GM Revved for New Aluminum V-10 Engine in 2007

General Motors Corp. is developing a V-10 gasoline engine for use in some of its biggest sport utility vehicles, pickup trucks and crossover vehicles starting in 2007, with both an all-aluminum version and an iron-block model planned, American Metal Market reported April 17, 2003.

The aluminum versions could enter the market with 210 pounds or more apiece of finished aluminum components, company sources said. The Detroit-based automaker doesn't currently build an engine with that much aluminum.

GM sources said the V-10s are intended for use in such vehicles as the Cadillac Escalade, an SUV, and the Escalade EXT, a sport utility truck with a cargo box at the rear. Those vehicles are available with V-8 engines only, as GM doesn't currently have a V-10 in its product line.

As power options in those vehicles, the big automaker figures the 10-cylinder units will attract more Cadillac buyers and enable the company to increase its share of the luxury truck market. As conceived, the V-10s are overhead-valve (OHV) units based on GM's existing 4.8- to 6.0-liter small-block V-8s.

The V-10 is a separate design from the Cadillac Cien V-12 concept engine introduced last year, a GM source said. That engine was based on the dual-overhead-cam Northstar V-8. The V-10 also is smaller, and considered to be more practical, than the OHV V-16 concept engine introduced early this year by GM in its experimental supercar, the Cadillac Sixteen.

The V-16 is not a viable candidate for production, GM sources said, but the DOHC V-12 is. However, the V-12, which is also all aluminum, is more likely to be used in cars than trucks and is not as close to production as the V-10, one GM source said.

Although GM's plans for the V-10 represent good news for the aluminum industry, they could get the big automaker into more trouble with energy conservationists and environmentalists.

GM recently took a position against any increase--even the modest uptick of 1.5 miles per gallon ordered by the National Highway Traffic Safety Administration--in federal fuel economy standards for light-duty trucks, saying, among other things, that an increase would cost the automaker too much money (AMM, March 10).

GM does intend to team the V-10s up with a new rear-wheel-drive six-speed automatic transmission, which will benefit the Cadillac models using the engines in the fuel economy area, company sources said. In addition, the V-10s probably will be equipped with fuel-saving features, such as GM's displacement-on-demand system and/or variable valve actuation.

I'm assuming this won't be made in the new limited production engine facility here in Michigan (can't remember the name). This is great news for GM fans! Hmmm, an Escalade with a world class interior (2007 redesign), a 6-speed automatic, V10, and ground breaking exterior styling should do pretty damn well.

I would not want to see this new V10 go into the Corvette. I think the V8 is part of the Corvette Heritage.

I look forward to hearing the displacement and power output from this bad boy. If GM can get 450-500 HP out of a small block V8, imagine what they can get out of a big block (assuming it will be) V10!!

Assuming its based directly on the LS2, this would be a 7.5L, 500hp V-10....



I hope GM only puts this in Caddy, and maybe Hummer, fullsize trucks. But this would be a great tuner swap for GTOs and all the other Zeta's.....

I think a V-10 would help caddy w/ its image a lot (Not like it needs any more help caddy's doin great). I agree w/ giagastormer about a V-10 in a vette, that wouldn't be right. So I hope it stays in trucks like the article says. I would like them to stick it in the chevy silverado SS. I can see a cover of car and driver w/ the SRT-10 and the Silverado SS battling out for the best V-10 pickup.

Naaaaaah, this just a dream I'm having, GM with a V-10? I'm dreaming

[tgagneguam]

I wonder if that means model year 2007 or calender year 2007... not that I'm awaiting GM to offer a ridiculously powerful engine or anything. A few months sooner (model year 2007) makes a big difference for the impatient among us.

And I wonder to which General Motors crossover vehicle(s) the article is referring. A V-10-powered SRX-V? Nah, it couldn't be that good, could it? Does the Cayenne have reason to start sweating?

V-10 Solstice anyone?

[Smaart Aas Saabr]

It would likely be a 6.6 litre V10 making about 400 horsepower...

I still really, really, really want Cadillac to build the Sixteen...

Well, this is great news for GM trucks. When the new Silverados and Tahoes come out, and of course the new Escalade, this is VERY VERY good. While the 8.1 litre big block outpowers the V10s from Dodge and Ford (or at least did until a year or so ago), a new v10 is great marketing. That said, this better not go in any Caddy Cars. I want to see a northstar based V12 for those uplevel engines.

It will be in the Escalade, get used to it. :lol:

[desmo9]

I don't understand the hype over the V10. First Viper and Dodge trucks, now Ford trucks, then GM. It's a truck engine, and a crappy-sounding one at that. They can get all the power they need out of a V8, and if they need more image-factor, go to a high-revving V12 (which sound nice, like a V8).

[Nocturn_Bird]

I doubt GM will put it in the vette due to the added weight alone, there isn't anything they have to gain aside from copying the viper even more so.

I expect this to the a truck only engine, where in youll see the 12 in both perhaps. I want my XLRV....12

buwhah

My bad, usually when people say "cars" they mean vehicles in general.

That would be awesome if Cadillac were to put it in the DTS, there would probably be just a little bit of torque steer. :lol:

[GM_Guy81]

lol, yeah. Well, we can only hope by the time that 12 is ready, the DTS will have a whole new meaning! And by meaning, i mean RWD. Though, i think at that point it would probably be called the XTS.
