Actually, I brought up the project because the sub 2 second 0-60 was one of many impressive accomplishments.
The AWD setup with individual control of the torque on every wheel allows significant cornering, braking, and accelleration advantages. This wasn't done just to go in a straight line fast.
If the car were made ONLY to accellerate from 0 to 60, my guess is it would look significantly different. Go ahead, make a rail gun and see if you impress anyone on that team.
I think the motors are a big deal because they can deliver 50hp with full torque up to almost 10krpm. They are light enough that a hub-motor is actually practical in that it doesn't destroy suspension performance with unsprung weight.
Personally, I'd love the opportunity to visit and ask open-minded questions.
