Subaru 2.5L Turbo Wins 2008 Best Engine Award (in its class)

Power rating and output is not the only measure of an engine. the v10 is a more unique and elegant engine. The ls7 is still just a big ole' pushrod V8. Not that thats a bad thing, its just not special other than its power output.

Not one American engine. 8 German/3 Japanese. I think its because the judges are from around the world so they have more exposure and appreciation to imports. I think the BMWs are offer in more markets compared to the Corvette.

The thing is, American engines are good, but they aren't blast-off fantastic new novel technology.

 

We'll see when the new iteration of the Ford Boss V8s come out...

 

But american engines aren't really pushing boundaries, other than just in displacement.

 

VVEL, Valvetronic, variable compression, direct injection (although US designed engines are adopting this), sequential turbocharging, and other things... US is in the mix, but not setting the pace.

 

I wish they would, actually.

 

Ecotec has been one of the forefront engines for the US, but that is one, and Mazda's DISI turbo MZR engine is also right there, as well as Audi's FSI 2.0T, and others.

 

Not to say that the US builds bad engines, they build good ones, but they aren't on the forefront the way BMW usually is, and other companies can be, including Mazda and Subaru.

 

Keep in mind, BMW has been an engine-specialist company since well before WWII, and they continue to put emphasis there.

Ok, GM got the LS7 (freakin 7 LITERS) to spin up to 8000rpm reliably....they only limited it to 7000 because it doesnt make power above that. It cuts out cylinders to get 32mpg on the highway. And all that with "old technology" that can be manufactured reletively cheaply. Who cares that it has pushrods? Who cares that they refined the shit out of old ideas instead of coming up with new designs? Massive power in a reliable package with proven manufacturing techniques for a reasonable price....what the hell else do you want in an engine?? As an engineer, I think GM's LS series is brilliant.

the hp/liter record of the ls engines isnt do great. the 7.0 ls7 only makes 505hp. thats actually not so great for a 7.0l NA engine and its hardly groundbreaking. other manufacturers atain equivelent numbers with less displacement. the bmw v10 is a much more efficiant engine making the same power with less displacement along with the uniqueness of being a v10 and the ability to make power above 8k rpm while including all the latest engine technology.

i think our 2.5 was the least techy engine on that list, just shows she's a ringer :)

 

This may be a stupid observation, but the classes seem pretty narrow. Since the Audi/VW won in the 1.8-2L category, what was the level of competition for Subaru in the 2-2.5L category? Any good competitors in this mix? Does BMW still use a 2.5L engine?

but thats my point....who CARES what the displacement is?? If I told you that GM made a 24mpg engine that's 505hp (AND 470tq!), and it's 2.5L, would that make it better than 7L? It's the same result, and thus does not matter. I'm all for technology, but almost everyone in this thread seems to think that technology automatically makes an engine better, when this is completely false. RESULTS make an engine better, and to me, it doesn't matter how those results happen.

 

I'd rather have GM's 470ft-lb at 4800rpm than BMW's 381ft-lb at 6800rpm. Its a freakin NA V10, there is no excuse for making me wait that long for it to make lackluster torque. Hell, my stg2 LGT makes ~380ft-lb at 3000rpm! And it has less than half the cylinders. This v10 is a joke.

 

For the record, BMW v10 gets 23mpg hwy, LS7 gets 24. WTF is the advantage of the BMW motor? Why is it winning all these awards??

While I agree in general, dbrunone, another important aspect of the engine is how it fits with the rest of the vehicle. The BMW V10 (not to mention the Porsche 3.6L H6 and the Subaru 2.5L flat 4) is a lightweight engine that can sit low in a vehicle. There are big advantages to both of those attributes. The LS series has a pretty vertical form-factor and are heavy engines, even relative to their large displacements. As a result, the vehicles they reside in have to be engineered around their weight and height, instead of opening up engineering options for the rest of the vehicle by being light and low.
Ich bin echt viel netter, wenn ich nuechtern bin. Echt!

Actually, the ls engines are pretty light and compact for ther displacement and the lack of an over head cam valve train keeps the weight center low even more now that they are made out of aluminum. they just are nothing new, and are only a larger or more updated version of their older brother, the ls1.

Lol BMW was one point behind the Subaru... it really makes you wonder how BIASED this organization is towards BMW...
The awards are presented each year at the Engine Expo in Stuttgart, Germany (home to Porsche and Daimler).

Is the Acura RDX powertrain in this category? Don't know if you guys have gotten to drive any of these little SPORT utility vehicles but they are pretty outstanding. 2.3l I-VTEC Turbo 4 cylinder, and the automatic transmission with paddle shifters= one of the most fun combinations I have driven. Definitely try to get into one of these and test it out if you can, stock for stock rivals the 2.5T found in a lot of Subarus IMO.
