More Info on '05 GT\'06 Cobra

03CobraBro · Jul 1, 2003

We'll have to see... the prototype vert had the same power plant the 03 Cobra has weighed 2800lbs... Now that was with carbon fiber though. Iv been trying to guestimate, based off of 2800lbs prototype vert, what an alloy coupe with a cast iron block would weigh in at. Anyway I would say it would be lighter, atleast between 3300 to 3400lbs. Only reason lately iv become skeptical of how light the new stang will actually turn out to be is because of how heavy the Lincoln LS and the Jaguar S-type is... Then again those cars are hauling around a bunch of luxery equipment too.

With more modern safety regulations, the nice stereo the Mustang tends to get, the iron block the Cobra guys love, 4 seats, bulkier dohc engine with blower, etc...the car will be plenty heavy. Unless they use a full aluminum frame (not the lincoln frame) or a carbon fiber body (expect to add $30k to the price). It just isn't going to happen.

I spend a lot of my time at corvetteforums chating about the C6. Dave Hill (vette chief engineer) has a rep for being a Nazi when it come to weight and balance...and most of the respected guys there doubt he'll be able to pull much more than 100lbs out without aluminum frame (unlikely) or carbon fiber use everywhere (possible).

2800lbs was just a figure to create hype.

You must be joking that thing is pathetic...

I'd rather have a neon.....

06 Cobra, I should be able to have one of those too...

wtpSVTkh01 · Jul 14, 2003

does anyone have any idea what the price range will be for the cobra? also i heard the new engine for the c6 will start off with a little over 400hp or in the mid 400s.

I'm just speculating... but I would assume somewhere close to 40,000 simply due to the new platform setup.

wtpSVTkh01 · Jul 14, 2003

still cheaper than what the vette would probably be. sounds good to me

I also agree the Cobra will be in the $40k range. C6 Vette should run in the high 50's.

Most agree the C6 will have a 6.0 liter 425hp engine standard and will weight in right around 3000lbs. The performance version in 2006 will have a 6.3 liter 500hp engine with maybe 50 more pounds dropped. That's better than Murchielago power/wt ratio.

Obviously nothing is official yet, but that's the current evidence from some reputable sources.

Well I hope the new the vette does get all of that, that'ed be a pretty neat car to see.

As far as the murcielagos power to weight ratio... pretty much any car that weighs under 3700lbs and has more than 500hp puts the murci's power to weight to shame.

QuicksilverC5 · Jul 14, 2003

That's pretty much the established numbers by nearly all the automotive publications.

3700lbs and 500 hp would NOT compete with the Murchielago at all.

Just some rough numbers relative to the cars we're speaking of:
C5 3200lbs/315rwhp: 10.1 lb/hp
03 Cobra 3600lbs/360rwhp: 10.0 lb/hp
Z06 3100lbs/360rwhp: 8.6 lb/hp
Murchielago 3600lbs/480dyno hp: 7.5lb/hp (est about 18% loss since I couldn't find a Murch dyno)
C6 Base 3000lbs/380rwhp: 7.9 lb/hp
C6 Perf Version: 2950lbs/440rwhp: 6.7 lb/hp (est 12% drivetrain loss (same as C5))
Ferrari Enzo: 2770lbs/540rwhp: 5.1 lbs/hp

Hopefully that clears things up.

It was more or less a joke since the Murci seems quite the chunk for what its made out to be...

A person could say the same for the Cobra, but I'm not driving around in a cutting edge european sports car either, which is what the murci's supposed to be.

QuicksilverC5 · Jul 14, 2003

Cool, I just wanted to make sure you were ok.

cobra1 · Jul 14, 2003

The people with 03 cobras that are pulling 385rwhp are getting around 9.5lb/hp ( they are pretty close to the Z06 in performance). In the future the cobra will be around 7.7lb/hp ( assuming that it weighs 3300 pounds and it has 425rwhp with a 15% drivetrain loss). I think it will definitely be a competitor with the Z06, viper, and lambo in terms of acceleration.

cobra1 · Jul 15, 2003

QuicksilverC5, 3700 pounds and 500 horsepower would Definitely compete with the lambo. The lambo weighs over 4000 pounds! It makes 572hp and 479tq. With your estimated 18% drivetrain loss the lambo is pushing 8.65lb/hp. Remember the lambo is only running mid to high 11s (sometimes low 12s).

Are those guys pulling 385rwhp stock??? We can put a few grand into a C5 and pull 450rwhp, but then the endless stock vs modded discussion ensues. Either way, 9.5lb/hp is not near 8.6 lb/hp...sorry.

IF (that's a BIG if) the next Cobra can put out that much power (iron block?) and go on a big diet to 3300lb, it'll certainly be a contender in the acceleration dept with the regular C6. I'd take a good look at said car if it can drop lots of pounds. I only quote C6 figures since they seem to have leaked out already through reputable sources.

The lambo weighs a bit over 3600lbs, same as the 03 Cobra. I'm not sure where you're getting your info.:shrug: Trying to judge a Lambo by 1/4 times is pointless. At least quote trap speeds instead of et's. Et's have more to do with tires and driver than power in many cases. The Murch traps around 122, not bad for a stock car.

That is true. its not unheard of to see 03's dyno that rich in stock form. The richest one iv heard of was 392RWHP with the air silencer removed.

Typically 360RWHP is what they'll pull right off the lot, over the first couple thousand miles iv heard alot of guys noticing 15 to 20RWHP gains from simply breaking the car in.

QuicksilverC5 · Jul 15, 2003

Air silencer removed certainly isn't stock. That's like these guys who claim "stock" quarter times on DR's. Either way, the hierarchy above should be pretty clear.

Yeah, that's got to be worth at least 175rwhp.:lol1: Throw on a few type r stickers and I'll be at 1000hp in no time.:lol:
