Kyle Busch paced the field on the final day of testing at Daytona International Speedway Thursday.

DAYTONA BEACH, Fla. — It didn't take Kyle Busch long to settle into his new ride with Joe Gibbs Racing — just three days, in fact.

Busch paced the field on the final day of testing at Daytona International Speedway, and his lap of 188.830 mph was fastest of all 26 cars that participated in the three-day session.

The showing was a relief to the talented 22-year-old, who despite two appearances in the Chase for the championship, lost his seat at elite Hendrick Motorsports when the team signed Dale Earnhardt Jr.

"It's been a big deal to be able to come out here and run strong," Busch said after Wednesday's final session. "It's easy. Everything's going great."

Few would have blamed Busch if he'd been nervous about the test session, which also came in a new car. Signed as an 18-year-old at Hendrick, he grew up in that organization and found all of his success driving a Chevrolet.

When he signed with JGR, that team also fielded Chevys. But the team later switched to Toyota, and heads into this year expected to help the automaker find success in NASCAR.
