Default STi 0-60 time confirmed...4.8 sec.

Thanks to Jon CT for the link. I felt that it deserved its own thread since this is an important performance number.


Can read the link from here: http://www.subaru.ca/interface/Subar...Displayed+Desc
Paraphrased:

"Impreza WRX STi is powered by a turbocharged and intercooled 2.5-litre DOHC boxer engine producing 300 horsepower at 6,000 rpm and 300 lb-ft of torque at 4,000 rpm, and teamed exclusively with a 6-speed manual transmission. Power is transferred to all four wheels via a sophisticated Subaru All-Wheel Drive system designed to optimize performance in all conditions. This unique drivetrain also provides outstanding torque characteristics at both low and high rpm, taking the STi from 0-60 mph in 4.8 seconds."

The specs are exactly the same as the US STi. WEeeeee.
I can live with 4.8 sec

Please tell me if you think this is correct.

From a 2002 USDM WRX 5MT driver's perspective this is particularly impressive considering that there will be TWO shifts from 0 to 60.

I think that the numbers at the top of each gear will be really impressive.

anyone know what speeds the different gears redline at?

like a WRX: 30 - 60 - 90, etc...

Who thinks that the numbers they have i.e. 300 hp, 300ftp are not exact. Hopefully in the STI's case they will be even more. Just basing it off previous experiences with underrated chevy engines. Just 300/300 number seems too perfect. Anyway, just my thoughts...

If they managed the 0-60 the same way they managed the 0-60 in R&T for the EvoVIII that mean dropping the clutch near 6500RPM wich none of us would do. Let's wait for official tests with a "real life" condition 0-60.

That's what's so cool about that 4.8 number coming from Subaru. That IS "real life." Manufacturers are always conservative about numbers, Subaru particularly so. They say 6.2 for the WRX, which is what you get when you drive it normally, no launch.

Uh, that's one fast ride. Figure 4.5 or so with a launch. Wow!

gtguy and all of you: Let's wait for testing from some magazines and by some people...

I had a 02 Z06 and Chevy claim 3.85 0-60... Conservative? Not really... They were conservative on the Camaro SS HP and Firebird Ram Air HP but they were not conservative on the 3.85s for the Vette Just find me one person bone stock who managed that 0-60 on the Z06 Vette. I've managed 4.2 (wich is quick compared to a lot of people but it's almost half a second slower than what Chevy claim) and 12.46s 1/4mile.

Just my 2cents but until it's been fully independently tested, I won't take any numbers as "official" for 0-60, 1/4 time.

11.8 secs has been done in the 1/4. I was at track when a guy ran 12.02 then followed it with a 11.9. Yep, bone stock, tires and all, full interior just like he bought it and regular old 93 octane pump gas. I would say that he managed the 3.8sec 0-60. Good driver though. CHRIS RAMEY is the name. I believe he got 3rd nationally in SCCA auto-x. Watching him drive is like

Chevy's optimism aside, Subaru is known for claiming more conservative figures. And, the 4.8 is consistent with UK STis with the PPP, they see 4.6 0-60 with what will almost certainly be a heavier car.

Besides, Subaru has nothing to gain by inflating the times, every magazine and test group will be reporting what they get soon enough...better to have those times be faster.

I would believe that it would be a little bit quicker in that M2 WRX in C and D got 4.4 in 0-60 with 320 hp and 305 lb-ft while weighing 3199 lbs.

Yes, of course the good part about this is that it came from Subaru who is usually rather onservative on their performacne times.

However, I must agree to in that I won't get the real answer until Autoweek, R&T, and Motor Trend do their road tests. (I'm partial to R&T) Remember the differences MT had with R&D with the USA WRX..(i may be wrong here) one mag had 0-60 in 5.6----the other mag was like 6.2. That's a big difference in my book.
I suppose whoever has the hardest launch....which I'll never do in my STi.

IMHO 0-60 in 4.8 sounds very realistic for the USA STi, given the power and weight. Will we see faster?? probably. Slower? probably. For me, I'll average them (mag road tests) together to get an overal feeling....

Oh wait....of course I would rather know how it handles on the skidpad and salom! (add gravel in there for fun

With redline @ 7000 rpm (taken from posts here)

Gear ratios from here:

Works out to:

1st: 36.7 mph
2nd: 56.2 mph
3rd: 75.7 mph
4th: 99.1 mph
5th: 137.3 mph
6th: 176.4 mph

What's odd is I thought most companies gear for 100 kph (62 mph) in 2nd gear at redline in order to get the best 0-60 mph / 0-100 kph times by saving a gear shift.

