Update: Richard Petty Motorsports teammates Ambrose and Aric Almirola completed a successful two-day test session at Sonoma Raceway on Wednesday, Sonoma Raceway PR reports.
Recommendation: Ambrose and his teammate are the first drivers to turn hot laps on the California road course in the new Gen-6 car. The Australian turned 75 laps on the winding road course and put his No. 9 Ford through the paces. Ambrose is an expert driver on these circuits, so the extra track time could help him into victory lane at Sonoma later this summer.
