He was one of the most accomplished American road racers of the last generation, with a career that lasted from the 1960s well into the 1980s. Tony Adamowicz, known affectionately as Tony A2Z, died this week after a long battle with brain cancer. He was 75 years old.
Adamowicz worked as a White House staffer for the Eisenhower, Kennedy and Johnson administrations when he suddenly got the urge to drive racing cars. His talent quickly became obvious – there were very few drivers in the world who could get more out of the unforgiving Porsche 911 than he could, and Adamowicz was rewarded with the Under 2.0-liter portion of the SCCA Trans Am championship in 1968. He also won a championship in Formula 5000 against world-class competition, and in a Ferrari 512, scored podium finishes in 24-hour contests at both Daytona and Le Mans.
Promoting the Formula 5000 series, circa 1973.
You can’t claim the guy didn’t have a self-effacing sense of humor. During the early 1970s, Adamowicz teamed up with racers Oscar Koveleski and Brad Niemcek to form the Polish Racing Drivers of America, a tongue-in-cheek organization of fans that’s still active today, and doesn’t require its members to be either Polish or racing drivers. The three PDRA amigos then shared a Chevrolet van in the 1971 running of the Cannonball outlaw race. The van was loaded with 55-gallon drums of gasoline, so the team could make the New York-to-California run without a fuel stop. In the end, they were beaten only by the winning Ferrari Daytona of Dan Gurney and the late Brock Yates.
Adamowicz, a New York native, remained highly active in the California vintage-racing scene until he became incapacitated by his illness.

In Corvette parlance, Z06 is shorthand for race-car-level performance wrapped in a street-legal package. The original Z06 package, circa-’63, was a backdoor entrance to the best competition gear Chevrolet had to offer. It wasn’t meant for privateer racers, not the average enthusiast, and was priced accordingly, adding about $1,800 to the base price of a $4,000 Sting Ray.
At the dawn of the 21st century, Z06 Corvettes reemerged as off-the-showroom floor, road-course weapons or the most capable corner-carving street cars, you’d ever set foot in.
Fortunately, after the 2001-’04 C5 Z06, the package didn’t go on hiatus for another 30-plus years as it had before. Instead, the 2006-’13 C6 Z06 raised the stakes higher. It was built on an all-aluminum platform with a lightweight magnesium engine cradle. Bundled in that cradle was a howling, thinly veiled race engine—the LS7 427. The next generation Z06, that arrived with the C7 Corvette, was a little more civilized. It used supercharging to boost power, an eight-speed automatic transmission was available, and a convertible was offered. This was the most popular version of the Z06 ever, selling nearly 40,000 copies in its five-model-year run. It also was the subject of a couple class action lawsuits. The first alleged that some 2015-’17 Z06s would overheat during track sessions, triggering the computer’s limp mode and sending the cars limping into the pits to cool off. A second lawsuit alleged that 2015-present Z06 (and 2017-present Grand Sport) alloy rims could warp, bend or crack leading to punctured tires, air leaks or blowouts.
For 2023, Chevrolet built the most technologically advanced and exotic Z06 to date. Starting with the mid-engine C8, engineers added the all-new LT6 “Gemini” engine: a 333-cu.in. (5.5-liter) flat-plane V-8 with dual-overhead cams and four valves per cylinder. The LT6 used modern race bits like: a two-piece aluminum block; forged titanium connecting rods; lightweight, short-skirt pistons; dry-sump oiling; titanium intake valves; sodium-filled, stainless exhaust valves; direct fuel-injection; and an active intake. All in, the engine made more than two horsepower per cubic inch at 8,400 rpm.
With the EV era upon us, what does the future hold in store for the legendary Z06? Hard to say, so instead let’s take a look back at the five amazing editions offered from 1963 to the present. Are you one of the Z06 faithful? Send photos and the backstory behind the corner-carving Corvette in your garage to mmcnessor@hemmings.com.
