WEC: Porsche shuffles 911 RSR lineup

Porsche Team Manthey has reshuffled its factory driver lineup in its two Porsche 911 RSR entries for the World Endurance Championshipand at the 24 Hours of Le Mans, following the announcement of the

promotion of Nick Tandy and Earl Bamber to the marque's prototype squad

for Le Mans and the Spa round of the WEC.

From the season-opening round at Silverstone on April 12, Dane Michael Christensen and Richard Lietz of Austria will join forces in the No. 91 911 RSR. Sharing driving duties in the No. 92 will be Frenchmen Frederic Makowiecki and Patrick Pilet, who already teamed up last year to contest the second half of the season. Germany's Wolf Henzler (No. 92) and Jorg Bergmeister (No. 91) will support the pairings as the third driver to contest the 24 hour classic at Le Mans.

In addition to their commitments at the wheel of the 919 Hybrid at Spa-Francorchamps and Le Mans, Bamber and Tandy will continue contesting GT races with the 911 RSR.

"Receiving support from Porsche was the chance of a lifetime as a race driver," Bamber said. "I've reached new levels in every aspect and I'll do my utmost to justify this trust again this season."
