The Peugeots continue to lead overall at Sebring with the No. 08 turbo diesel 908 HDi FAP ahead of its sister No. 07. Nicolas Minassian and Anthony Davidson are the respective drivers. Davidson had a minor spin at turn 7, but continued without damage.

Additionally, the two are in the same order in the MICHELIN® GREEN X® CHALLENGE standings through three hours. Based on the level of fuel consumption, speed, and efficiency, the 08’s Green Racing Challenge (GRC) score is 1.927, to the 07’s 2.071. Both cars run on Shell GTL diesel.

The Drayson Racing Lola B09/60 Judd is the first car listed on E85, ahead of three prototypes on E10. The Dyson Racing Lola B09/86 Mazda is making its first official start on the newly approved isobutanol blend, but has been in the garage to replace its oil pump and sensors, according to the team.

In GT, the No. 44 Flying Lizard Motorsports Porsche leads with a GRC score of 2.473, just ahead of the two Corvettes and the sister Lizard Porsche. All four run on E85 and are cumulatively separated by a .113 of a point.

Five hours remain in this year’s 12 Hours of Sebring. Following a stint of more than four hours of green flag running, the second full course yellow flew at 4:45 p.m. local time when J.R. Hildebrand spun in-between turns 15 and 16. He lost the rear of his Genoa Racing Oreca FLM09 in the LMPC class, and spun into the barriers.

The majority of the field visited the pits for the latest round of stops, but the Peugeots split their strategies. The lead No. 08 908 HDi FAP did not stop under the yellow while the No. 07 did. The 08 still leads overall by 38.4 seconds with five hours, 15 minutes remaining.

Michelin cars still run in the top 9 positions overall as the leaders have completed more than 200 laps. The HPD ARX 01-c still leads in P2, while Risi Ferrari F430 GT and Level 5 Motorsports lead in GT2 and LMPC respectively.

The manufacturer battle in GT2 has intensified. After the restart, Joerg Bergmeister in the Flying Lizard Porsche 911 GT3 RSR made a move on Gianmaria Bruni in the Ferrari. But on the same lap, Bruni retook the point from Bergmeister and resume in the position he’s been all day. The No. 92 BMW M3 threatened for a bit, but has since fallen a lap behind and is now third in class.

The MICHELIN® GREEN X® CHALLENGE standings have also been updated. In simplest terms, a competitor’s Green Racing Challenge score measures who can go the fastest and farthest with the smallest environmental footprint.

Through six hours, both Peugeot and Porsche are in positions one and two. Peugeot’s diesels have GRC scores of 2.147 and 2.317, more than half a point ahead of the Drayson Racing Lola Judd. In GT, both of the E85-fueled Lizard Porsches are close, with scores of 2.681 and 2.700.
