Replying to Topic 'yeah why the 6???'
I suppose it comes down to price and how much horsepower you can put into a front wheel drive car. Have you ever noticed, especially with cars, that they can't handle all the horsepower, the whole front end seems to shake and whatnot when they are really pushed? To go up to 250 or more hosepower and use it effectively they'd probably have to make it All Wheel Drive, which would drive up the cost. There is something smooth about the way the 2.3 4cyl pushes at the moment. More horsepower doesn't seem necessary.
Mazda has to combat an unwarranted inferiority complex in Europe and in the USA and they'd never be able to charge what you might pay for a BMW, Acura or Audi. Therefore, I guess they've gone with a slightly lower horsepowered car to keep the price down.
I'd have to agree that they should have tried to match the 6cyl HP of a Honda or Nissan for the USA and Canada. Although, here in Australia Mazda's 2.3 is about as powerful a 4cyl as you can get.
As Mazda sits now it is a very good handling and stylish alternative to a Honda or Nissan. There really is not much chance they'd be able to sell an AWD car at the price of a European car of good reputation. I guess they are going for the same image that the MX5 (Miata) has as well - a car that DRIVES well. And in most cases they've succeeded.
