War of the Worlds- the 4 baddest rigs on the Planet go at it!


Supercars are like castles: the best ones come from Europe. Right?

For sure, it's long seemed that way. The Euro stars have always played in a price and performance stratosphere that makers from other continents simply couldn't (or wouldn't) attempt to match. Sticker price, schmicker price: In the spirit of the old adage "speed costs money, how fast do you want to go?" the premier machines from rarified houses like Ferrari, Bugatti, Porsche, Lamborghini, and Aston Martin cost hella big. But they also run unlike anything else on the road.

Uh, just a minute. Scratch that. For 2008, Nissan launched its ceiling-busting GT-R, a twin-turbo manga-robot on wheels with a price under $80K but an exhaust boom that rocked ears from the Nordschleife to Maranello. And now Uncle Sam is also strutting in the white-hot spotlight all oiled up and pumped: For 2009 comes the all-new Chevrolet Corvette ZR1, the most potent GM production automobile of all time, the best Vette ever, a star-spangled, supercharged sledgehammer in aluminum and carbon fiber with brakes lifted from the fastest road Ferraris ever built. Yes, it wears a base sticker that's difficult to utter in the same breath as "Chevrolet" -- more than $106,000 -- but the ZR1 also brandishes performance hardware straight from the parts shelves marked "No Compromises."

Clearly, the two new upstarts are begging to crack open a can of whup-ass in the hallowed halls of European-bred speed. Naturally, we're only too happy to help. We rounded up a GT-R and a ZR1 and headed off to the test track and five-mile high-speed oval of Chrysler's Arizona Proving Grounds with two of Europe's bona-fide superstars: the Ferrari 599 GTB Fiorano ("the finest all-around Ferrari ever," we said in July 2006) and the Porsche GT2 (which, in our May 2008 issue, we dubbed "one of the greatest sports cars the world has ever seen"). Along with us was former IndyCar driver and 24 Hours of Daytona winner Didier Theys (pictured below); he'd be our man at the wheel for a series of breathless, flat-to-the-floor top-speed runs, plus timed laps on the infield road course at Las Vegas Motor Speedway.

For three unforgettable days in the Arizona and Nevada deserts it was War of the Worlds. And NORAD didn't even notice.

Let's Do Launch

When you're dealing with an arsenal whose "weakest" member makes 480 horsepower, you know you're in for sound and fury worthy of a Force Five tornado. And, at the dragstrip, our four entries didn't disappoint. The only four-wheel-drive member of the group, the heady GT-R not surprisingly more than made up for its power disadvantage, blitzing from 0 to 60 mph (using its catapult-like launch-control system) in just 3.2 seconds -- tying the mighty, 612-horsepower V-12 Ferrari and leaving our test team shaking their heads in disbelief.

The ZR1 requires a skilled driver for maximum blastoff; too much throttle and you'll simply sit still while 604 pound-feet of torque transforms the rear tires into cumulous clouds. Do it right, though, and the Vette is gone in just 3.3 seconds (and you're still in first gear). Despite the traction advantage of its rear-engine layout and sticky Michelin Pilot Sport Cup tires (and its group-low 3270 pounds), the 530-horsepower Porsche GT2 trailed the group, reaching 60 mph in a ponderous 3.4 seconds (hey, with such a splendiforous surfeit of speed at our beck and call, we're already getting as picky as the judges at Miss America).

Past 60 mph, though, traction fades in importance and the physics of horsepower and aerodynamic drag rapidly change the game. By the century mark, you could pick the finishing order based on engine output alone: The 480-horse GT-R is trailing in last place, needing 8.0 seconds to reach 100 mph, versus just 7.3 for the GT2, 7.1 for the 599, and a mere 6.9 seconds for the power-ruling ZR1.

By the quarter-mile the big guns are leaving the GT-R further in their wake. While the Nissan is formidable indeed (11.6 sec at 120.0 mph), the others are unearthly. The GT2 trips the lights in just 11.4 sec at 127.9 mph, the 599 in 11.3 sec at 126.4 mph, and the mighty ZR1 in a blazing 11.2 sec at 130.5 mph. Translated from numbers into English: The ZR1 simply spanks the pricey European bluebloods.

