Any idea if the horsepower will be lower in the US and Europe than in other places because of emissions restrictions. California, where I live, has the most restrictive emissions laws in the world. Many cars are de-tuned, even from the rest of America.

MazdaMan,

In a previous thread:

that I started, you told me that horsepower for the four cylinder will be 160 in the States. There is about a 10 hp drop from the European model. And DuratecPerformance thinks it is due to the lower octane in our fuel.

Whoops. You're right, I read that off of the mazdausa.com sight though, so don't blame me entirely. That 10 hp can't be that big of a difference. In California we use 91 in most of our gas stations. I'm sure we'll have an extra catalytic converter in there weakening the emissions and hp.

It's strange that the HP rating is lower here than in Europe. From Japan I would understand. Their gas is 99-100 RON and lower sulfer as well. Many JDM models get gasoline direct injection, which allows for improved gas mileage and/or power. If they used that with our gas, the injectors would go bye-bye very quickly. But we normally get better power ratings than the rest of the world.
The Subaru WRX for instance:
Japanese Domestic model: 240 hp
US model: 227 hp
European model: 217 hp
Australian model: 215 hp
It's true that European emissions regulations are less stringent. However they have economic disincentives for that. In England you are taxed on emissions.
