Porsche has enjoyed a dominant start to the first WEC season run to the winter calendar, with both of its new-generation 911 RSR-19s scoring a win apiece.
That has allowed the Weissach-based marque to build a 22-point lead in the manufacturers’ standings, while its two crews occupy the top of the drivers' table.
While refusing to concede defeat in the title fight just yet, Thiim says Aston Martin must win the bonus-points race in Bahrain to prevent Porsche from running away with the championship.

“Fuji we got unlucky with full course yellow, cost us a podium. Honestly on track we won in China, but unfortunately we got disqualified.
“In terms of result and pace, we are at the front. We would be winning by a long way now if this wasn’t the case. However it’s not.
“Just going to try to make the most of damage that we’ve done and just try and work forward. It’s not over yet but it’s going to be difficult.”
