Mazda is developing a new ignition process that the company hopes will improve fuel efficiency in gas engines by 50%.

Mazda currently uses gasoline engines with 40 percent efficiency. The aim is to get that number up to 60 percent by 2020.

According to Autocar, Mazda is developing its homogeneous charge compression ignition technology (HCCI), where the mixture is ignited by compression rather than a spark, similar to a diesel engine. As a result, the technology will require raising the compression ratio from about 14.0:1 to 18.0:1 with a precise control of the combustion chamber in order to avoid engine knock. Mazda hopes the technology combines the cleaner emissions of a gasoline engine with the fuel economy of a diesel.
Mazda is also looking for ways to reduce heat loss through the exhaust system. This normally accounts for about 30 percent of the fuel's energy.

Now this is what I like hearing, finding efficiencies in the current system rather than venturing out into entirely new powertrains.

This is what should help Mazda seek the growth they want over the years, absorbing a lot of folks that want affordability, value and efficiency.

To me it doesn't matter if it is gas, diesel or electric, I just want a great engine for a fair price. Good power, good efficiency. Mazda seems to get that.

Ultimately that's what it comes down to for me as well.

I'm looking for reliability and gas mileage. With good range i'll be happy enough.

Do you think that kind of improvement is really possible by 2020 though? I'd be very impressed. From what I've seen, fuel economy usually doesn't improve that quickly.

It`s possible.

We don`t know how long they`ve been at this exactly and we have a while to go till we meet 2020. With the things they`re looking to do, they should at least come close to their goal.

I'm excited to see what comes of the cross-over marrying the Prius hybrid electric system with Mazda's SkyActiv-D diesel engine. That aught to significantly raise fuel economy right there.

Toyota wants to come out with a Prius SUV, so we might see something going on with Mazda and Toyota with that type of vehicle and platform.
