Toyota, Honda revise down horsepower claims

I remember reading somewhere that car manufacturers are being
required to report more realistic HP numbers, and that the
worst offenders were the Japs.

It’s happening. For example, the 2006 Toyota Avalon has substantially
less HP and torque than the 2005. Same goes for the 4Runner. Same for
the Honda Accord. Same for Acura:

2005 Acura TL: 270 HP & 238 ftxlbs
2006 Acura TL: 258 HP & 233 ftxlbs

Nissan publishes the same numbers as in 2005.

I wonder if we’re still being lied to.

    The SAE has created a new standard for measuring horsepower. It is now
    requires that the intake and exhaust systems to be used during the test
    are like the ones on the car (not necessarily exactly like the ones on
    the car, but with the same performance characteristics). Some
    manufacturers are affected more than others. Toyota and Honda seem to
    be the worst hit. If you were around in the early 70′s you should
    remember a similar hit to horsepower numbers when the SAE procedure was
    changed from gross horsepower to net horsepower (Gross horepower was
    with wide open intakes and exhausts and accessories driven seperately
    (like an electric motor to circulate the water in the engine).

    The Detroit news had a table comparing some of the differences from
    2005 to 2006 –

    Horsepower ratings
    Vehicle                       2005 2006
    Acura MDX                   265  253
    Acura RL                      300  290
    Acura RSX                   160  155
    Chevrolet Corvette LS7  500  505
    Cadillac XLR                440  469
    Ford Explorer*              210  210
    Honda Civic                  200  197
    Lexus LS430                290  278
    Pontiac G6                   200  201
    Toyota Corolla              130  126
    Scion xB                      108  103

    It is a new standard for all manufacturers.  So they all need to go back and
    re-test.  Some cars went up, some went down, some stayed the same.  Even though
    the numbers are slightly different, the Acura TL probably feels the same
    whether you have a 2005 or 2006.  Not really a big deal as long as everyone is
    using the same ruler to measure.

    It is a surprise to see "claimed dry weight" or "claimed HP" in many
    review magazines. Why these magazines bother to use and re-publish
    manufacturers data to public instead of publishing the data they
    measure themselves to assure accuracy of their articles? it is not too
    hard to put the vehicle on scale or other devices.
