Feeling C7 optimism, and some predictions...

As Roadkillz says, we get fewer of their engines and frequently, there are differences (tuning for less of certain emissions - read lower power most of the time) in the "same" engine that comes across the water.

BTW, to the best of my knowledge, the only thing that changes on the LS when a vette is shipped to Europe is the name / number of the power unit.
In England its:
1 Imperial unit of horsepower = 1.014 Metric - a small but not insignificant difference

Other countries tend to use Kilowatts rather than HP. Conversion tables are on the net.

What is the cost to bring an engine to the US market compared to the European market? I would figure it would be cheaper in the US due to lower standards.

My best guess as to why there are fewer engine options in US market vehicles is because A its cheaper to have fewer and B the smaller engines may not do as well in the US.

Thats the now-famous, or infamous, thread in which a newcomer to ls1tech, who claims to be an "advanced combustion engineer" at GM is giving out information. He has implied that the LT1 may make closer to 500hp, 600 for a z06 and 750+ for a forced induction ZR1.

He also claims the motors will self-tune and gain 40-80 hp on E85, and many other things.

I think my prediction of a standard C7 beating a C6Z at most performance metrics, right down to 'ring times, by the end of its run will hold up.

Also, if what he is saying is accurate, the world will look right past the origami of the rear end. And, remember, there is still hope that in real life the rear looks ok, or at least forgettable.

I think the C7 will be a hit.

Of course it will be a hit

With a really high compression ratio the use of E85 which is of higher octane then regular fuel (up to 105 octane) will result in more horsepower and torque.

though I am not sure on the other stuff, its possible that the base C7 will run a ring time faster then 7:22... just not likely.

I think alot of it is because Europeans pay a tax on engine size. Since we don't have that tax here coupled with the fact that they know American's don't want to be upstaged by their neighbor and will buy the 335i instead of the 325i because 35 has to better better than 25, right? Hence why spend money to certify an engine that you know will not sell here?

That is how i feel about the matter, they do not think the 320i will sell well in the us.

Hopefully the weight loss in the c7 will offset my weight gain of the last ten years!

I hear that tread mills are very effective for long term healthy weight loss.

I think about that sometimes when I read about radios being deleted to save weight (what is that, 2 pounds? 4?) and things like that.

I fluctuate between 185 and 210, depending on whether its winter and I'm lazy and going to 213 christmas and thanksgiving feasts, or summer when I tend to run outside. Does that mean my car is messed up in the winter?

What if one takes a friend for a ride? lol

This is FALSE. With DI knock isn't as much of an issue. Since the engine will run the same compression with gas and E85 it will not gain power. E85 has less energy than gasoline (about 30%) Octaine has ZERO to do with the amount of energy in fuel.

the self tuning stuff I can buy, Hptuners has suposedly been playing with this for a while internally. it still won't be perfect unless GM calibrates all of the MAF sensors for each car.

GMs flex fuel engines produce more horsepower on E85 then it does on regular gas. The LC9 engine (5.3L truck engine) produces 315BHP (on gas in the Silvarado) and it produces 326BHP (on E85) (SAE J1349 certified). So the 5.3L engine in the Silverado gains 11BHP and 13ft-lbs of torque when you run it with E85 compared to pump gas. The LC9 engine runs 9.6:1 compression ratio (no where near what the LT1 engine runs).

My prediction:

The C7 will have the shortest life span of any corvette (except the C2) and will sell the fewest number of units since 1984.

I hope you are right so we can get on to the C8, which I hope would be made for Corvette buyers.

There is no "timeless" look to the C7 Corvette design, and no tie to it's heritage. It's a been-there design with Nissan GTR sides and Ferrari / Aston Martin styling cues.

The car will look VERY dated very quickly, since this look was cool 5 years ago.

My biggest worry is that if the C7 Corvette doesn't hit the sales #'s, that there will not be a C8.

And Welburn & Peter's will forever be remembered as the guys that killed the Corvette. I remember Welburn voicing his concerns about just that, in an interview sometime ago.

I guess we're about to find out.
