Right, they’re not identical, but there are a lot of similarities in their construction and basic principles. Variation on a theme, if you will.

Yep, I had to add a second reply to add that I wasn’t coming to the defense of the cheaters, just to the viability of diesel as efficient, clean transportation.

That’s pretty bad ass!

I’m sure that’s part of it, but especially being a dry clutch, they should know better than to program it to slip the clutches as much as they do. That’s just bad juju all around.

Yeah, they kind of are. The type of gears and the selectors work just like a manual transmission. The fact that the clutches have to do 100% of the work to transmit the power between engine and transmission is also just like a manual instead of having a torque converter.

As someone who’s enjoyed VW DSGs since they came out (earliest model I’ve seen in the U.S. is in the 2004 New Beetle TDI) I was excited when I saw Ford coming out with a similar concept a number of years later.

“Great!” I thought. “Better efficiency, more linear engine response like a real manual transmission,…

It’s too bad they likely won’t tell you the results of said testing. Would be interesting to see the results.

They are not emitting the same particulates, though. The carbon particles are 99% trapped in the substrate and when it goes through a regen cycle, it burns the carbon/soot and converts it into ash, which stays trapped in the filter effectively forever. Eventually, after a few hundred thousand miles on average, the ash…

Complete garbage article full of factual errors.

Reduce consumption of the limited resource that is oil? Pump less CO2 into the air?

Yeah, I’ve gotten there too... the roads are becoming worse as well, especially where the Big 3 are headquartered.

Gonna go all “AND ANOTHER THING!” here again.

While I’m here ranting, I might as well throw this in for good measure, not necessarily aimed at Mr. Kitman, just automotive journalists at large who seem to get this wrong nearly every time:

I’ll leave this here. https://www.carcomplaints.com/news/2019/bmw-diesel-emissions-lawsuit-dismissed.shtml

I. Don’t. Care.

I wrote another reply that spells a lot of it out. In the U.S., CO2 is not considered a pollutant and thus is not regulated. At least not directly. Since CO2 does have a direct relationship with amount of fuel burned, I suppose CAFE fuel economy standards sort of work to curb CO2 output... indirectly. CO2 is a climate…

Read my reply for a more accurate assessment of emissions.

His counterpoint is to simply point out that efficiency and CO2 output is still an important goal, and if climate change is a bigger, more important goal to control than local air quality, then maybe going a little easy on a technology that reduces CO2 isn’t a bad thing.

I will add to my previous statement that my defense of diesels and the general explanation of the technical realities involved therein are not an attempt to exonerate the cheaters. VW and FCA got proper punishment for their cheating and deservedly so.

Typical lawyer/journalist, doesn’t actually fully grasp the technical realities at play here.
