That's stronger than my tbi 350.

How do you feel, psychologically, about the 4-cylinder in the Silverados?

maybe by the numbers,, but you don't need to wing your 350 up to 4K rpm to make reasonable torque...
that's why towing is limited to 7k lbs. with the 4 banger.
I don't doubt that this truck may become popular for people who live in flat states with no towing needs that want a truck to do small jobs or throw a few sheets of plywood in the back once in a while.
It may even become popular with small fleets, but with the V6 and V8's getting as good or better mileage, I don't see the benefit and complications of adding a turbo and then twisting it to the moon to get any power out of it.

Everyone here is saying the exact same thing when Ford introduced the EcoBoost. Rabble rabble rabble not a V8 rabble rabble rabble. Meanwhile the 3.5 EcoBoost has been out towing the 5.3 since it's inception
Thank you for posting the numbers. Did anyone actually look at the torque curve? That's full torque from 1500 rpm to 4000 rpm. Sorry but no V8 has that flat of a torque curve and could deliver it starting that low. I'm not saying I'd buy one but the engineering into this 4cyl is impressive. And honestly I think it'd do better in the mountains with boost than an NA engine of comparable power.

Lol. You know anyone with Ecoboost? I know a guy.... Pulled a camper..... One summer and it was gone for a V8. People want what they know. Most Ecoboosts haul groceries and that's about it.

348 lbs from 1500 rpm, I don't have 348lbs anywhere out of my 350.

I really have to wonder where and how the HP and torque is measured....
flywheel? rear wheel ? First gear behind the 8 speed ?
I mean with 348 FT LBS at 1500 rpm, multiplied behind an 8 speed shouldn't this thing just roll up the asphalt under the rear tires ?
All things being equal with the rest of the truck compared to the V6/V8,
Doesn't make sense that the towing would be limited to 7k.... something is not right with the math ???

That's even better, starts with 348 at 1500 and climbs to 473 at 4000 rpm.
2.7 litres is pretty decent size already and with 22psi turbo it should be good.
The 7000 lbs limit might not be what the engine limit is, it could be marketing to give the v6, v8 an edge, and 7000 is no joke.
I don't think the 1/2 ton from the 80's with a v8 had that.
From what I could find 1998 Chevy 1500 2wd towing capacity is 7000 lbsI really have to wonder where and how the HP and torque is measured....

Look again.....473 is in Nm...

This video is a good compilation of the several videos TFL Truck did on the 4cyl Silverado. I talks about the positives, minuses, and compromises of having the 4cyl.
Oh ok, still more than my 350tbi
Sometimes the torque curve is programmed flat like that in turbo motors (just like some of the eco-boosts). 348 @1500 sounds great for towing, but I wonder how long it takes to build boost. I DD a turbo 4 Ecotec and there is no instant torque with that thing. Maybe the control system is fantastic, but I still think a roots blower would be better for getting a trailer moving. For driving around town a small turbo engine is great. Constant heavy loads at 1.5bar boost and 87-octane gas makes me wonder how long you can really get full torque, especially in high temps.

I DD a Turbo 4 Ecoboost. What a pile, that thing has to rev to 4 grand to build any boost before it gets going. A real pain sometimes in Chicago traffic.

My 1.8 turbo Jetta has zero lag and builds plenty of boost under 2k rpm. Zero problems pulling hills and moving out in traffic. I guess I'm spoiled...

Huh, the Germans have it figured out better then the Americans. Big surprise there.
I am pretty sure this is figured out the same. If it shows 348 lbs @1500, it's with the turbo spooled up, no way they that kind of tq out of the 2.7 otherwise

It was a joke man.
But the 2.7 is bigger then the 1.8 and 2.0 we were talking about. Also I am talking about the Ford Ecoboost. So there is that.
The 1.8 VW is rated at 170hp @ 4800rpm and 184lbs @ 1500rpm so going by the numbers I'd expect the 2.7 to have a similar power curve as the VW. If that's the case then it should be plenty adequate to move a basic half ton around without reving it out.
