Corvette Chief Engineer (and Autoblog commenter) Tadge Juechter said last week that the new ZR1 "will be able to take the production-car track record at any racetrack" and should lap the famed Nurburgring race track in Germany in "seven minutes, twenty-something seconds." Considering Nissan just posted a new official lap time of 7:29 for the GT-R and that the GT-R V-Spec is reportedly clicking off laps in 7:25, them sounds like fightin' words. Well, the ZR1 is officially being flogged around the Ring as we speak, though no one has yet to report a lap time for this gorgeous red prototype that was spotted by KGP photographers. BridgetoGantry.com reports that yesterday there was a helicopter over the track "chasing something that sounded very V8 and awfully supercharged," so perhaps lap times will soon be forthcoming. We imagine the supercharged LS9 V8's 628 horsepower and the ZR1's 205-mph top speed will not disappoint.

Corvette ZR1 chief engineer Tadge Juechter recently sat down to participate in a live chat on GMNext to answer questions about Chevy's new supercar, with topics ranging from fuel-economy to production numbers.

GM hasn't run its fuel economy test yet, but in a previous release from the General, it expects the ZR1 to be the most fuel-efficient 600-hp vehicle on the market. Juechter did say that the ZR1, "will be somewhat less [fuel-efficient] than a Z06," which is currently rated at 15/24 by the EPA, "and we expect a small gas-guzzler tax [on the ZR1]." Production will be limited to 2,000 units each year for worldwide consumption and pricing will be revealed sometime this month.

Juechter went on to say that ZR1 accessories wouldn't be made available for lesser Corvette models, so buyers won't be able to option up for carbon-ceramic brakes or Michelin tires on their Z06s. When asked if engineers considered all-wheel-drive for the ZR1, he emphasized that making the vehicle as lightweight as possible was a top priority and that an AWD system "would have added too much mass." And on the topic of price gouging by dealers, Juechter said only one thing: "We're strongly encouraging dealers to charge MSRP." Good luck on that.

The Nissan GT-R's 7:29 lap record won't stand for long if Chevrolet has anything to say about it. Speaking with InsideLine, Corvette Chief Engineer, Tadge Jeuchter, says that the ZR1, "will be able to take the production-car track record at any racetrack," and that although Chevy doesn't have a production version of the uber-Vette at the Nurburgring yet, they're expecting a lap time of "seven minutes, twenty-something seconds." That sounds like smack-talk to us. But while the ZR1 might have the potential to best the GT-R's 'Ring time, the 550-600 hp elephant in the room is the forthcoming GT-R V-Spec, which is already putting down (roughly-timed) laps around the North Loop in the 7:25 realm. Let the battle begin. We're making popcorn now.

General Motors, Chevrolet and the Corvette team are clearly proud of the power ratings they just announced for the Corvette ZR1. With its LS9 V8 producing 638 horsepower and 604 pound-feet of torque, you would expect the most powerful Corvette ever to be the fastest as well. And you'd be right. On its GMNext website, GM has revealed that its taken the ZR1 all the way up to 205 mph at its test track in Papenburg, Germany. And they had a video camera on board to capture the moment. The sense of speed is incredible, and even we got excited when the ZR1 climbed the banked oval and made other vehicles track testing that day look like stationary objects. Keep your eye on the digital speedometer in the bottom center of the video and watch as the ZR1 is still pulling strongly above 180 mph.

We remember a time when the Ferrari F40 and Lamborghini Diablo were battling for the title of World's Fastest Production Car, and the Diablo narrowly beat out the F40 by claiming a top speed of 204 mph. Now we have a Chevy that can go 205 mph. What a wonderful world.

When Chevrolet officially announced the new Corvette ZR1 just before the Detroit Auto Show this year, it hadn't yet finished the certification of its new power-plant, the supercharged LS9. At that time, all the engineers would tell us was that the supercharged 6.2L V8 would produce a minimum of 100hp/L or 620 hp. Three months have passed since we got our first official look at the LS9 and the numbers are now in. According to GM, the LS9 has now been SAE Certified at 638 hp and 604 lb-ft of twist. The official EPA fuel economy testing hasn't been finished and for people who buy a ZR1 it probably won't matter anyway. Nonetheless, GM expects the LS9 to be the most fuel efficient 600+hp engine in the world, a dubious distinction if ever there was one. A special team of technicians will be hand-building and testing the LS9 at GM's Performance Build Center in Wixom, Mich. Check out the articles below for all the details on the ZR1 and LS9.

