C5 vs. C6 power to weight ratio comparision..including Z06!
power to weight comparision


C5 weight 3240 lbs/ 350 hp........ 9.257
zo6 weight 3118/385hp............. 8.098
zo6 weight 3118/405hp............. 7.698

Most airbox exhaust C5's
weight 3240lbs/370-380hp.......... 8.756


C6 weight 2900 lbs/370hp........... 7.837
C6 weight 2900lbs/400hp ............... 7.250
C6 weight 3000lbs/370hp........... 8.108

C6 ZO6 weight 2800lbs/450hp..... 6.222
C6ZO6 weight 2900lbs/450hp...... 6.444

Viper weight 3400lb/450hp........... 7.555
or 2003 Viper..
Viper weight 3200lbs/500hp......... . 6.400

this is the power to weight variation proposals I have heard on the various forums for the C6, the c6 zo6 and the 2003 viper scheduled for production.

Of course torque and gearing come into play as well but I think the comparision is interesting..

MY question is....Do you think the C6 standard version will come in weighing under 2900lbs?

or closer to the 3100 of todays ZO6...

or 3200 of todays C5?

Wow!! Cool post JB. Really excellent comparisons. My guess is closer to the 2900 is the C6. Without a doubt the commitment is there for a Viper killer. Hands down your going to see the finest built US sports car the world has ever seen. No doubt in my mind.

Now all we have to do is hope that they keep it in the same price range as the current car and put the real engine in a coupe and vert.

If you can't get the 450 hp engine in anything except the FRC I won't be buying any more Corvette's.

Great post, JB!!!

Love those numbers. Let's hope the weight of the C6 is significantly lower. However, I've heard that the primary chassis/platform will not change. And, since more than 50% of the total weight of the car resides in the chassis, I'm just not sure.

Since you posted Viper Killers, I just had to include this one:

2002 GTR: 2310lbs @ 500hp = 4.62 p:w ratio

Sorry, I just had too.

I wonder if it wouldn't be better to compare TORQUE to weight ratio, as torque is what is accelerating the car? Also, the broader the torque curve, the more favorable the acceleration.

For a simplified analysis, it works though. Hope for the best. Of course, there is no reason to wait for C6. Do some work to your C5 to get 500 or more HP and you have yourself a nice beast to enjoy while you wait.

There are a lot of variables for sure...

I would say..I followed the practice of most magazines on this quick summary of hp to weight..

If you know the torque ratings off hand..I'd be interested as well..

I'm betting stock base C6..will run 370hp up about 20 from todays C5..so that should give you a decent number to work with for torque computation..

Gearing plays a big part as well ..

Just shooting the breeze on it..

As far as speed goes..the stock C5 will do 170mph..and do 0 to 60mph in under 5 seconds..LOL

8.018 for the C6 @ 3000 lbs and 370hp and 8.098 for the 2001 ZO6

That looks like a fine comparision number to me!

That was and is world class..


IF it comes in under 3000 lbs..it gets even better..

C6 will be a winner..

BTW..Mr. Fido..that power to weight ratio makes 450 hp..not necessary to have the top dog in my mind..

You know you will always have a corvette for its beautiful lines as well as its awesome performance..

Does a car body design get any more beautiful than Corvette?

Once you drive a car as beautiful as this..your spoiled..you can never go back to the more mundane!

JMO..lol

have a good one!

JB

Redshift, is on to something here.

Maybe you can use a composite of the two given the diminished impact of Torque long-term; to get an even blend that shows good overall performance.

I'm looking at one of my latest dyno sheets and it shows the intersection to be right at 5,200rpms.

From that point the car loses 44 foot-pounds in just 800 rpm's! This is equal to a ratio of 18.18 ft.lbs/rpm. The horsepower barely drops in comparison to Torque after 5,200 rpm's.

So, how about using Torque to Weight Ratio up the Intersection of Max Torque & Max Horsepower. Then use Horsepower to Weight Ratio. Finally, take the sum of both ratios and divide that dividend by 2, to obtain a blended performance figure for power.


It might look like this:

BP ~ TWR + HWR / 2

(where BP = Blended Performance, TWR = Torque to Weight Ratio and HWR = Horsepower to Weight Ratio)

Just a thought?

I'll say it one last time and plan on telling Lutz when I see him at Detroit that we don't want some watered down BS performance in our coupes and roadsters. Give us power and handling or some of us will be spending our sport car $$$$ elsewhere!

All Corvette's should have the 450 hp - 450 TQ optional engine and performance goodies!

Fido..you don't even go past 65mph..what are you talking about..

LOL..

I'm kidding of course but believe me..370 hp in a 3000 lb corvette will be awesome..

I wouldn't sweat that 450hp..but thats me..

If I could get the performance of a world renouned sports car like the 2001 zo6....

as the base model..thats pretty dam cool..


I do think you will see a 450hp motor available across the board.....

The zo6 fRC thing was to save the tooling costs..imho..that was originally supposed to be the C5 billy bob..but sales were and are too strong for the C5 line to warrant a less expensive model..So they made it the fastest most sought after from a performance perspective..

Not fact..just my opinion..no flames to the zo6 crowd..I love the car..but understand the desire to let the sun shine in as well..

Especially in sunny california!!!

Fido..you tell Bob..what you want! You'll get it!

Keep the faith! B/c its coming!

BTw..tell him JB wants sequential shifters..LOL..(Just kidding! )