ADVANTAGE: ZR1


Vmax . . . and Near Disaster

Winds gusting past 25 miles per hour threatened our top-speed runs (You ever been shoved by a stiff breeze while driving on the highway? You should try it at 200 mph). But the Indy-experienced, ever-cool Didier Theys was unfazed. "Hey, no problem," he offered with a smile. "Let's go."

Theys first strapped into the ZR1, and within four laps on the banked APG oval (check out our ZR1 videos to hear the cactus-rattling blare of that blown V-8 at full cry), he'd pushed the maximum Chevy to a wind-adjusted top speed of 200.4 mph. "I was flat going into Turn One," said Theys with Belgian-accented nonchalance. "Very nice. No problem." Then he added: "On the first lap I saw a coyote in the banking, but he see me and very quickly he run away!"

What was immediately obvious after the Vette's awesome blitz, though, was that even the five-mile APG circuit might not be grand enough to let the cars breathe fully. Our computer traces indicated that the ZR1 was still pulling (albeit with a tailwind) when Theys had to lift slightly for a bump entering Turn Three. And as the car blasted off Turn Four, the strong headwind pushed against the speedo needle all the way down the front straight. Given no wind and several miles of smooth, straight asphalt, the ZR1 might well have reached 203 mph. Maybe even 205. Still, we saw a verified 200-plus. The ZR1 is clearly a member of that most exclusive of performance clubs.

Next up: Ferrari 599 GTB. Coming off of the APG oval's Turn Four onto the main straight, Theys was visibly carrying more speed than in the ZR1 -- though the Ferrari was all but silent until it had rocketed past, the sonic splendor of its blazing V-12 only then scorching our ears. "The Ferrari is so planted, I was driving around the banking with just my left hand," Theys said later (he credits the downforce of the 599's elegant rear diffuser for aiding in stability). Yet barely into his third lap, Theys' voice came over our radio network. "Pirelli is gone," he said calmly. "I am coming in."

A minute later the 599 rolled into the pits, an ugly smear of rubber marring its left flank. The left-front tire -- bearing the brunt of the load on the clockwise track -- had delaminated in the banking at more than 190 miles per hour. The outside edge of the tread looked like it had been gnawed on by a Great White. Fortunately, Theys' skill had helped prevent disaster. Also fortunately, before the incident he'd already recorded a wind-adjusted top speed: 201.5 mph. Our test team began cleaning up the Ferrari as intern Carlos Lago immediately set off for Phoenix -- three hours away -- to pick up a replacement Pirelli.

For Theys, though, it was just another day in the office. As if nothing had happened, he strapped into the Porsche GT2 and again roared off on a perilous quest for maximum velocity. Four laps later, we had our number: 199.8 mph. The Michelins had remained intact, but as he pulled into the pits Theys wasn't happy. "The Porsche moves around a lot at speed," he said. "Kind of does a pogo front to back to front. The big rear wing is not as good as the Ferrari's underbody diffuser -- which, of course, Porsche can't use because there's an engine back there. Even though I lifted a bit before the Turn Three bump, when the GT2 went through there it really got unsettled. I didn't like it. Scary."

Finally, "Godzilla's" turn. The GT-R blasted out of the pits and vanished into the wind. Soon it reappeared in Turn Four, Theys gunning for glory, the twin-turbo, 3.8-liter V-6 screaming near its redline. Theys completed the lap, disappeared into the Turn One banking a third time, and a moment later came yet another ominous crackle over the radios. "I have lost a tire," said Theys, stoic as ever. "And some bodywork."

When the GT-R limped into the pits, the damage was shocking. The left-rear Bridgestone had delaminated catastrophically at more than 180 mph, completely shedding its tread and blowing out the rear bodywork as if it'd been hit by a mortar shell. Eerily, Theys had almost predicted just such a failure. "The rear end is walking around quite a bit on the banking," he'd said earlier after a practice lap. "The left-rear tire is working hard."

