2.9L Turbo Diesel?


Recommended Posts

The next engine option we may see in the US and definitely will see in Europe for the CTS is a 2.9L Turbo Diesel 6 cylinder putting out around 250hp and 406 ft-lbs of torque.

Would you be interested in a diesel Cadillac?

In my neighborhood, there is diesel fuel available at my local gas stations. Diesel there tends to cost MORE than premium fuel however. The DOE shows similar on average across the US: http://tonto.eia.doe.gov/oog/info/gdu/gasdiesel.asp

An average gallon of regular unleaded is $3.068 as of last Monday; an average gallon of diesel is $3.326.

Presumably the diesel CTS will get 20-25% better gas mileage, so instead of 18/26 city/highway might be rated for 20/30->22/32 city/highway or better.

So even at 8% higher cost if diesel saves 20-25% fuel, then it is a net savings.

With that much torque the 2.9T CTS should be a fun car to drive. Are you ready for a diesel Cadillac?

I'm definitely ready!

If you really want to make people safe drivers again then simply remove all the safety features from cars. No more seat belts, ABS brakes, traction control, air bags or stability control. No more anything. You'll see how quickly people will slow down and once again learn to drive like "normal" humans.

I am keen to test drive one. I think it would be fun if the diesel CTS were quicker 0-60 than the 304hp DI3.6L due to the greater torque.

I am guessing there will quickly be modified programming to boost the turbo settings for performance as well; have your cake and eat it too.

....Would you be interested in a diesel Cadillac?

Yes. As long as the engine is designed - intended to be a diesel burner (as this V6 obviously is).

We don't need another converted spark ignition to diesel fiasco; anyone else remember the 1980s and Oldsmobile "diesel" engines?

Diesel in Chicago is $ 3.79 a gallon,so I don't see any savings at all.

I don't understand GM would come up with this.

I'll bet anything they won't sell a lot of them.

And why would they get rid of the Northstar when that's what brought Cadillac out of the woods?

What are they thinking?

To sell cars in Europe, you must have a diesel engine. And if a diesel also sells in North America, it's icing on the cake.

I'd love a diesel Cadillac. On a different forum that I help moderate, for Chrysler minivans, we're clamoring for a diesel minivan. Europe has multiple diesel engines as options. There's no comparison in overall fuel cost, due to the better mileage. And the greater torque is really handy in a large vehicle. I think we'll see more and more diesels here as time goes on.

I was under the impression that diesels emitted higher emissions, is that true?

It's a complicated question. Diesel fuel in the US in now ultra-low sulfur fuel in order to minimize CO2 emissions. Modern engine use a variety of methods to minimize the characteristic particulate emissions as well.

I am still excited about flex fuel vehicles, which can use E85, or 85% ethanol fuel. Ethanol is attractive to me because it is a renewable fuel, and can be made from many source crops. Flex fuel engines are a fairly simple modification from base engines when done by the factory. It has the disadvantage of getting somewhat fewer miles per gallon than gas does.

Diesel engines can be modified to use bio-diesel fuel sources, such as recycled cooking oil, although we are unlikely to see Cadillacs modified in this way.

Wow, 250hp and 406 ft-lbs of torque more power than my 1982 6.2L Suburban that I use to pull a 6000 lb travel trailer. I get 30 mpg with this rig. What kind of fuel economy is this diesel CTS expected to get? One big advantage with a diesel powered rig is they get much better fuel economy around town. They don't operate under vacuum at idle and they don't go through the enrichment cycle during warm up. My diesel Suburban is much more economical around town than any one of my Cadillacs.
