Personally, I won't be the least bit surprised when we find out all the major American and Asian manufacturers do/did this same stuff and worse.
Ultimately I can't place total blame on the manufacturers, consumers demand emissions standards from their legislatures and then turn around and nearly bankrupt themselves buying 5000lbs extended cab trucks that says 24MPG on the sticker but realistically won't get more than 12 in real world conditions.
If you demand magic and are willing to pay $30k to get it, don't act the least bit surprised when someone lies to you
- masklinn 11y agoMost manufacturers aren't all-in on diesel, which was VW's strategy. They fudged the tests to have low-consumption during road tests but still pass NOx lab testing (NOx being a side-effect of good combustion in a diesel engine, which you want for better fuel efficiency and to limit particulate matter)
- Phlarp 11y agoThe the underlying technique used to fudge the test was that the ECU firmware behaved differently during testing than it would in the real world. I imagine the performance / efficiency curve can be similarly tweaked in a gasoline engine, allowing the OEMs to both pass the mandated emissions standards testing and still sell the kind of big boy truck consumers demand.
- masklinn 11y agoSure but I don't know that there's as much a need to tweak it to both pass emission tests and have good efficiency.
- mzs 11y agoYep, google Chrysler Lean Burn (which made sense back when they did it, allowed to avoid catalyst for a few more years) and more egregious GM Lean Cruise (which is now not permitted in US models).
