Oliver Jarvis paced Saturday’s afternoon practice session at WeatherTech Raceway Laguna Seca, which was marred by an on-track incident between the No. 31 Action Express Racing Cadillac DPi-V.R and No. 7 Team Penske Acura ARX-05.
Jarvis reeled off a 1:15.877 lap time in the No. 77 Mazda RT24-P late in the session to edge out the No. 6 Penske Acura DPi of Dane Cameron by 0.185 seconds.
The sister No. 55 Mazda DPi was third on the time charts, although the story of the session came between two of the DPi championship rivals.
The No. 31 Whelen-sponsored Cadillac of Felipe Nasr was hit by the Helio Castroneves-driven Acura early in the session, resulting in damage to both cars.
Castroneves was given a stop-and-hold plus 60-second penalty for unsportsmanlike conduct while Nasr was handed a stop-and-go for a pit exit violation.
While the No. 7 Acura briefly returned to the track, it was later taken behind the wall for further repairs, while the Action Express entry was fully repaired in the pits.
The incident came two weeks after the two cars — in the hands of teammates Ricky Taylor and Pipo Derani — made contact in the closing stages of the Motul Petit Le Mans, leading to controversy post-race.
The second and final WeatherTech Championship practice session of the day also saw a crash by the No. 85 JDC-Miller Motorsports Cadillac of Matheus Leist, who had a suspected mechanical issue in Turn 2.
Corvette Racing’s Jordan Taylor paced the GT Le Mans class in the No. 3 Chevrolet Corvette C8.R, while Bill Auberlen remained quickest in GT Daytona with his No. 96 Turner Motorsport BMW M6 GT3.
The No. 52 PR1/Mathiasen Motorsports Oreca 07 Gibson — the only LMP2 entry this weekend — elected to miss the session in order to make changes to the car ahead of qualifying, which is set for a 8:30 a.m. PT start on Sunday morning.
