Update: 2009 Chevrolet Corvette ZR-1 Top Speed Video 205MPH

What is there to say expect Wow. Earlier we brought you the official power specs on the 2009 Chevrolet Corvette ZR1 (638-hp and 604 lb-ft). However, we had no official 0-60 or top speed numbers given to us in the press release.
Well thanks to GMNext, we now have a video of the Corvette Development Engineering team taking the new ZR1 to the test track in Papenburg, Germany and putting the pedal to the metal to see just how fast it could go. The Vette ZR1 hit a top speed of 205mph (330km/h) with the Corvette Development Engineering team behind the wheel.

OFFICIAL: 2009 Chevrolet Corvette ZR1 Revealed – LS9 V8 Hits 638 HP!

The folks over at General Motors have finally released offical specs on the brand new super-Vette Corvette ZR1 with its earth moving supercharged LS9 engine. Its 6.2L supercharged V8 will pump out a jaw dropping 638 HP, nearly 103 horses per liter — and a tire shredding 604 lb-ft of torque. Undoubtedly this will let the new supercharged Corvette ZR1 break that all-important 200 MPH speed barrier.

Below is the full and official press release. Pictures to Follow soon!

CHEVROLET ANNOUCES CERTIFIED POWER RATINGS FOR THE NEW CHEVROLET CORVETTE ZR1: 638 HP FROM THE SUPERCHARGED LS9 V-8

PONTIAC, Mich. – When it was introduced at the North American International Auto Show in Detroit earlier this year, the 2009 Chevrolet Corvette ZR1’s power was estimated at 100 horsepower for each of its 6.2 liters of displacement. GM Powertrain has completed SAE certification of the ZR1’s supercharged LS9 V-8 and the results exceed the estimate: 638 horsepower (476 kW) and 604 lb.-ft. of torque (819 Nm).

The LS9’s output is nearly 103 horses per liter, or just about 1.7 horses for each of the engine’s 376 cubic inches. It is unquestionably the most powerful automotive production engine ever manufactured by General Motors and enables the Corvette ZR1 to achieve a top speed of more than 200 mph (322 km/h).

“One of the most amazing things about the Corvette ZR1 is the level of refinement that our designers and engineers have attained. Even with all that power, this car has road manners that will allow our customers to enjoy it on the streets as a daily driver, and on the track,” said Chevrolet General Manager Ed Peper.

The Corvette ZR1 goes on sale this summer. Its 638-hp supercharged engine is complemented in the chassis by heavy-duty components not offered in any other model, including a six-speed manual transmission with race-hardened gears and dual-disc clutch technology that delivers exceptional clamping power and lower inertia, as well as strengthened axle components.

Fuel economy testing has not been completed, but engineers are confident the ZR1 will be the most fuel-efficient 600-plus-horsepower car on the market.

The LS9 engine is hand-built by specially trained technicians at GM’s Performance Build Center in Wixom, Mich. It is a unique, small-volume engine production facility that also builds the Chevrolet Corvette Z06’s LS7 engine and other high-performance GM production engines.

“Developing the LS9 involved more than simply striving for a great horsepower number. Endurance and reliability testing have shown the engine to be robust and low-maintenance, just like other engines in the small-block family,” said Sam Winegarden, executive director, engine engineering for GM Powertrain. “That it is distinguished as the most powerful engine ever from General Motors is a source of immense pride among everyone involved with the LS9.”

Supercharged aspiration
The key enabler of the LS9’s performance is the industry’s first production application of a new, positive-displacement Roots-type supercharger that has a unique four-lobe rotor design. Its design promotes quieter and more efficient performance, while the large, 2.3-liter displacement ensures adequate air volume at high rpm. Maximum boost pressure is 10.5 psi (0.72 bar). It is teamed with an integrated charge cooling system that reduces inlet air temperature for maximum performance.

“The combination of large displacement and the new, four-rotor design broadens the effective range of the supercharger, allowing the engine to make more power at lower rpm and sustain it throughout the power band,” said Winegarden. “The low-end torque is tremendous and the high-rpm charge from the supercharger is simply amazing.”

A raised hood provides adequate clearance for the LS9, while a polycarbonate window in the hood provides a view of the engine beneath it.

LS9 details
The LS9 features many unique design and manufacturing details that support its high-performance nature. They include:
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, rotocast 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

Introducing The Fireblade Concept, A Corvette ZR1 In Meaner Clothing

Fireblade Concept – The New 2009 Corvette ZR1

It’s hard not to like the New Chevrolet Corvette ZR1. Any time you take a standard Corvette, give it more power, lighter weight, bigger brakes and a better suspension, our supercar-loving hearts start thumping right out of our chest.

It’s the Bat-Corvette, its the Corvette Reventon! NO! Its called The Fireblade Design Concept, which is basically a re-skinning of the already potentially iconic Corvette ZR1 by South African designer Idries Noah.

Now, currently, this is nothing more than a 3-D dream car, but it’s still making at least one of us feel that pants-tightening excitement we haven’t felt since the first time we spotted the ZR1 in an embargoed press event around the time of the last Detroit Auto Show.

Follow the link for some high quality pictures of the Fireblade Design Concept at seriouswheels.

The idea for the FireBlade was to “reflect raw power” and to “be a brute, a car that has muscle car qualities”, according to designer Noah. Inspired on such mythical vehicles like the Shelby Daytona and Corvette Stingray, the FireBlade would have a promising career if it ever had the chance to see the production lines.

Spied: 2009 Corvette ZR1 Sets Nürburgring On Fire

The 2009 Chevrolet Corvette ZR1 is almost set to be unleashed in the world. But while we wait, it’s just been caught doing hot laps on the Nürburgring. As the most powerful Corvette ever built, we expect it to run impressive lap times – And the ZR1 does not disappoint! It was captured on video running consecutive laps in the 7:40 range! This unofficial time puts it well into the race for the fastest production car ever around the Nordschleife.

Not only that, but the conditions of the “test” weren’t ideal, with a cold and wet track and lowly engineers at the helm. ZR1 Chief Engineer Tadge Juechter was quoted saying the ZR1 will beat any production car’s track record anywhere in the world, and this news goes pretty far to back that up. Head on over to Edmunds Inside Line to see the video and hear the beast in its element for the first time.

Introduced earlier this year at the 2008 Detroit Auto Show, the 2009 Chevrolet Corvette ZR1 will be a limited-production version of the standard Corvette. It features a supercharged 6.2-liter LS9 V8 rated at a jaw dropping 620 hp and 595 pound-feet of torque. A 6 speed transmission sends power to the enormously large 335/35R20 tires. Extensive use of carbon fiber gives the ZR1 its unique look and helps it weigh only a few hundred pounds more than a standard Corvette Z06.

Looks like this Chevy they might have some serious competition with the Nissan GT-R already runing laps of 7:38 at the Nurburgring. But we’re guessing the ZR1 can shave off a few more seconds without much trouble. The only question now will be how much quicker than 7:38 can it go? We’ll keep you posted.
