What difference does it make?
They could call it 200 hp in the SAE system and
as long as EVERY other car conforms to the same system
it's all relative.
Personally, I'd like to see SAE start requiring the horsepower and
torque figures to be TO THE WHEELS!!!
This way, when a company is testing a new engine or new car,
they are required to provide at least 5 of these cars and
the "ratings" is the average of the 5.
And then, as soon as they go into production they are required to
test another 10 cars and these production models have to within
the average of the 10 preproduction cars to keep the same rating.
And if changes are made to an engine, where a company wants to
rerate the engine, they have to provide at least 5 more cars for
testing to see what the new "average" power ratings to the wheels
are before they can claim the power increase.
On a side note...the new IS350 with it's 306 hp rating IS with the new SAE
standards!!! With the "old" standard the engine would of been rated at least
315 hp. Out of a naturally aspirated 3.5 V6...wow

I don't mind the new system, if it creates a more uniform way of testing cars and more truthful HP advertising.
The TL guys already have a 20 page thread from when the TL's numbers were lowered to 258 under the new system.
I don't think we'll ever see manufacturers advertise at the wheel HP. It'd be too easy to show that your car doesn't make the advertised power = more class action suits. With the current system, consumers realistically aren't going to pull their engines from the cars just to measure crank HP, so they can't really prove that the engine makes XXX HP.

Interesting... I ask what the sae torque number is and I get what difference does it make...yadda yadda yadda. I am curious how the new rating system impacts the old rating is all. If you do not know say you do not know... I do not need some advice on what to think... I know all about HP and ratings and torque. Hell I had a boat that had 205 ponies and they later went to a different rating system and it suddenly had 190. I know the boat was just as quick as before...
So does anyone know? It the 280 hp rating is now 266 what is the previous torque rating of 270? 264???

HP = (TQXRPM)/5252
With that said, yes, the torque rating will probably fall with the new HP rating.

same thing will a lower rating.......it won't go any slower....right.

If the powers that be suddenly change the system for measurement of height, and the "recalculated" figures now show my former 5 Ft. 8 Inches to be "restated" as 7 Ft. 6 Inches - It doesn't really matter - I still can't dunk !!

I'm done with my rant, now.

also, you guys are forgetting that it is OPTIONAL for the manufactures to rate their current engines under the new SAE test. All new engines will be rated under that test, but as long as they dont change anything on the engine, then they can claim what they have been claiming for the engine HP and TQ.
