The Chevy/Holden/Opel/Vauxhall AmperVolt? Meh. There couldn't be a better green car for the environmentally responsible crowd to be smug about than the electric ZR1. It's so electric, it'll send a jolt to the competition with uninterrupted green performance thanks to its optional 6-mile long extension cord. Pick one up today at your local Hangin' Byathread Motors. We'll be picking one up soon with the dual-speed, performance Makita Power Exhaust system. It's gonna be badass.

I spent most of my time in America this time in a new Corvette ZR1. It is a fabulous car. Mesmerisingly fast, good looking and amazing value. But after three days the damn thing was beginning to disintegrate. It made me growl with annoyance and despair.

The thing about the ZR1 is that it’s not just mesmerizingly fast, good-looking and an amazing value (at least here. In England it costs $200k), it’s built extremely well too. The aluminum chassis is as basic and as strong as it gets, every piece of running gear is of the highest specification available and the carbon fiber bodywork is some of the most well-laid, best-fitting we’ve ever seen.

Then there’s the interior, which we think is what Clarkson is talking about. It’s cheap...really cheap. Wonky plastic buttons abound, the 3ZR package brings ugly, atrociously stitched leather in poorly chosen color combinations and the steering wheel belongs in a Cobalt, not a 205 MPH supercar. But despite all that, it should fundamentally be capable of holding itself together. We just don’t know what Clarkson is on about. Do you? [via the Sunday Times]

FACTS

1. ZR1 production has been halted at Bowling Green despite orders to fill.
2. There is nothing wrong with the ZR1 itself. No production line issues that warrant it being stopped.
3. There is no official word from GM yet. Key word, 'official'. But, there is 'word' and we are hearing it.

INFO COMING IN

1. The ZR1 model itself may be on the chopping block, or has already been cancelled.
2. GM is losing their butts on each one.
3. This is a management decision and for financial reasons only.
4. Major changes coming for Corvette production.

Specific to the ZR1, the 285/30-19 front and 335/25-20 rear tires use a different compound from that of the normal PS2s (which can also be found on the 2009 Cadillac CTS-V), designed to deliver ultimate track performance while retaining the ability to last for 20,000 miles of road use. We’re guessing burnouts may reduce their life expectancy substantially.

Unlike earlier versions of run-flat technology, which we weren’t big fans of thanks to increased unsprung weight and a harsher ride, these latest Pilot Sports’ reinforced sidewalls actually contribute to handling while inflated, helping to transfer braking and cornering loads in a more direct fashion.

Additionally, the tires make use of a two-part tread design with large, stable blocks on the outside for maximum grip (the ZR1 can pull 1.05 Gs on the skidpad) and a more grooved tread in the middle for better water dispersion and lower tire noise. The sections are joined by a special “lightning bolt” decoupling channel, which allows each section to movie slightly, independently of the other.

We drove the ZR1 on both the road and track — in dry conditions only — and never found the tires to be lacking. On the track, they deliver considerably more grip than expected, while on the road they ride surprisingly compliantly, at least for such a big tire. Michelin hasn’t finalized prices for the PS2 ZP yet, but expect replacements to cost “$300 to $400 a corner.” [Michelin]

Halfway through a day's lapping, halfway around the Lutz Ring and full throttle at the top of third gear is bringing me and a red ZR1 into a 180-degree corner way too fast, while the blind crest just before it — taken at maximum power and maximum cornering — has us way off line too. In any other supercar, especially one as hairy as a Viper or as rear-engined as a 911, this would be a serious moment, probably resulting in one of my notorious off-track excursions. But today I can just haul on the brakes all the way through turn-in and up to the apex and then get back on the power — hard. The result: sweaty palms instead of trashed carbon fiber body work.

The first thing you need to do with the ZR1 is throw out any preconceived notions you have about it. Isn't it just a more extreme Z06 with 131 more horsepower or an answer to a question no one asked? No. It's a comprehensively re-engineered vehicle that shares little in feel with either the standard Corvette or the Z06, outperforming both on the track, obviously, but also, surprisingly, on the road. How? A remarkably civilized yet awesomely powerful engine; an easy-to-use gearbox; compliant-yet-capable suspension; and a chassis that simply overachieves at any task you give it.

While based on the standard car's LS3 V8, the ZR1's LS9 makes its power with the aid of a Roots-type supercharger whose intercooler cover is visible through the tacky Lexan hood window. With 638 HP and 604 lb-ft of torque, its speed should come as no surprise, but its character will. Equipped with a dual-mode exhaust, there's little hint of its performance at low speed, the RPMs dipping if you pull away on light throttle. Up to 2,500 RPM (about all you need on the road — it delivers 320 lb-ft at 1,000 RPM), it feels like something that belongs in a big German luxury car. It's torquey, quiet and, combined with the ZR1's 3,364 lb curb weight, it makes driving effortless.

