Top NASCAR Drivers Use Memphis as Proving Ground for Car of Tomorrow

The Memphis Motorsports Park was a very busy place Tuesday morning.

Some Top name drivers on the NASCAR circuit here to test and tune "the Car of Tomorrow" as the Chase for the Championship winds down.

Just two races left to make the Chase For the Championship and Kurt Bush is pushing hard.

With 2 wins in the last 4 weeks, he's in 12th place now, the cut off line to make the Nextel Cup's 10 race playoff.

Richmond is the final stop and because it most resembles the Memphis track, he's here to test and tune.

"Richmond is the same size track so we want to check some things off our list and if things go well...we only need 30 points to secure the last spot."

If Bush succeeds, he'll hold off Dale Earnhadt Jr. for the last spot.

2007 has not gone well for Dale Jarrett. The former points champion jumped to Toyota in the off season and has found himself at the back of the pack ever since. He's hoping he can find some magic here in Memphis.

Jarrett says:

"It has been a steep learned curve. It's been a lot toughre than Toyota or anyone of the teams have anticipated. Q: Are you close to winning? A: No. I don't think anyone of the teams can say that."

Jarrett was joined by teammates Mark Green and David Reutimann Tuesday.

3 time IRL champion and last years Indy 500 winner Sam Hornish Jr. was also on the scene.

He stopped short of saying he was planning a fulltime move to Nascar.

All of these guys are testing the "car of tomorrow" that will become the mandatory ride next year.

Kurt Bush says it has different aerodynamics that take some getting used to.

"It has a high center of gravity so it has a tendency to want roll more, kinda like an SUV."

The Green flag will drop for real at the Memphis Motorsports Park in late October for the NASCAR Busch Grand National Circuits' Sam's Town 250.
