GM's new head of powertrain 'loves' diesels

Kiefer arrived at GM last September after a long stint at Delphi Automotive, where he finished up as senior vice-president of powertrain systems.

It’s unclear at this point if GM will quickly roll out a diesel in its Silverado and Sierra or if it will downsize its engines.

Kiefer brings to GM a great view of the industry. From his Delphi days when he met regularly with the powertrain chiefs of most major automakers, he knows what technologies his competitors are investing in to boost fuel economy and lower emissions.

On the powertrain front, GM has been a bit rudderless in recent years, especially after its former vice president, Tom Stephens, retired. Now there’s a new Scotty in GM’s engine room. He’s open-minded to all technologies and he’s passionate about the job.

That’s good. Because 2025 and the mandated 54.5 mpg standards are looming.
