Expert Review:New Car Test Drive
New Car Test Drive
Great American sports car still going strong.
Long prized for its high performance at an attainable price, the Chevrolet Corvette continues to be an object of desire for red-blooded Americans. The Corvette continues to give drivers the best bang for the buck thanks to its supercar performance, relative driving comfort and reasonable maintenance costs.
The current-generation Corvette was launched as a 2005 model and is the sixth generation or C6. The Z06 joined the lineup for 2006. The 2007 model year brought a new engine, the LS3 6.2-liter V8. Every year has brought more refinement. For 2012, there are no major changes but some important minor ones. Among them:
The 2012 Chevrolet Corvette gets a new steering wheel, redesigned seats with larger side bolsters and extra padding in the armrests. New options on all 2012 Corvette models include a nine-speaker Bose sound system. The Performance Traction Management system is now available on the 2012 Corvette Z06. Centennial Special Edition trim, in commemoration of Chevrolet's 100th anniversary, is available on both the Z06 and ZR1 with race-ready accessories, special graphics and other track-ready goodies.
The Chevrolet Corvette continues to offer one of the best power-to-dollar ratios around. The Corvette Coupe, which starts at about the same price as a midsize luxury coupe, is blazingly fast thanks to its 430-horsepower V8. The 6-speed automatic transmission with paddle shifters is geared for performance and responds quickly, but true enthusiasts with prefer to stick with the standard 6-speed manual.
The Corvette Convertible, which, like the Coupe, can blast from 0-60 mph in 4.2 seconds, will satiate drivers who crave an open-air roadster experience.
For performance junkies, the 505-hp Corvette Z06 will exhilarate on the track as well as the street. And for the ultimate expression of gratuitous grunt, there's the insanely fast ZR1, a limited-production iteration that boasts a 6.2-liter supercharged V8 that cranks out 638 horsepower and 604 pound-feet of torque.
When it comes to specs alone, most versions of the Corvette don't have any apples-to-apples competitors. Drivers who want high performance in a more practical package might consider the new 580-hp Chevrolet Camaro ZL1 (with the same engine as the Corvette ZR1). Or perhaps the Dodge Challenger SRT8 or Ford Shelby GT500. Those seeking performance with refinement and luxury should consider the Porsche Cayman or BMW M3. Those who want to put the top down might want to look at the BMW Z4 or Ford Shelby GT 500 convertible. A well-appointed Z06 finds a tough competitor in the Porsche 911, Nissan GT-R or Lotus Evora. And at more than $100,000, those dropping the dough for the ZR1 should also take a look at the new Mercedes-Benz SL-Class, the Audi R8, as well as the refined and well-appointed Jaguar XKR.
The 2012 Chevrolet Corvette is available in two body styles, Coupe or Convertible, with either a manual or automatic transmission. The Z06 and ZR1 models are available only as fixed-roof Coupes.
The Corvette Coupe ($49,600) and Convertible ($54,600) are powered by a 6.2-liter V8 with 430 horsepower. A 6-speed manual transmission is standard; a 6-speed Paddle Shift automatic ($1,250) is optional. An optional dual-mode exhaust system ($1,195) raises horsepower to 436 hp. There are four trim levels; 1LT, 2LT, 3LT and 4LT, with increasing levels of features.
The Coupe features a one-piece removable roof panel in body color or transparent plastic ($750); the dual-roof option ($1,400) includes both. The Convertible comes standard with a manually operated soft top; a power soft top, with a heated glass rear window, is standard on 2LT trim levels and above.
Standard features for the Corvette include leather seating surfaces, dual-zone automatic climate control with a pollen filter, power everything including seats, cruise control, tilt leather-wrapped steering wheel with redundant audio controls, remote keyless entry and starting, AM/FM/CD stereo with auxiliary input jack, XM Satellite Radio, auto-dimming rearview mirror with compass, automatic headlights, alarm, fog lights, xenon headlights, OnStar telematics, and P245/40ZR18 front and P285/35ZR19 rear run-flat tires on alloy wheels. The 2LT and above models add sport seats with adjustable lumbar support and side bolsters, plus Bluetooth connectivity.
Magnetic Selective Ride Control ($1,995) automatically switches from extra-firm to more comfortable touring settings with electronically controlled variable damping. The package now includes cross-drilled brake rotors that are also available as a stand-alone option ($500). These rotors are larger than standard (13.4 vs. 12.8 inches up front, and 13.0 vs. 12.0 inches in the rear), but not quite as large as the 14.0/13.4 front/rear rotors on the Z06.
