Welp. official price and specs are out! Look at the fucking trap speed on that thing, that's a 10 second car bone stock in the right hands!

We knew the 2009 Chevrolet Corvette ZR1 was likely going to be priced right around 100 grand when it finally hit the showroom floor, and GM hit the target.

The ZR1''s base MSRP of $103,300 (including an $850 destination charge) moves the $105,000 number thanks to a $1700 gas guzzler tax, but we''re guessing no one lining up to buy the fastest and most technically advanced production Corvette of all time will mind in the least.




Chevrolet also released several performance numbers for the ZR1, and they''re jaw-dropping:

* 0-60 mph in 3.4 seconds
* 0-100 mph in 7.0 seconds
* Quarter-mile elapsed time of 11.3 seconds at 131 mph
* 205 mph top speed

The ZR1''s claimed 0-60 time is .3-ticks quicker than the Z06 and its 0-100 mph of seven seconds is almost a full second faster than the Z06''s 7.9 seconds. It goes without saying that the ZR1, which is reportedly capable of a 205 mph top speed, is the equal of some of the world''s greatest supercars, at a price point that''s much, much lower than the Ferraris and Lamborghinis of the world.

As for the ZR1''s equipment list, the car comes with similar packaging to that of the Z06, but an upgraded option package is available that will set you back an additional $10,000. Here''s the partial list of what you get for the extra scratch: power-adjustable, heated and leather-trimmed sport seats with an embroidered ZR1 logo; side air bags; Bose audio system and navigation system; Bluetooth connectivity; power telescoping steering column, and a custom leather-wrapped interior available in four colors. Chrome wheels ($2000) are the only other available option available for the ZR1. Add all the options in and you''re looking at $117,000, before dealer markup, of course.

Not that fuel economy really matters for a car in this stratosphere, but the EPA has also officially rated the car at 14 mpg city / 20 highway, which despite the gas guzzler tax, are pretty impressive numbers considering the ZR1''s supercharged, 6.2-liter LS9 engine that pumps out an SAE-certified 638 horsepower and 604 lb-ft of torque lurking under the car''s carbon fiber hood. It isn''t quite the most fuel efficient vehicle in its stratosphere, but it''s close.

Below is all you need to know about the LS9 engine:

* Aluminum cylinder block with iron cylinder liners that are finish-bored and honed with a deck plate installed
* Forged steel crankshaft with a nine-bolt flange
* Titanium connecting rods and forged aluminum pistons
* Stronger, cylinder heads with 2.16-inch (55 mm) titanium intake valves and 1.59-inch (40.4 mm) hollow-stem, sodium-filled exhaust valves
* Camshaft with 0.555-inch (14.1 mm) lift for excellent idle and low-speed driving qualities
* A dry-sump oiling system with 10.5-quart (9.9 liters) capacity
* Integrated oil cooler and piston-cooling oil squirters
* Intercooler cover visible through the hood window that features ZR1-unique blue accents and "LS9 SUPERCHARGED" embossed on the left and right sides


As soon as we get our hands on a production ZR1, you can be assured we will test it to its limits to see if we can match or beat GM''s numbers. One thing''s for certain, the ZR1 hasn''t even hit the streets yet and it''s already arguably one of the most amazing production cars the world has to offer.

So Chevy is making a new version of the base Z06 that will closely compete with the ZR1. Pretty sweet!

For the truly hard-core Corvette fanatic who likes to spend weekends thrashing his or her car at the track, there is only one Corvette worthy of consideration: the Z06. However, thanks to the ZR1, the lightweight, normally aspirated 7.0-liter coupe is no longer the absolute quickest Vette, but it is felt to have the most responsive handling. What it doesn't have is the uber-cool carbon-ceramic brakes, carbon-fiber body panels and magnetic ride active damping system of its supercharged sibling. That can now be changed to past tense with the birth of the Z06 Carbon edition announced today by General Motors.

The Z06 Carbon was created to celebrate the 50th anniversary of the first appearance of the Corvette at the 24 Hours of Le Mans when John Fitch and Briggs Cunningham won their class and finished eighth overall. The Carbon edition is essentially a Z06 with a ZR1 chassis and some of the carbon skin. When production starts this fall, only 500 examples will be made and they will only come in two colors, Inferno Orange and Supersonic Blue. All examples get black-painted wheels and a black interior upholstered in leather and suede.

One element unique to the Z06 Carbon is its hood. The profile of the new carbon fiber hood is identical to that on the ZR1 but without a transparent window. That makes it the lightest hood ever on a Corvette and, according to chief engineer Tadge Juechter, it truly is a featherweight. ZR1 owners looking to swap out their hoods will be disappointed to learn that the Carbon hood will not fit their cars. Because of the absent window, the Z06 hood has different structure underneath that won't clear the ZR1 engine's intercooler.

The splitter, rocker extensions and roof of the Carbon are painted black instead of the super-expensive clear-coat used on the ZR1. The headlamp pockets and wheels are also painted a glossy black giving the Carbon a decidedly sinister appearance, particularly with the steel blue paint combination.

According to Juechter, the upgraded suspension and brakes give the Z06 a real boost on the track too. Even with the same powertrain, the Corvette circulates both Laguna Seca and the Milford Road Course three seconds a lap faster than a 2010 Z06. The addition of the magnetic ride damping system should also make the Z06 Carbon more livable on the road as well.

For those who don't manage to get one of the 500 Carbon editions, most of the good bits will be available as part of two option packages available for 2011 models. The Z07 package provides all the mechanical goodness of the Brembo brake system, wheels and tires and the MR suspension. The carbon fiber package includes the splitter, sill extensions and rear lip spoiler. Unfortunately, the hood is only available on the 500 limited edition cars. The Carbon and new option packages go on sale in late summer at prices that will be announced closer to launch date, so stay tuned.

oh sweet mercy that is hot. :bow:

[Goodspeed]

I was about to post that in the H&B'ed thread. That just might be the sexiest thing America has ever made, ever.

I can only imagine how awesome that car is. I've driven a few C6 Z06s (both modded and stock) and ridden in a ZR1 and I could probably die a happy man because of that. I'd love to snag a ride in this when it comes out.
