Hidden on a side road just outside the northern loop of the Nurburgring is the Jaguar test center in the Industrial Park, the Area 51 of cars. JF Musial gets a tour of the test facility with Phil Talboys, head of European Test Operations for Jaguar, as well as a lap of the Nordshliefe with Sascha Bert, the Jaguar test driver who set the XK-RS lap record.