Options include DVD navigation ($1,795), which comes with a USB port as well as the Bose audio and voice recognition. There are a variety of wheel options in a wide range of styles and finishes. The 3LT package for the coupe ($4,205) and convertible ($6,200) includes a head-up display, heated seats with position memory, a premium Bose stereo, a power telescoping steering column, and a universal garage door opener. The 4LT package includes the 3LT and adds custom leather upholstery on the top of the instrument panel, upper door panels, and console cover, as well as extra armrest padding, crossed flags seat embroidery and a special console trim plate.
The Centennial Edition package will get you a Carbon Flash metallic exterior, satin black wheels with red calipers, Magnetic Selective Ride Control, red accent stitching on seats and steering wheel and special graphics on the interior and exterior.
Corvette Grand Sport Coupe ($56,000) and Convertible ($59,600) are equipped the same as the base models but with wider-body styling to cover their wider track, racing-tuned suspension, and Z06-sized tires and brakes.
Corvette Z06 ($75,600) comes with a 7.0-liter V8 producing 505 horsepower, with dry-sump lubrication and coolers for the power steering pump, gearbox and rear differential. Beyond the engine, the Z06 package includes a host of high-performance components. The Z06 hardtop is fixed in place. Its brakes are upgraded, its tires are huge and it's offered only with the 6-speed manual transmission. Options include the Z06 Ultimate Performance package with ceramic brakes, painted calipers, Magnetic Selective Ride Control and enhanced cooling. The CFZ Carbon Fiber package ($3,995) features a black-painted carbon fiber roof, rocker panels, and splitter, plus a body-color ZR1-style spoiler. The 2LZ package ($2,665) includes a power telescoping steering column, heated seats, memory for the seats, mirrors and steering wheel, Bose audio, universal garage door opener, cargo net, and cargo cover. The 3LZ package ($7,170) has the 2LZ equipment plus power sport seats and a premium leather package similar to the 4LT. There is a variety of wheel choices, including painted aluminum and chrome finishes.
The Corvette ZR1 ($111,600) has a supercharged 6.2-liter version of the Z06 V8, utilizing an Eaton four-lobe supercharger. To deal with the additional stresses and loads, every appropriate piece of the engine has been upgraded. The ZR1 is available only as a coupe, and only with a heavy-duty 6-speed manual transmission. The ZR1 gets huge Brembo brakes, 15.5 inches in front and 15.0 inches in the rear, and made of special heat-resistant carbon-ceramic material. The tires are Michelin Pilot Sport 2 ZP run-flats, sized 285/30ZR19 in front and 335/25ZR20 in the rear; the rims are 10 inches wide in front and 12 inches in the rear. The ZR1 also has the lighter-weight aluminum chassis components of the Z06, and carbon fiber for the roof, hood and front fenders. In addition, the ZR1 hood has a transparent panel. A Centennial Edition ($4,950) is available on this model as well, and includes the same features as on the Z06 package.
Safety features that come standard on all models include dual-stage front airbags, side airbags, ABS, tire-pressure monitor, traction control and electronic stability control.
Low and sleek, the Chevrolet Corvette shows a bit of European flair. This sixth-generation Corvette, called C6, was introduced as a 2005 model.
From some angles, the Corvette is almost pretty. However, functional elements dictate the design and the result is a forward motion that implies performance. The lines of the bulging hood, the shape of the fenders, and the cat's-eye headlights all point forward to a subtle beaklike shape. A pair of fog lights flanks a wide air intake below.
Vents behind the front tires let hot air out of the engine compartment. The sculpted fenders, with sharp creases that sweep dramatically up to the planed rear deck, call to mind race cars as well as jet fighters. At the back, four round taillights recall Corvette's past and make the car look like an F-18 taking off in full afterburner mode. On the functional side, the optics of the reverse lights magnify the light they throw out to help when backing up in this beast. To move weight from the front to the rear, the transmission is mounted behind the seats and connected to the differential, rather than being attached directly behind the engine.
The Z06 is distinguished from other Corvettes by lots of subtle appearance tweaks, starting with the roof. It's fixed rather than removable, adding an extra element of structural stiffness for track driving. You'll never see a transparent roof panel on a Z06: it would add weight and increase the height of the center of gravity. To improve front-rear weight distribution, the battery is relocated in the rear cargo area.
