Im thinking a 3 litre or less, TDI or CDI turbocharged diesel V6 for the CTS. I think it would add more sales in light of these increasing petrol prices and make a better match for european markets while they're at it. Make it a clean buring one, with the latest in engine technology so it doesnt smell or burn bad... like the TDI that VW uses, which has no unpleasantness to it at all!

And I love diesel's so... im all for it. :bighead:


Its a smart idea, Europeans have been doing it... they either do a small 4 cylinder or go diesel. Cheap cheap cheap.

Like if GM will do that. For the trucks they have only 1 diesel.
I would loke to seea small 6 cyc diesel for their trucks.
They do have it for a Saab

shoot...how bout a hybrid V6 like the one Toyota has for the Lexus RX400h!

There is some great diesel technology now, but I'm not sure why automakers aren't jumping on it more. Common rail technology and computer controlled multi-pulse injectors make diesels quieter, less polluting, and more responsive. Modern diesels are more fuel efficient than hybrids. Diesel fuel around here is $1.80 a gallon vs. >$2.00 a gallon for unleaded regular. But, what diesel vehicles are there in the American market?

- VW Golf & Jetta TDI
- MB E320 CDI (newly re-introduced)
- GM, Ford, & Dodge HD pickups, but none of the diesels are made by the automaker (GM's Duramax is closest being a joint venture with Isuzu.)
- Ford Excursion & E350 van (same engine as the pickup)
- Hummer H1 (with a GM 6.5 diesel)
- Jeep Liberty CRD (2005 model, not yet available)
- GM Suburban, 3500 van, and H2 (possible future diesel options).

Maybe the lack of diesel models have to do with the reformulated diesel fuel being required in 2006 or so. I heard that the new diesel has a lot less lubricating properties than current diesel fuel.

we could be running boi-desel which is made with corn, give the money to the farms

Detroit Diesel, Cummins Diesel and International / Navistar Inc. Only cummins and navistar have been used so far in automobile products...

The Ford Superduty series (including E250,350+), Dodge Ram 2500/3500. The smallest engines that cummins and navistar make, are able to fit in these trucks. IF any one else wanted to, they would have to make an engine compartment in the car able to hold a 6 litre plus I-6 or V8.

Its a size and application issue.

GM use to make their own diesels, the 5.7 in early years and then the newer 6.5 last used in the H1, 2500 Suburban and C/K trucks.

The question for Cadillac would be, is it that hard to create a new diesel engine with the profit gain they've been getting? And would it sell to the public?

'Got excited over the 2.7 CRD Liberty comming out as C5 mentioned... we have yet to see if that sells. But what if it works? What will everyone do next?

The idea of Cadillac creating a diesel for the CTS or any other car probably wont work... just how americans are when it comes to their cars. :tisk: It will get interesting in the future though, prices are going to rise... and we may have to give Diesel one last try.

(Oh and btw, prices here are 1.93 regular, 2.03 super 2.11 for premium)

You're lucky. It's 2.09 regular, 2.19 medium, 2.29 premium here in Southeast Michigan.

Prices are still raising here, so its going to get there soon..

There are four American companies...you forgot the biggest diesel engine manufacturer in the world....Caterpillar. 60 to 70% of the trucks you see on the road have Cat engines. Let alone the countless pieces of construction equipment, etc.

http://www.cat.com/products/engines_n_power_systems/engines_n_power_systems.html

Caterpillar makes everything from 10 HP up to 13,600 HP. Whether a diesel engine will physically fit (Cat makes several that would) is a minor issue compared to will the transmission handle the tremendous torque output (maybe a T-56 would) and the biggest factor of all - cost. Would you pay $6 - 10,000 over the price of a CTS today if it had a Caterpillar diesel engine? A $50,000 diesel CTS or for the same price, have a CTS-V? Decisions, decisions....

For a diesel, long term durability is excellent, along with fuel economy, but one would probably have to put over 300,000 miles on a diesel powered CTS to recoup the upfront engine cost.

Here is a site for different diesel engine

:rolleyes2 I drive a '99 VW Beetle, 1.9L Turbo Diesel. Averages about 45 MPG, can go about 700 miles on tank. It's the second VW diesel I've had. Plan to get a 2005 when they come out. GET SOOT! I love it! I'd buy a CTS with a diesel, as long as they (GM) didn't make the same mistakes they made with the converted diesels from '78 through the mid eighties.

Car and Driver came out with a great article about diesel vehicles (http://www.caranddriver.com/article.asp?section_id=4&article_id=7816&page_number=1). The article talked about the technology, the potential for diesel in U.S. markets, and four vehicles with diesel engines ranging from 4cyl to 10 cyl.

One of the facts that stood out for me besides great mileage and the increased use of technology to reduce soot and other diesel ailments was that diesel engines similar in size to regular gas engines produce gobs of torque. That translates to stealthy city driving. Listen to these figures:

PT Crusier Touring CRD: 119hp/229lb-ft
Mercedes-Benz E320 CDI: 201hp/369lb-ft
Audi A8 4.0 TDI: 271hp/479lb-ft
VW Touareg V-10 TDI: 308hp/553lb-ft

All but the PT outgunned their gas engine counterparts in 0-60 times and the 1/4 mi. Nevertheless, every car ran impressive 30-50mph and 50-70mph times and in every case outgunned their gas engine counterparts.

Diesel engines perform differently than gas engines. The article sums it up nicely:

" Their power delivery runs inversely to that of a typical overhead-cam gas motor. With high torque that peaks way down low (1600 rpm in the PT) and only modest power that also peaks low (4200 rpm in the PT), the pressure on one's backside maxes out early and tapers off rapidly in each gear, instead of building steadily to a peak well above 5000 rpm as in most gas engines. Diesels also tend to resist matched-rev throttle blips, being slow to rev and ultra-quick to return to idle, so our boy racers were vexed in some corners on the handling loop."

This is something to consider when buying a diesel.

But the thing is, you do pay it off with lower fuel prices ... less mant. and greater reliabillity.

ford pickups came with cat diesels at one point , before they started shoveing the interantional/navisatr crap down our throats

welcome volkswagen dude , last one i drove was a 98 tdi jetta , went over 600 miles on a tankful in alaska , was nice to go from fiarbanks to anchorige and back on a tankload , and stil have enough to go to work for the week

in reality the GM duramax is a isuzu diesel design , also a damned good diesel producer

anyone know if penske still owns detroit diesel ?

Penske & GM owned Detroit Diesel under a joint venture from 1988 to 2000.

In October 2000, DiamlerChrysler bought their shares and now owns 100% of Detroit Diesel.
