Pretty Quick, if you ask me. Thought some of you might find it interesting as the performance numbers are fairly close to the ZR1. Are the numbers real? Who knows.

Sorry for the double post - I was trying to correct a spelling error and I couldn't delete the first thread - if anyone knows how, please let me know.

I believe those numbers. Can't wait to see the C7Z's and C7ZR's topple them.

CrystalRedMetal ZR-1

While those times might have been accomplished -- I don't believe the claimed specs of the car. If they did in-fact achieve those times, then the manufacturer is not accurately representing the car's power. How would this make any sense? 562 hp (much less than a ZR1), pulling 3400 lbs of weight (more than a ZR1), and getting 134 mph trap speeds? (higher than average ZR1) Where does it pull the top-end from? I think the specs were fudged or something, but that's just me. Who knows, maybe this thing's gearing is god-like, but I will be skeptical until more info surfaces. Would love to see a dyno also. :P

At the very least, under-rated power. I'd say likely a tad over 600...

I don't see that happening unless GM makes major changes to its drive train. To the extent you can believe anything, this is a car weighing 3,400 pounds and having 548 HP, yet having about the same or perhaps better performance than the ZR1.

I think they are going to have two on the show supercars next week. should give some "real Life" numbers if that show isn't bought off. They are makeing the whole show on the F458 so???? Tanner Foust and Paul Tracy don't hold back on thrashing the cars so makes for good T.V.

JBHunter

The 458 has an all new double-clutch transmission that is much improved over the previous offering. It will shift in almost "no-time" flat...first time that phrase has been used literally...

The best driver shifting a ZR1 6spd manual transmission would not be able to match gear changes in a quarter mile drag race with the stock set up.

The announced times for the Ferrari 458 are likely true and repeatable by far more public drivers than 10:80 sec E.T. runs done by the quickest drivers in the stock ZR1...my opinion...

BUT...The 458 Italia is approximately $240,000...for that you can have a ZR1, a V8 Camaro, a Chevy Pickup truck...(115, + 40 + 30) and a pair of Harleys (50k more) ...to help keep America ticking...

Enjoy all the NEW toys...or 1 new Ferrari...

Yes the transmission I believe. Tanner Foust is a joke.

The guy gets the burn the wheels off just about any car he wants. And somehow put himself in a place to get paid to do it. I'll take that gig.

Not saying I wish I where him, just would like to do what he does.

Tightly spaced 7 speed dual clutch gearbox with lightning fast shifts will keep the car in its sweet spot on the torque curve.....same way that the 500 HP 2010 997 Turbo will give a much more powerful ZR1 a run for its money....

chrisducati

Let's summarize as to why the 458 could be quicker than the ZR1 even with an inferior power to weight ratio:

1) Effective launch control combined with the engine over the drive wheels. (Yes, 2010 ZR1 has launch control, but still challenged with front engine/rear drive).

2) Dual clutch gearbox and super fast shifts as noted by another post.

3) Much lower gearing--all Corvettes, including ZR1, are geared very tall.

I currently own a Nissan GTR, ZR1, and Audi R8 V10. All great cars--IMHO it is neck and neck between the GTR and ZR1 for #1 value in the supercar market. As another post says, $250K buys you a bunch of cool stuff.

The 7 speed dual clutch may help lower the ETs, but the trap speed shows the power the car is making. I just dont see how a 560hp car can trap at 134 mph.

Tuned nissan gtrs that run high 10s, with a dual clutch transmission trap between 128 and 132 and they are making 550 at the wheels.

chrisducati

You've got a great point on the trap speed. 134 must be a road test record outside of a Veyron and would indicate big power.

BluegrassMotorsport

Anymore of them caught on fire yet?

vette6799

And how does that relate to the speeds of the 458? Please don't hijack the thread because you have an axe to grind with Ferrari.

