I've driven a lot of Corvettes over the past 10 years. So many, in fact, that getting into one feels like putting on an old shoe. When you drive a new/different car on a regular basis you develop a mindset of opening the door, dropping into the driver's seat and cranking up the "So how does this one work?" thought process.
But when I get into a Corvette it's like hopping into one of my personal cars. Adjusting the driving position, tweaking the audio settings and utilizing the car's full performance capacity requires almost no familiarization time. Just get in and go.
The 2008 Corvette Z06 I drove over this past weekend was a welcome refresher course on everything that's good -- and not so good -- about the current Corvette.
Thankfully, the "good" list is longer and includes everything from the excellent (and highly configurable) driver's position to the "instant on" power streaming from the naturally-aspirated, 505-horsepower 427 c.i. V8. I actually had to recalibrate my throttle input when accelerating out of corners in the Corvette Z06 because there's essentially no delay between when you press on the pedal and when the car leaps forward. You want a wall of torque forever poised to strike on command? This car supplies it better than any other vehicle I've driven except, maybe, a Dodge Viper (yes, that includes the Ford GT, Nissan GT-R, Porsche 911 Turbo and any AMG product).
The car's responsive bursts of acceleration are undoubtedly aided by its featherweight status, with the Z06 putting less than 3,200 pounds of pressure on whatever pavement it's crossing. Now throw in Chevrolet's brilliant "Competitive Driving" mode in the Corvette's stability control program, as well as the powerful and progressive stoppers, and you have a lithe coupe capable of harassing any over-priced exotic on the planet, whether in a straight line or through a series of corners.
And did I mention the plentiful cargo space (22 cubic feet)? How about the econo-car like fuel mileage? Corvette's will pull mid- to high-20s in highway MPG with minimal driver restraint.
Yup, when it comes to the numbers you only have to cross the Z06's price with its horsepower, curb weight and track times to easily solve the equation and arrive at an answer: This car is a screaming bargain.
And if you're the "shop-by-spreadsheet" buyer there's little to question regarding the Corvette's performance potential.
BUT (you knew it was coming), if you delve beneath the numbers and analyze the car's finer points the picture isn't quite as clear. I'll list off the items, in order, that force me to qualify my "buy" recommendations on a Corvette (Z06 or otherwise):
1. Transmission: I keep hearing about "tweaks" to improve the "feel" and "quality" of the Corvette's six-speed Tremec transmission. It does indeed keep getting better...but it's still not good enough by 2008 supercar standard (yes, even supercar "screaming bargain" standards). For instance, I tend to like to leave my hand on the shifter when driving a high performance car, even when just cruising along PCH (and certainly when catapaulting between apexes on Mulholland). But the Corvette's shifter buzzes like a defective electric razor, making me want to avoid contact until absolutely necessary.
And shift action itself remains pretty much at the bottom of the barrel in today's crop of $50,000-plus performance cars. There are numerous aftermarket shifters that can improve the shift action, but fixing that buzz will likely require a complete revamp of the driveline's mounting system (and/or a completely new transmission). Choosing between this transmission and the increasingly common "F1" style transmissions on the Corvette's competitors isn't easy. I'd rather go for option "C" -- a well-sorted, traditional manual transmission (ala Audi R8, Ford GT or Porsche 911).
2. Dynamics: This one is harder to explain because, as stated previously, the Corvette has all the basics covered: lightweight body components covering an aluminum chassis riding on a double-wishbone suspension. These items certainly keep the Corvette Z06 on course when tossing it down a twisty road, but the feel of the car, like the transmission, isn't up to modern supercar poise. It's not overt, but subtle chassis shudders and minor steering wheel kickbacks are not uncommon.
What's most troubling is how these traits largely negate the car's leightweight technology. At less than 3,200 pounds the Corvette should feel like the lightest, most nimble coupe in the segment. It doesn't. Drive a Z06 back-to-back with an Audi R8 and you'll swear the 3,400-pound Audi is lighter. Even the somewhat tubby Nissan GT-R doesn't feel remarkably (let along 700 pounds) heavier than the Z06. There's a psychological element playing a role here as well, with the Corvette's large exterior dimensions and flaring front fenders in your forward view adding to the Chevy's "big" impression. Regardless, the Corvette doesn't feel as sporty as it is, which is a rather crucial element in a sports car if you ask me.
3. Scraaaaape!: The first modern Corvette I ever drove was a convertible C5 as part of a roadster comparsion test we did in the summer of 1999. In that test was an Audi TT, a BMW Z3, a Honda S2000, a Mercedes-Benz SLK, a Plymouth Prowler and a Porsche Boxster. None of them made any contact with the pavement as we snaked over backroads along the California coast between Los Angeles and Big Sur...except the 'Vette, which emitted loud scraping and grinding noises on anything but billiard-table smooth road surfaces.
Nine years and one generation later the highest performing Corvette still sweeps the pavement like a low-slung street cleaner. I've driven my Ford GT in and out of my driveway a couple hundred times without so much as a wisp of undercarriage contact. But every time the Z06 pulled in or out -- SCRAAAAAAAAPE!
Sometimes I wonder if Chevrolet wants the front spoiler to serve as a sort of "early warning system," alerting owners long before anything really important slams into the ground. Whatever the intended goal, the real-world result is a constant (and LOUD) reminder that Corvettes don't like real-world road imperfections. Somewhat contradictory for a car that otherwise prides itself on being the practical man's sports car.
4. HOT! HOT! HOT!: I first noticed this when I drove a 2006 Corvette Z06 from Monterey to Los Angeles a couple years ago, but I'd forgotten about the Easy-Bake Over effect from the car's drivetrain tunnel. Leave anything in the cupholders or center console, such as sunglasses, a cell phone or even the Corvette's own keyfob (easy to do because the car comes standard with keyless ignition), and you'll want oven mits when it's time to retrieve them. God forbid you leave a cold drink in there...
I don't know what's causing this heat issue, but like the transmission performance and suspension tuning, it compromises the Z06's pedigree as a full-fledged (and fully-sorted) supercar.
So what's the upshot? Do these items neutralize the Corvette's otherwise stellar performance? No, the car simply provides too much bang-for-the-buck for these issues to negate the value equation. I raise them not to discredit the Chevrolet's capabilities but to remind people (once again) that there's more to a car than just its performance numbers.
However, when I contrast the Z06's $71,000-plus price tag against the base Corvette's $46,000 I find myself leaning toward the base car. Put simply, you're getting 85 percent of the Z06's performance for 60 percent of the price. Additionally, the issues I mentioned above are much easier to forgive when the price tag is on the right side of $50,000.
In other words, if we're going to fixate on numbers (a common mistake made by performance car fans) the base car smokes the Z06.

