Three NASCAR Monster Energy Cup Series drivers spent two days testing, getting a taste of the new rules package this past week at the 2-mile Auto Club Speedway in Fontana, CA.

Martin Truex Jr. marked his first on-track action in the Joe Gibbs Racing No. 19 Toyota, and his predecessor — Daniel Suarez — took his first turn at the wheel of the Stewart-Haas Racing No. 41 Ford. The two were joined at the 2-mile track by 2018 Monster Energy NASCAR Cup Series champion Joey Logano in the Team Penske No. 22 Ford.

It was the first time for the drivers with changes that included air ducts, a larger rear spoiler and other aerodynamic changes, including a tapered spacer intended to reduce horsepower to a target number of 550.

“To continue to do a great job that this team did last year," is how Suarez answered a question on how he expects to do at SHR. “Wednesday was a very productive day for us, it will bring information to the table for Stewart-Haas racing and my teammates as well.

“Everything was good in the shop, in the race car and then you come to the race track and you have to change things here and things there."

Suarez’s transition to the No. 41 driver’s seat was two days (on his 27th birthday) after announcing he had joined SHR

“So far, everyone at Stewart-Haas Racing has made me feel like home," Suarez said during a Monday press conference. “I feel like a lot of good things are happening so we can perform well on and off of the race track."
