They're all expected to hit dealerships in 2013

Audi is going crazy for diesels as it gears up to release four new TDI clean diesel models in the U.S. throughout 2013. 

Audi has announced that it will be releasing the Audi A8 TDI, Audi A7 TDI, Audi A6 TDI and Audi Q5 TDI next year. All four models are part of Audi's TDI clean diesel engine lineup, and they debuted at the Los Angeles Auto Show. 

According to Audi, each of the TDI vehicles offer 30 percent greater fuel economy and 30 percent reduced carbon dioxide emissions than gasoline engines. 

Audi A7

“Owners of Audi TDI engines have helped save over 4 million gallons of gasoline, or the equivalent of more than 240,000 barrels of foreign oil, since the introduction of Audi TDI to the U.S. in 2009,” said Scott Keogh, President, Audi of America. ” And, TDI technology delivers better fuel efficiency without sacrificing performance.”

All four models will have Audi's 3.0-liter V6 turbocharged diesel engine, which offers 240 HP and 406 lb.-ft. of torque. 

In the A8 TDI, which is Audi's flagship sedan, the vehicle's set up is expected to return 24 MPG city and 36 MPG highway. The Audi Q7 TDI, which has been available since September 2012, gets 19 MPG city and 28 MPG highway. 

While there's no word on pricing quite yet, the A8 TDI will make its way to dealerships in the U.S. in Spring 2013 while the A7 TDI, A6 TDI and Q5 TDI will all come later in Fall 2013.

still waiting for better fuel

Europe has higher cetane fuel. The US standard is not only just 40 or greater, but the wear scar is 520 microns or less.

Bosch and others in the Engine Manufacturers' Association have put out papers and statements repeatedly that the wear scar should be no greater than 460 microns.

Also, as far as I know, car drivers here are paying fuel taxes designed to compensate for road damage from large diesel trucks. As long as diesel is 75-110 cents more per gallon, it is going to be less attractive for car buyers — although Audi buyers probably won't care as much as VW buyers.

Sure... and my TDI wasn't made in Mexico. Wait, you are wrong again.

Perception versus reality. Owners of modern diesels (unlike you apparently) would argue there is little diesel specific maintenance and the benefits outweigh whatever incremental cost difference per gallon there is. After Hurricane Sandy, diesel was the only fuel readily available in nj. Plus, it worked as a shady tree generator for cell phones and laptops. Left it idle on/off for 6 hours and the fuel needle never moved. Yee haw!

After 140,000 miles on my TDI, the only thing that has ever needed diesel specific changing has been the fuel filter. Looking back, it had more to do with running the tank empty versus filling at 1/4.

Ummm... having driven a diesel for 13 years in the US, I think it's pretty funny to keep hearing that same old urban legend about diesel taxes. You can look up the taxes on gas & diesel, and if you do, you'll find there's almost no difference between them - it's a myth perpetrated by the oil companies to make you blame the government when it's the oil companies themselves that set the price of diesel higher by choice. THEY are the ones screwing over diesel car owners.

The Federal tax is 18.4 cents/gal on gas, 22.4 cents/gal on diesel. Here are a few states total fuel taxes (State & Federal):

NY: 69.7 gas, 74.7 diesel
TX: 38.4 gas, 44.4 diesel
CA: 68.9 gas, 77.1 diesel

... so that's 5 cents more in NY, and 8.2 cents in CA - So much for Urban Legends!!

8.2 cents extra per gallon constitutes an "urban legend"?

No, but 75 to 110 cents per gallon more sure is.

Make friends with a farmer and buy diesel from him. (It's not taxed the same.)

And while technically legal, the end result is the same: you avoid paying pay taxes levied for the repair and maintenance of the roadways you use. So legal, just not fair.

The more government tries to "nudge" us in a particular direction the more holes they create. The less they screw with it the better things are.

Your moral equivilancy arguement is weak. Look how much they raise in fuel road taxes and how much of it actually goes to the roads. Most states put it in their general fund and it disapears from there. Is that "fair" to those who buy fuel and expect it to fix the roads?

