There are no simple engines these days, Some may appear simple and have lower parts counts, but every one has more hours of engineering into it than I have in my lifespan.

The tech is all in the subsytems, piston/chamber design, Bearing surfaces, material composition. Injectors, sensors, ECUs. Thermodynamic research. Even chemical research.

Don't fool yourselves into calling a LS series motor or a plain jane Focus motor simple. As much engineering goes into those as any Ferrari V8 or Porsche motor. It just manifests differently with different goals.

Also keep in mind that the actual combustion is getting more efficient, so mechcnical losses are back in focus again. Things like the fact that fewer, smaller bores have less friction (rings/piston-to-wall) than larger ones. So all other things being equal, a small 4cylinder making 200 "internal" HP will "lose" less of it to friction (and inertia too) than a V6 making the same "internal" HP...So the V6 would use more fuel for the same "external" HP. All of that seems trivial to me, but I'm sure it's not to a manufacture making 100Ks of cars a year..

For the soapbox:
The enemy of MPG is, and always has been, weight. More efficient engines are helping, but weight is the root of all automotive evil. 1984 Honda CRX, 45MPG (IIRC), carburated motor, still yet to be matched by any non-hybrid gasoline powered car. Not that I want us all to drive old CRXs, but it illustrates that weight should be a bigger EPA target than forcing more efficient motors

Lighter cars crashing into you in accidents would be nice as well...

NHTSA and IIHS can't be rendered moot and useless by rolling back the mass-inducing safety regulations that they have implemented.

Nevermind that they are in direct contradiction to EPA energy efficiency regulations, and at some point, additional safety-reg induced mass is self-defeating due to the laws of physics. that just makes too much sense for a bureaucrat to wrap their tiny little mind around.

What Was Subaruís Motivation?
Subaruís motivation for developing the new smaller powerplant was not to win any awards. They did it to see if they could develop a smaller turbocharged engine that would surpass the current 2.5-liter engine output that is used in the North American 2015 Legacy sedan. The new LEVORG Sports Tourer was developed for the Japan and European markets and they needed a more fuel-efficient engine for the sporty wagon.

Why Did They Do It?
Fuji Heavy Industry engineers increased the compression ratio in the new turbo engine, but they also wanted the new engine to use regular unleaded fuel. This would give the LEVORG a big advantage over the European turbo engines that required higher octane fuels, but had the same hp ratings as the 1.6-liter LEVORG. And they succeeded by designing a new downsized turbo engine that had the same power output, used regular fuel, but offered superior fuel efficiency and the same power output of the 2.5-liter.

1.6-Liter Outperforms the New 2.5i Legacy
The new North American 2015 Subaru Legacy model equipped with the 2.5-liter engine produces 175 horsepower and 174 lb. ft of torque. The new smaller 1.6-liter horizontally-opposed direct injection turbo "DIT" engine in the LEVORG produces 125kW (168 hp) and 250Nm (184 lb. ft torque). They succeeded in a big way and demand for the LEVORG Sports Tourer is high.

The new Subaru LEVORG 1.6-liter horizontally-opposed direct-injection turbo (DIT) engine combines a direct injection turbo and a small displacement engine that provides both outstanding fuel efficiency and sporty performance. It has a high compression ratio, but takes regular 87 octane gasoline by performing a dense knock control. It also is Subaruís first engine to come with ďidling stop" for improved fuel efficiency.

Hey, you had to say "news" to say their name, didn't ya?

"News" just means a presentation of information, which this is. I know you have better things you could be doing, so go ahead and do them.

autoomobile, torque news, and motoring crunch are not news. Referencing them for anything ruins your own credibility.

Quite the ad hominem rebuttal. SoDealer's right - your credibility is _______. (fill in any word synonymous with zero)

As an early (2001) member of Nasioc, and owner of 9 previous new (primarily turbo charged, manual) Subaru, I, too will positively attest to Chano's creds.

He is sometimes overly consistent in opinion, but always with a sense of ironic humor. As someone who regularly logs 30k Suby miles annually, I enjoy his road worthy perspective.

Keep on keepin' on, Chanoman..

Sodealer, could you be more smug?

Let's think of like this: Was this thread doing anything to begin with? No, not for a long while. Was SOMETHING discovered that pertained to the thread's topic? Yes. Have entire threads been created upon LESS information? Hells yes. SO WHAT THE **** IS THE PROBLEM?

My goodness people, you're really making something out of nothing. If you don't want to take the information as "News" then brush it under "Rumor", it's just that simple.

And thanks guys. I thrive on consistency!

@a2cpc, it's actually been warm and rainy recently. Then it freezes at night, so I get to slide sideways into work! Ya'll in the Lower 48 have been taking all our snow... GIVE IT BACK! My BRZ enjoys snow way more than ice.

Hopefully Mahwah, NJ, will be more fair to me.

We've only had snow twice this year, one day of which it was also sunny and thundering at the same time. We need more too, my winter tires are going to waste!

Well your cred isn't doing too well yourself, sport. Your word on the street in the other thread is dead wrong. Don't quit your day job

plastic conducts less head so they use it on the intake which connect to the hot engine. on the intercooler cool side I don't see why they'd use plastic over aluminum other than cost elsewhere

No kidding. Some of you need to get a girlfriend or even a dog or something to take your mind off your dreams of Subaru bringing the Levorg over. Take if from an older guy, life is short. Really short. Find ways to enjoy it to the fullest not pining for things that may never come.

I love these threads about "get a life buddy" that take up time and thread length to write.. ironic. If we didn't have dreams of Subaru I'd hazard to guess 99% of people wouldn't be on this site!

I do do I do! I meditate to thoughts of a 5.0L DIT engine mounted below the front axle and the BOV routed to my iphone while I drive.

All I'm say'n is people are so quick to criticize on the these forums and sound self righteous.. hiding behind anonymity and self importance over a few words lol its very amusing to me that they then take the time to respond.
