Default new STi is 3168lbs (according to Video)

I was watching the japanese VCD talking about the new WRX STi,

I'd be surprised if no-one caught this, but they quoted the weight of the new model as 1440 kg, that comes out to 3168 lbs

that leaves the only variable the weight of the 2.5 motor over the japanese 2.0...

if this is old news, I"m sorry, I've just seen a lot of questions asking what it was.

BTW, the DCCD controller is just a little thumb-wheel right by the driver-side door (for those who haven't seen it). they show it off in the VCD:-D

I'm drooling..:-P

That's the weight of the standard JDM STi. The American STi is reportedly going to be closer to the weight of the JDM STi type C, which is 1350kg, or even lighter.

Just curious why nobody seems to think the USDM STi won't suffer the same or similar weight gain as the USDM Evo when compared to their JDM counterparts. They have to meet the same regs, I don't know why they would be that much different.

Numbers from http://www.japanvehicles.com:

Evo 8 GSR: 1410 kg (3102 lbs)
WRX STi: 1440 kg (3168 lbs)
WRX STi Spec C 17" 1350 kg (2970 lbs)

The USDM Evo w/o sunroof weighs in at 3263 lbs, or 161 lbs more than JDM, and that is without the six speed and the trick diffs. I personally don't see the USDM STi being closer to the Spec C than the "normal" STi, but Paul generally seems to know what he's talking about, so I have included that as a lower limit:

USDM WRX STi: from 3131 lbs (2970+161) to 3329 lbs (3168+161).

Oops, I forgot, no radio on the USDM STi, better subtract 100 lbs!

jwtodd60,

There has been at least two threads in this forum alone on some speculation as to why the USDM STi may be close to Spec C weight.

Is weight within 100-200 lbs really a big deal here? Especially when factoring in the large american butts that will be seated in these vehicles. Now I can see if it had a composite space-age frame and weighed in at a mere 2200-2600 like some of the group B cars

Yes. The weight of a car has a negative effect on all performance aspects: acceleration, cornering, braking. Adding power to "fix" the acceleration part is relatively easy, but more weight will always hurt the cornering speed and handling. I agree that 100-200 lbs won't matter too much if you only use the car for daily driving. But if you run against the clock, it makes a difference.

If you had a choice of a 250hp STI that weighed 2500lb. or a 300hp STI that weighed 3000 lbs. I know which one I'd take---the 2500 pounder. It's just unbelievable what shedding weight can do to the overall handling, responsiveness and sheer enjoyment of a high performance car. Unfortunately we will likely never see such a car again. My old 911 weighs 2200lb(250hp) and is a fantastic track car. The newer 911s with 3.6 liters are faster, but not nearly as much fun to drive!

Oh yeah just wait for the new Audi S4 that is losing its 2.7L V6 TT and gaining a nice V8. More reliable horsepower with more sluggish weight. Should be a real party pooper.

no way that it will be lighter than a standard STI .. it might start life as a type c shell

but it will have and extra 100lbs of USDM bumpers alone

Actually the Audi V8 in the new S4 is the same weigth as the V6 TT in the previous S4..........it's the bigger body that porks it out.
I'm not sure if I would count the new S4 as an easy woopin'. It will be quick, but I feel the STI should still beat it.

I have some trouble believing the car will be under 3000 pounds

I tend to guess somewhere around 3100-3150 or so. I mean the car isn't that stripped

I'm just stating what was told to me by an individual that would know. All of the reasonings thus far tend to concentrate on performance. The information I received has everything to do with CAFE and very little else - STi is plenty happy with the performance of a 300/300 STi at 3200lbs - but they've got that one overriding reason to drop weight.

The Evo gained weight when it went to America because it was not originally designed to pass American safety standards. The STi is based on the WRX turbo - which was designed from the start to sell in the U.S. market. End Of Story. Despite fond wishing otherwise, the STi will be lighter than an Evo because of that fact, and is heavier than an Evo in Japan when you compare a JDM STi vs. a JDM Evo. However, the lightest STi and Evo are the same weight - 1320kg. Except that the STi RA keeps the DCCD and 6-speed at that weight, and the Evo 8 JDM uses a 5-speed at that weight, has a smaller gas tank, and I believe drops the AYC.

That means that the total base weight of a Type C STi starts at 2904lbs. 2970lbs if a kg is 2.25lbs (I've not found a clear answer if it's 2.2 or 2.25lbs). Add 66lbs for the 17" wheels/brembo brakes, and you are still looking at around 3050lbs. Now, start trying to really shed weight in any way possible...

Cheers,

Paul Hansen

1 pound equals .454 kg. Thus a spec C is 2974 pounds (rounded). I still think that a USDM STI needs a lot of tricks to come close to that weight. We know about some of them such as the composite intake manifold. But there got to be a lot more. Would be nice to know what Subaru is up to.

Yep, definitely a challenge.

Probably the biggest problem is the weight of the AC compressor and ducting.

To offset that, the US STi has the intake as Allegrita mentioned, DBW, and the standard manifold/uppipe/turbo (the twin-dump header and shields and twin-scroll turbo certainly look heavy)

Sheesh. SOA really needs to release some more information, we're in desperate need here!!!

Paul I see what you're saying, but the JDM Spec C doesn't have A/C which is a good 25-30 pounds conservatively and doesn't have a heavy front beam which is around 10 pounds... unless they're the same now? Also I don't believe it would have the side impact protection in the doors. It has crank up windows, stripped trunk, no melt sheets, no undercoating... I think all these things if true have to be around 35-40 kg or maybe a little less... and that would put us somewhere in the neighborhood of 3100-3150

It's okay, you'll probably be able to dump most of that with a decat, full Ti exhaust, race seats, and A/C removal...

As the Porsche boys are so fond of saying: lighter=faster. I'd like to believe Subaru can bring this car into the U.S. market at around 3000lb. That would be a huge achievement in todays market and regulations, especially for an all-wheel drive car. Neither BMW nor Porsche can do that anymore with their cars. It's pretty simple to bump up engine power these days, but darn hard to make a strong lightweight car, especially if you include most of the modern conveniences everyone seems to think are necessary.

the Spec C now has Front Airbags... or at least a driver's airbag. Not sure about side bags, which I think probably no.

Also Cruise is integrated into the Engine ECU (DBW) so there's no extra weight involved other than wire and the cruise switch on the steering wheel now.

soundproofing = melt sheets and undercoating and some fuzz under the carpet, what combination the Spec C uses I'm not sure but possibly just carpet. I know there's no asphalt and no sprayed undercoat. Our car probably has all of this.

The Spec C also may lose the HID as well to shed the weight of the ballasts off the nose of the car. But that's minor for such approximation. I'm sure SOA demanded that our STi have HID since it's a huge market feature in the US, if in fact the new headlights are available in a Halogen only spec.

The only thing that really weighs anything in the A/C system is the compressor and some of the bracketry. Since all the piping and condenser and evaporator are aluminum.

I really wish they'd bust out the aluminum bumper beams that are used by lots of other OEM's!
