Does anyone know of any other applications for this engine? It has been talked about a few times by GM to be paired w/ the 6 speed auto. But I have heard of no other vehicles that will see this engine. Is this another situation like the current Equinox's 3.4 where it is pretty much the only thing w/ it?

I believe it will eventually replace the current 2.4L. Next Impala should have it. And as GM redesigns its cars they should get GDI engines.

better be 200hp minimum

tq>hp

don't forget NA 4xclys don't make any torque!

A 2.3L is failry large..it will be ok TQ wise

Eric Bryant

The whole purpose of the transmission is to convert torque at one RPM to more torque at a lower RPM (or, in the case of overdrive ratios, we're giving up some torque to gain revs - but the final drive ratio still remains greater than 1:1). With a 6-speed gearbox and a properly-designed torque converter, we can very efficiently trade torque for RPM - and since torque x RPM is what gives us power, what we really want is power and not torque.

And FWIW, in a N/A engine, you're pretty much limited to about 75 lb-ft/L (maybe GDI can push this a bit higher due to lesser pre-ignition issues). Where you place that torque in the powerband is far more complex.

For marketing purposes? Most people looking for a fuel efficient cross over won't care what the HP # is.

Ford will sell more 4 cyl. Escapes this year than ever before and they are only ~170HP

For the purpose of getting a good solid number. Getting t down the road and up hills with less effort.

If its the latest and the greatest--and has a number of high tech inovations....why not?

A better question is why you want a lame 170hp?

Thats what my 2.4L Ecotec makes right now. Quad 4s were doing even better then that over 10 years ago...

If GM can get great mileage and good hp why not??

But go ahead....shoot for mediocrity

what gdi stand for.

Z28x

The goal should be economy, mediocrity would be if this thing put out 200HP and got the same mileage as the current 3.4L V6. Those looking at HP will buy the V6, those looking at MPG will buy the 4 cyl. Best in class mileage will sell more cars than best in class 4cyl. HP. Don't forget there is a good chance gas will be $5 by the time this new Equinox comes out.

Gasoline Direct Injection (many just call it direct injection)

305fan

The goal should be BOTH. Like I said a 2.4L Ecotec makes 170hp---you think adding DI should not increase the HP--and keep gas mileage? Hard to beleive what I am hearing.

Yeah I know--buyers who want more power will get a V6---thats still no reason to short-sell the 4cly

Don't forget the Equinox is heavy for a smaller SUV....and that Vue is a pig for weight. Hurts performance all the more

Z28x

I'm sure we will get both, but if a tune that puts out 190HP gets 1mpg better than a 200HP tune then they should go with the better mileage. 6 speed auto should help out a lot with both mileage and acceleration.

305fan

yeah the 6 speed auto is great--it cut 0.7 off 0-60-- 0.4 off the 1/4 and got better gas mileage (in the 2.4L Malibu)

I'd love that in my Cobalt

ok could live with 190. I just tire of the same old, same old.

hey01

this is exactly why honda and the like have zingy 4cly engines with no trq. They said, screw that if we put small enough gears in it we don't have to worry about it! although now we have to make our engines rev to 98,000 rpms so these 4.55 gears can take the car over 40 mph.

I'd like to see 200hp too but if the new motor has 170-175hp and just one more mpg... GM has won the battle. The writing is on the wall that gas will be $4.50-5.00 a gallon next summer. If the added power of DI in the 2.3L is taken off the topend and moved lower by using a longer intake tract drivability would be great. The 3.6L seems this way pulls nicely from as low as 1200 rpm.

GM is still lacking in technology under the hood in my view. If the want to return to greatness they need vvt, variable intake, and DI on every motor. I dont know if this new motor has a VIM or not but lets hope so. If it does 200hp would not be out of the question. I'm also waiting to see GM replace the 3.6L car motor with a DI 3.2 for the FWDs, if not where the heck is is DoD for this motor. The 26mpg rating is poor.