Guibo

The GT-Rs and Corvettes have taller gearing. For example, at 100 mph, the ZR1 and GT-R are pushing 4.14-4.63:1 overall ratios, while the 458 will be pushing a 6.63 ratio. The Ferrari has an additional gear over both cars, and it has less total drag area than the GT-R. If you take an acceleration chart from a manual-transmission car, and remove the deceleration that can occur during a shift, in which the car may have to effectively re-cover 2-3 mph lost during each shift, then you'll see how DCT can affect the trap speed too.

R&T tested the 3595-lb LP560, which has a comparitively archaic transmission, to a 129.5 mph trap speed in fairly warm conditions (89 degrees F). Factor in the 458's DCT, slightly shorter gearing, 200-lb weight advantage, and perhaps cooler conditions and that 134 mph trap speed sounds entirely believable. Even removing the variable of driver skill (the Lambo had the "e-gear" paddleshifters), the LP560 is still losing about 1 mph, and time, on each of the 3 shifts to the 1/4 mile.

FIRSTC6Z06

I have a 2011 Turbo "S" (530HP) with the improved PDK 7spd and my second C6 ZR1 coming w/museum delivery in 2 weeks. (sold my '09) The PDK is the fastest shifting most amazing transmission I have ever experienced. The Porsche's AWD and lightning fast shifts are not matchable by any manual shift car. With that said, the manual shifting in a ZR1 is something that any real sports car guy shouldn't have to give up. It's a better drivers experience! It's ironic that the Turbo "S" is not available with a manual trans and the ZR1 is not available with an Auto trans.

Those who are looking for a best time will want the dual clutch auto trans. GM should make one for the ZR1 and their inventory problems would go away quickly. Even at an increased cost, many are waiting in the wings for it to happen.

vette6799

It seems like it is a lot easier make power than it is to transfer the power effectively to the road. As you noted, while you lose some of the fun factor when replacing your manual transmission with a dual clutch, there is simply no comparison of the advantages you gain with the dual clutch transmission. I don't know if the 458 comes in a manual transmission, I don't think it does, but I have read that the 430 had both the manual and F's F1 transmission and most drivers purchased the F1 version.

AWD addresses another issue but adds some weight and certainly adds to the ability to transfer power as shown, I think more and more irrefutably by the numbers. At some point, GM needs to consider these options. The dual clutch transmission, one would think, is the easier of the two items to implement.

Guibo

You're right, the 458 doesn't come with a manual. Road & Track explains why:
"the 458 isn’t available with a manual. Sacrilege? To some, yes. But to Ferrari, it’s only natural. Less than 1 percent of F430s were sold with a manual gearbox..."

It's a similar story over at Lamborghini. From an article on Automobile Magazine's website on the LP570:
"Although Lamborghini still offers the classic manual transmission complete with chrome gate, polished golf-ball shift ****, and wonderfully positive action, the take rate has dropped to less than two percent."

CrystalRedMetal ZR-1

I know the Porsche typically beats a ZR1 on the street from a stop... My focus was with the seriously high trap speed in particular. Let's get one thing straight - a 500 hp Porsche is NOT trapping 134 mph. If it were, it is certainly not doing it with 500 crank hp, and especially not with 3400 lbs. Now with the Ferrari, I also believe it not to be able to trap that high with only 560 hp. Could be wrong with this new tranny in effect, but I still have my doubts.

For the record, vehicle launch does not significantly change trap speeds. A ZR1 trapping 134 with a terrible launch will likely trap about the same with a perfect launch. Main difference will be it will cross the finish line sooner with a better launch. Not so much at a higher speed.

I only doubt a 134 mph trap with a 560 horsepower 3400 lb car. That's all that stands out to me. I dispute the power specs more so than the times.

Looks like a very advanced car either way... I kind of hope it really is doing this trap with only 560 hp. That can only mean MUCH faster acceleration in future cars. In a few years, you might be able to grab a used 458 Italia for about a hundred grand less than MSRP. Depending on mileage of course. Then I might buy one!