In front, the Z06 has a wider, lower grille and a separate, unique air scoop above the bumper to shove more intake air under the hood. Its fenders are wider front and rear to cover massively wide tires and rims (the front wheels are 9.5 inches wide and the rears are fully 12 inches wide, or two inches wider than those on the standard Vette). In back, brake scoops are located in front of the rear wheels, the Z06 spoiler is slightly more prominent, and its exhaust outlets are wider, too (four inches in diameter at the tips).
Several Z06 body and chassis changes are not visible. The frame is made entirely of hydro-formed aluminum (the standard Vettes have steel rails), with a magnesium engine cradle, and its fenders are formed from ultra-light carbon fiber. As a result, and despite a heavier engine and drivetrain, the Z06 weighs only 3,175 pounds.
The ZR1 takes this further with its own features. A transparent section in the hood allows the proud owner to show off the engine without having to actually do anything except point, as if even that will be required, once one of these things gets parked in a crowd of Corvette enthusiasts.
Special 100-year graphics make the Centennial Edition distinctive while remaining tasteful, and black-on-black racing stripes put out a vibe of understated cool.
The Corvette cabin features premium soft surfaces, nice grain in the materials and elegant tailoring. The dashboard is finished in a soft material that feels rich to the touch. Real metal accents are used, but they don't generate glare. The electronics displays serve the driver without getting in the way.
The steering wheel is relatively small. It feels good in the hands and affords a good view of the instruments.
The seats are comfortable and fairly easy to adjust, though moving the manually operated backrest forward is a problem because your weight is invariably resting on it when you want to adjust it. Sitting in the Corvette evokes that feeling of sitting deep down in a massive machine. There's plenty of headroom and the windshield doesn't seem too close to the driver's face. Hefty side bolstering on the optional sport seats, even more so with those in the Z06, makes it more difficult to slide in, but the bolsters squeeze around the thighs and torso and hold the driver like Velcro.
The Corvette is available with a special two-tone leather package that adds leather upholstery to the top of the instrument panel, upper door panels, and console cover. The effect is a more elegant, higher end look than the Corvette has had in the past.
The instruments are big analog gauges, easy to read at a glance. The Z06 gets a unique cluster with more gauges, and the ZR1 has a supercharger boost gauge. The Corvette is, thankfully, devoid of a lot of digital readouts. One exception is the head-up display, which projects speed, rpm and even g-forces onto the windshield, a handy and entertaining feature. The upgrade Bose stereo system includes redundant controls on the steering wheel hub for most functions.
The outdated-looking navigation system and audio interface looks like it could be running Windows 95, however.
Cubby storage is decent. The glovebox is roomy and, in the Coupe, there is 22.0 cubic feet of storage space under the glass behind the rear seats. That's more than the trunk space in a sedan, with plenty of room for golf bags. You need to be careful when loading to avoid scratching the bodywork, however, and the liftover height is high; this is not a sedan or everyday hatchback.
There's no need to take the key out of your pocket to unlock the Corvette or start its engine. Simply walk up and pull the door handle. With the keyless start feature, sensors detect your key and unlock the door. Climb in, buckle up, and press the starter button. We're not sold on the benefits of keyless starting, however.
The Convertible's five-layer fabric top is available in three colors, and it offers power operation. The power top operates with a single-button control and completes its cycle in 18 seconds. An easy-to-operate manual top is standard. The Convertible looks good with the top up, and it looks terrific with the top down, with body-color trim that gives it a racy appearance.
The Convertible gives up some cargo capacity. It offers 11 cubic feet of storage with the top up, which isn't bad for a roadster, and 7.5 cubic feet with the top down.
The Centennial Edition features grippy seats with Alcantara and leather trim that look sporty and are comfortable and practical. The bucket seats and adjustable bolsters keep driver and passenger snug around corners. The heated seats that come with the 3LZ Premium Package, seem counter-intuitive to the race-inspired nature of this car.
The Chevrolet Corvette is a lot of fun to drive in any iteration. The LS3 V8 engine sounds great, and its low, throaty roar is accompanied by thrilling acceleration. Stand on the gas and even the automatic will chirp the rear tires when it shifts into second.
With 430 horsepower, the Corvette can accelerate from 0 to 60 mph in 4.2 seconds and cover the standing quarter-mile in 12.5 seconds. There's lots of torque at all engine speeds, and throttle response is very willing. This thing goes, and it boasts a top speed of 190 mph. We haven't experienced 190 mph, but on a tight racing circuit we found the Corvette easy to drive at speed.