It's when you begin to climb into higher RPMs at larger throttle openings that the LS9's performance reveals itself in its absurd volume. A second exhaust valve opens, taking the engine note from refined to apocalyptic. The all-consuming sound focuses your attention on nothing but the road in front of you. But it lacks any aural indication of its supercharger. For reasons that escape us, the Corvette engineers went through elaborate steps to eliminate the whine, even doubling the number of teeth on the lobe drive gears to move their sound beyond the human ear's range of perception. Tap into the loud zone and everything in front starts to come at you very fast. 300 HP arrives at just 3,000 RPM before peaking at 6,500, leaving 100 RPM before the redline. The close-ratio gearbox (unique to the ZR1) means shifts come fast, but the wide spread of power and torque means you can leave it in third for pretty much anything above 30 MPH.

Like the engine, that gearbox does little to hint at the ZR1's ultimate performance. A twin-disc clutch leads to easy pedal throw, while a precise gate makes finding gears simple. This isn't a fire-breathing monster, but instead a car anyone could drive competently — even for long distances (it's comfortable) or at high speeds (its limits are so high that you need to try very hard to find them).

In fact, the only thing detracting from the ZR1's grand touring credentials is the interior. The only options on the $103,300 car are an awful set of chrome wheels and the 3ZR upgraded interior package, which succeeds in moving the interior from cheap and nasty into luxurious bass boat territory with more embroidered ZR1 and Corvette logos than my fragile mind could comprehend. We have a hard time accepting the 'value' excuse; for this kind of money we'd no longer like to feel like a Jeff Foxworthy punchline. An automatic transmission is, thankfully, not an option.

The ZR1's road ability is boosted by the two-mode magnetic damping. Select "Touring" on the center-mounted ride-control knob, and, while it can't hide that the ZR1 wears 335/25-20s on the rear, it rides comfortably enough to make you forget you're driving something capable of lapping the Nurburgring in 7:26.4. The damping adjusts itself near-instantaneously to maintain grip on rough surfaces. You won't feel this happen, but you will notice how unflustered the ZR1 is no matter how crappy Michigan roads may be.

The real magic of the ZR1 isn't that it's capable of any of the above, though. It's that it will make you forget all of its intimidating performance figures and fancy technology the second you take a corner at speed. Despite all the headline numbers, this car isn't about power, it's about handling.

Built on the same aluminum-intensive chassis with fancy magnesium bits as the Z06, the ZR1 uses independent suspension all-round, but here it arrives with bespoke tuning capable of coping with the 1.05 lateral Gs the purpose-made Michelins make possible.

Conventional wisdom states that a front engine, rear-wheel drive car capable of these numbers should be incredibly difficult to drive, with a significant predisposition toward slamming into immovable objects, backward. In fact, before driving the car, Ray and I discussed whether or not the ZR1 was set to become the cheapest way to kill an inexperienced driver quickly, but that's simply not the case. It's so competent a car that it makes the 638 HP feel unremarkable. Two people went off-course the day I was at the track, but both did so because they got intimidated by the sheer speed at which they were traveling. Had they simply looked where they wanted to go, instead of off into the grass, the Corvette ZR1 would have made it around the corner — the same nasty off-camber, downhill one both times — much faster than they were actually traveling.

This is only my second track day since getting the cast off and I'm still not back to full health. And, I hate to admit it, but I'm a little more cautious than I used to be. The Lutz Ring is also an incredibly intimidating track. Jim Mero, the guy with the 'Ring record, described it as the best possible preparation for his attempt as it packs all the German track's challenges into a space not two miles long. That includes the lack of run-off — guardrails line the track's fastest corner and you need to get within a couple inches of them to be really fast. But two laps into my first session and I'm ringing the car out in second and third gear. No matter the speed or the amount of ill-advised braking, it turns in and holds a line without drama and accelerates out under full throttle without stepping wide. In fact, it rapidly becomes apparent that, without intentionally trying to do so, I'm incapable of making the ZR1 misbehave. Even topping out the suspension over the track's two jumps then slamming hard on the massive ceramic brakes just as the car regains traction fails to make it lose composure. Just like the two guys who went off, I'm unable to reprogram my brain enough to accept the ZR1's ludicrous speed. This is the first car I can say this about in a long, long time — the ZR1 is too fast for me.

That's not to say I can't enjoy it. This isn't a PlayStation game. The ZR1 is a rear-wheel drive car that needs significant driver input in order to make it around a track or down the road quickly. It's that involvement, not just ultimate speed, that is its reward. Even if it provides you with better tools to do so than anyone else, the Corvette ZR1 still challenges you to try and exploit its performance; it's the level of that challenge and the level of involvement required to meet it that makes the ZR1 truly special.

Instead, we're treated to GM test engineer Jim Mero — we think — driving one of the invited journalists around the road course at the General's Milford Proving Grounds. We know Mero's a pretty damn good driver — he shot the ZR1 'round the Nubrugring in record time. Maybe he was just having a bad day today, but how many cones did he hit on this particular run 'round the "Lutz Ring?" Probably a lot less than the number whoever he was driving would have had he gotten behind the wheel himself.

