Asians oversell horsepower
WASHINGTON -- After years of touting ever higher horsepower numbers to win new customers, Toyota Motor Corp., Honda Motor Co. and possibly other automakers are now backtracking on some of those claims.
Strict new tests developed by the industry's top engineering group are prompting the carmakers to roll back horsepower estimates on several key vehicles, including the Toyota Camry, America's best-selling car, and Honda's luxurious Acura RL.
For the 2006 model year, Toyota says its Camry equipped with a 3-liter V-6 engine generates 190 horsepower. In 2005, Toyota said the same car with the same engine had 210 horsepower.
The revised ratings comply with new Society of Automotive Engineers standards designed to eliminate subjective interpretation in establishing horsepower claims.
While Toyota and Honda are retesting their entire vehicle lineups, other automakers generally are retesting only cars and trucks with updated powertrains.
Over time, most automakers are expected to comply with the new guidelines, and horsepower ratings for other vehicles could be revised.
Detroit's automakers say they have been conservative in calculating horsepower and don't expect to have to reduce horsepower ratings on many vehicles. In fact, after retesting, the Big Three have revised horsepower ratings upward on several vehicles.
