And we have seen even more advancements in gas engines while hybrids are now mainstream. There are currently 5 different hybrids sold here that resoundingly beat VW
TDI's. Outside of range issues, diesel cannot compete with electricity in any way.

The Canadians don't hate us. They may be a bit jealous but they don't hate us.
Mostly all true, (I have run across some truly hateful Canucks), but our support of their oil market is still supporting the prices for everybody from whom we don't buy. If we don't pay them world market prices, they'll just sell to somebody else. So like it or not, buy that oil - support people who hate us. Don't forget our direct reliance on Hugo and the House of Saud.

Complete BS petrol isn't even close to diesel levels of fuel consumption let alone coming close to diesel torque levels, hybrids aren't any better either.
We've been through this (twice?). Those numbers look rosy until you compare the best gas with the best diesel across all lines. Comparing the gas engines of one manufacturer who has bet their farm on diesel with their less advanced gas engines is not relevant. Try Ford gas vs. VW
diesel. When I have more time, we'll look at the Chevy Cruze Eco which closely matches the TDIs without even using all the latest gas tricks.

Part of that is the government taxing diesel more heavily.
Accounts for less than 2%.
|Quoting BMI727 (Reply 13):|
By the way, the Audi Q7 TDI gets 4 mpg better than a Tahoe Hybrid. And it starts at almost exactly the same price.
Factually incorrect. Across the board. Again. The Tahoe hybrid beats the Audi in city and combined mileage and only 3 mpg less on highway. And, it's larger and more capable. Same with the Escalade hybrid. You should be embarrassed with that remark.
|Quoting ltbewr (Reply 11):|
ne reason to put more diesels into more vehicles in the USA is to meet Government's CAFE (corporate average fuel economy) standards.
And interestingly, Volkswagen AG
is the ONLY manufacturer adamantly opposed to the latest CAFE standards. Why do you think they are afraid of them? (serious question)
As they should be. Without the trucking industry, the entire country would come to a stop.

One factor that you missed - diesel engines generally have a much longer service life - provided they get vital oil changes ontime and use low-sulfur diesel fuel.
And their maintenance is also more expensive. Wait until Suzy Carbuyer finds out she needs to worry about her urea levels. "Urea? Isn't that urine??!!"
The one place where diesel will truly shine is as a generator for a series hybrid. Generate the electricity as needed. The motor will run at a constant speed where diesel is most efficient. Diesels have NO advantage in city driving.
Anybody who doubts anything I have said should be looking here. There are some interesting surprises in the data...http://www.fueleconomy.gov/
On another note, Chevy will sell a Cruze diesel next year. Here is what Bob Lutz has to say about it...
"Yeah, it’s almost impossible. We’ll do some because we’ve got them in Europe anyway, and we’ll make them compliant and GM will sell a few just to show that we’re part of the game. But I don’t think anyone sees much of a future for diesels in the states because our emissions regulations are six times tougher than Euro 5, and multiple times tougher than Euro 6, which nobody even knows how to do yet. The companies that are selling diesels in the United States, last time I checked which was over a year ago, are all operating on EPA deviations. So nobody meets even current diesel emissions standards. The EPA renews the deviations on an annual basis, but they’re not supposed to renew for more than three years.
It’s just so tough. You need the urea tank and everything, and in order to do the post-combustion NoX reduction in the catalyst, you have to deviate fuel to the catalyst because every two minutes a burn takes place to fry all the oxides of nitrogen and particulates. Well, that reduces the diesel advantage. So now you’re talking $2,500 of hardware and a big urea tank, and instead of a 30% gain in fuel economy, you’re looking more like 18% or 20% and you’re using a fuel that costs 18-20% more per gallon than gasoline. You tell me how this makes sense.
I mean, it’s cool. Owners of Volkswagon diesels love to go around saying [affects a voice dripping with self-satisfaction] “I have a turbodiesel,” and everyone says “wow.” But Ford canceled their passenger car diesel program, they canceled their midsized SUV diesel program, we canceled ours, we canceled passenger car diesels for the US. We were at one point talking to Honda to see if we could collaborate jointly on, say, a two-liter diesel for passenger cars, and we both came to the conclusion that it wasn’t worth the trip. They were hopeful (and frankly so were we) that with all they know about engine and emissions that they would be able to somehow conquer this emissions conundrum… they gave up. So all the major producers gave up on diesels for the US. http://www.thetruthaboutcars.com/201...be-a-game-changer-lutz-thinks-not/