Not to say he didn't. Whoever it is in the passenger seat probably did get a few minutes of limited driver seat time. We just hope this video won't cast aspersions on "test drives" coming out of the event. [More over at VetteTube]

Jalopnik reader and tipster Kyle spent the July 4th vacation up near Michigan's pinkie finger in Traverse City. On a quick jaunt down to Elk Rapids, a town not too far away from there, he ran across a yellow 2009 Corvette ZR1 sitting pretty at the roadside in the resort town. Maybe it's just tired and taking a vacation over the summer GM shut-down. Although we did notice there's no manny plates on it, that may just be because it's a "captured test fleet" vehicle. In all fairness, we're still not quite sure we get the distinction between "captured test fleet" and you know, a "test vehicle." Maybe there's no distinction. Anyone want to take us up on our question — drop a note into the comments below.

"I put a deposit down for the 2009 ZR1 about 2 1/2 years ago at "my" chevy dealer from whom I have bought many GM cars, including trucks, vettes. I have probably bought 15+ GM vehicles over the years. I was told 2 1/2 years ago that the price for this "iffy" car would be around the same ratio as the 5K overcharge I paid for my 2006 Z06.

I was called to order my ZR1 yesterday since I was #1 on the allocation list of this dealer's 4 allocations. I was told that by the way the price would be between 2-4 times the MSRP. Tadge Juechter, the Chief of Corvette Engineering, has urged GM ZR1 dealers to respect the MSRP. I am very upset with the greed and disregard for customer loyalty in a down economy. Is there any recourse?"

That $103,300 (plus a $1,700 gas guzzler tax) which gets you a bare bones, lightweight interior based on that of the Z06. For an extra $10k Chevy will sell you the 3ZR package, which brings interior upgrades like power adjustable seats, sat/nav, more airbags, ZR1 embroidery etc.

DETROIT - The official Corvette ZR1 numbers are in and they're good. Very good:

* $103,300 MSRP (including $850 destination charge)
* EPA-estimated fuel economy of 14 city and 20 highway
* 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

The Corvette ZR1 also has a top speed of 205 mph (330 km/h), making it the fastest Corvette ever produced and ranking it among the global super cars of commensurate performance. None of those other super cars, however, equals the ZR1's performance-per-dollar ratio.

"The ZR1 is an incredible machine by any measure," said Ed Peper, North American Vice President, Chevrolet. "There's simply no other vehicle in the world that does a better job of balancing performance, price and fuel economy."

Performance perspective
The Corvette ZR1's 0-60 performance is 0.3-second quicker than the already-quick Corvette Z06 and the 0-100-mph performance is nearly a full second quicker - 7 seconds vs. the Z06's 7.9 seconds. It is performance that is equal to or better than many super cars costing substantially more.

"A favorable power-to-weight ratio gives the ZR1 an advantage over the competition and performance that has to be experienced to fully appreciate," said Tom Wallace, Corvette chief engineer. "Of course, on a racetrack, drivers of competitors' cars may appreciate the ZR1 in a whole different manner."

And the racetrack isn't the only place where the ZR1 trumps its super-car competitors - it beats them at the gas pump, too. According to fueleconomy.gov, the ZR1's EPA-rated 14 city and 20 highway mileage ratings beat 2008 competitors such as the Ferrari 599 GTB Fiorano (11 city / 15 highway); the Lamborghini Murcielago (8 city / 13 highway) and the Aston Martin V8 Vantage (12 city / 19 highway). They're competitive with the Dodge Viper (13 city / 22 highway) and the Porsche 911 GT3 (15 city / 22 highway).

Under the carbon-fiber hood
A new LS9 6.2L supercharged small-block engine powers the ZR1's performance capability. Heavy-duty and lightweight reciprocating components support high-rpm performance, while a new, sixth-generation supercharger (and complementing charge-cooling system) helps the LS9 make big power and torque across the rpm range. The engine is hand-assembled at GM's Performance Build Center, in Wixom, Mich.

In addition to the LS9 engine, the ZR1 is a technology powerhouse, designed with lightweight and unique components that reinforce its performance with a confidant feel on either a highway or road course.

Options
The standard ZR1 comes with accoutrements based on the Z06, including lightweight seats and lightweight content. The available uplevel interior package includes power-adjustable, heated and leather-trimmed sport seats (embroidered with the ZR1 logo); side air bags; Bose premium audio system; navigation system; Bluetooth connectivity; power telescoping steering column; custom leather-wrapped interior available in four colors and more. Chrome wheels are the only other available option on the ZR1. Detailed pricing noted below.

* $103,300 Base MSRP including destination
* $1,700 Gas guzzler tax
* $10,000 Option package
* $2,000 Chrome wheels

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
