As of a western swing through Fontana, Calif. and Las Vegas, Nev. wasn't enough, the NASCAR Sprint Cup Series got its fourth official test session wrapped up in Phoenix on Tuesday afternoon.The test at Phoenix International Raceway was the fourth of six that teams suggested to NASCAR prior to the season, and joins Daytona, California, and Vegas as tracks the teams have tested at.
Only Pocono and Lowe's Motor Speedway remain on the official Sprint Cup series testing docket. Teams can otherwise only test on tracks that the Sprint Cup series doesn't compete on.
Juan Pablo Montoya -- who was fastest during the Las Vegas test prior to the season -- again led all drivers over the five different sessions offered. The No. 42 put down a lap of 131.459mph in the Tuesday morning test session.
