Was looking to possibly buy a Shelby

Right, and but that doesn't mean you WANT to afford it. It's like saying "You make $250K a year gross, why worry about $50K in taxes to support welfare?" **** that.

Ability and want are two separate things.

Well my last road trip, 4 hours, I got just under 25MPG in my 400whp SC 370z doing an average of 85mph so I think the Z is fine.

Wow...fail comparison.

How is it a fail comparison?

Paying for welfare annoys me almost as much as a $1000+ transmission fluid swap would. (I wish I made $250K, or I could be having this discussion on a Ferrari forum, but sadly, lol)

Also, sounds like my 7.0 is rather efficient.

theDreamer

The argument of the 7.0 is because it skips gears to create its fuel efficency and has to make sacrifices to reach those MPG. I drove hard in the city last week and still hit 20MPG, and by hard I mean never shifting before 4k and haivng a lot of fun runs with friends.

I know it's not a 7.0, but my 5.7 had the same feature, and I never used it. I still got over published mileage in the city, and that car was over 100K miles old. I am willing to bet my Z06 would get well over 16mpg in the city without using it, too. Actually, the skip-shift feature is VERY unobtrusive on the Z06. I hardly ever run into it. I shift before I reach the rpm window usually and it still accelerates nicely.

youe point makes no sense, the car is geared for a car with 500hp. the car in 4th gear at 25mph has more power than your car in 2nd

theDreamer

Highly doubt that since I have a SC 370z and I know what a C6 Z06 can do in 2nd gear.
The point of the post was the car makes sacrifices to achieve fuel economy. I am saying not that is a huge negative (would love to have a LS7) but it has to do something to achieve its higher MPG which keeps it out of the gas guzzler field. Maybe GM should have invested in making a more modern engine instead of focusing on just larger displacement with its latest LS motors.

2011 GTR combined fuel mileage is 17 (15-21). Z06 is 18 (15-24). ZR1 is 16 (14-20). I don't care what technology it has, it is still pretty impressive given what it can do. The skip shift is just a way to fool the CAFE test, not much different than an automatic transmission locking its converter. The gear on the C6 is built for track, it has the power to back it up. It's the same reason why the 370 has taller gear than the 350. If you put gears from a Civic in a Corvette, you will just spin tires and make pointless shifts. If anything, Chevy is smart to have an engine that can develop power from basically 2000 to 6500. I don't get why these threads always become hate threads. Most of the Corvette guys think they have the best car and all the Japanese drivers think they have the best car. It's ignorant. Is it that hard to respect one another's car and choice.

Maybe you should show me another engine that makes the same (or more) horsepower and gets the same (or better) economy.

The LS7 is just fine. It weighs around 450#, makes 505bhp, and will get 26mpg on the freeway in my experience.

Oh, it has a 5/100K mile warranty, too.

Go find me this "modern" engine that can equal that for $15K.

It doesn't exist.


Did you actually do any research on why the corvette has the engine that it does?

Have you actually compared the physical weight of the LS series engines (about 450#) to their competitors? Have you compared mileage? Have you compared power under the curve?

Noone gives a damn about displacement, it's a means to an end. What designers care about is power/weight, and the LS-series engines are KING in that department. Compare them to any N/A engine out there and you will find that the only one's that better them in physical power/weight cost roughly $50K and are found in AMG's. The LS7 costs $14K.

Now you bitch about mileage. Bring up skip-shift. Bring up all that crap.

Well why don't you go look at a 'vette with an LS3 and a slush-box? It gets 1mpg less in the city than the stick. It has no CAGS. It has an efficiency-robbing hydraulic tq converter.

CAGs. It's not doing all that you think it is.

Just because the LS3 and LS7 use old concepts does not mean that they are not cutting edge engines. Your tires are still round and all that. Doesn't mean the rubber around the rim is as old a design as the wheel-shape, if you get the drift.

you might want to check your figures, the countrys biggest expendutire is in the military.
