View Full Version : Rumor: Next Gen Legacy STI 450hp Turbo 3.7L H6

When another batch of spy photos of the upcoming Subaru Exiga (http://www.autoblog.com/tag/SubaruExiga/) surfaced yesterday, we didn't give it much thought. We pretty much know the styling direction and dimensions of Subaru's new people mover, but one portion of AutoExpress' article caught our attention. In addition to the Exiga joining a new Legacy sedan and Outback wagon in 2009, Subaru's future drivetrain plans include dropping the 3.0-liter boxer and reworking the 2.0- and 2.5-liter engines to increase efficiency and power. The naturally aspirated 2.0-liter will supposedly produce 200 hp, while the current turbocharged 2.5-liter will exceed 300 hp. While neither of which is huge news, AE also mentions that a Legacy STI is on the way with a turbo'd 3.7-liter producing close to 450 hp. Whether or not such a beast will actually come about is open to debate, but when it does, we hope that Subaru has the foresight to make it available in the U.S.

I'm skeptical, but dear God, one can only hope! I don't think SOA has the balls personally, to let it happen here, if it happens at all.

1) It'll never come here, given SOA's long history of not giving us the good stuff.

2) It'll suck gas like a frat boy at a beer drinking contest.

NEVER going to happen and if it does it will cost over $50k! nobody gets 400+hp for cheap. so I don't see anything to be excited about.

wow damn this car would be a beast with 450 hp. I doubt this will come to the U.S.

U.S. doesnt get any of the goodies from subaru.

Well it could in theory be produced at their US plant, right? Thus it might make for a better business case. Who knows, they may even be able to produce it in the US and distribute it around the world. With the dollar going the way it is this could be a viable option.

What I find is really interesting is the info they have on the other engines. Those power bumps sound nice. Everything from subaru engine wise these days is pointing to direct injection which would be great.

And who cares if it sucks gas. The people who have this for their daily driver won't care.


I say bring it on, and that a business case could be made for this, even in limited production.... but only if it comes in WRB.


Oh and offer it with a DSG transmission to round things out.

I meant what I said, put it in the Tribeca!

However, this engine ill probably never come here anyway so its a moot point...

Even if it did exist, the timing is all wrong.

A better plan would be a 350hp (or even 300/300+) that got 30mpg.

The article also mentioned 300 hp for the turbo legacy. I wonder if there will be a weight bump with that.

As much fun as it would be to drive it's not worth what they'd probably charge on top of terrible MPG using premium fuel.

Correct, We will never see a 450hp Legacy STI in the US or Japan (from the factory)

I highly doubt there will be a 450hp Subaru anything in the US any time in the near future. A next-gen Tribeca high end model to battle the Cayenne Turbo S with this drivetrain would be awesome, maybe even smart.

I'll keep my fingers crossed for a 350hp Legacy STI, I'd settle for even 320hp. There's still plenty time for the last 2009 Legacy turbo to be a special "Tuned by STI" edition, that would rock.

On second thought, 300 hp and 450 tq would better right??

It would be interesting to see how much this would cost... The engineering challenges of creating a reliable transmission are huge. It would be nice to have one last guzzler before the fuel regulations set in.

It should be a diesel. Im just saying.

Right, just in time for $5 a gallon gas and CAFE averages of 35+mpg. A 3.3L 220-255hp H6 Turbo Diesel is about the best that could be hoped for.

Some of us might buy a $50k car...

Not much with 400 hp for that little $.

Subaru keeps disappointing... for their 50th anniv we were hoping some awesome STI, instead we got the wagon. We were hoping for a LGTSTI... which from the looks of things will NEVER show up here..

WAAAAAAAH !! I'm getting sick of waiting for suby to launch a m3/s4 competitor...

If they made a Diesel Tribeca starting at 260HP, I'd buy it in a heartbeat. Better low-end and much better fuel economy is pure juicy!

