There is certainly a very similar basic architecture between the Ford GT's 5.4L and the older GT500's 5.4L as well as the new one's 5.8L, but I don't think they're identical.
Interestingly, the new GT500 exceeds the output of the Ford GT's engine by A LOT.





Yes that part is true, it is an almost entirely forged bottom end. Those GT500 engines (as well as the older 2003/2004 Mustang Cobra engines) can make some CRAZY power on their stock internals (ie: without even opening up the engine) with aftermarket blowers, turbo conversions etc.

Im not too worried about the gt500's perforance. The camaro zl1 set a 7:42 lap time at the ring. The zo6 7:23, and zr1 7:19. The gt500? No time, and theyve been testing there. If the 500 did a time close to the zl1 they would have posted it, for sure. And being worried about some mustang being faster at a light is no new thing. There is alot of those mustang guys modding there stangs and blowing the doors off our zo6's. Theres nothing new here with that. And also i watched a dyno video of the new stock gt500 making 606 at the rear wheels. Im willing to bet a $100 that the $67,000 mustang wont even hang with the zl1 at a track. If it does not hang with the zl1, why are we, corvette guys worried??

I have been blessed to own 5 Vettes and 14 Porsches plus a few other cool cars. I always begin selecting my choices of sports cars by how the car looks. If it looks really good, it can pull me away from my current sports car. I then look at the overall performance & gas mileage. I used to drive AMGs but when the C-63 AMG only got 11 MPG in the city it didn't matter what it looked like or performed like. I was done with a car that was that much of a gas hog.
The new GT-500 is very impressive but it is a bit bulky for me.
I have been studying the performance numbers and I am definitely impressed. The interior is also much improved over the Mustang GT.
The new C7 will have to look good both inside and out. Right now the only thing we have to go by on the outside is very scary and dissappointing. However I am going to keep the faith that it will look great when it comes out. If the power is down around 450-460 hp, I can almost bet that I will go elsewhere for my C6 replacement. My brother just ordered the SRT Viper, his cost was above 135K. Wow!!!
The C7 needs at least 480 hp and an improved interior with lighter weight or there is other cars to seek after. My current C6 w/430 hp has been a fantastic car but I personnally need more power, plain and simple. Like most of you gentlemen, I want the best and most reasonable deal. I am confident that the C7 will keep us happy. But if not, I will go test drive the GT-500 & Jaguar, 991, etc.
It is great to have options.
Cheers!!!

Is it really THAT much money?
I was hoping that it would come in at around only $110k.
What is the actual MSRP on both Viper models (base and GTS) if you know?






What if it has 'only' 460hp but also performs nearly as well as a C6 Z06 (not likely of course, but possible)?
Is it ONLY the horsepower rating that you're focused/fixated on or is it the car's bottom line speed capabilities.
I've run multiple 10 second passes with only 393rwhp (maybe 450hp at the crank?) in my C6 LS2 so there's more than solely power ratings that make a car fast or not.
I wouldn't get so hung up on horsepower/torque numbers alone.

thebrander

I've been very curious about this as well. It seems like Ford would be VERY loud about it if it were lapping faster than the ZL1 or Z06. I'd LOVE to have a good reason to trade the C6Z in, but Ford is giving me nothing.

shawnvettefan

How about 470-480 HP/TQ with DCT and about 100 lbs. lighter? This will be sweet imo.

SanDiegoBert

My guess is lighter, but no DCT . . . I can see that HP, but with a smaller displacement, less TQ. Guesses, only.

LS1LT1

We can only hope/pray.
Depending on gearing and suspension tuning (ie: tire traction/launch control etc.) that combo COULD probably generate 'C6 Z06 level' straight line performance.

Jinx

Which Jaguar has a better power/weight ratio than 450hp/3100lbs?

Which 911, the Carerra S? If you're willing to spend for something other than power/weight, why have you written off C7 already? And if you're willing to wait for the 991 Turbo and spend that much, why is the next Z06/ZR1 not up for equal consideration?

