Austin WEC: Porsche leads first practice with Dumas and Webber

Romain Dumas beat Porsche team-mate Mark Webber to the top of the timesheets in opening free practice for this weekend's Austin round of the World Endurance Championship

Austin WEC: Porsche leads first practice with Dumas and Webber

Dumas jumped ahead of Webber by just under a tenth of a second with 15 minutes to go with a 1m47.425s and then bettered it with a 1m47.231s aboard the #18 Porsche 919 Hybrid.

That left him nearly three tenths up on Webber's best of 1m47.514s.

Oliver Jarvis set the best Audi time to take third spot with a 1m49.027s, almost 1.8s off the pace.

The second Audi R18 e-tron quattro completed only four laps before undergoing an alternator change and ended up seventh in the times on a 1m53.471s recorded by Andre Lotterer.

Toyota took fourth and fifth spots with its pair of TS040 HYBRIDS, Sebastien Buemi's 1m51.279s putting him nine tenths clear of team-mate Mike Conway.

The KCMG squad led the way in LMP2 with a 1m57.764s lap from Nicolas Lapierre at the wheel of its ORECA-Nissan 05.

That put him seven tenths up on the 1m58.342s set by Johannes van Overbeek in the best of the Extreme Speed Motorsports Ligier-Honda JSP2s.

He was in turn just one hundredth up on the sister car in the hands of Ryan Dalziel.

James Calado set the pace in GTE Pro aboard his AF Corse Ferrari 458 Italia.

His 2m06.753s was six tenths up on Toni Vilander's best in the sister car, which stopped out on the circuit early in the session with an electronic problem.

AF was trying the same engine ECU that had failed early in the race at the Nurburgring last month to try to fully understand the problem.

Patrick Pilet was only five thousandths behind the second Ferrari in the fastest of the two Manthey Porsche 911 RSRs.

Patrick Long was fastest for the Proton Porsche team in the GTE Am class.

The standout memories of Le Mans 2021

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.

Toyota scored its fourth Le Mans 24 Hours victory and a 1-2, with the #7 car of Kamui Kobayashi, Mike Conway and Jose Maria Lopez beating the #8. But although it looked straightforward from the outside, Toyota faced serious problem that had to be solved with some quick-thinking and ingenuity

How overlooked Mazda produced one of Le Mans' greatest shocks

The screaming rotary-engined Mazda 787 is regarded as one of the most popular Le Mans 24 Hours-winning cars, but until its surprise success on this day 30 years ago it was never regarded as a likely victor. But that reckoned without a new technical partner, some canny political manoeuvring and a rival's bizarre self-inflicted weakness

Many were quick to dismiss Glickenhaus when the boutique American sportscar firm's entry into the top class of the Le Mans 24 Hours was announced. It's all-new LMH racer, powered by an engine built by a rally specialist, goes in as the underdog against Toyota but the mathematical odds suggest that it has more than just a faint hope of success

Having twice missed out on Formula 1 and reinvented himself as a touring car driver, Jose Maria Lopez has had a rocky ride to becoming a four-time world champion. One more would put him level with his nation's favourite son, but there's another prize he would value far more than the honour of matching Juan Manuel Fangio's tally
