Yes...you DO have to figure. Road surface, tires, air pressure, air temperature, density, humidity, wind direction and speed, weight in the vehicle, quality of the fuel used, how the transmission is shifted, engine break-in ..................ALL of these things have an effect on what acceleration times will be.

And...why worry about an 0.2 second difference? Who cares? That, IMO, is trivial.

 

Well-spoken.
The worship of HP and torque is one of the most inane things in the auto buisness.

 

And I blame the marketing of the auto industry for this because thats all they advertise.

Hp in this case doesn't matter much to me because I was happy with the power when I bought it. But dag nabbit tell me the truth about my car, and don't lie or give me a bunch of assumptions. I love my Lexus too but don't mislead me. Whether it matters or not it comes down to trust or a degree of trust. If a jewlery store sold me a neckless with 24k stamped on it it better be 24k don't come back and tell me its only 14k because they assumed it was 24k based on some scanty testing methods, or that my house I just bought is only 1700 sf and not the 2100 sf I thought I was buying, theres a SENSE of being cheated here because its not entirely what you thought you were paying for. Its the principle of the whole thing, so lets save the excuses for a more worthy cause.

 

What can I say? I told you so!

Toyota has gotten away with this to long. I bet you anything even now my sc300 still makes less then 200 hp. probably 195, (car is running awesome. clean tb etc etc.)

 

Another Detroit News winner. They have some of the worst articles ever. Toyota and Honda are some of the most honest companies, thus they changed the ratings right away. They DON"T NEED to sell their cars based on HP figures.
Many of the others do, b/c the rest of the car is lacking. And they will have to change EVENTUALLY.

 

I wish Nissan/Infiniti would rate ALL their models' hp under new SAE system right NOW like Toyota/Honda, I want to know what the G35 & 350Z hp rating would be . . .

 

Because knowing that will make your 2004 G35 Coupe go faster (or slower)!

Haha, just kidding.

BTW, torque also went up in the FX45, from 329 to 335.

 

Except there's one thing wrong here ... J1349 is not the NEW standard .... the Aug 2004 revision of J1349 was simply an update to close some loopholes. The new standard is J2723. To be fair, J2723 only differs from J1349 (rev 08/04) by third party witness and verification .... but that last bit is VERY important .... because without third party verification, manufacturers can still fudge their numbers.

As far as I know, only Toyota and GM so far have tested under J2723, which means their numbers have been verified by a third party.

Call me cynical, but I won't believe Nissan's ratings until I see them test under J2723.

 

Well, I'm always a little intriqued by the fact that the G35 with it's 55 hp & 56 lb-ft advantage over the previous BMW 330 & still didn't give it significant advantage in speed in the tests, I know part of it is due to gearing, but I also want to know if Infiniti really over-rated their hp . . .

 

Wrong. Only GM has thus far used J2723, third-party verification.

Toyota is incorporating the revised J1349 into most of their models, but has not yet used third-party verification.

" Pollak said he thinks most of automakers will use the new J1349 rating system. "That is the basic document . . . throughout the industry. It was developed by an industry consensus group."

However, it's less clear how many automakers will go for the third-party witness to certify that all the procedures were followed.

General Motors plans to use it as new or upgraded engines are introduced, Lancaster said. GM became the first automaker to have third-party certification of an engine with the 505-horsepower 7.0-liter LS7 used in the 2006 Corvette Z06.

A spokeswoman for Toyota said that most of its engines have already been retested using the new standard and that eventually all will be. But she said Toyota was still considering the third-party verification. "

 

Gearing and weight.

I wouldn't necessarily say that anyone "over-rated" their hp, just that Toyota, Honda and probably Nissan (and many others) took "full advantage" of the loopholes of the old J1349, while the domestics did not for the most part. And kudos to the domestics for that.

The Avalon's hp rating came down from 280 hp to 268 hp. I'm guessing that the 280 hp VQ comes down by about the same under the new J1349.

I'd like to see everyone (Nissan, Hyundai, MBW, VW, BMW, etc.) report under the revised J1349 starting from today, but it looks like most are going to update on a rolling basis.

 

At my track, I often get funny looks when people tell me my RX300 is 220 hp stock and when they see it is only a V6. At my altitude, 7,400 feet, you can imagine I lose a lot of hp.

Funny thing is that ALL of the SUVs I have raced against have lost, even ones with more powerful V8s (even when I tell them to run only a 1/4 tank of gas next time). Following all of my suggestions they still lose. I know some of these cars have more weight, but some of these cars like an Acura MDX losing to a little old slightly modified RX300? This happened just last week.

 

All this defending of Japanese auto companies is a bit laughable, because if Ford and GM were the only ones that had numbers too high you guys would be asking for people to be put in jail.

Wonder what my GS really had stock.

 

Enough people from the auto industry end up there as it is.


Mitsubishi is perhaps the prime example. The prosecutors really cleaned house there.
John DeLorean ALMOST went....he got off by a hair. Some upper-level people from Honda were also locked up recently.

 

Does anyone know if BMW is already using the new SAE measures for their 2006 cars? For example, the new E90? Would be interesting to see.
