"VW claimed to have figured out how to meet the standards without needing AdBlue," said Kirk Wennerstrom, marketing director of the Greenwich Concours d'Elegance, a vintage and classic car show in Greenwich, Conn. "Everyone else must've been scratching their heads trying to figure out how. I'm certain more than a few competitors have reverse-engineered VW cars to figure it out."
While VW did initially pursue an "AdBlue" solution, it soon figured out it would've cost about $300 more per vehicle to add it, Wennerstrom said. "I suspect the truth about that cost is a bit more nuanced. The cost to VW may have been $300, but the cost to the consumer would've been a few thousand dollars," he added.
What VW wasn't telling anyone is that it hadn't really figured out a way to reduce NOx without AdBlue, but instead embedded software to turn on emissions control systems only when a vehicle was being tested.
The company said this week it is now going to switch all diesels over to "Selective Catalytic Reduction" systems that use AdBlue technology in Europe and North America "as soon as possible.
"Diesel vehicles will only be equipped with exhaust emissions systems that use the best environmental technology," VW said.
