After a day behind the wheel of the new GMC Acadia crossover SUV, the folks at Popular Mechanics report some new information that snuck out in a conversation with a particularly chatty GM staffer.

He revealed that the Acadia will get the Denali treatment and, along with the usual trim level upgrades, a V8. The more interesting news is that the V8 under the hood of the Acadia Denali, and most assuredly the Buick Enclave as well, will be from an entirely new engine family being developed for transverse applications.

He stopped short of giving up specs, but the 3.6-liter V6 as tuned for use in the new crossovers makes 275 horsepower, so figure 300+ for sure. Hey General, how about 400?

Thanks to Ben at Popular Mechanics for the heads-up!

      --->#8. Come on GM! We all need SUV's with 400+ horsepower and that weigh 5000lbs.

      Hey, you just described the Porsche Cayenne.

      Agree with "uncle john", slam the domestics, and pat the imports on the back for doing the same damn thing.

      I am not into SUVs, but Me thinks me like.

      I'll see your 400 horsepower and raise it to 450 hp; no make that 500 hp; hey, why stop at that, lets see an Acadia with 550 hp! Wow, won't the little children riding in back be impressed when Dad does doughnuts in front of all the impressed neighbors. Come on GM! We all need SUV's with 400+ horsepower and that weigh 5000lbs.

      #4 - I don't have a problem with GM offering a V8 in the Acadia - the General has some great V8 engines. But its inaccurate to say the Acadia will get 25-26mpg - since when does *any* crossover get EPA numbers? Never. As much as we enjoy knocking CR here, they do post more reasonable mileage expectations - Highlander/Pilot/Murano average 18-19mpg in combined driving, thats what I would expect for the Acadia as well. Not as high as you claim, but still quite reasonable compared to truck based SUVs like the Jeep Commander or Land Rover LR3 (both of which struggle to get 15mpg on the highway according to Edmunds Long Term tests).

      It is a great idea that GMC should offer an Acadia Denali with a V8. Buick should also offer a V8 powered Enclave Super and a V8 could be added to the Saturn Outlook as well. Maybe they'll debut at a major auto show soon.

      "Wow, won't the little children riding in back be impressed when Dad does doughnuts in front of all the impressed neighbors."

      It's even better when you hear their heads hit the head rests, and see their lips fold back under acceleration in the mirror.

      Anyways, onto non-automaker bickering...a new engine line being developed for transverse operation, including V8s? I forget, is the Arcadia/Enclave primarily a FWD vehicle? I'm assuming as much with the transverse deal, but is this engine line all new? Or codeveloped with the new high feature V6's? And is Caddilac in on this to replace their transverse Northstars? It doesn't make much sense to develope multiple engine lines when a more universal and adaptable (FWD/RWD/AWD capable) engine line would more appropriately help with parts sharing, dev costs, and economies of scale.

      Would you say that about Mercedes? BMW? Audi? Oh, I see, gas guzzlers must be endemic of GM only. Everybody else gets a free pass. Tell me, is this really Ryan in disguise?

      You don't need to develop a "new engine line" for transverse operation. GM currently has 2 transverse capable V-8's in it's hands that they could use, and development of any other 8's isn't all that difficult, Chrysler has been doing it with V-6's for years.

      Transverse V8 for FWD biased AWD? What a waste.
      • 8 Years Ago
      The Outlook and Acadia get 25mpg w/ awd and 26 w/ fwd in a V-6. They get great gas mileage. Nobody comes close. If one doesn't like the V-8, don't get it.

      That said, it will still probably get 22 plus with a V-8 considering the heavier Tahoe gets 22.

      Also rumoured is a 2-mode hybrid system paired with the V-6.
