NASCAR RACES THIS WEEK AT THE ROAD COURSE AT SONOMA, KNOWN FOR ITS COMPLICATED TWISTS AND TURNS, AND IT'S A TRACK RYAN NEWMAN LOVES...

"I LOOK FORWARD TO GOING OUT THERE. I LOVE THE CHALLENGE. I LOVE THE ROAD COURSE. TO ME THERE ARE TWO  GOOD PASSING ZONES  AND ELEVEN CORNERS."

FOR MARCOS AMBROSE, WHO GREW UP RACING ON ROAD COURSES IN AUSTRALIA, SONOMA TESTS DRIVERS IN TWO WAYS...

"PHYSICALLY IT'S OBVIOUSLY QUITE CHALLENGING WITH THE HEAT AND THE AMOUNT OF WORK YOU HAVE TO DO, BUT I THINK MENTALLY IS THE TOUGHEST PART."

NASCAR FINES JOE GIBBS RACING'S THREE CREW CHIEFS $50,000 EACH FOR BRINGING UNAPPROVED OIL PANS TO LAST WEEK'S RACE AT MICHIGAN, AND PUTS THEM ON PROBATION THROUGH THE END OF THE YEAR.

AND RED BULL RACING'S GENERAL MANAGER  SAYS HE'S HOPEFUL HE CAN FIND INVESTORS TO KEEP GOING AFTER 2011 WHEN THEY LEAVE NASCAR.  THE ENERGY DRINK COMPANY IS BOTH OWNER AND SPONSOR --FIELDING TEAMS FOR KASEY KAHNE AND BRIAN VICKERS.
