Yeah, that's about right.

Post 275 ft*lb!!! (new STi tech data)


Data on the new STi's from Subaru's official page:

All models - 275 ft*lb of torque max at 4400rpm
- signature Subaru torque curve -- power on at 3000rpm, flat all the way through to 5500rpm!
- forged pistons and conrods
- "semi closed deck engine", whatever the heck that means
- larger intercooler with water spray as standard

STi RA = 3087 lb (17" version)
STi Sedan and Wagon = 3153 lb (how can this be? hmmm)

(overall torque/weight ratio -- 8.9 ft versus 9.0 ft for the previous version -- bummer)

STi RA available in 16" and 17" versions -- 17" has "sport tuned" ABS and BIG brakes. 16" is 44lb lighter.

Roof vents standard on RA only. White paint only as before.

Trannies. As you know all STi's have the 6-speed. There is an adjustable shift light feature built into the stock cluster (2000-8000rpm in 100rpm increments) for all you drag racers. And yes, folks, the gears have been beefed up. Note that 6th gear is pretty much identical to 5th gear in the normal version -- therefore, probably VERY buzzy at stateside freeway speeds. Better to wait for an Aussie or UK STi version with a taller 6th gear.

Front skidplate fitted as standard.

Steering ratio 15:1 on all except RA, which gets the same 13:1 quick ratio as before.

Whoo-wee.

The STi RA was like 2650-2700lb, the regular WRX was 2750-2800lb.

The STi5 and 6 made 260lb-ft. No idea if it was over as broad of a rpm range, but IMO if that weight is right there is no way the car will perform as well as it previously did.

this extra fat is the price we pay for a stiffer chassis, which in the end, will hopefully improve the car overall. if it superfluous crap, i'm sure we can pull it out. I'm still hunting for various pieces of insulation lying around that I can take out, like the one between the rear seat and trunk. Hey, hopefully it'll add up in the end, ya know? still cheaper than buying a CF hood.

Don

P.S. No, I do'nt have a fat A$$, so I can't really lose weight there.

yea, guess 15 lbs more torque with a flatter curve aint gonna make up for 300 more lbs of dead wieght
so what it boils down to is that they ruined its looks and its preformance
they're a bunch of geniuses up there arent they

Yeah, that's about right.

Overall I would expect the new STi's to be about as fast as the old ones, based on the torque/weight ratio I posted above. Ironically the thing that would probably slow em down the most in the 1/4 mile would be the 6-speed tranny.

My guess is that the six speed is there simply to achieve feature parity with lesser cars that don't enjoy a flat torque curve (Honda, Toyota). Again, the tallest gear is unchanged, so high speed cruising is not going to be improved. Then again, take an STi RA, tune it for max hp in a narrow range, and suddenly the six-speed looks like a good idea after all...

Here ya go folks, the sweeeeetest torque curve among turbo 4wd sports cars, bar none.

<IMG SRC=http://www.subaru.co.jp/impreza/sti/technology/img/grfu.gif>


Blue line is the previous model STi. Red line is the new one. Note overall hp has remained the same (yah right). Also note that the "bump" at 3000rpm has been smoothed out somewhat -- as CAR magazine noted in its test drive.

From what Prodrive said, most of the added weight to the new Impreza is as a result of the more refined interior. They said the shell is almost the same weight as the old one. Sooo.... Out goes the interior, down goes the weight...
