Holden Twin Turbo V6

Mr G8 · 19-03-2013, 11:02 PM

This could be Holden's answer to Ford's potent Falcon XR6 Turbo.

General Motors has shown off a twin-turbocharged engine based on the 3.6-litre V6 used in the Holden VF Commodore.

The new motor makes a V8-beating 313kW and 583Nm, 43kW and 53Nm more than the current 6.0-litre V8 in the SS and will be linked to an eight-speed paddle-shift automatic transmission in Cadillac’s new CTS sedan.

Cadillac says the engine “brings a new dimension of technologically advanced performance “ to the brand and develops 90 per cent, or about 520Nm, of its torque from only 2000rpm.

The engine would give Holden an answer to Ford's popular turbocharged XR6, as it is based on the engine used in the Commodore SV6.

But the twin-turbocharged unit has several key departures from the Commodore engine, including new cylinder block and head castings and strengthened internals.

The brand’s director of external communications, Craig Cheetham, poured cold water on the idea of a twin-turbo Commodore in the short term.

“There are no firm plans to introduce it to Holden,” he says.

“Not in the near future... not at all.”

The new VF Commodore SS is expected to retain Holden’s current V8 engine, which puts out 260kW as an auto and 270kW as a manual.

GM’s local arm has previously flirted with turbocharging for the Commodore, in the form of a $3.5 million concept car shown in 2005.

The hot pink Torana TT36 concept car had a similarly twin-turbocharged version of the Commodore V6 which pushed out 280kW and 480Nm of grunt.

The Holden engine plant in Port Melbourne also built turbocharged six-cylinder engines for Saab before the Swedish marque collapsed in 2012.

I like the Caddy symbol on it haha. Still only 3kw more than the F6 single turbo.....

True, but it's also ~20Nm up and it does that with 400cc lower displacement.

That's true, but see what happens if Ford "bolts" another turbo on the F6. Will give it a hell of a lot more than GM has

Not sure...another turbo would only really be handy for beefing up low end boost, coupled with a larger one for more top end, but packaging would be a nightmare, and in the end, the gains would not be really worth the effort.

Now, a twin-scroll setup would be awesome to see...

I sometimes work in the turbo sub assembly area where the turbo, piping and all the oil and coolant lines get fitted up after the base engine is hot tested, and it's fairly complicated fitting one turbo, let alone two. Now that would be a nightmare.

Mr G8 · 19-03-2013, 11:08 PM

Haha yeah, its still not (IMO) going to get a much rep and fame as the I6T. Ford FTW

jpd80 · 20-03-2013, 12:11 AM

This is a premium engine supplied to Cadillac with an Aisin 8-speed Auto, so don't expect to se an SV6 Turbo anytime soon...

But would HSV consider the TTV6 as a new exclusive addition to the range?

FPV GTHO · 20-03-2013, 01:50 AM

I dont see them going for it personally. If they already have to pay more for the standard V6 than the V8, the TTV6 will be more again and theyre likely to still sell it cheaper than a similarly powered V8 which for this is still likely to be entry level HSV for the next few years.

FalconXV · 20-03-2013, 04:33 AM

Can't see it going in Commodore any time soon.
Even if it did, 11 years after Ford did it with a far better six- Congratulations Holden; you are officially smarter than a carrot.

MethodX · 20-03-2013, 04:50 AM

Good to see GM making this.
Why compare this to the Ford motor anyway?

jpd80 · 20-03-2013, 03:10 PM

I-6 Turbo and S/C 5.0 V8 are both available here and now to buyers.
Holden is yet to match either of those engines.....

Exactly, it is a motor of similar cylinder count with forced induction that may see a car here in OZ.
Whether it happens or not though, who knows.

A good mate of mine that I went to school with (many years ago ha) has worked at GMH for over 30yrs, mostly in engine development. When I bought the BA XR6T in 2002 he was 1 of the 1st that I took for a spin.. Anyhow he was telling me that his dept at GM were working on a TT V6 and had got some pretty impressive numbers out of it. And that the yanks had been over for the testing and were keen as for over there. This was over TEN years ago is my point! He also believed Ford had trumped them with their inline 6 being heaps more turbo friendly, hugely understressed as a relatively stock Falcon6 and so much cheaper to do than their V6 which was expensive and at it's absolute limit without major internal redesign. We'd also be pretty silly to think Holden hasn't done their sums on Turbo technology with the impact Ford had with the XR6T.

VL turbo was how many years before ford?

You mean the Nissan designed and built engine?

Nissan engine yes, developed with a turbo and software by holden.
Nissan don't make an RB30 turbo.

Nissan designed and built the engine for Holden, after Holden asked for it

And yes, Nissan never offered the engine in anything else.

Ibanezteve · 20-03-2013, 05:12 AM

Sv6-TT, Or an HSV R6-TT, Could be a very interesting prospect?? I reckon it could have Ford a little worried?

Nikked · 20-03-2013, 07:28 AM

Lol @ thread title...

If the VF was getting it, there would have been hints of a development program in the works over the past 2 years.

Interest in the "million dollar Monaro" has wained, so they need a new story for the week.

What next?

XplosiveR6 · 20-03-2013, 07:41 AM

So Holden say their have no plans at all to use this motor, but they still persist with publishing the article with no substance at all... Journalism at its finest...

**Burnout** · 20-03-2013, 07:46 AM

Ho, Hum.......

pursuit2359 · 20-03-2013, 01:05 PM

I agree that the odds of this engine in the VF Commodore are incredibly remote. I've noticed a few stories from Drive recently where the headline is nothing more than click bait since there's no substance to the story itself.

Here's another example: Is this the next WRX? (No, it's the VIZIV concept which is completely unrelated to the next WRX)

Mighty Reds · 20-03-2013, 01:25 PM

Drivel seems appropriate for the quality of articles they produce.

Mr G8 · 20-03-2013, 02:12 PM

They really are "scraping the bottom of the barrel" on these stories

pcman · 20-03-2013, 02:24 PM

im gonna stockup on caddilac badges to sell to all the commodore owners that dont wanna drive a holden

We don't know the real outputs of the F6 engine though, and who's to say the GM engine isn't underrated either

Well traditionally when ever tested in the real world and not "media evaulation units" Ford engines always seem to read above what they should whilst Holdens tend to read below.

There are quite a number of documented cases where Holden and HSV have been caught out tickling up the test cars before comparisons.
