This is sad. I would expect garbage like this from Ram or Toyota, but not the General. Why would a sane person pony up extra money for an over complicated 4 cyl when they could buy a 5.3 that's more reliable and cheaper to build. Makes no sense.

Nothing to be sad about!  I think the General is going out of its way to keep loyal customers like you and me happy.  They're keeping all of the current engines and introducing a couple of new choices.  You can still have a 5.3 and I can have another 4.3!  I am quite intrigued by the new 4 cylinder gas engine and will be interested to see if they are a significant upgrade in economy, durability and performance over the current V6.

REAL trucks get the job done without a turbo.

Well it may be the start of more turbo options to come from the general.....Damm you Ford !!!! lol. Me thinks if the General hangs some turbo's off the 4.3 v-6 in the Future for a option.......Ford you are toast .

Two things about this 4 Cylinder.

1) Could this be GM’s run around with CAFE standards? Offering an engine option could suffice this strict rule.

 

2)The fact that this 4 Cylinder gets that much power compared to Ferds V6 is pretty awesome. Makes me wonder what they have in store later in this generation line.

Chevy once again following in the footsteps of ford... They may make a better product but it’s impossible to deny that Chevy is playing catch up with Ford in some aspects. They may catch up and surpass but it’s still catch up. It is as if they wait for Ford to try something innovative and when consumers buy it Chevy jumps on board and makes it better. Clever

Ecoboost killer!

Yuppers!  I will be coming back to GM in 2-3 years and getting a 2.7 Turbo I-4.

Damn, that little four banger is impressive.

And, for some reason I feel more comfortable with a 2.7L turbo I4 than a 2.7L turbo V6.

Maybe it's because of the displacement per cylinder what gives me a better feeling about this engine.

I'm going to test drive it!

This torque curve is what I'm looking for. Easy, available, confident.

 

so long

Impressive, but I'm glad I won't be the guy having to work on these things in the future. They're making them harder and harder to work on in your own garage.

It may be designed for a truck, but I'll bet it would be a great crate engine for a small sports car or V6 camaro.

Kind of how apple does things with Android. Android gets the features first, but apple always knocks it out of the park when they get similar features a year or so later

I can’t believe the torque they obtained out of a 4 cylinder at just 1,500 rpms.  This little motor produces more torque lower in the rpms than the 5.3. Sure the 5.3 has a higher max torque but this 4 cylinders curve looks much more useable. Looks like it will only be standard on the LT and RST trims, but these trims will have an option of the 5.3/8spd. 

 

I dont want a turbo in my vehicle either but the writing is on the wall that it’s the future. Natural aspired motors may become a thing of the past with increasing CAFE standards.

I will stick with a V8, preferably one with pushrods and a single cam. I have really tried to understand what you guys are so excited about on this new engine and I don't see it. I typically opt for the larger engines and like power. I pull trailers and run bigger tires on all my trucks, so I like the pep.

Exciting would have been a turbo on the 5.3 or more power from the 6.2, or even turbo on the 4.3. Some of you seem to like turbos so good maybe that's what does it. I had a Duramax and it had a turbo. My tractors all have turbos...they are diesels and built differently. My opinion and I know it is not following modern wants.

Putting turbos on a 4.3 is a waste of time, with any luck the 4.3 will go away, it should of been shelved years ago.  The 2.7 GTDI has 310HP and 338 foot pounds which peaks at 1,500 RPM and stays flat.  A 5.3 does not have that much useable torque that low with that flat a curve.  It will get the job done and give better mpg than the V8’s.

 

With the success of Ford’s evoboosts I applaud GM.  DOHC/OHC engines have been around a long time and have proven their durability.  This new engine will get GM a lot of sales, and bring customers back.  

 

After having My Hemi Ram, this will get me back in a GM, but this is the only way.  The 5.3/6.2 do nothing for me.

 

But if their pricing is insane, it could be a Ford F150 2.7 Ecoboost.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Have considered installing a DC to DC charger in your camper to replace your isolator?

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