The Corvette is happy cruising around, as well. It gets an EPA-rated 16/26 mpg City/Highway with the manual, 15/25 mpg with the automatic.
The 6-speed automatic and 6-speed manual are each appealing in their own right, so choosing between them comes down to priorities and personal preference.
The manual gearbox is so easy to use that we recommend it as a viable option for a daily driver. It shifts easily and the clutch is easy to operate smoothly. For fuel economy purposes, Chevrolet includes a mechanism that forces you to shift from first to fourth gear when accelerating slowly. We find this annoying, but adjusted to it. This fuel-economy strategy can be avoided by revving higher and waiting longer to shift. Fifth and sixth gears are both overdrives, again to improve fuel efficiency. Shifting through the gears is a lot of fun and it's easy to brake and downshift using the heel-and-toe method when approaching a corner (actually by braking with the ball of the foot and blipping the throttle with the right side of the foot). In short, it's a modern, easy-to-operate manual; we'd own one. Launch Control optimizes performance for full-throttle starts for all manual-transmission Corvettes by monitoring engine torque 100 times per second and maximizing available traction. As such, the system is capable of approaching a skilled driver's very best efforts, and does it with consistency.
The automatic transmission is the best choice for commuting in stop-and-go traffic and it gives up little to the manual in terms of performance. The Paddle Shift automatic offers manual shifting via steering-wheel levers and an electronic controller with more computing power than the typical PC had 10 years ago. The relatively close ratios offer good performance and smoothness by allowing the engine to run at optimal rpm more often. First gear delivers impressive acceleration off the line. Yet both fifth and sixth are overdrive gears, allowing quiet cruising and good highway mileage. If ever a sporting car were suited for an automatic transmission, it's the Corvette, with its big, torquey V8. The automatic does not sap all the fun out of driving the way automatics do in small sports cars with small engines. It's responsive to the driver's intent, shifting hard and fast when you're accelerating quickly, but shifting smooth and soft when cruising.
In the handling department, the Corvette is agile and easy to toss around, benefits of its light weight, trim proportions and refined suspension. The Coupe weighs a trim 3,208 pounds.
We liked the standard suspension and would not hesitate to order a Corvette so equipped. Ride quality is firm but quite pleasant, not harsh. It offers great handling, even on a racing circuit. There's almost no body lean when cornering hard. In short, the cheapest, most basic Corvette is a great car. There is no need to step up any further. But we're well beyond need here, so why stop here?
The Grand Sport package makes the Corvette more fun on a race track. It uses the standard powertrain, but has wider-body styling, a wider track and a race-tuned suspension. It also has wider wheels and mounts 275/35ZR18 tires in front and 325/30ZR19 tires in the rear, and has 14.0-inch brake rotors with six-piston calipers in front and 13.4-inch rear rotors with four-piston calipers. Those bigger brakes may stave off some brake fade. The manual transmission has specific ratios, and, with the automatic transmission, the rear axle ratio is specific. This combination delivers excellent grip in fast sweepers, with just the right amount of body lean. You will feel and hear bumps more, but it's quite livable. Around town, it will handle bumpy neighborhood streets well and not feel terribly harsh. Grand Sports are available with Magnetic Ride Control, and the package includes Goodyear F1 Supercar Gen 2 tires when ordered with a manual transmission.
The F55 Magnetic Selective Ride Control covers both ends of the spectrum, offering the best of both worlds; a very similar setup is used on Ferrari's most expensive models. The driver can switch between Touring and Sport modes, each of which adjusts shock damping automatically according to driving conditions. In the Touring mode, the suspension varies damping from very soft when poking along to something close to the Grand Sport's stiffness when driven hard; these adjustments in damping happen very rapidly. Touring mode felt a little softer to us than the standard suspension on a country road. It filters vibration well, but it verged on feeling a tad floaty in some situations. Switching to Sport mode raises the floor (but not the ceiling) in terms of firmness, so you feel road vibration more. Still, it's not harsh. All in all, Magnetic Selective Ride Control is a great setup. It comes with fade- and moisture-resistant cross-drilled brake rotors. Choosing between the standard and electronic suspensions is problematic only because it gives us a choice. If they gave us one or the other, we'd be perfectly happy, but true performance junkies will probably prefer the Grand Sport setup.
The brakes are smooth, progressive and easy to modulate. The Corvette is very stable under hard braking and it doesn't get unsettled when braking and turning at the same time. Be advised, however, that the engine has so much power that the rear end can break loose if the gas is applied too hard in a turn.
