Diesels Still Needed For Truck Fuel Economy Despite VW Scandal: Advocate

Allen Schaeffer probably doesn't have the easiest job these days.

He's executive director of the Diesel Technology Forum, a non-profit organization dedicated to raising awareness about the importance of diesel engines, fuel, and technology.

With the Volkswagen diesel-emission scandal soon to enter its sixth month with no signs of resolution, Green Car Reports reached out to Schaeffer for his take on the state of diesels in the U.S.

"There's no question that the VW situation hit the pause button on the diesel passenger-car market in the U.S.," Schaeffer told us.

But, he suggested, it's important to understand two points about the use of diesel engines in road vehicles.

First, diesels will continue unaffected in large commercial trucks--everything from "box vans" for local deliveries through the largest semi tractors for highway freight hauling.

That's because there's no immediate alternative for some of those uses, especially long-haul freight.

And, the same likely applies to diesels in light-duty pickup trucks and perhaps high-end sport-utility vehicles as well.

Passenger cars like those mostly sold by VW may be a different matter, he acknowledged.

But the second point to keep in mind, he said, is that the Corporate Average Fuel Economy requirements through 2025 haven't changed--regardless of the VW scandal.

And automakers continue to view more-efficient diesel engines as one method of meeting those requirements, especially in pickup trucks.

Schaeffer pointed to the popularity of the Ram 1500 EcoDiesel, which Fiat Chrysler has said will make up 20 percent of the model's sales. He also noted the well-received diesel versions of the Chevy Colorado and GMC Canyon mid-size pickups.

Rumors that Ford is planning to launch a diesel version of its high-volume F-150 pickup only underscore that point.

Even in passenger cars, Schaeffer said, so far "no other maker has hit the pause button" on its diesel cars--although Audi and Porsche have suspended sales of all their new diesel vehicles, which use VW Group engines.

(Porsche acknowledged yesterday that it had put a planned diesel version of its Macan compact SUV on hold until the crisis is resolved, but said customer reaction to that model had been very positive.)

And, he noted, a handful of the latest diesel vehicles are already "close to the mark today in fuel economy and carbon emissions" that will be required across the fleet by 2025.

The Diesel Technology Forum has surveyed car buyers since the scandal broke, Schaeffer said, and found that "the average person hasn't heard about it."

Of the smaller group who can articulate the issue, he said, the most common view is that it's "cheating" by a specific maker, not an indictment of diesel technology overall.
