Anyone else disappointed with a "New" engine that is heavier with only 14hp and 22lb-ft more than the current LS3?

Many threads on this already.

Final numbers are not announced yet, they will be with the C7. Lets stop jumping to conclusions about a car based on a motor architecture announcement.

Low end torque numbers are as much as +50tq higher then the LS3, this will be an absolute kick in the pants... but hey lets look at peak numbers only. :rollseyes:

And don't forget cylinder deactivation, so yes.

Landru

So far not enough info; although, on a similar thread I made a crack the C7 better be great if it's to best the LS-7. From what we know HP #s may be very close to LS-7, and the C7 projected to be [significantly?] lighter. Will be interesting, not disappointing.

So, spoil your plans to buy one?

The most disappointing thing for me are people posting negative comments about something they know very little about.

Actually it's better than I expected. Bottom line will be how does the car perform. Lap times, 1/4 mile etc. If it outperforms the C6 with the new interior etc it will be a hit.

OK, I fell into the same trap by looking at the peak numbers initially and poo poo'ed the motor too. But look at the dyno print compared to an LS3, the average power and torque on this thing is head and shoulders above the LS3. You're only at peak power for a second, so this thing will perform like it has a lot more. Not to mention all that torque for low RPM day to day driving... It'll feel like a monster. And thats with a cam that's smaller than the LS3 cam. When the aftermarket catches up, do a cam swap and you'll have a hell of a performer.

The comments in these C7 threads are some of the most ridiculous comments i have ever seen.

You know nothing more than only a few HP/TQ more and a little heavier. Such senseless comments. Wait till it comes out, and as stated look at the dyno graph there is much more that only an increase in TQ/HP the power band is much, much, better.


^Thank you as I was writing this you posed up a dyno graph! haha

I'm obviously willing to (and having to) wait until more final info is released, but I will say that if 450 hp does end up being the actual power figure, then unless there are some awesome revelations about the C7 in terms of weight, chassis upgrades, pricing, other features, etc, I probably will completely lose interest in this car.

EDIT: And yes I understand the benefits of an improved torque curve and whatnot. That's still not enough power.

LS1LT1

absolutely.

CaryBob

Not enough for what purpose? Surely it will outperform anything in its price class. As a daily driver and occasional road course car, it shoukd be pretty decent. And the ZR1 version shoukd be a real winner.

How much heavier is it?

ctusser

Since you're coming from the perspective of an 07 Lexus IS, 450+hp/tq must be a downer

copied here with no commentary. just to indicate how far we have come and the potential of this platform...

I don't know why people keep bringing up higher end models. Even the base model should have more power than that. By "not enough", I mostly mean relative to my expectations of a next gen Corvette. It's also a bit underwhelming relative to value-priced performance cars in other classes. Obviously this thing will outrun any of those cars around a track, but it just leaves you with the feeling that they should have been capable of getting more juice into that motor.

I might just buy one of the remaining C6's on a dealer lot on the cheap if the final figures aren't better. Why spend 50% more for ~5% more performance?


Well of course it'll be faster than my car. What's your point? I fully expect it to be... I just expected it to be even faster. Besides which, at ~320 bhp (after a couple minor mods), my car isn't THAT far behind. It's not like I'm coming from a Prius or something.

At 465 pounds, it's ~30 pounds heavier then the LS3, or ~20 pounds heavier then the LS7.

Jinx

Imagine what stump-pullers GM's pickups are going to be when they get their version of this engine.

And even Escalades will feel quick.

JoesC5

Of course, GM had to leave a little on the table with the entry level engine in the entry level Corvette. That leaves them more to give you in an optional high-performance version of the C7.

Sure, you can purchase a left over C6 for a lot less then a new C7 will sell for in the first few months of production, but the MSRP of the new C7 will be very close to the MSRP of the outgoing 2013.
