He began the 2014 championship qualifying sixth for the season-opening 6 Hours of Silverstone and finishing third. Webber then experienced hybrid technical issues at the following 6 Hours of Spa-Francorchamps leaving he and his co-drivers 23rd overall. At the 24 Hours of Le Mans, Porsche were not preoccupied with victory but Webber's team qualified the No. 20 car second. Webber led on the 22-hour mark but abandoned the car in the garage with a broken anti-roll bar. The next four races saw him finish no lower than sixth; Webber was third at both the 6 Hours of Fuji and the 6 Hours of Bahrain. At the season-ending 6 Hours of São Paulo, his team qualified on pole position, but late in the race, the right-rear of his car was involved in a collision with the No. 90 AF Corse-run 8 Star Motorsports Ferrari 458 Italia of Matteo Cressoni, sending him into a concrete barrier. Webber sustained a contusion of the left lung and a severe concussion but had recovered from the effects of the crash weeks later. He was ninth in the World Endurance Drivers' Championship with 64 points.
