New Mazda 6

[blackshine007]

I'd love to see a new 929-type car from Mazda...with another Miller cycle engine, haha.

I still don't know what's special about Miller cycle engines. Does that just mean they're supercharged or something?

Google time.

A miller cycle engine is basicly like this: During the intake process, as the piston goes down, the intake valve opens with it. on a regular Otto cycle engine (conventional), the valve is about closed when the piston reaches bottom dead center and as the piston returns back up, it's pressurizing the cylinder to make the most power. The miller cycle engine on the other hand stays open most of the time during the combustion process. Though not as much as staying in, it better promotes a better swirl for better gas mileage at the cost of not as much power. The stock Miller cycle engine (2.3L S/C V6) gets 2 mpg city / 1 mpg hwy better than the stock Millenia 2.5L and out powers it by 40 hp/40 ft lbs.

I think the technology was wasted, personally. It could've went towards a twin scroll turbo to get basicly the same gas mileage and still have enough space to do anything. Everything was expensive on the car, but they were reliable. I hope the Mazda 9 don't have a miller cycle engine.

I hope the Mazda 9 don't have a miller cycle engine.

I doubt it will (if they even come out with a Mazda9), especially with Ford poking its nose in almost everything Mazda does. If they even come out with a larger car than the 6, it will probably use the same engine as the top of the line Mazda6.

And for all the Ford fanatics, don't get me wrong, Ford probably saved Mazda from going under back in the 90s. But at the same time, they also stifiled Mazda's ingenuity, uniqueness, and reliability of it's best selling car.