The Z06 has 505 horsepower from its LS7 V8, which displaces 7.0 liters, or 427 cubic inches, just like the famous 427 Vettes of the late '60s. Yet the original 427s were big-block engines. While the LS7 generates big-block torque (470 pound-feet), it's actually a small block V8, so it's lighter and much more compact than the original 427s. Yes, it's still an overhead-valve engine (as are all Corvette powerplants), and in certain respects it has more in common with a heavy-duty Silverado pickup than a Ferrari. Yet the LS7 is impressively tuned and highly refined. The Z06 features a host of racing technologies that enhance durability, including dry-sump engine lubrication and separate cooling systems for the oil, power steering, rear axle and 6-speed manual transmission.
The Z06 is a great supercar value: Zero to 60 mph in 3.7 seconds, 11.7-second quarter mile, top speed in the neighborhood of 200 mph, and capable of generating slightly more than 1g constant lateral grip, according to Chevrolet. These numbers surpass those generated by European sports cars that cost twice as much as the Z06 during clearance sales, and all but a handful of low-volume, $500,000-plus specials built in small workshops around the world.
Our 2012 Z06 Centennial Edition let out a satisfying, thunderous roar from the first touch of the pushbutton start. Its throaty growl was audible but tame at lower revs, then proportionately more raucous as the needle climbed on the tachometer. Acceleration in this mean machine invokes a tickle in the stomach akin to plunging down a freefall ride. Braking is equally heart-stopping; the ceramic cross-drilled Brembo rotors are impressive but are overkill for everyday driving. Make no mistake about it, this is a track car. And to use this any other way would be just silly. The Z06 suspension is about as stiff as they come, allowing the driver a succinct connection between the car and every pebble in the road. After a day driving in the Z06 Centennial Edition, even hopping into a sport compact car known for its performance and handling can feel akin to piloting a marshmallow.
The Pirelli Sport Cup tires on the Z06 Centennial Editon look like racing slicks and offered amazing grip when warm, making them a perfect choice for the track or the street on a hot summer day. For daily driving, they were precariously slippery when cold, making for a lot wheel spin off the line in cold weather. What's more, our urban driving had us picking rocks off the tread at the end of the day. And we didn't even think about taking this beast out in a rainstorm.
The carbon fiber splitter, which comes with the Carbon Fiber package, is so low on the Z06, we had to cautiously circumvent crossroads and driveways with anything more than a 5 percent incline. Parking lot curbs and restaurant valets proved to be challenging hazards.
Driving the top-of-the-line ZR1 hard has been likened to an exercise in trying to stay about two corners ahead of the thing. Chevrolet says it will accelerate from 0 to 60 mph in 3.4 seconds, from 0 to 100 mph in 7 seconds, with a quarter-mile acceleration time of 11.3 seconds at a speed of just over 130 mph, and continue on from there to a top speed of 205 mph. Perhaps most impressive is a claimed time for the somewhat-well-known exercise of 0-100-0: From a standing start, to 100 mph, and back to a dead stop. Chevrolet claims it will make that little endeavor in 12 seconds flat, which is far, far better than any ride you're going to find at an amusement park.
The ZR1 is extraordinarily quick from point-to-point on a race track, or getting down a curvy road. In all probability, the number of drivers in the world who could use as much as this car has to offer is not a very big number and would not include drivers who have not had some serious racing experience. If you use a car like either the Z06 or the ZR1 (or even the regular Corvette, for that matter) to anywhere near the edges of its capabilities, you are going very, very fast. The corners come up very quickly, the requirement for saving the situation becomes a difficult thing to do and the consequences of a mistake can be enormous. The ZR1 is not a car for the faint of heart or for those without the highest of skill levels. While it is possible for the Z06 and the ZR1 to be driven in a more sensible manner, these cars are simply too much for the street. Then again, that's part of the fun.
The standard Corvette is far easier to live with every day than either the Z06 or ZR1, with a smoother ride on rough roads and a lighter clutch pedal. And it has 430 horsepower.
The Chevrolet Corvette is the great American sports car. It's thrilling to drive and delivers breathtaking acceleration performance and exceptionally tenacious grip for braking and cornering. Yet it's fairly easy to live with and relatively easy to drive. The ultra-high-performance Z06 and Grand Sport models push the envelope for off-the-shelf production cars to incredible limits. For everyday driving, our choice is for one of the standard models.
