Asians overrating horsepower?! Interesting article......

http://www.detnews.com/2005/autosins...A01-283759.htm

Looks like some of the MZ3s competitiors have been downrated. The 2.4 motor in the Toyota Camry (which is the same motor the tC uses) went from 160 to 154, and the standard RSXs 2.0 has been downrated from 160 to 155. Doesn't look like Mazda got caught fiddling with their hp numbers this time!

I personally don't see the big deal. Most adjustments were in the 5-10 hp range, and every engine produces different numbers, even two similar engines built side by side. And like others have said, the vehicles are not any slower just because somebody changed a number on paper.

There's no reward for failure..........but death!

Re: Asians overrating horsepower?! Interesting article......

If you're comparing a 210 HP Camry vs a 210 HP Mazda6, and the Camry is suddenly 190 - that's a big difference, from an advertising perspective.

The car may not perform any differently, but I wouldn't even look at a sub-200 HP V6 to find that out.


It's important to note that Ford has not retested any of their old cars, and I'm pretty sure Mazda's following their lead.

But yeah, I posted this here yesterday:

Never knew that Mazdaspeeders board even existed, no wonder I didn't see it there!

Honestly though, the type of people that buy Camrys, Accords, and the like really don't make that big a deal of hp figures, after all, those are mostly "family cars".* Those that shop for cars like the Mustang, Charger, etc. would be the ones affected by this snafu.

It seems the domestic models, and GM more specifically, have been underrating their engines hp figures for at least the past 5 years.* Another example is the Saturn Ion/Chevy Cobalt supercharged models.* These are rated at 205hp by GM, but many owners have dyno sheets that show anywhere from 205-220 hp at the wheels!

The diff mfgs were not overestimating their hp numbers. It was just different interpritations on how to perform the old hp test led to different results... New test is stricter with less wiggle room to level the playing field... Some mfg will benifit...others will have to adjust....

Also note most mfg will not retest existing power polants but will wait till a redesign to perform testing....

True, and almost no manufacturer besides GM will certify the results. If they certify then every powerplant will need to produce power to within 1% (or something like that).* This new standard won't help or hurt. It will produce a baseline that will fit the global market. We shouldn't have to worry about SAE verses Metric numbers for power and torque. Everyone [should] conform to the same standard.

Hopfully they also follow GMs lead and certify that all of the engines in the line meet the stated output to within a percent or so. That way, when the book says 250HP you won't be surprised if you bench test your bear motor and it's 238HP (as in the case with the RX8).
