Austin WEC: Audi and Toyota top a practice session each on Thursday

Mike Conway, Kamui Kobayashi and Jose Maria Lopez scored a second successive World Endurance Championship title in the #7 Toyota, as its new Le Mans Hypercar went unbeaten. Autosport recaps how each of the four classes in the 2021 season were won and picks out the best LMH and GTE drivers

OPINION: The deeply unsatisfying ending to a brilliant World Endurance Championship GTE Pro battle in Bahrain had Ferrari provisionally heading back from the desert as the victor. But Porsche plans to appeal the outcome, which rests on a number of confusing elements that have yet to be satisfactorily explained

The Ferrari versus Porsche fight for the World Endurance Championship's GTE Pro title had been a finely-poised affair, right up until Alessandro Pier Guidi's punt on Michael Christensen in the closing stages of the Bahrain 8 Hours handed Ferrari a provisional title, pending Porsche's appeal. Here's how the controversy played out

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. But the result was anything but straightforward, as worsening fuel pressure concerns required the team's drivers and engineers to pursue "creative fixes" on the fly. Here is the full story of how it reached the end without a lengthy pit visit

In the penultimate round of the 2021 World Endurance Championship, a better run of tyre wear for Mike Conway, Jose Maria Lopez and Kamui Kobayashi brought the Toyota trio its third win from five events, as the #7 squad put one hand on the title. Here's how the first of the WEC's two Bahrain enduros played out

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

Team WRT has been at the forefront of GT racing for years and made a successful move to prototypes for 2021, capped by an LMP2 win on its Le Mans debut. It could've been even better had the race been one lap shorter, when its cars ran 1-2, but the stranger-than-fiction reality has spurred the team to reach greater heights

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.
