I was happy to read in this sundays NYT automobile section that Audi, MB and BMW will be offering 4 and 6 cyl turbo diesels across their product lines. All Audi models will offer the diesel variant in 2014, even the big A-8 and A-7 sedans, plus Q-5's and A-4's and with 4WD.
MB to add C Class and GLK diesels to the E and S classes.
That's good news.
There was also an article on the Chevy - Cruise 4 cyl diesel sedan that's on sale now and gets 48 mpg hi-way.
Finally they are beginning to see it our way !!!
Interesting note was that VW/Audi has the only 4 cyl diesel that is 50 state legal WITHOUT needing the urea tank system.
Better engineering ?