Interesting post, though I'm sure it will generate some anger (as usual). I am always happy to see a post explaining why "shopping by the numbers" doesn't always make sense.
The cargo space and gas mileage are amazing, and definitely a big bonus for me. I would tend to agree with Karl that the base vehicle is more desirable to me. If I'm spending $70-80K +, I would rather try to get into something a little more exotic and certainly more head turning. If I was spending < $50K, it is a bit more appealing.

This further confirms my lust. What a deal. I've always loved Corvettes, but when the C6 first arrived, and the "base" model was better than the C5 ZO6, it hurt me to not buy one (darn kids... 22 cubic feet you say?... that could work)
It's somewhat disappointing to see your list of negatives, but wouldn't you say that it's still a thousand times more refined than the Ferraris and Lamborghinis of our childhood, or the first generation Viper? And at least as good or better than any other current American muscle car, such as one of the hopped-up Mustang variations, or the new Challenger?

I've never really seen the magic in Corvettes. I also have a ton of friends who go 'by the numbers' all the time to praise the Corvette as 'the best sports car'. But, after see how Karl laid it out, I would have to agree that a base Corvette is a great car for the money. The only thing that I really wish would change is the interior, it really needs an update. the leather package helps, but it is really expensive. Hmm...now I might add a low-mile, couple year old 'Vette to my weekly Autotrader\Carsoup search.