Yet again, Theys emerged unscathed and unshaken. And yet again he delivered the goods: a wind-adjusted top speed of 195.0 mph. We rolled the GT-R into the APG garage, where Chrysler's ever-helpful mechanics conducted a terrific improvised body-repair job. We also got on the cell phone to intern Lagos: "Say, after you pick up the Pirelli, we need you to swing by the Bridgestone store . . . "

During his post-runs debrief, Theys expressed plenty of praise for the ZR1 ("Very nice. Moved around a bit, though much better than the Porsche and the Nissan"). But he was clearly most enamored of the Ferrari. "By far the most poised on the oval," he said. "Effortless to drive fast." And, it should be noted, the fastest of the four to drive.

ADVANTAGE: 599 GTB


Laps of the Gods

Still reeling from the merriment of watching 50 percent of our field suffer near-catastrophe at speeds high enough to rotate a 747, our band packed up and hit the road for Vegas. No nickel slots or Cirque du Soleil for us, though: instead, we set up our own acrobatic show at Las Vegas Motor Speedway's road course.

Theys first hit the circuit in the ZR1. And right away he was on the limit, the big V-8 bellowing down the straights, standard carbon-ceramic brakes (borrowed from the Ferrari FXX and Enzo) clawing deep into the turns. "Balance is quite good," said Theys after his run. "I think the brakes need more cooling, and there's so much power you have to be very easy with the throttle. Also, I'd bet this car would easily be two seconds a lap quicker if it had paddle shifters. As it is, you have to fight to keep your hands on the wheel." We couldn't help noticing, though, that Theys was sure smiling a lot.

ZR1 lap time: 56.9 seconds.


The Porsche GT2 both looked and sounded fast, in every turn the traction-control computer firing to keep the rear tires in check, the turbo flat-six spitting and hissing until the straightway allowed full power. (We ran each car with its traction/stability settings turned on in their sportiest modes, the way most drivers would use them in the real world.) "Very nice steering feel," said Theys in debrief. "A bit pointy into turns. Can be tricky at high revs when the boost comes on hard. Lots of oversteer. But the grip level is high and the Porsche is quite predictable."

GT2 lap time: 57.5 seconds.


On the circuit, the Ferrari looked bigger than the other cars, perhaps because it tended to roll more through turns. Theys later verified that observation: "The balance is excellent, but you really need to anticipate the apex. Managing the weight [second-heaviest at 3750 pounds] is a big issue. But the traction control is really refined; it steps in just enough to be helpful, but doesn't cut your speed. And the engine is just wonderful. The powerband is so wide, I was running in third gear the entire way around."

599 GTB lap time: 58.0 seconds.


All eyes were on the stopwatch when the GT-R left the pits. Would the Nissan's techno-marvel four-wheel-drive system and punchy turbo mill push it past its considerably more powerful rivals on the tight, twisty LVMS infield? Would Godzilla vanquish the titans? Post-laps, Theys had this to say: "With the other cars you can control understeer with the throttle. But in the GT-R, more throttle means more understeer. When you reach the limit, though, it suddenly goes into snap oversteer. Engine response is very nice. Linear torque. Steering and braking feel are quite good. But mostly it understeers like a pig."

GT-R lap time: 58.1 seconds.


The GT-R finished a mere tick behind the Ferrari, but well off the pace of the Porsche and the ZR1. And while Theys had mostly good things to say about the handling of the top three, in general he was critical of the Nissan. "Lack of power is a reasonable excuse," he said, "but lack of handling is not."

ADVANTAGE: ZR1


Inside Info

The cockpit of the Ferrari is as stylish as a Milan fashion runway. Only the Italians could produce a driving cocoon so chic and sensual: brightly colored, expertly executed stitching; the aroma and rich patina of exquisite leather; more than $12,000 worth of optional carbon-fiber trim. You expect something very, very distinctive for more than $300 large, and you get it. Add supermodel and stir.

The ZR1 cabin, in contrast, reeks of plastic and adhesives. The odor hits you hard the moment you enter but soon dissipates as either your nose simply adjusts or your brain becomes intoxicated by the fumes. Nothing about the space says "special" -- even though our test car had the optional, $10,000 3ZR package, which adds a custom leather-wrapped instrument panel, ZR1 embroidery, and perforated-leather buckets, among other niceties. Sure, you enjoy fine Bose audio, dual-zone climate control, and a useful head-up display, but you could be riding in any Corvette. All the money is in the go-fast stuff -- and perhaps rightly so -- but given the ZR1's "swing for the fences" mission profile you'd think customers would be wiling to spend, say, another $5K or so for VIP digs.