From the Mustang to the Viper and Veyron, Hennessey Performance has spread its abilities across the performance car spectrum. And with hi-po vehicles like the IS F, ZR1, and GT-R on their way to buyers' garages, John Hennessey says he is working on packages to make all of those cars even higher-po.

The IS F looks to be the first in line, with the experiment subject arriving at Hennessey's shop next week. The car will be a test bed for "headers, exhaust and air induction systems first. Then maybe a blower." He's also got his eye on the baddest boy Corvette ZR1, for which his website advertises "700+ HP coming soon!" The physics-defying GT-R is in the crosshairs as well, and if he can make it better than it already is, that would be among the best testaments for his services.

Coming down just a notch -- but still up there -- the Cadillac CTS-V and Camaro will get their chances for glory as well. While all of this sounds great, what we really hope is that none of this extra work causes Hennessey not to give us the Venom. That's the package we are truly dying to see.

Leading up to the official reveal of the Corvette ZR-1, a rare week went by when we didn't see spy shots of the General's new super coupe eating up the Nurburgring. But still images don't tell the whole tale, so InsideLine sent its spies to the North Loop with a video camera to capture an uncloaked ZR-1 making the rounds on the 'Ring. According to the men behind the lens, they were able to clock the 620 hp, supercharged 'Vette running laps "in the low 7:40s," easily within reach of supercars costing substantially more than the ZR-1's estimated $100k price tag. But what about the elephant on the 'Ring in the room? The Nissan GT-R V-Spec.

As reported earlier this week, spies caught the GT-R V-Spec lapping the Nordschleife, and with stopwatches at the ready, they were able to time Godzilla's lightweight (by an estimated 330 pounds), more powerful (70 hp or so) sibling at an unbelievable 7:25 per lap. According to the crew that crudely timed the ZR-1, the track was damp, so that 7:40 time could easily be improved by at least four or five seconds. But that's still a long way off.

Obviously, both lap times should be taken with a grain of salt considering the less-than-accurate way in which they were captured, but that won't stop the smack-talk. Keep it civil folks.

We weren't really under the impression that the Corvette ZR1 was lacking anything. It's got the whole package - the power, looks, and even a (relatively) decent price tag. Apparently South African designer Idries Noah saw something much more and came up with his incredible design using the ZR1 as a platform. If you recognize the name, it's because Idries also came up with the unofficial Ferrari F250 Concept that we drooled over back in December. His latest design, dubbed the Fireblade, takes inspiration from the Stingray Corvette, Gillet Vertigo, and Shelby Daytona. Like the ZR1, it features the supercharged LS9 V8 displayed for the world to see under the clear portion of the hood. The result is a very attractive combination, and it's a shame that the car exists only in the digital world. Perhaps, like the Vandenbrink 599 GTO, enough people with excessive amounts of discretionary income will be interested in the design enough to consider a production version.

Yesterday we showed you an overview of the Corvette ZR1's heart, the force-fed 6.2L LS9 small block V8. In naturally aspirated form, the LS3 powerplant hits in the base 2008 Corvette hits 436 horsepower, but the addition of a new four lobe Eaton supercharger lifts the ZR1 into the horsepower stratosphere. Ron Meegan, assistant chief of GM's small block engine program, took us through the ins and outs of the ZR1's efficient new supercharger and we had our cameras rolling. Hit the jump to learn how the Eaton supercharger works and what makes it special. We also attached a one-minute video that details some of the differences between the supercharged LS9 V8 in the ZR1 and Cadillac CTS-V.

Bob Lutz has just posted a photochop on his GM Fastlane Blog of what the Corvette ZR1 could look like donning Michigan State Police livery. Bound to be the bane of speeders in the Wolverine state, the Corvette is sporting all the cop car traits necessary to scare the living Hell out of law breakers, including the prerequisite light bar, bumper guard (!) and spotlights. We, however, are particularly partial to the blacked out 20-spoke rollers. Despite lacking nanotechnology and more spoiler blades than a Cuisinart, we think this imaginary ZR1 cop car could give the new sci fi-inspired GT500KR-based KITT car a run for its money.

UPDATE: GM let us know this is not a prototype or anything official that implies a ZR1 cop car would actually be built. Someone sent this photoshopped pic of the ZR1 cop car to Lutz and he liked it enough to throw it up on his blog, much to the surprise of the PR department who didn't know anything about when we called.