Karl, good review on the C6 ZO6. Is a great car and had the chance to compare both base and ZO6. You are right if you are looking for a supercar performance at bottom price the ZO6 is the car.
By the way watchout with the fuel mileage and treat that gas pedal gently. If you floor it too many times you gas mileage goes out of the window big time.
Sure the car has their bad points. The dealer was having a heck of a bad time trying to open the rear hatch. Sounds familiar? Avoid slow turns. You get a workout on your arms. Avoid pot holes at low speeds. The car just bottoms out.
As for a car choice, I hate to say this but is not just the difference on horsepower with the base corvette the engine on the ZO6 is a different animal. The base Corvette engine starves on top end like true old pushrod but the ZO6 keeps pushing. The front end on the base car feels unsettle at high speeds compared with the ZO6.
The only bad thing with the ZO6 is that the great majority will not notice you driving one. They think you are driving a base Corvette.

So pretty much you spent the whole post nit-picking a $71k "supercar"? Give me a break. The Z06 is NOT a "supercar". It is a car that can hang with the supers but at half (if not more) of their prices.
With that concept don't you think that something's going have to give?

FYI, I used to post under ewilfong, but I've re-registered under a new handle after being locked out from posting for weeks on end.
I don't consider any of the comments to be "nitpicking." Spending $71,000 on almost anything short of real estate creates fairly high expectations. And for me, those expectations include everyday driveability.

"But the Corvette's shifter buzzes like a defective electric razor, making me want to avoid contact until absolutely necessary."
That's actually a high tech device to remind you that, as any driving instructor will recommend, it's best to have both hands on the wheel when not shifting. You'll notice that the buzzing increases in intensity as RPM's increase - quite the innovative safety feature if you ask me.
In all seriousness, I wish the Vette had the Ricardo tranny that the Ford GT used, but there's probably a cost issue. On the plus side, people are adding significant HP and torque to their Vettes (via superchargers and turbos) without having to beef up the transmission.

Karl, thanks for the great article. It gives great insight into all the nuances of the Z06.
Personally, while I think Points 3 and 4 (the scrappy noise and heat problem) are unacceptable or very bad, I see Points 1 and 2 (the buzzing gear lever and the dynamic feel of the car) as issues that come with buying a "bargain supercar" and I don't think it'll matter much to the car's fanbase.
Karl, could you PLEASE post a similar article about the 2009 Mazda 6 in the near future? The full test on INSIDE LINE doesn't have any Second Opinions, but the 2003 Mazda 6 full test had your comments in the Second Opinions section.
Anyway, the Full Test suggests that the 2009 Mazda 6 is disappointing and I would like to know what your take on the car is.

"but the feel of the car, like the transmission, isn't up to modern supercar poise. It's not overt, but subtle chassis shudders and minor steering wheel kickbacks are not uncommon."
As many BMW and Mini owners can attest, ditching the runflat tires goes a long way towards helping this situation. Also if GM would use higher quality dampers and tighten the factory alignment tolerances it would make a world of difference. I'm curious to see how the ZR1 feels with its new Michelin tires (though still runflats) and aggressively-tuned magnetorheological dampers.

"Sometimes I wonder if Chevrolet wants the front spoiler to serve as a sort of "early warning system," alerting owners long before anything really important slams into the ground."
Good question - fortunately the front spoilers are basically disposable and are cheap to replace. On my coupe, I've found that I had to replace the 2 corner pieces (the spoiler is 3 pieces) after roughly 15,000 miles of commuting on speed hump and dip riddled roads. The total cost was roughly $25 and 20 minutes in my driveway. Supposedly the very low spoilers help keep the nose of the car planted at autobahn speeds. Unfortunately, I don't have any first hand knowledge of this.

"I don't know what's causing this heat issue"
The exhaust pipes run directly underneath the center console. I suppose some insulation would help, but that would add weight - and who needs that? If the plastic interior isn't melting, it can't be that hot, right?
I've got almost 22k miles on my C6 and I've yet to recieve any burns that require medical attention. I do make it a point to keep elecronics and microwave popcorn out of the center console, though the cupholders don't get too hot if you leave the cover open.

I'd reckon the R8 and GT-R feel nimbler due to the front end bite provided by their AWD systems. I think they are narrower in width as well.

