A pair of much-anticipated debuts will occur this weekend in the Busch Series' Circuit City 250 presented by Funai at Richmond International Raceway.

Third-generation racer Bobby Santos III of Franklin, Mass., a Bill Davis Racing development driver, will attempt his inaugural Busch start in a No. 91 Toyota fielded under the auspices of Riley-D'Hondt Motorsports.

This weekend's entry, sponsored by team co-owners Bill and Bob Riley's engineering company, Riley Technologies, is a unique collaboration between notable entities from sports-car and stock-car racing.

The car comes from Davis' shops and will be crewed by a combination of BDR and RDM employees, overseen by veteran crew chief Gene Nead, who went to work at Davis' operation at the end of 2006.

Davis, who fields pairs of full-time Toyota teams in both the Nextel Cup and Craftsman Truck Series, wanted to broaden Santos' stock-car portfolio without stretching BDR's resources too thin.

Since announcing in August 2006 they'd enter NASCAR's national tours the Rileys, who have a long legacy of sports-car championships and team co-owner Eddie D'Hondt, a former Northeast Modified stock-car driver who more recently has worked in Cup team management and as a Cup spotter, wanted to advance their plans.

"It took a lot to make it occur," D'Hondt said. "We've been working on quite a bit of stuff behind the scenes and it was a long time for it to come to fruition.

"BDR had new drivers on both the Cup and Truck sides of their program and with all the Car of Tomorrow development they have to do, there would have been an overabundance of priorities if you added in trying to raise a young guy [Santos].

"What we felt we could bring to the table was the ability to tutor Bobby along, work with him and develop him and, we hope, run him full-time next year."

Santos, 21, has made an auspicious debut in three ARCA starts this season, winning the Pork Pole Award for his debut at USA International Speedway in Lakeland, Fla., and qualifying on the outside of the front row in his first trip to Kansas Speedway, last weekend.

Santos, who made a mark in a variety of open-wheel divisions including Midgets, Sprint Cars and Supermodifieds, led the most laps in Lakeland, a .750-mile short track that's similar to Richmond and also led at Kansas before his car's engine failed.

"He's very talented," D'Hondt said of Santos. "He's a young man who, when we tested at Richmond last month was quickest, and he had never been in a Busch car before."

After getting on the track for the first time this weekend after eight months of negotiating with sponsors and other factions, D'Hondt said Riley-D'Hondt's future will be exposed in a rush.

"We're planning to make a fairly significant announcement during Charlotte Speedweeks, where we're planning to have two Toyota Camrys on track," D'Hondt said. "Part of that announcement will be that we'll run a package of races with Bobby and David Green."

The team has registered Busch car numbers 91 and 92 with NASCAR Competition for this season.

D'Hondt cited Joe Gibbs Racing's highly regarded driver development program, which has harvested Tony Stewart, Denny Hamlin, J.J. Yeley and Aric Almirola; along with having 16-year-old Joey Logano, who's won the first two NASCAR Grand National Division events this season and Marc Davis, as their model for working with Santos.

"It remains to be seen how he develops," D'Hondt said. "But from a driver's standpoint, the key to bringing along young people is putting them in good equipment and surrounding them with good people -- then [the result is] you get people like Denny Hamlin.

"The Gibbs people have done a good job with that and that's what Bill Davis and [BDR competition director] Tommy Baldwin's goal is with Bobby. They have a very talented young man and with David Green working on coaching him, we're going to do all we can to raise him and we'll see how he develops."