The GT-R and GT2 are the boy racers in the group. The Porsche is all-business: superb, Alcantara-trimmed sport-bucket seats; high-visibility yellow-colored instruments; Alcantara steering wheel and shift lever; optional Chrono Package Plus timing computer. Everything fits tight and operates with precision. You're riding inside a Rolex.

The GT-R is a rolling PlayStation (and that's not a stretch: Sony helped develop some of the car's advanced electronics). Dials and switches abound. Buttons glow. Twirl a knob, and on the big central display screen you can monitor everything from acceleration g-force to brake-pedal input, front/rear torque distribution, turbo boost, lap times, and the airspeed velocity of an unladen European swallow. Be sure to keep an eye on the road now and then.

The Chevy is comfy enough, and the Porsche and the Nissan look and feel every bit the performance studs they are, but none of them can touch the Ferrari for supercar drama and sheer specialness.

ADVANTANGE: 599 GTB


The Dust Clears

So? Who wins the War of the Worlds? For sure, each car in this field qualifies as a superstar. The Nissan GT-R delivers 21st Century electro-wonder and shattering performance at a base price ($77,840) that borders on the unbelievable. The Ferrari 599 GTB Fiorano offers succulent styling, shameless hedonism, peerless refinement, and speed and handling matched only by a handful of cars on the planet. The Porsche GT2, which Theys dubbed "the raciest in the bunch," churns out effortless speed (the variable-vane twin-turbo engine feels naturally aspirated, so smooth is its power delivery) and seems utterly bulletproof. You know you could hammer on it all day long and it would never complain. The ZR1 has a few glaring flaws -- including a fade-into-the-traffic-flow exterior and a cockpit lacking almost any signs of flying first-class -- yet by nearly every objective measure (and most subjective ones, too) this new Chevy expands the performance envelope for premium supercars. And at a fraction of the price of the European thoroughbreds. In the supercar realm, the 2009 Chevrolet Corvette ZR1 rules.

America still sucks at the castle thing, though.

First Place: Chevrolet Corvette ZR1


Class-shattering power, race-car handling grip, monster brakes, and sweet control inputs leave even the bluebloods in this Chevy's wake.

Second Place: Ferrari 599 GTB Fiorano


Costs huge, but delivers huge, too. Still one of the planet's finest sports cars. And when it comes to sex appeal, forget it: The Ferrari is the only one you'd choose for a date with Gisele Bundchen.

Third Place: Porsche GT2


The Rolex of sports cars: brilliantly engineered and bulletproof. Unreal speed, hellacious grip, and superb controls -- everyday drives become laps at Le Mans.

Fourth Place: Nissan GT-R

That a machine this incredible finishes fourth shows you how spectacular the other three really are. At the price, nothing comes close. And if you think Nissan is resting on its 480-horsepower laurels, stay tuned for Act II: GT-R V-Spec.

Rolls Royce Considers and Electric Car

Rolls-Royce Considers Making an Electric Car

How can Rolls-Royce best avoid the gas-guzzler tax associated with its Phantom range? The answer may be easier than it seems: craft one that doesn't run on gasoline at all.

In fact, the firm isn't looking at alternative fuels but, in fact, an electric car. Britain's Car Magazine, having sat down with the top brass at the luxury car maker, says such an idea is actually under consideration.

As countries continue to impose increasingly stringent CO2 laws, an electric Phantom may be necessary. Tom Purves, Rolls-Royce's CEO, told Car that a day may come where "[Rolls-Royce] may need an electric car merely to sell in certain parts of the world."

But would the shocking idea of an eco-Roller go down well with customers? Purves thinks so, telling Car that many customers "drive small mileages exclusively in the city." If that weren't enough, the silent operation and strong torque long touted by the company would only be more evident in an electric version.

Purves says there are no firm plans as of yet, but imagines such a vehicle could be a collaboration between Rolls-Royce and its German parent, BMW - a relationship not unlike that which bore the 2009 Mini E.

Dr Pepper to Make Good on Chinese Democracy Stunt

By Eliot Van Buskirk

GunsnrosesSoda manufacturer Dr Pepper promised a free soft drink to everyone in America if Guns N' Roses releases its long-awaited Chinese Democracy album before the end of 2008.

