It's been like that for a while now...
"It's about power to weight, or rather downforce to weight. That's why a NASCAR car can't go around the track flat because it weighs 3,500 pounds and makes maybe 1,200 pounds of downforce. Same thing with a sprint car which weighs 1,800 pounds and makes only two hundred pounds of downforce. An Indy car weighs 2,000 pounds with fuel and driver, and it makes 2,000 pounds of downforce. So you've got to change the rules so it doesn't have anywhere near the downforce it's got now.