1963 Chevrolet Corvette Sting Ray RPO Z06
<p><strong>Price new:</strong> $6,518.20<br/><strong>Average Value Today:</strong> $382,500<br/><strong>Collectibility:</strong> ★★★★</p><p>Racing was the raison d’être of the Z06, with track-focused performance at this car’s heart. The first appearance of option code RPO Z06 was in the launch year of the Corvette’s second generation, the examples built with it limited to that single model year. While new-millennium Z06s would use the performance-enhancing formula of less weight/more power, the original Sting Ray with Regular Production Option Z06 wasn’t stripped out or given a unique engine: it featured a grouping of special heavy-duty brake and suspension parts that were aligned with the best-performing optional components, including the 360-hp, Rochester fuel-injected 327 V-8, four-speed manual transmission, and Positraction differential. This option was a rare sight, as it’s reported just 199 split-window coupes were so outfitted that year, 63 of those including the endurance-racing-ready 36.5-gallon fuel tank.</p><p>Z06s are widely considered the most coveted of all second-gen Sting Rays, even more so than later 427 big-block convertibles, because of their exclusivity. Even just considering 1963 models, Z06s typically trade hands for more than three times what a lesser-equipped Corvette brings. Depending on the source, “#3” average-condition retail book values for standard-tank versions of this car fall in the $295,000-$325,000 range, while “tanker” variants range from $425,000 to $470,000; classic.com says that all public Z06 sales (both small- and large-tank) in the past five years average just over $530,000.</p><p><strong><em>—Mark J. McCourt</em></strong></p>
2001-'04 Chevrolet Corvette Z06
<p><strong>Price new:</strong> $47,500 (2001) to $52,385 (2004)<br/><strong>Average value today:</strong> $14,850-$22,100<br/><strong>Collectibility:</strong> ★★★☆</p><p>When Chevrolet chose to build the ultimate performance Corvette for a new millennium, it brought the Z06 label back to life for the first time in 38 years, this time as a full-fledged model name. The choice was an appropriate one for the new coupe, which Chevrolet called "the lightest, quickest, most rigid, most agile production Corvette ever created." That's a lot of absolutes. How did they get there?</p><p>First, they set about paring away excess weight. Beginning with the robust, fixed-roof hardtop body, engineers specified thinner glass in the windshield and rear window, lighter wheels, conventional tires instead of run-flats, less sound-deadening material, a lighter battery, and more. They also specified an exhaust system made of titanium, a material nearly thirty times as expensive as steel, pound-for-pound. The net result was a loss of 38 pounds. </p><p>Power came from a revamped version of the all-aluminum LS1 V-8, designated the LS6, which made 385 hp with a hotter camshaft and higher-compression pistons, as well as a cylinder block designed for better crankcase breathing. Further tweaks raised the power 405 hp in 2002. A six-speed with Z06-specific ratios was the only transmission available. Bigger wheels (wrapped in Goodyear Eagle F1 SC tires developed for the Z06), an uprated suspension, and a second-generation Active Handling system helped the coupe develop an unheard-of 1<em>g</em> on the skidpad. Rear-brake cooling ducts were incorporated into the rear fenders, creating a signature Z06 styling cue.</p><p>Initially priced at $47,500, the Z06 cost just $7,025 more than a baseline Corvette coupe. Between 2001 and 2004, 30,413 examples would be built. As a result, they're not difficult to find on the market. We found 28 for sale at <a href="https://www.hemmings.com" target="_blank">Hemmings.com</a>, at prices ranging from $18,991 to $50,000. </p><p><em><strong>—David LaChance</strong></em></p>
2006-'13 Chevrolet Corvette Z06
<p><strong>Price new:</strong> $65,800 (2006) to $77,010 (2013)<br/><strong>Average value today:</strong> $9,625-$26,925<br/><strong>Collectibility:</strong> ★★★☆</p><p>With the C6 Z06, Chevrolet's engineers again raised the bar. No longer content with producing the world's fastest Corvette, they now took aim at the supercars of Europe, with performance goals that would rival the best of Maranello and Zuffenhausen. </p><p>As before, the project started with weight reduction. The Z06 rode on an all-aluminum chassis, rather than the heftier standard steel unit, marking the first time that a special model Corvette had gotten a unique frame. The use of carbon fiber for the floorboards, front fenders, and fender liners shed additional pounds, while cast magnesium was specified for the roof structure and engine cradle. The result was a curb weight below 3,150 pounds, right in Porsche Carrera GT territory.