TALLADEGA, Ala. — NASCAR slowed speeds Tuesday on the Car of Tomorrow at Talladega Superspeedway, where only half the field topped 190 mph on the second day of the test session.

With a smaller restrictor-plate, only 27 drivers went over 190. Paul Menard turned the fastest lap of the day at 193.045 mph in a Chevrolet. Speeds reached 196 mph on Monday, and 44 drivers topped 190 mph.

"We have the tools to slow them down. NASCAR did a good job with that," driver Ryan Newman said. "Basically we're just acclimating the car to the racetrack."

The CoT is being phased into competition this season, and it will make its restrictor-plate race debut at Talladega in October.

NASCAR experimented with several restrictor-plate packages and wicker setups, and there didn't seem to be many complaints about the car's handling.