By the way, does anyone know if the new Subaru Diesel engine can use Bio-diesel as well?

file all this under not-bloody-likely. SOA doesnt have the track record to be taken seriously with a Legacy STI.

Put that in a wagon with a 6 speed, and I might be a little less sad about Audi never bringing the RS4 and RS6 Avant variants to the US, and I'd definitely buy one.

That said, a wagon Legacy STI is even more unlikely to happen than a Legacy STI in the first place, let alone it making 450 horses.

That will be the day. Might as well have Doc make a time machine out of it.

At first I thought 450 hp was a little over the top — that's about 350 whp in a car significantly lighter than an M5 or RS4. However, a sedan that runs low 12's would be a great halo car, with auto writers gushing about it smoking all competitors.

REX8
05-30-2008, 06:01 PM
If they gave us a 375 HP LGT STi Wagon for $40-45k, I think I'd bite.

For $50k, it had better be packing some more ponies though.

Remember, the upcoming Pontiac G8 GXP is under 40K, 402 hp/ ~400 ib-ft and hits 60 in 4.7. We can do better from Subaru. 450 would be a dream come true and I would seriously put a down payment as soon as I could.

Yeah, 100 hp and 100lbft more than an STI yet it's slower by .1.........

450hp in a Legacy is not happening, I could see low 300's though.

What's holding you back? You can get the real deal!

Getting the car back to the states, which is where my STi resides. I could go buy some mega sweet cars, but they'd never leave these shores, which makes it impractical to buy them. It's also annoying because see just how good Subaru can be, and then I know that I'm coming back to a half assed effort when I get home. If SOA had the intelligence of a 4 year kid with down syndrone they would stop dicking around and give America the same cars they give the rest of the world.

:confused:

You're smarter than that. I'd expect the AWD car to win that short sprint. That fact that it gets it, by only 60, is impressive.

you might be lucky to see it for 2 model years, after that the new CAFE standards will kill it.

Something to remember, this information is from Peter Lyon, which also figured the original BL/BP Legacy to have a 350hp EZ30 under the hood due to the dual rear mufflers. Not that I want to dash hopes and dreams, but his info is very speculative at best and usually assuming way too much.

A 450hp engine sounds cool and all, but it seems so much more like a pipe dream than anything else. It would have to have SI-drive, direct injection, and an onslaught of various systems to keep this car from being a gasoholic. Stuff I'm not sure Subaru is prepared to do. I do love it though when a higher power figure is mentioned, people assume the cost of said vehicle skyrockets. The real cost of the hardware isn't terribly more expensive in most cases, a few grand at best and most of that due to simply lower production volumes of a model type like this.

Don't get me wrong, its what I was waiting to buy when I was in the Subaru camp, and it could be truly an amazing machine that I would love to drive. But I'll just have to be part of the camp that will believe it when we see it. I stopped waiting for Subaru to build machines like this and just went with something that works well and can return respectable mileage.

Yes, but IF, they were able to pull it off, it would become that sought after halo car.

I agree, the new G8 is a steal but remember it is a domestic car, and domestics are always cheaper. Plus.. who wants a gas guzzling beast with gas prices at $4+ and rising??

I know I'm already having a hell of a time keeping my WRX filled up with premium and getting not-too-great mpg with all the city driving I do. Basically dashed my hopes of ever getting an STi anytime soon :(

PS Subaru should be focused on innovation: i.e., finding ways to make their 250hp+ engines get better mileage. Isn't there also a mandate getting ready to be passed within the next year or two requiring most new vehicles to get better than 30mpg? I thought I'd heard something to that effect.

SubieAutoXer
06-02-2008, 09:09 PM
direct injection and efficient dynamics/regenerative braking are two core technologies that will make an enormous difference in mileage on any motor, and are becoming more cost effective by the day.

Any motors Subaru is developing should include these by default. Their mileage will skyrocket.