Now that Axl and company have set a release date of November 23, Dr Pepper says it will make good on the offer. Those who want to claim a free soda can go to the Dr. Pepper website on November 23, enter some personal information and get a coupon for one 20-ounce drink that should arrive within the following 4 to 6 weeks. (The offer strangely said no free soda for former GNR members Slash and Buckethead.) The freebies expire in February 2009.

The band didn't know about the promotion until it was announced in March 2008. When he heard about the proposed giveaway, Axl Rose explained: "We are surprised and very happy to have the support of Dr Pepper with our album Chinese Democracy, as for us, this came totally out of the blue. If there is any involvement with this promotion by our record company or others, we are unaware of such at this time. And as some of Buckethead's performances are on our album, I'll share my Dr Pepper with him."

The "Chinese Democracy" single went online yesterday (you can listen to the whole song here and then rate its rockingness in our poll).

Corvette ZR1-- Incredible yet Flawed




Chismillionaire's Take:

Looks real fast. Incredibly fast even on video. I mean the slalom(74 mph!!!) was like on fast forward wasn't it? 1.06g skid pad, 96ft 60-0mph time after time. However as soon as the guy pushed the back bumper and the thing gives like Paris Hilton's Crotch and you can see the seats are standard issue Corvette sans any bolstering!!!- no I say.

Not for my 118 Grand. Instead get a new Audi R8, a used Aston DB9, a 911 Turbo with PDK shifter or Nissan GTR. A High Mileage Ford GT even. Lots of better options. A great effort though in this economy and market. Tip of the cap to the General.

Note: If you look around, you can get 10 Grand off right now on a new Z06 making a 427ci 505hp track monster available for 63 grand out the door. Not bad.

What I do like is, this engine detuned slightly sans titanium internals and dry sump in the lovely styled and sumptuous interior of the CTS V priced at 60 with super supportive power Recaros. Eat your heart out C/E63


Brute force, a quality we can't help but assign to any car generating 638 horsepower, is by definition anything but subtle. Yet the 2009 Chevy Corvette ZR1 manages at once to be both brutally quick and remarkably mild-mannered. Its quarter-mile acceleration is quicker than any production car we've ever tested, its chassis is benign but highly capable and its carbon-ceramic brakes are mind-bending in their effectiveness. This new Vette offers an unlikely combination of performance and real-world usability that we're proud to experience in an American car.

This combination is as rare as truth in a presidential debate. Honestly, most of the ZR1's competition (think Dodge Viper ACR) or Nissan GT-R)) is less capable and makes a much larger compromise in typical road driving. With the 2009 Chevrolet Corvette ZR1 we have a machine that is engaging to drive, capable of making insane numbers on the test track and also a legitimate road car.

Insane Numbers
We hit the track early in the morning with the Corvette ZR1 when the temperature is low and barometric pressure is high — an ideal combination. The corrected results (which are slightly slower than the numbers the car actually runs) are truly impressive. The 60-mph mark arrives in 3.8 seconds (3.5 seconds with 1 foot of rollout like on a drag strip). The quarter-mile disappears in 11.5 seconds at a staggering 128.3 mph.

The last Dodge Viper ACR we tested hit 60 mph in 3.7 seconds (3.4 seconds with 1 foot of rollout like on a drag strip) and completed the quarter-mile in 11.6 seconds at 124.2 mph. The less-powerful Chevrolet Corvette Z06 is only marginally slower at 3.9 seconds to 60 mph (3.6 seconds with 1 foot of rollout like on a drag strip) and does the quarter in 11.7 seconds at 123.2 mph.

The Inside Line records continued to fall as we moved on to our handling tests. In direct contrast to the Z06, the ZR1 is stable, communicative and easy to control on its way to a 74.7-mph pass through the slalom. This is the second-fastest slalom speed we've recorded from a production car, behind only the Porsche 911 GT3 RS at 75.3 mph.

The skid pad performance is even more outrageous. There's massive stick, but the rear end refuses to step out unless you purposely make big stabs at the throttle — and then the back of the car slides predictably and controllably. The result — a 1.06g average in both directions (our standard) with a peak reading of 1.1g — is second only to the Dodge Viper ACR.

