GM Focusing on the V6 for 2011?

[Paulie]

Here's a report originally found on www.caradvice.com.au

A report from the US this afternoon says General Motors is close to completing a new, twin-turbocharged 3.0-litre V6 engine to combat Ford’s recently announced 3.5-litre EcoBoost unit, also twin-turbocharged.



According to a report from GM Inside News, several engineers at General Motors have confirmed the engine is in its later stages of development. The engine has been assigned the PRO code ‘LF3′ (GM’s naturally-aspirated 3.0-litre V6 has the PRO code ‘LF1′ – as pictured).

Although power and torque specifications have not yet been released, sources within the company say GM’s new twin-turbo V6 will produce similar figures to Ford’s 272kW offering – recently unveiled as the powerplant in Ford’s new Taurus-based Police Interceptor.

The report also said the new engine could find its way in to production cars as early as next year, possibly under the bonnet of the new Cadillac XTS.

Curiously, just today as well, Autoblog is reporting that for 2011 Chevrolet plans to one-up the new V6 Mustang again with a more powerful V6 for the Camaro. I wonder if they'll squeeze more out from the 3.6L atmo unit or if the Camaro will ditch the normally aspirated unit all together and go for a 3.0L turbo in the Camaro. Thoughts?

3.0L eh? I wonder what kind of power.

 

[YSSMAN]

Well, the thing is that the new 3.0L SDIC unit isn't exactly all that powerful, and its already being dropped for the 2011 LaCrosse. So, GM will probably dump money into the 3.0L unit, strapping it with two turbochargers, sticking the BHP rating somewhere around 350-355. I'd love to see a forced-induction version of the 3.6L, which has been talked about for a while,

Still, with the popularity of V8s in decline, and new platforms arriving that demand more from their smaller powertrains... Its a no-brainer to invest in your V6 technology.

 

[JCE]

So unless GM lightens their cars the 3.0L TT V6 cars will not compete with Ford what-so-ever. Odd, I guess they don't care?

 

[Paulie]

LOL wut? Have you.......have you checked the weight of a Taurus SHO lately? No I'm sorry, that post was a poor GM hate post.

I'm glad the domestic manufactures are finally realising they can get power out of a smaller engine. The new Mustang engine is pretty cool although it could be better for sure. I'll be curious to see what GM does, I just hope they don't half ass it like they do with a lot of their line. If GM could make a decent V6 and make it their staple (like the 350 was) then they would have a real winner on their hands.

You know one day V8's will be a thing of the pass or only available in very select cars, and I'm really OK with that.

 

[Jim Prower]

or available on really powerful cars. or are really small and rev so high your Mini'll sound far lower on the scale.

Newsflash, the Taurus SHO is not the only vehicle with that EcoBoost drivetrain. kthx

No, and practically everything else are even heavier SUVs and luxury sedans, where are you going with this? Other than the few ecoboost 4s going in to the Focus and Fiesta, but we're talking V6s here and those cars are therefore not part of the discussion.
I'm not saying the GM cars getting this engine are feather-weights, but you're making out like they're a heap heavier than the Fords, which is just a GM hate statement that I don't believe rings entirely true.

Does this mean the death of V8 Supercars in Australia? The Car of Tomorrow is announced Monday, so I suppose we will know then.

No, definitely not.

Final thoughts on this retarded new GM TT V6... Hello and welcome to 18 or so years ago.

3.0L V6's in twin turbo or N/A (Honda) from Japan over 15 years ago:
Nissan VG30DETT = 300bhp 286tq
Mitusbishi 6G72 = 320bhp 315tq
Toyota 2JZ-GTE = 320bhp 315tq
Honda C30A 270bhp 210tq <-- NO TURBOS EITHER!

Hate to burst your bubble, but a 2JZ is an INLINE 6, not a V6.

 

[JCE]

Yea yea yea, I know that. I added it in there because someone else would complain if I didn't. lol

 

[Rykon Zero]

If someone was going to complain about the Supra engine, they'd complain about the lack of RB26DETT too.

I'm not entirely sure what your point is. The current 3.0L mill that lasted all of two years already makes 255 BHP. The 3.6L DIG does the 300+ BHP dance. GM is looking to replace the 3.0L (apparently) with the rather-good 2.0L Turbo that had once seen duty in the Cobalt SS, good for 260 BHP. So, the new turbocharged 3.0L unit would, in theory, be good for somewhere in the neighborhood of 350+ BHP. Which of course would be, in theory, good to replace some of the small blocks in some of the vehicles.

But that's an inline 6 aswell, not a V6.

 

[Rykon Zero]

That's the point.

Yeah I'm confused too, this must have been some sort of effort to get me riled up, it failed. Clearly the new 3.0L turbo V6 by GM will be producing more power by the sound of it than all of them anyway, and also probably be more fuel efficient.

My only thing is how reliably they can do this. When I think of the Cobalt SS and cars like it (SRT Neon), reliability doesn't exactly come up as my first thought. Granted, direct injection and turbo charging have seemed to come a ways since my car and the Cobalt SS were developed, but it'll be interesting to see how these cars do.

I'm also guessing there will be more than a few owners messing things up and running regular gasoline in a car that needs premium. Who knows how well that'll play out in reliability surveys.

 

[YSSMAN]

I personally am not aware of a large number of issues with the LNF Turbo engine from the Cobalt, but there have been plenty of horror stories about the Neon. Given GM's work with turbos in Europe and Asia, with the expertise of Opel and Saab, chances are that they would have far fewer issues on average than most.
