Mazda Claims 70 mpg For New Engine, No Hybrid Needed

thecarchik writes "There's no word on when the new version of the Mazda2 will finally reach the US but when it does we can reveal that it will return a fuel economy of 70 mpg — without the aid of any electric motors. This is because the car will feature Mazda's next-generation of drivetrain, body and chassis technologies, dubbed SKYACTIV. The new Mazda 2 will come powered by a SKYACTIV-G engine, Mazda's next-generation direct injection gasoline mill that achieves significantly improved fuel efficiency thanks to a high compression ratio of 14.0:1 (the world's highest for a production gasoline engine)." I wonder if a real-life-real-drivers 70 mpg car is what will actually arrive, or if such promises will dissolve like Chevy's promises about the Volt did.

Suspicious? Well... no.

Everyone's heard all the rumours of the Automotive Industry crushing amazing engine innovations that would give amazing efficiency. If this was true, and with the current climate making such things very desirable for both the consumer and public image, one would expect to see a startling number of such inventions coming out in a short space of time.

Are we seeing this? I don't think we are. Which makes this comment unprovocative and pointless!

Re:Suspicious? Well... no.

My favorite one being the poster's uncle's-brother's-cousin's-father somehow "stacking" carbs back in the '70s to improve fuel atomization, yet somehow the oil industry always buried the patents. Except that fuel injectors do a better job of atomization than any silly arrangement of carbs.

The origin of this apparently started around 1930. The patent would now be public domain. It was never used, not because the oil companies buried it, but because it does not, in fact, work:

More importantly, how much is it in furlongs per fluid ounce?

Code fix. If external_temp -20F, don't shutdown. Wow, that was *extremely* difficult.

Which part of 'burning fuel while stopped can never be a good thing' are you having a hard time understanding?

"Mazda expects it to come in at 28 mpg city, 35 mpg highway with the five-speed manual, and 1 mpg less on highway mileage with the automatic."

Does not compute.

28 + 35 = 63. That's not quite 70, but it's still a pretty respectable number.

So you mean you can use the tank twice as long as you don't spend it in the same environment both times? :D

I'd rather take the risk of being killed by someone else than the risk of killing someone else. Moreover, I have serious misgivings regarding the morality of the contrary position.

Well that makes you a Darwin-FAIL.

The code was written by Pudge, but he left recently. He learned all of his Perl by reading the book of Revelation. I told him that if he paid more attention to the minor prophets Amos and Habukuk it would help him write better organized code. But he wouldn't fucking listen to me. No, he was all "death riding on a pale horse" and all that shit. Fucking newb.

You forgot to add the five-speed manual and the 1mpg less...
28 + 35 + 5 + 1 = 69
