Cadillac mulling V8 diesel for CTS

According to MotorTrend, General Motors is considering fitting its 4.5-liter Duramax V8 Turbodiesel inside the Cadillac CTS sedan as a stepping-stone between the standard V6-equipped CTS and the barn-burning CTS-V.
The report contends that the Duramax V8 would be an easy fit inside the confines of the CTS' engine bay with the addition of the CTS-V's bulging hood. The dual-overhead cam, four-valve diesel V8 puts out 310 hp and a tire decimating 520 lb.-ft. of torque and GM already has a transmission that can handle the grunt. The oilburner currently meets the tougher 2010 emissions standards which would allow it to be sold in all 50 states, and with a reported 20-25% increased fuel economy over the V8 model, the diesel CTS could provide some competition to similar offerings from Audi, BMW and Mercedes-Benz. According to MT, the amount of modifications would be minimal and the addition of the CTS diesel would help to boost GM's CAFE certification to meet the stricter 35 mpg requirements in 2020.

Yes it would be nice, but i do not get the CAFE side of it. Caddy sells only a few thousand units per years, CTS-V is probably one of the lowest sellers (by volume) so what is the point of giving it a very efficient engine. You can achieve a far better CAFE score by getting .5 MPG from Cruze or Malibu.
I do understand this from driving point of view (fun) and even from business, because this engine could be passed on to other cars (Camaro,G8)

chop off two cylinders and you have a CTS that will get 40mpg=?
huh, sounds like GM should offer both versions

Now we are talking!
Drop the standard CTS Gas 6
Replace it with a Turbo Diesel 6
Mid Range Diesel V8
CTS-V
No way in hell that will happen but I would be pleased if it did!

This is a great idea. I would love to have more diesel offerings in passenger cars...especially American ones.

GM can afford to think about something? Sheesh, I thought they were too broke to even do that.

Nice idea, but what about a turbocharged version of the already excellent 3.6DI i have in my CTS??

I'd rather have a 'sane' diesel -- say around 350lb/ft and get even better mileage.
But yes, very good idea.

Yeap like the twin turbo 3.0l v6 diesel BMW have
That 4.5 Duramax is ancient by today standards.
Holden Miecranc 9:44AM (10/15/2008)
Beastage,
The 4.5 Duramax, which hasn't even entered the market yet, is "ancient by today's standards"? You gotta be kidding me.

No. Not at all like that. First of all it's not a V6.
I like the idea. It's more efficient and more torquey than the gas engine. Plus getting more from a tank and filling up less is good for perceptions. It may have little CAFE effect but the owners will be happy.

Build it. NOW. This is a no-brainer.

Cadillac needs to offer a diesel if it wants to compete with the Germans. GM, don't drag your feet on this one like the Camaro. Just get it done already

Speaking of Camaro, just go ahead and put it in there too.
Thanks.

Just DO IT. Don't mull it over, just plop it in there and put it on lots.
