http://www.autoextremist.com/fumes1/The article states a major push in motorsports coming from GM in the near future...along with a twin turbo V6 to compete at Indy.
About time some American Iron got back in the game.
I've also been reading about how the Indy execs are thinking about making the series have more public appeal. They are experimenting with new designs for future cars. One is called the Delta Wing, shown in this link...
