What is Nissan's history in the top class at Le Mans? Do they have any as an official entrant?
1986-1990 in Group C1, first with V6 turbo-powered Marches, then with the R89C and R90CK Lola-built cars with 3.5 liter turbo V8 engines. R90CK most famous for Mark Blundell's stonker pole lap in 1990, wastegate jamming shut on the out-lap and overboosting the engine to over 1000bhp, but everything held together in order for that car to outqualify the whole field by 7 seconds. Best result in that era though - only a 5th place in 1990.
1997-1998 - the R390 in GT1; in '97 their effort fell apart due to a bad batch of oil coolers that kept disintegrating, in '98 they were steady and reliable but not quick enough.
1999 - R391 LMP, one car written off in Le Mans qualifying, one DNF with mechanical issues.
EDIT: And the Blundell-Bailey-Brancatelli R90CK that sat on pole in 1990 sits proudly at the forefront of the image in the OP.