I know a bloke here that makes Diesel from oil that he gets for free from the fish and chip shops. - He hasn't paid for fuel in half a century.
The shops love it as they don't have to pay anything to get rid of the oil. :)

I'm pretty sure the bloke you know isn't making Diesel but rather he is taking advantage of how a Diesel car can run on other types of fuel (which is pretty handy).

Actually, he probably is making diesel through transesterification. It's called bio-diesel, and people really do home-brew it. It's not as simple a process as even the people making it seem to believe though. It's reversible, and I think this guys friend would find his diesel would never pass EN 14214 standards set for the European Union.

And risk the DoT sticking my tanks and finding "red" thank you.

I admit it is tempting, especially as my F-550 holds right at 180 gallons across 3 tanks, and the bill really, really sucks. But, I was stick'd 3 times over 10 years while living in Tucson and once in the last 8 while here in Ohio. If I got caught running agricultural diesel the fines would far exceed any savings I could ever hope for.

Where's the A4? Sell an A4 avant TDI here with manual transmission and I'll buy one immediately. Although this is good news that their putting TDI's into more models for the US. I drove an A4 with the older 2.7 TDI in europe a few years ago, and the torque was bone crushing, it was amazing to drive.

A TDI motor is coming with the next generation B9 A4. The current B8 generation won't get it.

It was rumored earlier this year the Passat would get the new motor as well. That car is underpowered with the 2.0 TDI already.

Ideally, VW would drop the 3.6 and swap it with the 3.0 TDI And keep the current gasser for lamers.

Underpowered? Maybe, but the available low-RPM torque makes the everyday driving experience at least as good as the gas versions, and none of them can approach the 40-50 mpg that the Passat TDI returns. Sure it's a tradeoff, but it's hard to comprehend this efficiency in a full-size auto; plus an 800 mile driving range is ridiculous.

You don't need to sacrifice power for an 800 mile driving range.
Don't know if you remember the Top Gear episode - Series 4 Episode 4.

Clarkson drives an Audi A8 TDI - the V8, yes, a 4 litre 275hp/480lb-ft (later replaced by an even faster 4.2l) 800 miles on a 20 gallon tank.

Before you get excited remember that Clarkson always quotes stuff in imperial gallons cause he's English. The American gallon is 20% bigger so the mileage sounds 20% better in the UK.

Still an expensive toy for the rich

Wake me up when I can buy modern common rail turbo diesel car for the same price as say Toyota Yaris, 14k or so. Until then the large difference in price between diesel and gas engines (plus diesel being more expensive than gas) makes buying diesel car a stupid idea that works well only for the rich people who don't know where to waste gobs of money they have lying around. Instead of flushing their money down the toilet they buy diesels. Sounds like the same thing to me.

Well... Got my used 2009 Jetta TDI for 21k, it had about 40000km on it, not even broken in for a diesel. I get over 800km on a 55l tank in the city, and about 1100 plus on the hwy. I only need an oil change every 15000 km to keep warranty (I usually do one every ten). I can re flash the ecu, and go to 330 ft/lb of torque at about 1800 rpm, will once my bumper to bumper Warr is done. And I can increase fuel mileage by cutting out the 170lb DPF when I flash it. However, I don't plan to go that far unless some nasty dpf maintenance comes up in like 3-4 years.

The 140hp its rated at is a bit of an inside joke, because of the torque that's early and plentiful. I climb thru the rockies in 6th if I feel like it, as I am not having to downshift. Unlike my WRX, I don't have to be screaming along with high revs to have power. It's just there.

Until I can get myself a volt type power train, TDIs are pretty darn close to that solid high efficiency high torque drive that is really very nice.

As to diesel bearing a higher tax burden then gas, wouldn't that make sense if fuel is taxed by its energy content?

Also my running avg via fuelly is 5.9 l / 100 km. My best tank was 5l/100km.... Not bad at all. Especially with pretty much dick all for maintenance.

That's all nice and dandy but even if fuel economy vs fuel price gives us approximate parity between money spent per mile in diesel vs gas, even then gas cars are still cheaper than diesels so still doesn't make any economical sense to buy them.

Also my running avg fuel econ. is 5.9 l / 100 km.
5.9 l / 100 km = 39.8668785 miles / US gallon.
Ran that through Google calc for the 'Murricans. Doesn't actually sound super-impressive.
