Car and Driver: VW Says It Can Fix 3.0-liter V-6 Diesels, Looks to Avoid Buy-Back

Volkswagen, which just announced a profit-crushing, $14.7-billion settlement for its emissions-cheating 2.0-liter four-cylinder diesel engines, is still holding out hope that its V-6 TDI models can be brought into compliance, thus avoiding another multi-billion-dollar buyback.

According to Reuters, a lawyer for VW made the assertion in court June 30. The emissions problems affecting the V-6 cars are less severe and smaller in scope than those with the four-cylinder models. The report states that while the 3.0-liter diesels can emit up to nine times the legal limit of pollutants, they do not have the cheat software that switched on emissions controls only for EPA testing, turning them off at other times, which allowed the smaller engines to spew some 40-times the legal level of nitrous-oxides (NOx).

“The company believes that we can fix the 3.0-liter to the standards to which those cars were originally certified,” VW’s lawyer is quoted as saying, and also that the fix would not be complicated or adversely affect vehicle performance. The 3.0-liter TDI was installed not only in VW’s Touareg, but was used also in the Porsche Cayenne, and Audi’s Q5, Q7, A6, A7, and A8. It’s not known whether the proposed fix would allow those models to once again be sold—all have been on stop-sale since last fall. The next hearing for an update on VW’s progress is set for August 25.
