The Leaf is the perfect Autocross car!

Most of the weight is right at the floor of the car. The batteries and the motor just a little higher than the middle of the wheels. All the torque is available from 0 rpm. This is important in autocross. It's a hatchback, so it's practical. You could haul 4 track tires in the trunk with the rear seats up (the size of the stock tires). Different tires would be a must though, because the stock tires offer little in terms of handling. Just be sure there is a super charger nearby.