It ain't gonna happen!

Lots of BS flying!!!!

Go to the Ford website and check out the specs for the new Shellby GT500 650hp for $55k. 5.8L supercharged (and so far every 2012 I've seen has been marked up $5k to $7 over MSRP.

But specs are.
fuel economy TBD
Compression ratio TBD
bore and stroke TBD
Valve lifter type TBD
fuel delivery TBD
recommend fuel TBD
exhaust TBD
Suspension TBD
Brakes TBD
Stability control TBD
steering TBD

Weight, they don't have a category for weight for any model Mustang.??

If this car is in production how is they don't know?

As far as comparing to Vette, like said most cars will never track, and even if tracked the new Shelby with a live rear axle will not handle as well as a Camaro ZL1 let alone a Corvette.

also on the street there are many more opportunities to enjoy a good handling car then there are to play with horse power.

As long as the handling also improves on the next Corvette all it needs at the base level is 450 to 475hp to still be more fun than a Mustang or Camaro.

And who knows, maybe right off they will have an option package with Mag suspension, better brakes, and a supercharged to 600hp for a decent price.

jackhall99

As in 'there are other cars to look at.'

If you need more power, add an Edelbrock E-Force Supercharger and get 554 HP for $7,500. Add a great interior for another $7,500. On top of the $42,000 C6 price (the car is readily available for that, plus taxes and fees), you now have invested $57,000 that will smash the crap out of any Jag available, and any Porsche this side of $200K.

Or go buy another Porsche, which is also a great car.

Those motors in the GTs were under-rated quite a bit I have seen several putting down 520-550 at the wheels.

jackhall99

This will be a miracle if it happens. I'm not saying a bit of weight reduction is not possible, but the Corvette coupe is still one of the lightest 'livable' sports cars on the road today. A few selected 'flyweights' are:

1. Lotus Evora – 3,047 #
2. Porsche Carrera – 3,075 #
3. Mazda Miata – 3,078 #
4. C6 coupe – 3,208 #
5. Nissan 370Z - 3,245 #
6. Lexus LFA – 3,263 #
6. BMW Z-4 4 cyl. - 3,263 #
8. M-B SLK - 3,308 #
9. BMW Z-4 6 cyl. - 3,494 #

Everything else (Jags, Ferraris, GTR, etc.) are heavier. It will be interesting to see what we get.

LS1LT1

Good points/questions.





True, and the 2013 GT500 is putting down between 590 and 620+ at the wheels.

Jinx

Time out -- where the heck did this number come from? That's high even if you weigh it with two of the largest people who will fit in a Miata.

From MazdaUsa.com --

The MX-5 curb weight starts at 2447 lbs; the loaded Grand Touring with the automatic, 2542 lbs. I think it gets over 2600 lbs with the hardtop. It's still the only car worthy of the term "flyweight" on your list.

OnPoint

It might have been hauling spares for the Lotus.

jackhall99

Oops. Hey, one **** up out of nine ain't bad my friend.

I grabbed gross vs. curb weight. 2,480 # is current curb weight. That doesn't change what I posted about amigo.

ps- I used Edmunds for quick specs. Beats going to individual car sites.

JerriVette

If the C6 weighs in at 3208 and then any of us dump the runflats...that should drop the weight by......around 24 lbs...(thats what the C5 Z06 saved in non runflat tires compared to the C5 coupe runflats...)

The C6 is already 3178lbs...which is dam impressive considering it has 436hp 428 lb/ft of torque .... stock..

I enjoy my M6 C6 Z51 1lt a lot...and I look forward to the slightly lighter more powerful (hopefully over 470hp direct injection Gen 5 V8)

I'm sure its going to be the best vette yet...and each year the C7 I am sure will continue to evolve with higher performance versions...

Cool list of curb weights...thanks for the info.
