Randy Pobst is a very well known, and very fast race car driver. For the last few years in World Challenge, he has ran the K-Pax Volvo S60’s in GT class. I helped a friend with his World Challenge Scion tC’s that ran in TC class, which competed on track at the same time as Randy and his S60’s. Really nice guy, really fast driver. Motor Trend stuck him in a 2012 Nissan GT-R, 2011 Chevrolet Corvette, Z06, and a Shelby GT500 and set him free on the Streets of Willow Springs. The Streets is a very tight track, You really don’t get a chance to unwind a car like a GT-R. All three cars ran in the 1:20 range, with the GT-R on top. -edit the information in this chart for the Mustang's lap time is wrong - it should be -
Head over to the Motor Trend article for the full turn by turn breakdown from the track.
