He's refering to the new H-6 that will be available in the forthcoming Legacy. I don't think it's in production yet. It's rated at 245PS (about 242 SAE hp). It beats the two 3-liter's that come to my mind. Accord; 240 SAE and last gen M3; also 240 SAE. But the Boxster has a 2.7-liter rated at 250+ SAE hp.

let's not get it to the most hp per L in a NA motor....S2000??


BTW, I would buy a Legacy if it had 245 hp....and why not turbo that anyway?

Since we're considering 6-cylinder NA 3.0L engines anywhere in the world, the 1994 Euro version of the BMW M3 (with the S50 B30 3.0L inline-6 engine) was rated at 286hp @ 7000 and 236lb @ 3600.

I was ready to buy the LL Bean Outback with the 210 H6 until I drove one. The slushbox, which is the only available transmission, makes that thing a complete dog off the line. I understand the awd system works very well and it has nice pull once you are moving. However, you will occasionally be sucking hind tit from a stop light, which makes jockeying for traffic position a little more difficult.

An reasonably powered Legacy (220 hp or more) with a 6 speed manual will be my next car in 4-5 years if it is available.

I bought my wife the 2002 H6 LLB Wagon. Very comfortable, smooth as can be.

Total dog. A hamster could go faster than this thing in any gear. A hamster with two broken legs to could faster than this thing.

But it's smooth and very comfortable - very very smooth. Nice for taking on a long trip with all the goodies - heated everything, power everything - auto everything.

Just don't try to pass anyone...

rotary motors are completely different, and 1.3 is an incorret measurement of displacement. Rotary motors are doing 3 things at once, intake, combustion, and exhasut. I would say since its doing both intake and cobustion at the same time on the smae rotor, that the "1.3" liter motor is 2.6 liters in reality. Also, since on an na motor the displacment of a motor is really how much oxygen you can get into the cylender, its a measurement of how much air your motor breathes. And since its intake and combustion is happening at hte same time, it breathes just as much air as a 2.6 liter motor ;-). Then again 2.6 liters isnt a huge displacement for the amount of power they are putting out... 250 out of a 2.6 isnt bad at all na, but with the rx8 there isnt much torque :-(. Yet compared to the sk2, its only 10 more horsepower for .6 liter more displacement.

Nah, I just brought up the Boxster motor, since it's a NA H-6 that's close to 3 liters. It mostly fit the criteria, but is actually smaller in displacement. But Jon [in CT] got the Euro M3, which is (was) an awesome motor.

Edit: Oops, the Boxster's 2.7 H-6 makes 225 SAE. The Boxster S' motor is rated at 258 SAE, but is 3.2 liters. Also, the older NSX's had 3 liter V-6's that made 270 bhp.

I do not believe that they are superior, but you have to admit it is very impressive when they achieve a high # of hp/L. I still appreciate american big blocks that lose this debate EVERY time, in the end.... "there is no replacement for displacement"

Interesting how rotaries act like engines 2-3 times their volume. They still have just as many combustion chambers as their 6 cyl counterparts.

Big V8s may never make the impressive hp/L that small high winding 4s do, but they sound and feel great when the pure torque is put to the test. I LOVE my RS, but I'm in a whole other world when driving my Cuda. (small block making about 75hp/L, pretty pathetic)

... no
only 2 combustion chaimbers.
it's still a 4 cycle engine, yes, but cycles are completely different then a conventional engine...

any way,this is off topic, go read howstuffworks.com

Isn't porsche making a 380 some HP flat 6... not sure if it's a 3.0 or not.

Thanks for alerting us, but are these 3.0L engines, as mentioned at the top of this thread and the subject of this discussion?
