## Resource

Ten years ago, INTC's Jeff Braun helped a Japanese carmaker go IMSA racing with a 180-mph diesel prototype. The car was cool. More than 700 lb-ft of torque at 2800 rpm. Gobs of potential. Also: It blew up every five minutes. (An exaggeration, of course. No race car blows up every five minutes, even an underfunded, production-based coal-roller cranking around Daytona. That would be silly.) (It was probably more like ten minutes.) Mazda's diesel Le Mans prototypes of 2014 and 2015 were one of the most admirable, ambitious, and ill-fated efforts in American motorsport. Jeff was on pit wall for the thick of it, helping make those cars faster. Sam is here now, asking questions. This show changes format weekly, because squirrel. We call this format “JEFF TELLS A STORY.” This episode was produced by Sam Smith.
