can be discharged and charged at random) they still like all batteries have a limited shelf life. This wouldnt be to bad except the tesla has 11000 of what are essentially laptop batteries. Now last time i looked laptop batteries wernt cheap. What the tesla saves in fuel costs the customer will pay in three- four years in battery replacement costs.
