Rockenfeller puts Audi top in practice

Audi waited until the final half hour of first practice for the Le Mans 24 Hours to show its hand as 2010 winner Mike Rockenfeller topped the timesheets with a lap of 3m27.986s

Rockenfeller puts Audi top in practice

The four-hour session ended with a flurry as Audi and Peugeot traded fastest times.

Andre Lotterer was first to break through Peugeot's dominance with a 3m28.296s lap and even qualifying king Sebastien Bourdais could not quite match it with a final fresh-tyre run in the closing minutes. Then Rockenfeller chipped in to displace his team-mate with just a minute and a half to go.

Bourdais was the fastest Peugeot driver on 3m28.536s, third overall and less than 0.1s quicker than team-mate Alex Wurz in the #7 car.

The recent change in ballast regulations had a marked effect as the year-old ORECA-run Peugeot 908 HDi, which has been allowed to run 15kg less ballast, topped the timesheets for much of the session's opening two hours. The car, shared by Olivier Panis, Nicolas Lapierre and Loic Duval, posted a 3m30.096s lap that was not bettered until Simon Pagenaud sliced under the 3m30s barrier in his factory Peugeot 20 minutes shy of the halfway mark.

By the end, though, the pace of the factory entries told and the ORECA car finished the session seventh quickest, having not improved on its earlier time.

The session was red-flagged after an hour when Raymond Narac's #76 IMSA Performance Porsche 911 crashed heavily in the first section of the Porsche Curves. The car dislodged the end of the tyre wall and came to rest on the edge of the gravel trap, bringing about an 18-minute delay.

Lola chassis initially had the advantage among the petrol-powered LMP1 entries. The two Toyota-engined Rebellion coupes were quickest for much of the session, challenged mainly by the #15 and #16 Pescarolo-Judds. Their next quickest rival, the #20 Zytek, was 5s adrift. At the end of the session Julien Jousse set 3m34.271s in the #16 works Pescarolo, undercutting the #13 Rebellion Lola's best time, set by Jean-Christophe Bouillion, by just a second.

Aston Martin's brace of AMR-Ones encountered mixed fortunes. Darren Turner reported that adjustments to the #007 car he shares with Christian Klien and Stefan Mucke improved its stability, closing the session with a quickest time of 3m46.299s. The #009 car covered just 11 laps before pitting for an extended stay in the garage while an oil leak was traced.

In spite of carrying additional ballast, Strakka Racing topped the LMP2 entries with its HPD ARX.01. Danny Watts, Jonny Kane and Nick Leventis set a quickest time of 3m42.863s, edging out the #48 ORECA Nissan shared by Alexandre Premat, David Hallyday and Dominick Kraihamer. A brake fire hindered the other pre-race favourite, the Mike Newton/Tommy Erdos/Ben Collins RML HPD ARX.01.

BMW set the pace in the GTE Pro class. Jorg Muller was first to break the four-minute barrier with a 3m59.028s in the #55 M3 GT he shares with Augusto Farfus and Dirk Werner, followed quickly by Andy Priaulx with a 3m59.763s in the #56 car.

There was a minor scare for Corvette Racing when the Oliver Gavin/Jan Magnussen/Richard Westbrook car started smoking on its out-lap after the restart. The problem was traced to a dislodged power steering hose and the car went back out to record the third fastest time in the session, 4m00.467s.

The new Lotus Evoras propped up the GTE Pro class, the fastest time of 4m09.576 coming at the hands of Johnny Mowlem. The Jetalliance team is pinning its hopes on an economy run. "We're going to try to squeeze 15 laps out of a tank and get triple stints out of the Michelin tyres," said Mowlem. "We've got three consistent drivers so we're hoping for a good result."

The #71 AF Corse Ferrari shared by NASCAR racer Michael Waltrip, Robert Kauffman and Rui Aguas suffered a left rear puncture while Kauffman was at the wheel and limped back to the pits during the stoppage.

Fabien Giroix, Michael Wainwright and Roald Goethe dominated GTE Am in their Gulf AMR Aston Martin, setting a quickest time of 4m04.702s, comfortably quicker than the 4m06.266s posted by Darren Law in the #81 Flying Lizard Porsche 911.

Roger Wills had a gyration at the exit of Porsche Curves in the #62 CRS Racing Ferrari just before the half-way point of the session and hit the wall, damaging the car.

The 1-2 finish achieved by Toyota at this year's Le Mans 24 Hours was a result that will have surprised few, given its status as pre-event favourite.

It's 50 years since Jo Siffert was killed in his prime at Brands Hatch. The Swiss scored just two world championship wins in a Formula 1 career spent largely with privateer teams, but showed on numerous occasions in single-seaters and in sportscars with Porsche that he could beat any of the best drivers of his era given the right equipment

OPINION: With four of the five Hypercar entries unproven in a 24-hour race, it would not have been unexpected for at least one of them to suffer serious reliability trouble. That they all managed to make it through the race relatively unscathed, says GARY WATKINS, was something of a surprise.
