No. 6 Porsche leads Sahlen's Six Hours at halfway

An eventful first half of the Sahlen’s Six Hours of The Glen run under a variety of weather conditions saw the No. 6 Porsche Penske Motorsport Porsche 963 driven by Matt Campbell at the head of the field at the halfway point. Streaming race coverage continues in the U.S. on Peacock and internationally via the IMSA YouTube channel through the checkered flag just past 6pm ET.

The IMSA WeatherTech SportsCar Championship commenced the third round of the 2025 IMSA Michelin Endurance Cup season and the sixth race weekend of the full season at Watkins Glen International first under cloudy skies, before a deluge of rain a half hour into the race upended the proceedings and six full-course cautions disrupted the flow.

From GTP and overall pole, Renger van der Zande led the 55-car field to green in the No. 93 Acura Meyer Shank Racing w/Curb-Agajanian Acura ARX-06 but he wasn’t up front for long. From 10th on the grid, Felipe Nasr delivered a remarkable start to the lead by lap 4 in the No. 7 Porsche Penske Motorsport Porsche 963, completing the lead with a two-in-one on the outside of Turn 9 past Jack Aitken in the No. 31 Cadillac Whelen Cadillac V-Series.R and van der Zande, who’d fallen to second.

Nasr wasn’t the only big mover. From last on the 20-car GTD grid, Alessandro Pier Guidi leapt to fourth in the same timeframe in the No. 21 Af Corse Ferrari 296 GT3.

When the skies opened a half hour into the race, several incidents followed, including a significant collision between the No. 52 PR1 Mathiasen Motorsports and No. 11 TDS Racing ORECA LMP2 07 cars in LMP2 exiting Turn 9. As a GT car tipped the No. 52 car into a spin, the No. 11 car had nowhere to go and hit the No. 52 car square on. The incident popped the No. 11 car’s windshield out of the car. Both drivers, Rodrigo Sales and Steven Thomas, were evaluated and released from the infield care center.

The rain’s effect on the race necessitated most of the field switching from Michelin’s slick tires to wet-weather tires during the deluge, and back to slicks again as the humid conditions helped the track dry quite quickly.

In the third hour, most teams had completed their first driver change of the race – this race allows for teams to run either two or three drivers, depending on class – and shuffled the leaders.

By pitting in advance of a yellow flag for the GTD PRO Motul Pole Award-winning No. 9 Pfaff Motorsports Lamborghini Huracán GT3 EVO2 stopped on course, Lamborghini’s GTP entry moved to the front of the field.

Romain Grosjean moved clear to the lead in the No. 63 Automobili Lamborghini Squadra Corse Lamborghini SC63 and led away from Kaku Ohta who’d taken over the No. 93 Acura from van der Zande. Daniil Kvyat (No. 63 Lamborghini) and Nick Yelloly (No. 93 Acura) just took over right at the three-hour marks under the sixth and most recent full-course caution.

With the caution, the orders changed and the unofficial leaders listed at the three-hour mark included:

• GTP: No. 6 Porsche Penske Motorsport Porsche 963
• LMP2: No. 43 Inter Europol Competition ORECA LMP2 07
• GTD PRO: No. 1 Paul Miller Racing BMW M4 GT3 EVO
• GTD: No. 21 Af Corse Ferrari 296 GT3

The top three scorers at the three-hour mark receive five, four and three points, respectively, per class for the Michelin Endurance Cup with all others receiving two.

The No. 7 Porsche Penske Motorsport Porsche 963 shared by Felipe Nasr and Nick Tandy continues to lead the Michelin Endurance Cup standings in the GTP class, with the No. 43 Inter Europol entry atop LMP2, the No. 1 Paul Miller Racing BMW leads GTD PRO points, and the No. 21 Af Corse Ferrari moved into the GTD Michelin Endurance Cup lead.
