The HP of the car has not changed. Only the way they are allowed to
measure it. ie. using oil that would void the warranty and other
cheating methods to boost the number are no longer allowed. The 2005
would likely be given the same rating on the new system.

Good explanation.
However, most Honda models got HP boost from the new measuring system, I
doubt TL was cheating.

Is that true? I heard that the new Civic Si would have been over 200
with the old method, now it is 197(?)
