There’s no doubt racing fans noticed the difference when the Indy Racing League switched from pure methanol to a 98 percent blend of ethanol as the fuel of choice. The smell of burning ethanol is just as distinct as the roar of Indycars racing around the track.

Love the races? Love the fuel? Love the smell? Tell others about your obsession with an authentic IndyCard. An Indy photog sent me this all too appropriate IndyCard as we close in on launching another season of Indy Racing.

Don’t miss the Homestead season opener on March 29 at Miami Speedway. Even if you can’t make it to the track to “breathe ethanol,” you can catch the race at 8 p.m. on ESPN2.
