2006 Corolla and Matrix

[alphasubzero949]

1ZZ: 126 bhp/122 lb-ft torque
2ZZ: 164 bhp/125 lb-ft torque

:laugh:

The pussification of the Toyota lineup continues.

On the bright side, the XRS models do get new struts, sway bars, springs, and a STB. :rolleyes:

suxours

[Pinchy]

is it bhp ?? or whp ???

if its bhp, why are they lowering the 2ZZ??

is it too fast for the car???? :gay: :lame:

[combatc87]

Ugh... that's just not cool.

[slidr]

Huh, I wonder what they did to them. Just tune them down a little via the ECU?

Do the XRS models only come in 6 speeds?

[jetboy]

The stock clutch cant handle the power and weight so they are lowering the power instead of adding a better clutch. OK, only speculation, but the XRS clutch sucks for certain.

they come in auto also.. friend has on.. lift isnt quite as powerful as a gts auto

[slvceli]

Could the rest of the horsepower and torque curve below peak be better?

[slidr]

they come in auto also.. friend has on.. lift isnt quite as powerful as a gts auto
That's what I thought also, but on Toyota's website, they say the 5 speed and 4 speed auto are N/A and the 6 speed is standard.


Same thing when I try and build my own Matrix.

Perhaps a change to the newer models or am I missing something?

[RookieGTS]

I think thats pretty gay

This is why I'm no longer going to buy Toyota... And I know I have a GT, but it is the idea of diminishing returns... I might have bought a new Rolla or Matrix XRS, if they had the 2003's 180hp.....

[Bi-Mon-Sci-Fi-Con]

Before everyone starts bashing Toyota, are these figures using the old SAE method of hp/tq calculation or the new standard? The new method tends to give lower ratings than before.. I know Acura is using the new standard for the 06 model line
"For the 2006 model year, all Acura horsepower and torque specifications have been updated to reflect revised Society of Automotive Engineers (SAE) J1349 (Rev 8/04) net calculations that went into effect in January of 2005. These new calculations reflect a number of significant changes in the way horsepower and torque are measured and may cause SAE net horsepower and torque totals published in 2006 media materials to differ from the figures published in previous years. To avoid confusion, all 2006 Acura press materials will specify

Only the 2003 models offered A/T for the XRS.

[BaLLnFoShO]

:rofl: to bad for the people that get those cars..

[Another_Ricer]

peak TQ @ 4400...better for daily driving, but will suck up top... now why the h-ell did toyota decreased the 2zz's power.. damn toyota.. my next car will not be a toyota. All the affordable toyota sports compact will be too slow.....As for Acura/Honda for example, just keeps going up... ahem.... 2005 RSX-S..

[Another_Ricer]

seems to me like a GSR might be able to beat the corolla XRS since the hp/Tq is lowered... :(

[alphasubzero949]

Don't forget that TRD practically gave the middle finger to the '05 Corolla/Matrix 1ZZ owners who want either a S/C or CAI.

So far no one has stepped up to get a CARB-approved intake or FI working (in part due to the DBW/ETC system).

[JCturbo]

Those are the new SAE power ratings, new standardized testing for all manufacturers. the XRS models are still at 170hp, but the new testing forces them to use the same grades of gasoline, and have all emmisions equipment in place for testing. you'll note every vehicles ratings are down, the RSX-S went back down from 215 to 205

If an AUTO GTS runs 17's can you imagine an Auto Matrix?

GSR is a bit faster than a Corolla XRS as it is.

[Automaton]

Here. Read it... Love it... It's already been mentioned 2 other times in this thread, so quit making coments about how "Toyota made the engines less powerful."

Cliff notes: Testing is now done more according to real world conditions, not with a stripped down engine in 100% ideal testing conditions. There is also a 3rd party witness that must be present to "certify" the test results, but that part is voluntary. The new Z06 vette was the first to undergo the new certification process.


Engine-Rating Rip-Up

By Bill Visnic
Ward's Auto World, May 1, 2005

The Society of Automotive Engineers announces at its annual World Congress last month significant new updates to improve the accuracy of the test standard auto makers have used for more than 30 years to rate the power and torque of light-vehicle engines in North America.

Equally important, the SAE also is introducing an all-new, voluntary test procedure designed to ensure power figures derived from the new standard are more reliable and common across the industry.

David Lancaster, General Motors Corp. technical fellow-GM Powertrain, and chairman of the SAE committee responsible for revising the standards, says engines tested under the new 2-stage system will list horsepower and torque figures with a new qualifier: SAE “Certified.”

Since 1971, engine horsepower ratings have been published by auto makers as “SAE net.” Lancaster says the “old” SAE standard that set forth the procedures for measuring horsepower — J1349 — has been updated to “remove ambiguity” in its language that left certain loopholes that could be exploited to exaggerate engine power.

In some past cases, manufacturers have taken advantage of J1349's loopholes to generate horsepower ratings that could be achieved under the rarefied conditions of an ideal testing environment — but were unlikely to be replicated in the real world.

Last August, the SAE finalized an updated version of J1349 that more precisely defines certain engine-operation parameters used when testing an engine to rate its horsepower and torque.

These stricter definitions, Lancaster says, close J1349's loopholes and ensure “a realistic condition the customer will actually see in the vehicle.”

In concert with the updates to the J1349 engine-testing standard comes an important new component: a voluntary test procedure — witnessed by an independent third party — that must be undertaken to earn the new “Certified” rating. The voluntary certification test — SAE standard J2723 — was finalized March 31.

GM says it has the world's first production engine to bear the SAE “Certified” label for its horsepower and torque figures: the all-new LS7, a 7L OHV V-8 that powers the ultra-high-performance Corvette Z06 coming later this year.

It is unclear, however, how many manufacturers will perform the voluntary new J2723 certification test, or if they do, what strategy will apply for selecting which engines in an auto maker's existing powertrain portfolio will be selected to undergo the certification process.

GM, for one, is intensely committed.

“Within a couple of years, the vast majority of our engines will be SAE certified,” says Lancaster.

Ford Motor Co. participated in the committee that updated the J1349 standard, and Frank Sadni, Ford director of V-engine engineering, and Jerry Beamer, Ford engine performance development manager, say Ford is testing a variety of '06 model engines in compliance with the new J1349 standard, but currently has no plans to put engines through the voluntary J2723 certification test. Ford, Beamer says, “is confident that our (internal) process for rating engines is very robust,” and sees no need to have horsepower and torque figures verified by a third party.

Rating engines with the newly revised J1349 could cut at least a few horsepower from an engine's current rating. The new J1349 standard “says you have to (test the engine with) the same hardware that's in the vehicle,” says Lancaster. That means, among other things, the hydraulic power steering pump now must be attached to the test engine — usually at the cost of a couple horsepower.

For that reason, most auto makers are likely to continue to publish ratings for existing engines derived via the “old” J1349 standard whenever practicable.

“When J1349 was originally written, we were running with carburetors and (mechanical) distributors,” says Lancaster. And, he adds, “the standard never said the intent (of J1349) was to give a customer a representative number. Having good, solid (engine power and torque) numbers provides a lot of benefit to us in the industry.”
