power (kW) 206 torque (Nm) 363
These are the numbers I have found on the site for the TT's power.
I have tried to search for this info..but I find it quite hard to find an actual definition of KW and Nm.
Could somebody explain to me what these mean? And what the difference is from the 260 HP that toyota says these have. I know there is difference between actual horse power at the wheels and how much it produces...so please and thank you.
Thanks,
Tim

You will find these are the 'claimed advertised power' given by Toyota JP.
These are also the same power stats for the 2.5 Turbo Skyline, the 2.6 Tiwn turbo all wheel drive skyline, the Nismo released 350z, and numerous other Japanese domestic released performance cars.
Japanese motoring organisations developed a 'gentleman's agreement' for power ratings after the japense government politely asked them to limit power production in their cars, so most cars that came out with 206+kws where tagged as developing 206Kw.
I am sure the Soarer 1jz in fairly stock form gets something like 187Kw at the rubber, which is closer and more realisticly 220kw at the flywheel, but I am sure someone will come and correct me on this.
As for Horses, they are around 260hp (Horsepower is roughly 1.26 times more than KW)

From Experience what ever your car puts out in kw at the fly will roughly equate to what it is putting out at hp at the rears. So if the car has 206kw at the fly, which is 276hp. Means that it will roughly put out 206rwhp. Taking away a few hp for the driveline. Then you just convert the 206rwhp to kw which is around 153rwkw. So back in the day a TT put down around 150rwkw and the V8 was around 142rwkw. It's not exact but this is what we have learned it works out to.

Newton Meter (N/M)- a compound measurement of torque - one newton meter is the vector equivalent of a joule.
Kilowatt - 1000 watts - a watt being a way of measuring energy produced or used - the equivalent of a joule per second (leading to the lame joke "watt is a joule per second?")

Shane there is no formula to convert power (kw or hp) at the rear wheels to power at the flywheel. It depends on losses through the driveline of the particular vehicle. The loss has both a fixed and a proportional component.

yeah your right it stock form they produce about 220ish hp at the wheels i think i had about 235rwhp with an intake and front mount
NM is the torque or staying power, so if you got up to speed in your car and drove up a hill it is the torque of the engine that holds it at that speed.
KW is the amount of force the engine puts out to move the car, so power is what gets you from 0 to 100 flat out
you will find most 12 and 13 litre truck diesel engines only have about 400-500 KW but anywhere between 1500-3000NM of torque which is why when your stuck behind a truck they are always slow to move off even if they are not loaded with cargo but once you get them moving up a hill you wont stop it
