please build the CTS TT36!

Turbo is the future. Not only in diesel, but also in petrol.
Fill the gap between 300 and 550 hp with a 400-ish TT36

...and I will take the CTS Coupe TT36!

[asrapid]

yeah..that would be a smart thing to do. So GM probably won't do it. Rumors are they've cancel works on future V6 TT

[thebigjimsho]

How is that guaranteed "smart"? There's a TON of R&D work to make a production TT engine that will go in enough applications to make it viable. 300 is enough for 90% of the buying public. Having an expensive 400hp AND a 568hp engine at the ready doesn't sound particularly smart...when GM is losing billions.

And my LS6 V with headers and a tune averaged 25mpg doing 2,000 miles to Chicago and back from Boston. I doubt a TT V6 is going to do any better...

What 400 HP? New Cadillac CTS doesn't has 400 HP and competition (here in Europe competition to cadillac cts is bmw 5 and E class offer engine with much more then 300 hp). They beat m5 and E amg (true they are old cars and replacement should come soon) in HP but they still got big hole between 300 and 570 HP. True most people don't need that much HP...but most people don't need Bmw with 400+ or mercedes with same hp and they both make that kind of car. It is image thing. Something what cadillac is losing..and will continue to lose as long as there isn't money to continue R&D TT V6 v8 and competitor to S class. And in class which cadillac is aiming at image play big role.
I also doubt we will see LS3 coming between V and DI V6 also (there was old text on internet where Lutz ..i think it was Lutz...said something like there won't be any future ohv engines in cadillac after MCE of present CTS).That was before ultra v8 was cancelled.
Not to mention that diesel engine should come from the start.

Audi is going V6 turbo, BMW is going 6 cyl and V8 turbo and Mercedes is going V6 and V8 Turbo. Also Alfa Romeo is now slowly chiming in in that market with v6 turbo and all other brands who wants a share in the market is going v6 turbo.
Why? Because you'll have V8 power in a fuel efficient V6. I bet you a TT36 will have a better mileage than a regular 3.6 or 3.6 DI on that same 2000 miles trip!

If Cadillac wants a share, they better play along...

You can try to make the case that a TT V6 will get better gas mileage than a V8(which will NOT happen on-boost), although a high hp V8 can make use of ultra tall gearing ala CTS-V and Corvette(25mpg on my '04 V without even trying). But I find it hard to believe that a TT version of an engine will EVER get better mpg than the NA of same said engine.

[70eldo]

Combined mileage of a Turbo over a non-turbo same size engine will always be better, as the combustion is more efficient. Plus you get the extra power boost.

I agree on your 25mpg with a V or Corvette (the C6 even gets better than that), but a V8 will always lose on combined mileage, as the urban-mileage will be significantly worse than a V6.

Or at least it won't make a difference in mileage, but you do get more power. Example:

BMW 228I and 335i (both 3.0 liter engine) have exact same mileage.

Even Ford is going V6 3.5 TT

GM can put the TT36 in so many cars...
