In the competition debut of the Acura ARX-05 at WeatherTech Raceway Laguna Seca, Team Penske reached the top of the combined timesheet on day one of the weekend with its pair of prototypes.

Dane Cameron, driving the No. 6 Acura DPi, executed a 1:16.865 time on the car’s 31st and final lap of the one-hour session. The sister No. 6 Acura turned two fewer laps and took 0.115 more seconds to lap the circuit on its best revolution but placed second.

After Renger van der Zande set the Cadillac DPi-V.R he shares with Jordan Taylor well apart from their competition in Friday’s first session, Cameron improved upon the Dutch driver’s time by 0.017 seconds.

The Acura duo is followed on the Practice 2 results by Filipe Albuquerque, the fastest driver of a Cadillac DPi in the session. Castroneves’ lap in the No. 7 Acura put the Penske-run cars 0.268 seconds clear of Albuquerque in the No. 5 Action Express Racing Cadillac.

CORE autosport star Colin Braun owned the fastest lap for much of the session but fell to fourth on the timesheet as the top three DPi cars turned their final laps. At 1:17.284, Braun improved upon his Practice 1 pace by nearly 1.3 seconds and advanced three positions in the 13-car Prototype field.

The car that topped the first practice completed the top five in Practice 2 with Wayne Taylor’s son Jordan lapping within two-thousandths of a second of Braun.

Strong showings from both Nissan Onroak DPis to begin the weekend were followed by laps good enough for seventh and 10th in this second session. Mazda Team Joest, meanwhile, placed sixth and ninth.

Ford Sweeps GTLM on Practice Day

The top two spots in GT Le Mans were filled by Chip Ganassi Racing’s Ford GT duo during both of Friday’s hourlong practice outings.

After Richard Westbrook took the No. 67 Ford to the top in Practice 1, Dirk Mueller prevailed in Practice 2 to make the No. 66 fastest. Westbrook’s co-driver Ryan Briscoe placed second with a lap 0.162 seconds slower than the best effort from Mueller.

A gap of more than half a second between the Fords and their competition was reduced to 0.178 seconds in the afternoon outing as Jan Magnussen and the No. 3 Corvette C7.R were that far back from the second-placed Ford in Practice 2.

Tommy Milner in the second Corvette Racing entry and John Edwards, the fastest BMW Team RLL driver of the day, completed the top five.

Park Place Reaches Top in GTD

Joerg Bergmeister made Park Place Motorsports the fastest GT Daytona team Friday at Laguna Seca with the fastest lap in the afternoon.

At 1:25.148, Bergmeister’s time in the No. 73 Porsche 911 GT3 R created a gap of 0.123 seconds between he and Alvaro Parente in Meyer Shank Racing’s No. 86 Acura NSX GT3.

No manufacturer appeared twice in the top five, which was rounded out by Mercedes-AMG, Ferrari and Audi machinery. The Lamborghini Huracan GT3 of Paul Miller Racing was notably absent from this lead group as it ended the session eighth.

A final 60-minute practice will run from 8:30–9:30 a.m. PDT Saturday before qualifying begins at 12:45 p.m.
