Tesla Roadster CAR review | Road Testing Reviews | Car Magazine Online
"The Tesla is set up with no toe-in or wheel camber for maximum efficiency and therefore maximum range..."
And from Autoweek,
"There was no toe dialed into the setup, meaning the
wheels and tires were all pointing straight forward to reduce as much rolling resistance as possible. This felt a little strange at first, but the feeling disappeared within a few miles, and the Lotus rack-and-pinion steering felt perfectly fine the rest of the day; it just wandered a little more than usual from on-center."
As far as I know, both toe-in and camber are adjustable. Maybe this is the suspension tuning they are referring to. To learn about camber and toe-in, you can go to this website:
