LeMans Hour 4: Porsche leads two Audis
 |
| The No. 17 Porsche back in front |
Brendon Hartley was in the lead of the Le Mans 24 Hours for Porsche by 15 seconds over the #9 Audi in a fourth hour run mostly behind the safety car.
KCMG's Oreca still leads LMP2, with Nicolas Lapierre at the wheel.
With its fourth stop completed and racing underway again, KCMG's lead was 40s – its buffer before TDS's pre-safety car stop – and Lapierre ended the hour with 33s up his sleeve.
Corvette led a tight GTE race. Tommy Milner led in the #74 Chevrolet entry.
In GTE Am the #72 SMP Ferrari leads again, having got ahead of the #98 Aston Martin in a battle that has raged almost from the very start.