For several reasons, I chose a “base” Corvette Coupe almost 2 years ago. One ‘number’ of interest to me was the Coupe’s price.
While I do indulge in ( um ) spirited cornering on occasion, I try to stay within 7 or 8 tenths at all times, on public roads – and my impression is that the base Corvette ( with ‘base’ suspension, not Z51 ) is well sorted, competent, and provides a rather amazingly good ride – for a sports ( or GT ) car as low as this.
I do scrape that front spoiler lip exiting my driveway – every day. [ Mine is a Daily Driver. ] And I have learned to be careful whenever I must traverse sharply angled pavement intersections. The noise is annoying.
The trans. tunnel on mine does generate some warmth. From scanning various Corvette forums, this seems to vary by individual example.
With deals on left-over 2008s at GM Employee price plus 0.0% financing, this seems to be an excellent time to buy a Corvette – certainly better than Fall of ’06, when I purchased mine.
Of course, re-sale \ trade-in values have plummeted on used Corvettes in the past year – so, eventually, it will cost me a bit more than I had expected. Corvette depreciation has historically been better than most Domestics. Oh, well.
I do not regret my choice to buy this Corvette.
The dynamics ( including world-class acceleration ) I find very satisfying – every time I drive it.
Anyway - I do agree a ‘base’ Corvette represents a screaming bargain, at today’s actual transaction pricing. And in particular, the ability to equip one relatively stripped ( say, only the Z51 pkg ) all the way up to a more GT-leaning ( ? ) 3LT, with heated seats, HUD, etc – allows it to appeal to both those preferring a relatively “pure sports car” & those ( like myself ) who want a GT car that can perform mundane chores & commuting, haul my Daughter & a long weekend of luggage 6+ hours to The Beach, etc.
There is even now a 4LT package available, with an additional layer of interior luxury.
I have found ( in nearly 30,000 miles – covered in about 20 months ) the ‘base’ Corvette to be a remarkably well-conceived, and now ( third year of production, when I purchased ) well-sorted GT car. Equipped with the amenities included in the 3LT package, and with the ‘base’ suspension, I have no problems driving in & out of MidTown Hotlanta every work day, highway driving as long as the gas tank capacity, my bladder & my thirst for coffee allow, or driving to the local grocery store.
In fact, as my only vehicle, I chose the Corvette largely to add a degree of enjoyment to all those mundane trips I typically have to make, each week.
Cheers,
- Ray

The thought process in choosing different versions of the same car is interesting. I think that in those cases, when someone is wondering whether the more expensive version is worth it, they've already decided on that nameplate, whether it's the Corvette, 3-series, 911, Mustang, or Civic, usually because of brand loyalties or styling preferences. How important is it to have the really fast version?
I doubt logic even enters the equation, it's a matter of bragging rights (or the opposite). Take the Camaro - the V6 version will have about as much power as the Mustang GT, and about as much as most people could ever want. (After 300hp, more power is a diminishing returns sort of thing). But there's a V8 version out there so they'll fear having to spend the next few years explaining their purchase to people. 911 and Corvette buyers face the midlife crisis stereotype unless they get the Carrera S or Z06 versions. Not very fair, imo. The expensive versions of those cars could put you in the base model of something more interesting... of which there's also a better version, I'm sure. It takes some self-confidence to get the base (value) model.

