GM's truck operation, if you were to separate it from the rest of the company, would be one of the most profitable automotive ventures in the world. So, perhaps you can understand why so much one-upmanship goes on between the truck brands. Working to keep Chevrolet and GMC on the cutting edge is Jeff Luke, the Executive Chief Engineer of GM Full-Size Trucks. He'll be our special guest this week and we'll be asking what technologies GM is looking at -- CNG? LPG? Turbocharging? Light-duty diesel? As usual, we'll also get into the biggest news of the week: Nissan sets an ambitious goal for achieving autonomy, Carlos Tavares gets the boot from Renault, and VW protests a lack of diesel incentives. Joining host John McElroy in studio is Peter De Lorenzo, the Autoextremist, and Gary Vasilash from Automotive Design and Production.
