Does an 8-cylinder sports car like a Camaro Z28 REALLY have better gas mileage than a 4-cylinder GMC Sonoma?

Question:
I'm getting these repsonses saying that the manuafacutres lied about the gas mileage and that it's too small of an engine to give good gas mileage to a truck that weighs 3,100 lbs.

What is pinion factor?



So with an 8-cylinder having 305 hp for a car that weighs 3,500 lbs., this means that I'd be getting like 25 MPG for the highway, as opposed top the Sonoma's 18 MPG, am I right?

Starter Problems?

gas mileage depends on the year but yes the camero probably does get better gas milage because of the power to weight ratio that it has. the camero's being 11:1 (hp:lbs) while the sonoma that probably weights about as much but only get around 150 hp out of the 4 banger which would give it 23:1 so you would be using more gas to get you truck going that the camero uses. Also depends on turning my dodge v-10 truck has about the same engine as the viper but the viper gets twice the gas mileage and more power even though they weight the about the same.

It is not so much the number of cylinders as it is their displacement.. is your 4 cylinder a 1600? what is the 8 cylinder?...

Carburetor?


It is quite common for 4 cylinders to get only 18 mpg (our PT Cruiser gets that)...

What would be the best!?!?!?!?


I'm not sure what the Z28 would get.. but you can probably search for specs on it online.

My friend had a C5 Corvette that had a 350 hp V8 and was rated at 20 mpg highway. My 190 hp V6 Toyota truck is rated at 19 mpg highway. Our actual mpg were very similar to the claimed mpg.
