Hello forum,

I hope this is the right place for this.

There is something I have been talking about for awhile concerning fuel milage with these new cars. It's actually two stories I geuss.

I used to have a 78 Camaro. It had a 2.41 gear and an automatic. I built a 350 for it with aluminum corvette heads, decked the block so it came out to about 11:1 cpmpession. Factory exhaust manifolds. After it was run awhile I put in a factory blueprint 350HP 350 cam and it got better gas milage.

The gas milage was 22MPG. I am not a hard driver when I'm not goofing off but this was with no computer or overdrive and that was not the lightest car by any means.

At the same time my freind rebuilt the staight six for his 70 chevy pick up. It had some kind of performance cam in it headeers with dual outlet and a three speed standard. He came across a overdrive tranny and after putting that in he claimed he could get 27MPG with it if he drove it easy. I can not swear to this but he has no reason to lie and I have ridden in the truck and seen that it did not use much gas for the distances we drove.

We are not engineers or professional engine builders.

I would think that with computers, overdrive and all of this technology it would seem like the newer cars of any size should be getting about 30MPG.

Yes the new Corvettes have more power than my camaro and get the same or better gas milage than I did but what about all of these little cars. I think I have seen these econo cars rated at high 20's to low 30's but they are smaller, lighter and not near the power my car had.

Sorry to ramble on but I have been wondering if maybe we are getting all we can out of the internal compustion engine and the only alternative is another power source for cars.

Thanks,
DonDon

I think alot of people have gotten in the 30mpg range with 4th gen LS1s.

I have a cam/heads/headers/3.73gear/4400stall in my 98 Camaro LS1 and last time I had it out I got 18mpg avg on the interstate and I punched it about 3 times during that time:D

Yeah, my 2001 Z28 with the 2.73 gears routinely got 29-30MPG on the highway (when it was stock).
Before this car, I had 2 V6 (3.8) Camaros, and they routinely got 32-33MPG on the highway.

I'm hoping for better numbers out of a 5th Gen.

I currently have a 2006 Honda Civic coupe auto. I get combined hwy/city between 26 - 29 mpg. This is a 2800lb car with a 140 hp but its high revving to 6800 rpm. If the new Camaro with the V8 can get 30 mpg on the hwy and 20 in the city with a combo of approx 24, on regular gas "sign me up". :patriot:

I did not know that the camaro's or any V8 was getting that much milage. What were the 4th gen's rated at, do they get better than advertised.

Like I said about the smaller cars not getting much more than I was I think I remembered the older Miata's rated at 27 highway and it seemed rediculous compared to the bigger cars at that time.

So I can look forward to a new Camaro that will beat the tar out of my old one and get killer gas milage.

Thanks for the responses,
DonDon

GM V8s normally get better than advertised when on the highway.

I noticed that what ever they rate them at expect them to have slightly less than that at the rear wheels.

LS1 Camaro rated 305HP If I recall correctly most dyno with around 290's RWHP.

1994 Corvette LT1, 6 speed. Average (around town, autocrossing, barely any highway), 22 mpg. On the highway, the instant mpg reader averages 35 in 6th gear.

Hell, I bought a 1984 Vette in 1995 with 40,000 miles and on the drive back from Dallas I averaged 36 mpg.







Yep, 1984 was a Crossfire.






With the 3+4 Manual.

I've seen 28 out of my ragtop SS. Back when I had a 98 V6 camaro it gave me 32.

This is what I have been wondering about. The figures you have been listing here makes me wonder what the problem is with people wanting more.

Maybe I think these are good figures and others don't.

Maybe everyone should just drive Camaros.

General public = give an inch and they'll take a mile.

I know a guy with a 5spd 3.5l Colorado that claims to get over 40mpg highway (he once said the MPG on the DIC hit 50). This is with 4wd Z71, too.

Stock I routinely got combined (3/4 highway) 26-30 mpg with an auto 2.73 geared car. Dad claims he got 32/33 ish when he drove it to Nashville. I got about 21/22 with a big cam, headers, 3600 stall and 4.11 gears.

With this 03 Dakota 4x4 w/the "new" 4.7 v-8 local I get 13-15, highway I get 22. Now this new 4.7 was suppose to get better mileage:lol:. My 98 Dakota 4x4 w/the old 5.2 v-8, local I was getting a solid 18 local, 25 highway. So the way I look at it no matter what chevy does with the Camaro it's bound to get a lot better mileage the the dodge.