The ZR1 brakes to a halt from 60 mph in 96 feet, which ties this Chevy with the $198,875 Porsche 911 GT2. Chalk this up to Brembo carbon-ceramic brake rotors and massive fixed calipers (six-piston front, four-piston rear).

The Power
By now you know all about the ZR1's all-aluminum LS9 power plant. You know that it's supercharged and intercooled and that it displaces 6.2 liters. You know that it's assembled by hand. And you know that it's rated at 638 hp and 604 pound-feet of torque.

About the only thing you don't know is what 638 hp feels like in a 3,366-pound Corvette. But we do. And it's spectacular. Spectacular like Jessica Biel in Blade: Trinity (underrated movie, actually). Spectacular like Kate Bosworth in Blue Crush. Spectacular in so many ways that any real man will find it wholly irresistible.

Certainly we did.

First, slot the six-speed transmission's shifter into gear, a task it accomplishes with exactly the right blend of precision and fluidity. Then let out the twin-disc clutch with a few thousand rpm on the tachometer. Now find a freeway on-ramp you know well and prepare yourself. Lock your eyes down the road as far as you can see and relax your head against the seat headrest with its ZR1 logo. Then wood the throttle and start grabbing gears. In less than 10 seconds you'll be traveling 120 mph. And you'll still be in 3rd gear.

The ZR1's thrust is so awesome we decided to visit Harman Motive in Torrance, California for a few runs on the company's state-of-the-art Mustang chassis dyno to see just how much power the Vette gets to the road. After three dyno runs, power peaks of 505 hp @ 6200 rpm and 494 lb-ft of torque @ 4200-4300 rpm were recorded. That's right, it makes over 500 hp at the wheels.

But that's not the best part. Check the dyno sheet, the Vette's torque curve is shaped like a perfect dome, no dips or flat spots. And you can feel that when behind the wheel. This car makes redamndiculous power from idle to redline.

Sensitive Side
Drive a ZR1 and you learn to respect its ability to warp your perception of space and time. We did, but then something funny happened — we drove off the track and into the world. You know the world. It has features like ruts and potholes, rain grooves and debris. The world is a far cry from the perfectly flat, perfectly smooth track. The world, it turns out, isn't all that different from the streets around Detroit or the rural roads around the NĂĽrburgring where the ZR1 was developed.

This is a good thing. The more we drove, the more convinced we became that GM's engineers know a thing or two about ride control. And that their choice to use Magnetic Selective Ride Control — a technology that can adjust damping 1,000 times per second — is a good one. MSRC tames the ZR1's chassis to offer both a compliant and controlled ride and world-class handling — a compromise only Porsche has come close to matching, and then only at a much higher cost.

We weren't able to discern a significant difference between the two MSRC settings (Sport and Tour) on the highway. Both seemed to offer very good ride quality.

Brutal but Communicative
Part of the ZR1's magic is its rubber, as Michelin Pilot Sport 2 tires are found at all four corners. And GM has pulled no punches when applying the bigger-is-better philosophy here, as the tires measure 285/30ZR19 in front and 335/20ZR20 in the rear. The ZR1's front wheels are 10 inches wide; its rears are 12.

Accordingly, when cornering forces build, there's no shortage of dynamic information coming to you through the chassis. The lack of same has been our primary criticism of the Corvette Z06 (actually, we've found the car to be pretty unlikable). Sure, the Z06 is fast and it makes good numbers, but driving it hard always provides a thrill that feels like a flirtation with death and disaster.

Not so in the ZR1.

Three hundred and thirty-five millimeters of Michelin rubber on the road at each rear corner is almost enough to rein in 638 horses. In fact, the rubber combines with immensely tall gears to put power to the ground more effectively than we thought possible with so much power.

We say "almost" because there aren't any tires that can contain this Vette's enthusiasm for tire smoke when the throttle is used like a switch. But the ZR1 is easy to control, even when it's laying down two solid black stripes. Sideways. At 65 mph.

Noodly and Flabby
Here's the thing. The ZR1 is one hell of a car. No question. It matches or beats all of its rivals in virtually every performance test. And it's comfortable. But it's also a very, very expensive car. To be precise, our test car — which has both options, the $10,000 premium equipment package and the $2,000 chrome wheels — rang up a tab of $118,520. And this is at a Chevy dealer, remember.