So is the redline incorrect? It needs to be ~7700 rpm for 2nd @ 62 mph.

Bang...you got me Jon. I suppose I was guessing the weight of the car to be around 3200 pounds; on the safe side. Rough calculation makes me feel that 0-60 in 4.8 is realistic. (although I do not dump clutches at 6000 rpm to get fast times)

However, like I mentioned above, I'll wait till the major car mags do some real road test on the STi.

I'm very curious about the US STi skidpad numbers. The US EVO had something like a .97...which I thought was extremely good for a middleweight AWD car. Will the STi be just as good? Does the DCCD come into play for this?? Predictions?

Default .97... all tire

Skidpad is more a test of tire grip than the car itself... yeah the evo has pretty good dynamics... but the yoks are doing all the work there.

The yokahama tires on the new evo are amazingly sticky. They rate up there with the old Kumho Victroracers in terms of grip. Its the one ace Mitsi thought they had during testing for the evo... real world driving will get less than 10k miles out of those tires... I can't imaging what a few autocrosses will get out of them. Replacement costs are high for those as well.

I'm eager to see what the RE070s can do. With such a rare tire I'm worried about replacement costs same as the yokahamas on the evo, but since I usual have three sets of wheels and tires for my cars anyways (superlights and hoosiers for autox, some kind of nice summer tire and nice wheels for summer and blizzaks and craptastics for winter) I'm not too worried about trying to keep RE070s on the STi all the time.

I think Skidpad is going to be good the STi... well above the .90 mark I'm sure thanks to the tires.

Most companies do gear their cars that way, thank god Subaru doesn't. A transmission should be geared around the engine's powerband, not the quickest 0-60 time. If you've ever driven an old 6-speed Toyota Celica with an overly tall 2nd gear you know what a poor design decision aiming for the quickest 0-60 is...

Thanks for converting the gear speeds, the ratios look good, except maybe that 5th and 6th could be a little closer to 4th With the realities of acheiving modest fuel economy though those numbers look good. Time to take out a student loan and trade in the WRX for an STi

Definitely two shifts to 60 and 4 in the quarter mile! In-gear acceleration in 1st-4th should be eye-poping.

Looks to be very flexible for tight tracks, mountain twisties and autocross.

Well lookee here! Compare these stats against what I computed from here
http://forums.nasioc.com/forums/show...hreadid=181343
and here
http://www.sgmotorsports.com/mph.htm

JDM STi V5 / STi V6
First Gear 3.166 (3.083 Type R/RA) 42MPH @ 8000RPM 31MPH @ 6000RPM
Second Gear 1.882 (2.062 Type R/RA) 63MPH @ 8000RPM 47MPH @ 6000RPM
Third Gear 1.296 (1.545 Type R/RA) 83MPH @ 8000RPM 63MPH @ 6000RPM
Fourth Gear 0.972 (1.151 Type R/RA) 112MPH @ 8000RPM 84MPH @ 6000RPM
Fifth Gear 0.738 (0.825 Type R/RA) 156MPH @ 8000RPM 117MPH @ 6000RPM
Reverse Gear 3.333
Final Drive 4.444
70 MPH @ 3700 RPM in top gear (eye balled)

to the stats above.

Do some math and you'll see that that the gear ratios are just about identical between 1-5 inclusive. I chose 8K RPM as a comparison base.

Maybe what happened was the engineers thought that mimicing Type old school RA gearing would be a great start to an rapidly accelerating car. The old car however had a 8250RPM redline so was capable of slightly higher speeds at redline. (~65MPH in 2nd @ 8250)

What's redline on the NADM STi anyway? I believe there was some early confusion as to whether it was 7K or 8K based upon a picture that was blurred to simulate motion. If it's 8K then it'll hit 60MPH in 2nd just fine so only one shift is required.

I'm glad Subaru decided to give it short gearing. That coupled with the VVT technology will give this car some good rolling start potential.

The stat that means SOOOOOO much to me personally is the 5-60MPH Street Start. No launch means it's almost a first and second gearing rollon test. A total unison of low speed gearing/power/traction is required here and I believe the NADM STi has it in spades.

The question that is in my head is whether or not this tested STi's weight is representative of production models... that's what I'm wondering. Testing methodology plays a big part too... don't want to find out later that it was done one time down a slight incline with a 30MPH tailwind.

I know that this was stated by the specs so far, but I don't believe that it is right. They had the same number and coloration on the tacho for the US EVO and it ended up being at the 7500 RPMs. My believes are that we have the same situation here, as well!
