Actually there's a really good chance that one version of the new 3rd Gen Boxer engine will be a 2.4L.

If you just cut two cylinder off of the 3.6 H6 guess what do you get? That's right, a 2419cc H4.

Lets see what Subaru can do with some modern technology and innovation before we declare the death of anything. Remember, this is the company that built family sedans that set world speed/endurance records and a production car with a drag coefficient of 0.29 in 1985.


I see crazy serpentine belt and very bent dipstick relocated to the front of the engine

Juding by the timing cover it's chain driven (meh) but with dual AVCS.

The actual displacement of the 2.5 H4 is 2,457cc.

The actual displacement of the 3.6 H4 is 3,630cc.

Subtract two cylinders from the 3.6, and you end up with a 2,420cc H-4, which is a mere 37cc less than the current 2.5 engine; certainly nothing to quibble about.

Geez Bob, talk about quibbling. Here's quibbling.

The EZ36 H6 is 3629.595cc so the E?24 H4 would be 2419.73cc

My point was that a 37cc difference between the current H-4 and a 2.4 based of the H-6, is pretty minor.

Some folks might get upset in using a "smaller" H-4, when in fact the displacement difference is very minor. With up-to-date technology, I wouldn't expect any power losses by going smaller.

I thought I read somewhere that the theoretical new Boxer engine was going to be "FJ20", or FJxx

EZ30 -> FJ20 with two fewer pistons
EZ36 -> FJ24 with two fewer pistons.

Plus there is a possibility of one in between... with the bore diameter of the EZ36, and the regular stroke length of the EZ30, and standard con-rods... an EZ would be in the neighborhood of 3.2 liters... an FJ minus two cylinders would probably be around 2.1 liters, or just under.

I wonder if it will have an EZ36-like bottom end, with an oil and water pump assembly under the front of the crankshaft...

Hey Beaverboy.. Whats Up

I did not say it was the death . It will no longer be STANDARD even Subaru said it in the article. Subaru does not have many cars, what 2, and they have to average 39.6. They have about 36 to 48 months btwn development and testing.

No they will have some crappy cars so satisfy the Gov. that no one will buy. We will pay a lot more for the models we want and theoretically pay for the one that do not sell. Plus 2K the EPA standards imposed on the new tech (that is Gov. # on the new EPA).

Now what you might get from this is a Forester STI it is a light truck and has to get 30 mpg. So the WRX Sti will be dropped for the Forester.

Also, why Subaru is telling the public they will be using Toyota's hybrid Tech. at this point in time is a bad business move. Just yesterday another Prius ran away. I would not hitch my horse to that crap right now.

Uh, they haven't! They have been pretty straightforward that it will be their own system because the Toyota system doesn't work with Subaru's AWD.

^^^

From the article posted..

Around the same time Toyota doubled its stake in Subaru’s parent company, Fuji Industries, and Toyota and Subaru were well on their way with sharing hybrid technology. “We agreed with Toyota to utilize the Toyota system in developing our own hybrid technology,” Mori said. “Fundamentally speaking, we can’t just plunk Toyota’s system into our own vehicles. We need to develop something that is adjusted to our products.

engine does not equal hybrid Technology

Whoa... I've been under a rock but what model is that going into?

I dunno if it's the picture but that motor looks tall

yo is that a dry sump setup?!? which would explain why there's an extra pulley(s) and also the upside down oil filter on next to the oil cap? this is probably also why the exhaust seems to be so close to the motor and all the stuff above the block is so high. maybe they are trying to get the motor as low as possible.

Hybrid Diesels have been used for years on the railroads. Electric motors have many advantages over fossil fuel. Leave the oil burner for the generators.
