What is Aston Martin up to? - Page 155

tje23 · 21 Feb 2012, 17:51 (Ref:3029016)

I was at Silverstone for the ILMC/LMS this year, the GTE/GT2 spec Vantage sounded amazing, and that's only a V8! The new GTE car is being tested today again, ahead of the launch on Friday - so we should hopefully get some decent photos/videos soon!

Pandamasque · 21 Feb 2012, 21:28 (Ref:3029142)

Interesting that they chose to stick with cross-plane crank V8 for this time (so far?) after troubles with the new engine in the first half of 2011.

I wish they'd use a downsized V12 for GTE though! If Corvette could sleeve or destroke their 7.0l V8 to 5.5l, then surely getting 12 cylinders from 5.93 down to 5.5 shouldn't be a problem, right? Or is it about the weight?

JayBMS · 21 Feb 2012, 21:43 (Ref:3029148)

Weight, size and marketing.

the 5.5 of corvette is a total new built racing engine by GM with just basic structure shared with LS stock series, it's not a 7.0 destroked! the engine used in 2009 was the katech LS7R destroked.
Talking about "destroking" corvette (GM) could be able to do a thing like that because of their know how, but AMR/Prodrive isn't the best company if we talk about engine, so if they'll be able to set an engine a bit more reliable and powerfull than last year will be already a great result.

I agree totally

Reliability isn't what that V8 is know for, the V12 however...
And I'm sure I've read somewhere, quite possibly here, that the new so called LS9.R engine is heavily based on the 7-liter GT1 engine rather than the ZR1 unit.

alexkiller8 · 21 Feb 2012, 22:10 (Ref:3029166)

the ls9.R like the name tells, is based on the ls9 (both ls9 and ls7 shares small block LS basic structure) and is not the engine that is used on the corvette gte, isn't a racing engine at all. More info here

Yet another reason for AMR to stick with the V8, not a V12 unit.

FstrthnU · 21 Feb 2012, 23:12 (Ref:3029194)

Do we have any idea what's the roadmap for the Vantage road car's replacement? Maybe AMR figures that the lukewarm reception of the Vantage V12 combined with a possible(?) car replacement in the near-future mean it's not worth their while to stick the V12 into the GTE.

Not only would it cost money to adapt the V12 for the GTE, it would raise the overall price of the car if a customer wanted one for whatever reason.

Before I forget, the 2009 GT2 engine wasn't a Katech engine at all, it was the first engine for the race program from GM themselves.

No, it was a destroked LS7.R GT1 motor.

MitchZ06 · 22 Feb 2012, 09:51 (Ref:3029335)

I can't find the link to backup what I've said so we'll have to agree to disagree.

I see a Pro GTE Vantage is on the Sebring entrylist which will be interesting to see how it gets on during the race.

"In the remaining races in 2009, the Corvette race cars will be powered by 6.0-liter GM small-block V8s that are based on the 7.0-liter LS7.R that powered the GT1 version."

"2009: 6.0-liter LS7.R"

MitchZ06 · 22 Feb 2012, 10:00 (Ref:3029341)

Fair enough, I'll take the official line.

Tim the Grey · 22 Feb 2012, 10:06 (Ref:3029345)

I did see an AML future model plan, in something like Autocar, about 4 months back. I cannot remember ANYTHING from it, sorry. Perhaps someone could find it?
It discussed platforms, and engines, and future technology...

if i heard well, he says that the engine is an evolution of their production engine roads, well this is not a revelation after all

as i said gte engine share basic structure with road engines (the v8 16valves small block with alluminium heads structure in this case) but are heavily modified to become almost a brand new engine in their function, i can give you some examples. The f142 engine of 458GT share basic structure with the road one but road one has 540Nm of torque around 7000rpm and 570hp at 9000rpm, the racing version has a so different set-up that makes it work like an american style v8 low rev engine (around 520Nm around 5000rpm and max power around 6250). The 5.5 engine of the corvette even if has been projected and built by GM, share a lot of know how from katech LS7R (revlimit that doesn't pass 6000rpm and a insane amount of torque around 740Nm). However trust, the 2009 engine was the LS7R destroked.

This is the AMR thread, isn't it? Isn't the GTE Vantage introduction soon?

Yes, it's launched officially on Friday, however a few pictures have been 'leaked' by the Team testing the GT3 Vantage with AMR. (https://twitter.com/#!/BeechdeanAH/s...540224/photo/1)

The new-spec GTE Vantage V8 is competing a full 2012 WEC calendar with 1 GTE-Pro entry, and another GTE-Am entry at Le Mans - they also have another GTE-Pro reserve entry for La Sarthe. The first race the car will complete, or at least attempt to, is the Sebring 12 Hours. If you want to know more, check out Darren turner on FB/Twitter, as he was testing it the other day.

TF110 · 23 Feb 2012, 10:04 (Ref:3029790)

Thanks, I know all that. Really I was just trying to steer the thread back to AMR instead of the Vette engine discussion.

ooh, that's nice looking. Damn you ACO, why couldn't we have another of these at LM......

Can someone post the picture here, I don't have a facebook (Nor want one).
