While FIA World Endurance Championship teams are at Silverstone unloading for this weekend’s season-opener, Audi has continued its testing program in preparation for the 24 Hours of Le Mans.

The German manufacturer is testing an updated version of its R18 today at Monza, in what appears to be low-downforce Le Mans aero.

Details of the test have not yet been revealed but judging by the photos, the nose of the diesel-powered LMP1 hybrid is noticeably different than the high-downforce trim the R18 ran in last month’s official Prologue pre-season test at Paul Ricard.

Audi is expected to outfit its two R18s in high-downforce aero for Sunday’s Six Hours of Silverstone, which marks the kick-off of the nine-round global championship.
