Le Mans returnee Martin Brundle reckons the LMP2 class in this year's 24-hour race rivals the halcyon days of Group C for competitiveness.
Brundle won Le Mans with Jaguar in 1990, and is returning to the event for the first time since 2001 to share Greaves Motorsport's LMP2 Zytek-Nissan with son Alex and Lucas Ordonez.
After participating in the Le Mans test day last weekend, Brundle told AUTOSPORT that he had been taken aback by the quality of the entry in the class.
"The first day confirmed how competitive LMP2 will be," he said. "We are fine on pace, but there are a lot of good drivers in a lot of a good cars.
"P2 has changed out of sight. It will be harder to finish in the top three in the class than I perhaps first thought. It is seriously competitive.
"It kind of reminds me of Group C in the late 1980s. I look down the entry list and see more direct competitors than I did when I was driving with Jaguar."
Brundle's car was eighth quickest on Sunday, two seconds down on the pacesetting OAK Morgan - although Brundle said he had been "a bit over-cautious" during the test.
