Juan Barnett's post of a rendering of a race-spec Tesla Model S got me thinking; can the Model S be realistically adapted for production-based touring car racing? How much must the car be altered to meet regulations? How will the electric motor's performance be matched with competing internal-combustion engines? Can the battery pack be made as safe as a fuel cell? And, the biggest question; is it realistic to race a car with a energy-replenishment time measured in minutes, not seconds?
