Turbo 4cyl Silverado

348 ft/lbs. For the same CI, quite a bit lower than the Ford 2.7EB at 400 ft/lbs. Better more fuel efficient, otherwise, it's short of Ford...

 

Well, the Ford is a V6, so even though they are the same CI, it is going to have an advantage.

Perhaps this is a stop gap measure for them to say they are offering a fuel efficient alternative while developing a small turbo V6. It seems it will be hard for it to compete with the Ford 2.7 due to the weight of the truck though.

It'll be interesting to see how GM buyers accept this. On one hand, GM had to do it because F-150 was eating their lunch with 2.7 ecoboost fuel economy numbers. On the other hand, GM buyers really love the V8.

 

It's also interesting that GM did it with 4 cylinders instead of 6. 2.7L is right on the very large end of automotive gasoline 4-cylinders but not unprecedented. Given the torque numbers, it's obvious they're not pushing it as hard as Ford is. I wonder if it's a CGI block? That might explain why Ford can push their's harder....

 

Finally, the V6 in the F150 will be smoother than the 4 cylinder in the GM. But then the 4 cylinder should be cheaper to build since less moving parts, 1/2 the number of camshafts and cylinder heads, block boring operations is in one plane only, etc.

 

Anyways, it's nice to see more engine options for the GM faithful.

I believe this is there "base" engine according to what they are comparing it to on that chart.

 

I,don't know, there were decent 4.3L sales in 2014 and first part on 2015 around here. Now only the occasional fleet truck come in for a LOF.

 

Who knowS when we sold one to a non-fleet customer.

I doubt it, they have been working on this as an all new design for many years. I wonder if it shares the same bore & stroke as the 5.3L? I doubt we'll ever see a TTV6 in a GM truck. They will probably go to a small displacement TTV8 before doing that.

- DETROIT — The all-new 2019 Chevrolet Silverado 1500 will be offered with an all-new, technologically advanced 2.7L Turbo that expands the range of available engines and builds upon additional choices to help customers find the Silverado that perfectly suits their needs.

Standard on LT and RST trims, the new engine delivers an SAE-certified 310 horsepower and 348 lb-ft of torque, for 22 percent more torque than the 4.3L V-6 it replaces. Developed specifically for truck applications, the new 2.7L Turbo inline four-cylinder engine delivers peak torque from 1,500 to 4,000 rpm.

The next-gen Silverado with the 2.7L Turbo delivers 0-60 mph performance in less than seven seconds and weighs 380 pounds less than the current Silverado with the 4.3L V-6. Compared with competitive full-size trucks, the Silverado 2.7L Turbo is expected to deliver comparable payload capability with greater torque than the 3.3L V-6 in the Ford F-150 XLT and the 3.6L V-6 in the Ram 1500 Big Horn.

“The new 2.7L Turbo is a technological marvel, with our most advanced valvetrain,” said Tom Sutter, chief engineer for the 2.7L Turbo. “With a broad, flat torque curve and quick throttle response, it punches above its weight, delivering surprising performance and efficiency.”

How much less does the new truck weight with the 4.3L?

The 2.3LEB in the mustang gets the same 310/350 power rating but both are probably far more expensive than the base 3.3LV6 in the F150. I would guess fuel economy is also very very close. The 3.3L and 2.7LEV in the F150 are identical at least on the 2wd models.

Those numbers are also with 93 octane fuel, (Which hopefully becomes the US standard) While the press release makes no mention of fuel grade for this engine.

Did you see their camshaft setup? It has multiple lobes and a elecro/mechanical mechanism to change which lobe is running the valves. I'm guessing that's a fair amount of parts. Plus their variable valve timing. So it may not be less parts, other than the obvious cylinder count items.

 

I just think about how many F150 5.4's with that cam phaser going out had issues. Aftermarket now makes kits to lock out that phaser that was an issue.

Typical marketing people. Compare it to Ford's naturally aspirated 3.3L instead of Ford's own 2.7L turbo motor that happens to have better numbers.

That's because it is aimed at competing with the base V6 model from Ford.

 

Ford markets 2.7 EB as an alternative to its 5.0 V8, and of course Chevy's lower end V8 Silverado.

 

Chevy is pitching its 2.7 I4 as an alternative to its own base V6, and thus Ford's 3.3 V6 in a competitive sense.

 

It will be interesting to see what Ford does in response. The 3.3 V6 seems to be doing just ok in sales... not sure if offering a 2.3 EB I4 alternative will change the picture that much. But it should yield even better CAFE.

 

Edit: I think the appropriate response from Ford should be a 2.3 EB paired with 48V hybrid system... that will only add minimal weight but significant upside on MPG.

It is interesting how differently each carmaker is evolving their trucks, they all have some very different approaches.

 

Yes sir. Things will really get interesting once electrified powertrains in pickup trucks become common. FCA is already applying 48V mild hybrid technology to 2019 Ram.

 

The holy grail in the next few years will be plug-in hybrid or full electric pickup trucks with overall capability comparable to or better than gasoline or diesel trucks. I wonder if Tesla will be the first to deliver, or will it be one or more of the incumbents (Ford, GM, FCA, Nissan, or Toyota)?
