As Predicted Here 2 Years Ago, More Diesel Emissions Cheating Alleged

Back in November of 2015 I wrote:

I would be stunned if the Volkswagen emissions cheating is limited to Volkswagen.  Volkswagen is not unique — Cat and I think Cummins were busted a while back for the same thing.  US automakers don’t have a lot of exposure to diesels (except for pickup trucks) but my guess is that something similar was ubiquitous.

My thinking was that the Cat, Cummins, and VW cheating incidents all demonstrated that automakers had hit a wall on diesel emissions compliance — the regulations had gone beyond what automakers could comply with and still provide consumers with an acceptable level of performance.

Since then Fiat-Chrysler has been accused of the same behavior, and now GM is accused as well, though only in  a civil suit.

A class-action lawsuit accuses General Motors of rigging emission-control systems on 2011–2016 Chevrolet Silverado HD and GMC Sierra HD pickups with GM’s Duramax turbo-diesel 6.6-liter V-8 engine. If the allegations are proved true, the environmental damage from these 705,000 trucks, which the lawsuit said emit two to five times the legal limit of nitrogen oxides (NOx) in typical driving conditions, could easily exceed that of Volkswagen’s emission-test-cheating TDI engines.

Of course, people can say any thing they want in a civil suit, so this needs to be proved, but I think it probably is true.

A while back a reader with some inside knowledge explained what was going on.
