Timo Bernhard and Brendon Hartley gave Porsche its first pole of the year, taking their No. 1 Porsche 919 Hybrid to a best two-lap average of 1:55.793 in the 25-minute session.

Their average time was 0.797 seconds quicker than teammates Marc Lieb and Neel Jani, who along with Romain Dumas, inherited the overall win in last month's season-opener.