</p><p>Powering the Z06 was a new, 7-liter (427-cu.in.) LS7 V-8, a rev-happy unit that belted out 505 hp at 6,300 rpm, on its way to a 7,000 rpm redline. The specs of this engine are deceptively pedestrian; aside from titanium connecting rods and intake valves, this pushrod powerplant made its horsepower the old-fashioned way. A dry-sump system for the engine oil merely indicated the kind of g's the suspension could produce. To cope with the extra power, Chevrolet fortified the six-speed manual, the clutch, and the rear axle, and specified 325/30ZR-19 tires out back in place of the stock 285/35ZR-19s.</p><p>The result was a no-holds-barred performance car with a power-to-weight ratio better than the Lamborghini Murcielago, the Porsche 911 GT2, and the Ford GT. Chevy priced its new supercar at $65,800, about a third the price of a Ferrari F430. After a three-day test that included laps on the Nürburgring and at Spa, Car and Driver called the new Z06 "a car that exposes the majority of European sports cars for what they are: overpriced, underperforming snobs." A total of 27,995 Z06s were built between 2006 and 2013, and they're still riding the depreciation curve. We found more than 30 for sale at Hemmings.com, starting at $33,000.</p><p><em><strong>—David LaChance</strong></em></p>
2015-'19 Chevrolet Corvette Z06
<p><strong>Price new:</strong> $78,995 (’15 coupe)/$85,495 (’19 convertible)<br/><strong>Average value today:</strong> $41,600-$71,300<br/><strong>Collectibility:</strong> ★★★☆</p><p>When this model debuted for 2015, General Motors called it the most powerful production car the corporation had ever built. That qualifier came courtesy of the Z06’s supercharged 6.2-liter LT4 V-8 that funneled 650 horsepower (up 195 over the regular ’Vette) and an equal measure of torque through a 7-speed manual or 8-speed automatic. The Z06 would soon be eclipsed by a new 755-hp ZR1, but this was a more everyday usable supercar that could newly be had as a convertible, thanks to the C7 ’Vette’s inherently stiff aluminum frame. Those wanting to boost the Z06’s track ability could select the Performance package that upgraded the aerodynamics, brakes, and tires. Chevrolet knew the Corvette faithful love making their cars stand out, so for 2018 it offered the Carbon 65 Edition to celebrate this model’s 65th anniversary, each of the 650 Z06 3LZ-based units produced bearing a unique numbered plaque, special carbon-fiber components, improved equipment levels, and more. </p><p>Run-of-the-mill Z06s could be considered veritable bargains today, with coupes and convertibles having retail book values in the low-$40,000 range, and even the final, most highly optioned late examples said to be worth more than $30,000 less than the current model. Public sales paint a slightly different picture, though: As this goes to print, classic.com notes the lowest public sale price was $50,000 and the highest, $2.7 million… that being the last 2019 Z06, sold for charity. The website considers the C7 Z06 to be an appreciating Market Benchmark at $76,851. </p><p><em><strong>—Mark J. McCourt</strong></em></p>
2023-Present Chevrolet Corvette Stingray Z06
<ul><li><strong>Price new:</strong> $105,300 (’23 coupe)/$119,700 (’24 convertible)</li><li><strong>Average value today:</strong> $112,700 (new ’24 coupe)/$141,500 (used)</li><li><strong>Collectibility:</strong> ★★★☆</li></ul><p>Corvette godfather Zora Arkus Duntov long championed a mid-engine version of America’s enduring sports car, as such a design could offer the optimized handling dynamics, he sought for racing superiority. It took decades to arrive, but the 2023-’24 Stingray was worth the wait. The eighth-generation Corvette comes in removable roof-panel coupe and folding hard-top convertible forms, both of which can be had as a Z06. Zora would approve of this new-era Chevrolet flagship variant and its all-alloy 5.5-liter LT6 engine, although he might object to it only being available with an automatic. Still, that flat-plane-crank, four-cam V-8 eschews forced induction yet makes 670 horsepower at a rotary-like 8,400 rpm. The 2024 starting prices of these ’Vettes are $106,695 for the coupe and $114,195 for the convertible; 2LZ and 3LZ options bring comforts and luxuries, while the track-terror Z07 Performance Package adds active suspension, carbon ceramic brakes, Michelin radials, a tall wing, and more. </p><p>Interestingly, it may be cheaper to buy a new C8 Z06 than a used one; jdpower.com indicates the average price retail price for a ’23 Z06 1LZ with around 1,000 miles on the clock is more than $140,000. That’s nothing compared to the $1 million paid in April ’22 for the first retail-production 2023 Z06 convertible –sold via Barrett-Jackson to benefit the Thurgood Marshall College Fund– or the $3.6 million spent for 2023 Z06 70th Anniversary Edition VIN 001 at B-J’s January ’22 Scottsdale auction, which benefitted the Operation Homefront charity. </p><p><em><strong>—Mark J.
