NASCAR 1st Multicar Test With '13 Cars, New Aero
The two-day test at Texas started Tuesday, with 100 pounds removed off the right side and 60 pounds off the left side of the cars. It is also part of a test with Goodyear tires built specifically for the new cars to optimize grip.
Robin Pemberton, NASCAR vice president of competition, says the cars were built to get more mechanical grip and reduce the aero dependency.
Juan Pablo Montoya was "happily surprised" with the reduced downforce. He says the car slid around a little bit, but wasn't unpredictable and didn't do anything strange.
The new Cup cars for Chevrolet, Ford and Toyota look more like their passenger car counterparts.
