Why take the risk? What makes you think it would work this time? We're asking, of course, about GM's relationship with the long-embattled diesel engine. Decades after the General killed diesels in passenger cars, Chevrolet is counting on a reversal in fortunes as it offers the Cruze with a modern diesel powerplant. This week as Mike Siegrist, Assistant Chief Engineer of the Chevy Cruze Diesel, joins us in studio with an engine in tow, we'll ask him why the company is putting its faith in diesel once again. As usual, we'll get into the latest news including Viper returning to Le Mans and Renault entering Formula E. Joining John McElroy in studio is co-host Peter De Lorenzo, the Autoextremist, and Gary Vasilash from Automotive Design and Production.
