Mazda Claims its Skyactiv-3 Will Have Lower Emissions than Electrics!

Mazda’s upcoming HCCI motor will have 56% thermal efficiency, and Mazda says that will make it more emissions efficient than all electric vehicles.

The company apparently uses creative "well-to-wheel" calculations to compare its internal-combustion technology against electric powertrains.

Mazda has made a bold claim that its third-generation Skyactiv engine technology will have lower "well-to-wheel" emissions than an electric vehicle.

After the second-generation Skyactiv-X models begin arriving on the market in the next year or so, engineers will be tasked with maximizing thermal efficiency in the next generation of gasoline mills known as Skyactiv-3.

Speaking at an automotive technical conference in Tokyo, Mazda powertrain chief Mitsuo Hitomi claimed Skyactiv-3 engines are expected to deliver unprecedented thermal efficiency levels of up to 56 percent, a 27-percent improvement over their predecessors, according to an Automotive News report.

The Japanese automaker is said to calculate that its gasoline engines will actually be associated with lower emissions than pure battery-powered electric vehicles. The AN story does not include specific details of the internal study, though it is said to consider carbon-dioxide emissions from natural-gas powerplants that charge EVs. It also reflects emissions from oil extraction and refining.

Thats kind of funny actually. Seems to me that it would take a bit more than some really creative calculations to show that a gasoline powered car was more "emisions efficient" than a car that produces zero emissions as measured by the EPA ? Perhaps they included the pollution created by producing the electricity needed to charge the battery, the environmental cost of making and disposing the batteries, any sort of pollutants that are emitted by the batteries during the useful life of the car, etc?:dunno:

I'm glad they are making such achievements in fuel economy... Go nature and all...

If there had been one snippet about a Mazdaspeed coming in the future though... I'd be much more excited.

Yeah, making calculations comparing emissions produced by various types of energy / fuels and the motors / engines that use them is a tricky business and subject to great interpretation.

For instance, there would be a lot of difference between electric energy generated via coal, oil, natural gas, nuclear, hydro, wind and solar, as an example.

The same would apply to the gasoline / diesel fuels and their many blends produced variously from oil drilling, fracking, sugar cane, corn, used cooking oil and other such sources.

However, I think Mazda's thinking "outside of the box" on many of their projects is exciting and has a potential to make some outstanding progress regarding fuel efficiency and emissions reductions.

This topic could be debated until we are all old and grey. In a world where making profit is the number 1 goal, no real progress can be made, because every single piece of information is skewed one way or another to help keep one side or the other profitable. Electric cars are the future, no but Mazda has better emissions, but does that include battery disposal, coal emissions from power plants blah blah blah blah blah, and it goes on like this forever because all these blowholes are just saying this crap to boost their own profits. They don't give 2 shits about the planet or the environment. For all we REALLY KNOW, they are both making things worse for the environment because we cannot trust their reports or the reports by the governments who bail out companies like GM/Dodge because of piss poor management just to protect the governments taxes. This is the hard truth that nobody wants to admit.

Yeah, it has a lot to do the the bottom line.
My opinion is Mazda is taking a bit of a gamble here. The small diesel powered car was for years king in many countries. Now, because of emissions issues and how those emissions are being tied to cancer rates there is a growing move to restrict and/or ban them, leaving a void in the market. It is entirely possible that Mazda is making a move to fill this void by producing a gas powered engine that meets the ever increasing European emissions standards. If they could bring to market a Mazda 2 or 3 that has the fuel efficiency of the small diesels car so popular in Europe, they would be in a position to sell a lot of cars.
