After that pitstop for the No.8, there's about 35s covering the top three.
That's the end of Hour 5. Bourdais and Cadillac lead outright by 19.7s from the No.20 BMW.
Bourdais, of course, is from Le Mans.
This is Sebastien Bourdais' 19th start at the 24 Hours of Le Mans. Still a long way to go, but is there a first Cadillac win at the event coming his way?
The No.38 Cadillac of Bourdais is now in the lead. That's a massive change from the earlier pitstop cycles where the No.20 BMW cycled back into the lead each time.
The No.8 is now in the pits from the lead.
The No.7 Toyota has moved ahead of the No.83 AF Corse Ferrari for 12th down at the first chicane.
Just over 19 hours of racing to go and all 62 cars are still running, albeit a few have encountered some big issues.
The No.62 Corvette is 11 laps down, the No.61 Mercedes is eight laps down, the No.3 LMP2 is nine laps down.
Hirakawa is 38s up the road from Bourdais in the No.38 Cadillac, while the No.20 BMW is back out in third with Robin Frijns behind the wheel.
The No.20 BMW is in the pits now, the No.8 Toyota cycles into the lead.
Doriane Pin continues to lead the way in LMP2 in the No.30 car by just under 20 seconds.
In LMGT3, the No.87 Lexus of Jose Maria Lopez is just 0.2s clear of the lead as pitstops go on.
The No. 12 Cadillac is into the pits, so that releases the No.8 Toyota into second, and eventually the lead when the No.20 BMW stops soon.
The No.38 Cadillac is in the pits, so the No.20 BMW is back in the lead.
What's especially interesting is that, if there is a similar situation close to the end of this race, that Cadillac is rapid in the last sequence of corners. It was the case in qualifying on Thursday, and again last year when it was on pole then.
Such an intriguing lead battle going on here between BMW and Caddy, as well as Toyota on this offset strategy.
The No.38 Cadillac takes the lead again from the No.20 BMW with a daring move into the Ford chicane! What a move!
That gap between Van der Linde in the BMW and Aitken in the Caddy is under half a second now.
The lead battle is hotting up again. The No.20 BMW is just 0.9s clear of the No.38 Cadillac, just like it was at the start of the last hour.
It's easy to forget that this is round three of a world championship. The No.20 leading won last time out at Spa in the FIA WEC.
The No.8 Toyota is in the pits from the lead again, with Hartley stepping out for Ryo Hirakawa.
The No.20 BMW is back into the lead.
Doriane Pin's lead in the LMP2 class is up to almost 28 seconds.
Meanwhile, more trouble for the Iron Lynx Mercedes squad in LMGT3. The No.79 car is being wheeled into the garage. The No.61 had issues earlier in the race.
That Toyota has a heck of a lot of pace in clean air. Now 31.745s in front of the No.20 BMW, albeit on a much lighter fuel load at this point of Hartley's offset strategy.
