I ran my new 2010 Roadster S yesterday in my first ever autocross. I know, no pics it didn't happen. I will post video when I edit the footage. Although I didn't do very well (66 seconds) as I kept getting lost in the cones, My son (Blair) who races regularly also raced the Tesla and did 58 seconds. The fast time for the track was 51 seconds by a special built 800 lb race car (big go kart, huge wings) with a turbo'ed snowmobile engine. The fast Cobra replicars and Vettes were doing 52 seconds. I had two other problems besides getting lost. The brakes need work. The brakes started getting better as they started braking in but still not up to the task. I will be looking for some better pads. The second problem was the car died twice. Both times it happened I just lost power. No regenerative braking, just coasting to a stop. Both times I toggled the key off and on a couple of times and got it running again. Both times it quit when I snapped the throttle to full very quickly. Traction control was off. The car didn't quit on my son Blair. I suspect he is smoother on the throttle and fed the power on more gradually. In my last run I concentrated on feeding the power less abruptly and had no troubles. Anyone, ideas on the power failure's? Any suggestions on brake pads?
