2021 2.7L with new updated tow rating.

[f8l vnm]

Looks like the 2.7 now is able to tow maximum 9300lbs. What are your thoughts on this ? I’ve driven a new 2.7L and it’s a peppy little motor and has really good torque down low. But do you guys think 9300 lbs is too much for a 4 CYL in a truck ? 
Also the oil burner is now at 9500. With 460lb of torque I would have thought it could be more? I really like the new 3.0 and would consider it in my next truck.

Not really, it's similar torque to the 5.3. Why does it matter how many cylinders it has if it's putting out similar torque?

I have the 2020 and that thing can definitely tow more than it's rated at

My question is... are there any actual mechanical changes to the 2.7L and 3.0L to get the certification for higher tow ratings? 

 

Or does this basically back-award the same tow ratings for 2020 and 2019 trucks with the same engines?

Only thing i read was cooling , so maybe there were things done ? 

 

Also how is the Diesel and 2.7 so close in towing when there is about 100 Pound feet of torque difference ? 

 

if anything i'm impressed by the 2.7 and little disappointed in the diesel .

 

Lastly though anything over 10k , I would want a 3/4 ton anyway but just thought it was odd they are so close

I'm super impressed with mine. Honestly drives a lot like a baby diesel with the low end torque but with the benefits of gas.

And yea, I was thinking the same thing. My '17 LTZ had the max towing package but there's no way I'd feel comfortable towing 11k pounds or whatever that was rated at.

Because it has another 33 hp which also matters and weighs a sizeable amount less (roughly 150+ pounds not including the other emissions stuff added on) as well as other factors I am sure such as cooling and engine design parameters/requirements.

The diesel weighs less than the 2.7 even? That's interesting, I know that was one of the reasons mentioned for the 2.7 having so much less towing than the 5.3 given similar-ish power output. It weighs a lot less.

The 2.7 is working a hell of a lot harder to make power numbers up there with the 5.3.  I look forward to the long-term reliability results.

Lol okay. Based on hitting peak torque at 1400 rpms?

That's so archaic.

I personally believe the 2.7 motor will be durable over the years . 

GM spent a lot of time/money developing this motor  and who doesn't love Turbo Boost! 

They are also starting to use it in car applications like the Caddys which in most powerful form makes 325/380 , so the Truck application is actually tuned down .

No.  It's based on a having a BMEP that's nearly double that of the 5.3.

Having had the first gen EcoBoost in my 2012 F150, I would skip any turbo gas engine going forward. Just give me raw NA power and leave the turbos to the diesel folks and the fart-can tuner kids and racer-wannabes. /s

 

Seriously though, my F150 was fast as lightning when unloaded. But slap even a lightweight trailer on the back and your fuel economy just plummets. Yes it had the power (for the first 100K miles), but for my money, I'll buy a V8 every time.

I would love to see my towing numbers go up! Is there any update? Is it just the cooling? 
 

I love these topics. Almost every 2.7 owner loves the engine, and most of the comments are opinions from people who have never even driven one.

No, the engineers were asked to re-certify at higher tow ratings and they could because there was reserve capacity in the cooling systems.

Agreed this is a good thread.   I don’t see any complaints about the 8 speed really.   That’s also a good sign.
