Teams testing at New Smyrna: two Nextel Cup teams testing ay New Smyrna Speedway in Florida. Joe Gibbs Racing arrived at the half-mile track Tuesday with two haulers, three [COT] Nextel Cup Chevy, three drivers (including Tony Stewart) and more than a dozen mechanics. Bill Davis Racing was represented by its #36 Toyota, with Jeremy Mayfield at the wheel, and the #5 Tundra truck raced by Mike Skinner. All the stock cars were of the Car of Tomorrow variety. It's the first time in recent memory that NASCAR Cup teams have tested at New Smyrna, which is sanctioned by FASCAR. The two sanctioning bodies have no connection. Skinner's team had booked the track and the others piggy-backed their way into the facility. Today's session is closed to the public. Aric Almirola was behind the wheel of the #18, normally driven by J.J. Yeley. Mike McLaughlin was assisting Stewart with a pair of #20 Chevys. Gibbs Racing was going to test at a short track in Georgia, but decided to try New Smyrna at the last minute. Joining in the test session was Jamie Skinner, Mike's son, who was driving a FASCAR Late Model. At one point during the afternoon a truck, Cup car and Late Model were on the course at the same time. Mayfield has struggled this season in his new Toyota ride. Without owner's points from last season, he has failed to make six grids through nine Cup events. He hopes this test session helps him conquer the next Cup race, scheduled Saturday night at Richmond International Raceway. "This is the first time I've been around here in a racecar," Mayfield said. "It's a neat little track. I think we've picked up some information." Gibbs Racing plans to return here for more testing in the fall.(Daytona Beach News Journal)(5-2-2007)
