Detroit Grand Prix looks to build upon successes, hoping to host another IndyCar doubleheader

The Detroit Grand Prix hosted two full-length races in a weekend for the first time in IndyCar history. At least one person wants to make open-wheel racing doubleheaders an annual tradition in the Motor City.

Detroit Grand Prix chairman Bud Denker says he hopes IndyCar gives him the green light to market another two-race event in 2014.

Compared with last year, more fans went to Belle Isle and the television audience was larger.

Simon Pagenaud won Sunday's race and Mike Conway finished first Saturday on an improved track that held up much better than it did the year before when pot holes and grooves spoiled the show.