One problem is that the 2009 Chevrolet Corvette ZR1 just doesn't feel special inside. Sure, the dash and doors are dressed up with leather, and they do look better than the standard Corvette's pieces. But the seats and steering wheel are the same pieces you'll find in a base Vette. And for nearly $120 grand that's not OK.

Even worse, those seats are flabby and soft. It's kind of like sitting on Rosie O'Donnell's lap, which might be fun since she doesn't make 638 hp. But it's distinctly not fun in the ZR1. Then there's the noodly-ass lever for the seatback adjustment that twists and flexes like a Twizzler every time we move the seatback. Seriously, this stuff is embarrassing in a $30,000 car and very much out of place in a car this special.

For what it's worth, our tester also leaked oil out of the gasket of its right cylinder bank and dripped it directly onto the exhaust manifold, periodically allowing the unmistakable stink of burning oil inside the cockpit. At highway velocities its steering wheel shook and shimmied like Shakira on speed. Then its left front tire pressure sensor failed. This, in turn, caused the ECU to reactivate the stability control system during testing, which was a hassle. But we're sure none of that will happen on customer cars.

So What
Given the trouble we've had with other supercars, our long-term Nissan GT-R included, the above issues seem relatively minor. Plus, relative to its adversaries from Germany and Italy, there's no denying the value of the 2009 Chevrolet Corvette ZR1.

The only question, then, is what to do with a 638-hp Corvette capable of annihilating its rivals with sheer brute force? We can think of one thing: How about surprising them with its mild manners?

ReWalk helps paraplegics stand upright, climb stairs

HAIFA, Israel - Paralyzed for the past 20 years, former Israeli paratrooper Radi Kaiof now walks down the street with a dim mechanical hum.

That is the sound of an electronic exoskeleton moving the 41-year-old's legs and propelling him forward — with a proud expression on his face — as passersby stare in surprise.

"I never dreamed I would walk again. After I was wounded, I forgot what it's like," said Kaiof, who was injured while serving in the Israeli military in 1988.

"Only when standing up can I feel how tall I really am and speak to people eye to eye, not from below."

The device, called ReWalk, is the brainchild of engineer Amit Goffer, founder of Argo Medical Technologies, a small Israeli high-tech company.

Something of a mix between the exoskeleton of a crustacean and the suit worn by comic hero Iron Man, ReWalk helps paraplegics — people paralyzed below the waist — to stand, walk and climb stairs.

Goffer himself was paralyzed in an accident in 1997 but he cannot use his own invention because he does not have full function of his arms.

The system, which requires crutches to help with balance, consists of motorized leg supports, body sensors and a back pack containing a computerized control box and rechargeable batteries.

The user picks a setting with a remote control wrist band — stand, sit, walk, descend or climb — and then leans forward, activating the body sensors and setting the robotic legs in motion.

"It raises people out of their wheelchair and lets them stand up straight," Goffer said. "It's not just about health, it's also about dignity."

Kate Parkin, director of physical and occupational therapy at NYU Medical Centre, said it has the potential to improve a user's health in two ways.

"Physically, the body works differently when upright. You can challenge different muscles and allow full expansion of the lungs," Parkin said. "Psychologically, it lets people live at the upright level and make eye contact."

Iuly Treger, deputy director of Israel's Loewenstein Rehabilitation Centre, said: "It may be a burdensome device, but it will be very helpful and important for those who choose to use it."

The product, slated for commercial sale in 2010, will cost as much as the more sophisticated wheelchairs on the market, which sell for about $20,000, the company said.

The ReWalk is now in clinical trials in Tel Aviv's Sheba Medical Centre and Goffer said it will soon be used in trials at the Moss Rehabilitation Research Institute in Pennsylvania.

Competing technologies use electrical stimulation to restore function to injured muscle, but Argo's Chief Operating Officer Oren Tamari said they will not offer practical alternatives to wheelchairs in the foreseeable future.

Other "robot suits," like those being developed by the U.S. military or the HAL robot of Japan's University of Tsukuba, are not suitable for paralyzed people, he said.