VERY interesting article about the Vette. The last Vettes I drove were 2 C5 Z06s. One was modified (usual I/H/E - ECU tweaks) the other was stock.
I can really relate to points #1 and #2 as the shifter feel wasnt pleasant in any situation. Its like driving my grandfathers old 1977 Chevy farm truck. It needs to have a precise, direct, light shifting action like an S2000 or something similar. On top of that the constant vibrations dont make it better. It was to the point of me not wanting to shift at all, good thing there was a plethora of toqrue on hand.
As the author stated the Corvette actually feels larger than it really is. It drives like a bigger car. Its wide and I didnt really enjoy the driving position. The seats were a bit chintzy too.
The car to me didnt have any finesse or that certain tactile feel that really connects me with a performance car. Although the chassis composure is pretty decent the chassis nor steering never seemed to talk to me. The Vette is a great car especially for the money but I prefer a much more tactile driving experience.
----------
These are the main reasons I bought our 2002 S2000 back in 2005. Its light and it feels light. It has that certain amount of tactile performance that a lot of high performance cars no matter what the price lack. The shifter feel, steering, clutch take-up, driving position and the immediate direct undiluted feel from the chassis just seems so natural,.... raw yet super refined and smooth. For the money I dont think there is another car that can match it in terms of that tactile driving experience. Then there is the sound (Corvette certainly sounds great too) of that 9000RPM redline. Simply glorious as it never seems like its even trying. Refined and smooth from idle all the way to 9 grand!
Turbo S2000 =) This particular S2000 dynoed @ 480hp and around 290lbft of torque (pump gas). Stock internals as the internals in the F20/F22 inline 4's are forged, super strong. Ive seen these 2.0/2.2L engines push out a bit over 600WHP on race gas with stock internals and stay together.

The value issue as relates to base vs Z06 is the same as it is for many high end cars. Is the M3 really worth the premium over the 335i? Probably not. At a certain point you are paying a premium for the exclusivity and performance potential of a top level car. The base C6 is more than fast enough for most folks but that doesnt mean people arent willing to pay more just to know they have a 505hp Z06.
The tunnel heating issue was addressed after the first model year. C&D said the 2008 tranny was much better after the tweaks. At least it was on the base car. Same goes for steering feel.
I would think that a heavier car is likely to feel more planted than a lighter car. The vette may feel somewhat twitchy and light on its tires compared to an R8 or GTR because its hundreds of pounds lighter.

The tunnel heating issue is by no stretch of the imagination resolved. Can't put anything in the cupholders, in the passenger footwell or in the trunk without it getting baked. And I don't mean slightly warm, either--those areas get downright hot.

"I would think that a heavier car is likely to feel more planted than a lighter car. The vette may feel somewhat twitchy and light on its tires compared to an R8 or GTR because its hundreds of pounds lighter."
1487, I dont think you understand what we mean when we say it drives like a bigger car or it feels heavier than it really is. Remember he said the Vette felt heavier than the R8 not the other way around.
Karls quote:
"Drive a Z06 back-to-back with an Audi R8 and you'll swear the 3,400-pound Audi is lighter. Even the somewhat tubby Nissan GT-R doesn't feel remarkably (let along 700 pounds) heavier than the Z06. There's a psychological element playing a role here as well, with the Corvette's large exterior dimensions and flaring front fenders in your forward view adding to the Chevy's "big" impression. Regardless, the Corvette doesn't feel as sporty as it is, which is a rather crucial element in a sports car if you ask me."
In other words the Vette feels like it weighs more as it isnt as alive, tactile or sharp as some of its heavier or lighter competition. Then there is the psychological element that Karl spoke of with the fenders and the larger exterior dimensions.
If you could drive a Porsche GT3 and a Z06 back to back you could better understand what we mean. The GT3 by contrast just feels light and alive in your hands and with any slight tug of the wheel the car responds RIGHT NOW! The 2 C5 Corvettes I drove although great performance, cars werent as alert and felt a bit numb. Im sure the C6 Corvette is better but I dont think its still up to par in this area given the similar articles Ive read.
With my (limted) experience with high powered high performance cars or performance cars in general if the car is tactile, repsonds quickly, feels light yet stable it gives the driver the confidence to push the cars limits and my own limits further.
If Chevy could sharpen up the Vettes responses, up the refinement, give this car the shifter feel it deserves, as well as steering feel befitting a car of this caliber this car would be near perfect as the overall driving experience would be much better. Add to that its overall performance......lethal combination.

the shifter and steering were upgraded for 2008 and all the reviews I read said the improvements were very noticeable. In fact, some reviews said the steering changes were more significant than the additional power. Considering the price point of the C6/Z06 I cant say that I'm surprised that it doesnt drive quite as well as a $120k R8. Are you surprised? I would hope the extra $50k would net the owner some sort of handling and refinement advantage. If Chevy built a Corvette that felt and drove like a GT3 or R8 it would probably cost a lot more than $45k.
