Why Bother? Chevrolet Debuts Turbocharged 4 Cylinder Silverado - Gains 2 MPG Over V8

That’s a 9.5% savings in fuel consumption (15% in city only consumption). Multiply that by dozens, if not hundreds, in a fleet and that is a business savings that helps the bottom line.

Jeffgall: Kudos to you for doing the math in comparing the fuel CONSUMED, rather than just looking at a small “2” or “3” difference in MPG, and incorrectly concluding it’s insignificant.

Combined (9.5% savings)
19 MPG = 5.26 gallons/100 miles (baseline)
21 MPG = 4.76 gallons/100 miles

City (15% savings)
17 MPG = 5.88 gallons/100 miles (baseline)
20 MPG = 5.00 gallons/100 miles

I went from a V8 f150 to a turbo6 Ecoboost... no gain in real world driving at all. i expect these numbers to also be non real world. VW is not the only one playing games with MPG

The Ecoboost Fusion gets the same or LOWER real world MPG as the old 2.5 4.

does it require 93 octane vs. 87 for the V8? Ifso doesn't that equate to higher running costs?.....

GM Blew it on this one

IF the 4 cylinder had come in quite a bit better in mileage than this - they might have had a case for it - BUT - at these numbers - it was not worth the trouble - that engine belongs in a Colorado - and I believe that is where it will end up

I can see these engines having problems down the road hence why Ford is using a V6 to turbocharge NOT a 4 cylinder as you have to really really work that 4 cylinder and in a truck that's a lot of working it needs to do. Mind you this is all besides the fact that GM cant make anything reliable.

Nonsense - GM has made LOTS of auto parts that are so reliable that they have been used in high end exotic and luxury cars around the world - among them Rolls Royce - Bentley - Mercedes - and BMW.

And GM full size pick up trucks are also at the head of the list of longest lasting vehicles on the road.

THe problem with the 4 Cylinder is perception - people assume 4 cylinder engines to be "smaller" and will have to work harder - yet they have used 4 cylinder Diesel engines for decades without such complaints. This is not a "small" engine and likely will last a long time. The problem here is that the 4 cylinder does not offer higher fuel mileage over older designs of larger engines.

The engine failures will be epic on this one if the truck is used regularly for hauling or towing. The little engine will be huffing and puffing 24-7.

I won't notice the little 4 cylinder banger when descending long, steep hills.
