1. Japanese sports cars

It became a joke that all Japanese sports cars produced between 1989 and 2005 had horsepower ratings of less than 280 hp. The most common number you will see is 276 hp, but not more than that. The Japanese manufacturers had a gentleman’s agreement that the hp ratings of their domestically sold cars would be up to 280 hp and not more for safety, environmental and insurance reasons.

But, as you know, almost all sports cars produced in that period delivered much more than just 280 hp. Just think of mighty Skylines, Honda NSX, Supra Turbo, Subaru Impreza WRX and all those cars had over 300 hp straight out of the box, and much more with just a mild tuning job. The Japanese underrating has become famous in the industry since it was obvious that it was a deal that nobody respected, and it lasted for almost 16 years.

Finally, Honda introduced the Legend with 290 hp and all bets were off. The rest of the Japanese car manufacturers followed and today we have true ratings to their models.
