Know.Car and Driver tested an LFA 0-150 mph. It did the trick in an impressive 18.4 seconds off an 11.7 @ 125 mph 1/4.
CD ran the Z06 through the same standardized 0-150 mph test. The result was 17 seconds off an 11.6 @ 126 mph 1/4.
Motor Trend staged a 2011 Best Driver's Car Competition which saw the LFA, R8 GT and others face off against the Z06 at Laguna Seca. The Z06 was a staggering 2 seconds a lap faster than both the LFA and the R8 GT.
Given Laguna Seca's 2.238 mile length and the known difference in lap times the math indicates that the Z06 was some 17 car lengths away when the LFA and R8 GT made it across the line.
Btw, you might find pro race driver Randy Pobst's comments at the link above on the handling issues plaguing both the LFA and the R8 instructive. The Z06 still holds Motor Trend's lap record for a Best Driver's car contender. A number of its opponents, like the LFA, R8 GT and Ferrari 458 have far more horsepower than the Z06. Turns out it takes more than a horsepower rating to win races.
Finally, Car and Driver periodically stages a Lightning Lap competition at VIR. The 525 hp $171,600 as tested V10 R8 5.2 put up a 2:59.5. Not bad at all. Anytime you get below the 3 minute mark you are doing well. Which puts the Corvette's 2:58.5 in perspective doesn't it? Did I mention that that time was put up not by the Z06 but by the $57,310 as tested, 436 hp Grand Sport? Yeah, that. You don't even want to know what the Z06 did.
Trust me.
Again, there is more to a performance car than its horsepower rating. Case in point, compare Randy Pobst's comments in MT as to why they R8 was slow to what Car and Driver said about the problems with the R8's performance in their Lightning Lap test. See any similarities?
Before you go pointing to the Z06's hp rating I would point you to the LFA's $375,875 base price and wonder if you think it is fair or even logical to compare the performance envelope of a ~$50K base price car to one that starts at just over $375K before options. In NY, the 8.75% sales tax alone on a $375,000 car is $32,812. Compare that to the known base price of a Corvette. A comparison with an LFA is simply illogical on multiple levels. That there is a Vette (and not even the top one at that) at a fraction of its price that can in fact dispatch it with ease is a thing of beauty.
The upcoming base Corvette will be first compared to Porsche's 400 hp 911S which is its natural enemy. The LFA, a basically DOA car, if it is still being produced will be compared to the next Z06 and/or the next ZR1. Not the base Corvette.

And as much as I love my 800+ hp C5, it is a weekend toy only. Not a daily driver. I've already stated in another post in this subforum, that if the base C7 was in the 2900-3000 lb range, and 450-480hp, it would be a homerun among home-runs. But I unfortunately don't see the number hitting 3,000 lbs, let alone under.

And if the C7 comes in at 3050 lbs (very easy to accomplish with 136 pound savings with an aluminum frame, another 10 pounds with the Mg engine cradle, and 10 pound savings with the carbon fiber/balsa wood floors), then 450 HP will also get you 6.8:1. Even easier to realize 21 city/30 hwy with 450 HP lugging around 3050 lbs, then 470 HP lugging around 3200 pounds.
Now we wait for the curb weight. To ge to the Weight to HP ratio of 6.8, they will need to shave off exactly 119 lbs from the Base C6 curb weight of 3179.

I must've missed that dyno sheet. There is certainly no confirmed numbers yet. It is only estimated at 450...and I believe it will certainly be higher than that.
You're jumping the gun with that statement.

I have an ebay account and I've googled as much as I can -- but I can't seem to gauge a value on these things -- only seeing that brand new ones are close to 5 grand. Does anybody know the value of these things? I'm a motivated seller because I have absolutely no use for them... but I was hoping that somebody could shed some light on them.
Please help! Thanks[/QUOTE]
I think it will weigh 167 pounds and displace 312 cc's. And, it will produce 1000 RWH at 57 RPM with 6000 pound-feet of torque.
Oh yeah, it will also get 89 miles per gallon.

Actually, no one outside of GM knows how much hp the base C7 will have. Including the reading challenged on this forum. Here is quote from the GM C7 press release: "450+ horsepower. Final number released at introduction of Corvette."

"Zero-to-60 mph performance for the new base Corvette is expected to be under 4 seconds. Efficiency is increased, making this one of the most fuel efficient 450-hp vehicles available. That’s right, an estimated 450 horsepower at 6000 rpm and 450 lb-ft of torque at 4000 rpm."
"In addition to the estimated 450 horsepower and 450 lb-ft of torque, Chevy is also predicting 26 mpg."
Notice they say "estimated 450 HP" not a "minimum" of 450 HP. I would think that if GM was "estimating" that the horsepower would be 475 or 480 or ???? then they would have said "estimated 475 HP" or "estimated 480 HP" or "estimated ???HP", not "estimated 450 HP".
While the final SAE certified horsepower might be slightly different from the 450 Hp GM has estimated, it won't be by much. GM estimated the 2006 Z06 would be 500 Hp...it was SAE certified at 505 Hp. The CTS-V LSa was estimated at 550 HP and was SAE certified at 556 HP.
Anyway Tadge was quoted as saying....
"The Holy Grail for developing a performance car is delivering greater performance and more power with greater fuel economy and that's what we've achieved," said Tadge Juechter, Corvette chief engineer. "By leveraging technology, we are able to get more out of every drop of gasoline and because of that we expect the new Corvette will be the most fuel-efficient 450 horsepower car on the market."
That was in the GM press release. Most of the magazine articles have embellished the press release by adding their own personal beliefs on what the horsepower MIGHT be.

Of course it is a PowerPoint chart not a dyno the line placements may not be accurate.

Actually you can look at the chart and see if the reported horsepower matches the reported torque. Horsepower is not measured, it is derived from the torque and RPM. I did that and got ~460 HP at 65-6600rpm.

HAHA... I wonder how close I actually came. Torque is on the money. I sure do hope the HP number is right too. I won't be too disappointed if it's closer to 455-460, but 475 is a number I don't think any manufacturer has used yet.
