The 1978 Chevrolet Corvette marked twenty-five years of America’s sports car, and Chevrolet gave the occasion a genuine restyle rather than a badge. The flat rear window and flying-buttress pillars of the previous decade were replaced by a fastback dome of glass, transforming the profile, improving rearward visibility, and adding real luggage space behind the seats. Every 1978 carried 25th Anniversary emblems, and two special editions were offered: the two-tone Silver Anniversary and the Indy 500 Pace Car Replica – the first time a Corvette had ever paced the race. At 46,776 cars, 1978 became the best-selling C3 of all.

Overview and History
By the mid-1970s the C3 Corvette had changed very little. Emissions regulations had blunted performance, the convertible had gone, and the car had coasted through 1974 to 1977 with only detail alterations. The shape introduced in 1968 was approaching its tenth year.
1978 was the moment to act, because it was the Corvette’s 25th anniversary – the model had entered production in 1953. Chevrolet responded with the most significant restyle the third generation ever received, centred on an entirely new rear window treatment, and backed it with two commemorative editions and the Corvette’s first appearance as Indianapolis 500 pace car.
The commercial result was emphatic. Chevrolet’s overall car sales reached 2,341,035 for the year, and 46,776 of them were Corvettes – making 1978 the best-selling year of the entire C3 generation.
The Fastback Rear Window
The defining change is at the back. Gone was the flat rear window flanked by flying-buttress sail panels that the Corvette had used since 1968; in its place came a large domed fastback rear glass wrapping around the rear quarters.
The inspiration is clear – the shape recalls the C2 coupe of the mid-1960s – and the benefits were real rather than cosmetic:
- Improved rearward visibility, a long-standing C3 complaint
- More luggage space behind the seats, with a retracting cover for shade
- A cleaner, more flowing profile
One limitation is worth knowing: the glass did not open. It was a fixed window, not a hatchback. Access to the enlarged cargo area was still from inside the cabin. The first Corvette with an opening glass hatchback was the limited 1982 Collector Edition, with the C4 making it a general production feature.
The Silver Anniversary Edition
Every 1978 Corvette carried 25th Anniversary emblems on the nose and the fuel filler door. Beyond that, buyers could order the Silver Anniversary Edition, option code B2Z.
It consisted of a distinctive two-tone paint scheme – Silver Metallic over Charcoal Silver on the lower body, divided by a pinstripe – together with sport mirrors and slotted aluminium wheels.
An important point frequently misstated: production of the Anniversary Edition was not limited. It was a paint option rather than a numbered series, and 15,283 Corvettes were eventually sold with it – roughly a third of the year’s output. It is therefore considerably less rare than the Pace Car and should be priced accordingly.
The Indy 500 Pace Car Replica
1978 was the first time a Corvette paced the Indianapolis 500, at the 62nd running of the race, with retired former winner Jim Rathmann at the wheel. The actual pace car used the L82 engine.
Chevrolet built the Limited Edition Indy Pace Car Replica for sale, and it is the more collectible of the two 1978 specials. Its features:
- Black over silver two-tone paint separated by a red pinstripe
- Its own vehicle identification number sequence, separate from standard cars
- Silver leather or cloth seating, a leather-wrapped steering wheel, unique door trim panels
- Mirrored glass T-tops as standard equipment
- Sport mirrors, slotted aluminium wheels, white-letter 60-series Goodyear radials
- An extensive standard option list: power windows, power locks, rear window defogger, air conditioning, heavy-duty battery, AM/FM with 8-track, power antenna, dual rear speakers
The production story is the interesting part. Chevrolet originally planned a run of 2,500 replicas. Dealer demand – driven by instant-collectible speculation – pushed that to a target of one car per dealership, roughly 6,000. By race morning orders had already reached 6,500, and final production settled at 6,502 cars at a price of $13,653.21 against a base Corvette’s $9,351.89.
The speculation did not pay off as buyers hoped. So many were stored unused that low-mileage examples remain relatively available, which has kept values more modest than the original hype implied.
Engine Lineup
All 1978 engines were 350 cu in V8s with four-barrel carburetion. Performance was modest by the standards of a decade earlier, a direct consequence of emissions controls:
- L48 350 – the base engine, 185 hp, up slightly from the 180 hp base of 1977
- L48 350 California emissions – 175 hp
- L82 350 – the optional high-output engine, 220 hp at 5,200 rpm, and the engine fitted to the actual Indy pace car
The L82 is the one to look for. The difference between 185 and 220 horsepower matters in a car weighing around 3,572 pounds, and L82 cars command a clear premium today.
Transmissions and Chassis
Transmission choices were a four-speed manual or a three-speed automatic, with the automatic by far the more common in this era. The chassis carried over the C3 fundamentals: independent rear suspension, four-wheel disc brakes, and a 98-inch wheelbase, with overall length at 185.2 inches.
Shipping weight was approximately 3,572 pounds. The combination of that weight with 185 or 220 horsepower explains why the 1978 is a pleasant touring car rather than a quick one, and why these cars are valued for their looks and their comfort rather than their performance.
The 1978 also brought a revised interior and a number of detail improvements alongside the new bodywork.
Interior and Equipment
The 1978 interior was revised along with the body. The enlarged area behind the seats, made usable by the new rear glass, came with a retracting cover – a small but genuinely practical addition to a car that had never offered much luggage space.
Options included removable glass roof panels (RPO CC1, $349, fitted to 972 cars), cruise control, twin outside rear-view mirrors with remote adjustment for the driver, a heavy-duty battery, and a range of audio systems including AM/FM with 8-track or, for an additional $170, AM/FM stereo with CB radio.
Production and Pricing
- Total production (all coupes): 46,776 – the best-selling C3 year
- Silver Anniversary paint (B2Z): 15,283
- Limited Edition Pace Car replicas: 6,502
- Removable glass roof panels (CC1): 972
- Base price: $9,351.89
- Pace Car Replica price: $13,653.21
There was no convertible in 1978 – the Corvette had been coupe-only since 1976 and would remain so until 1986.
Telling the Three Versions Apart
Because 1978 has three distinct presentations, it helps to separate them clearly:
- Standard 1978 Corvette – any factory colour, with 25th Anniversary emblems on the nose and fuel filler door. Every 1978 has these.
- Silver Anniversary Edition (B2Z) – two-tone silver over charcoal silver with a dividing pinstripe, sport mirrors, slotted aluminium wheels. 15,283 built; not a limited edition.
- Limited Edition Indy Pace Car Replica – black over silver with a red pinstripe, its own VIN sequence, mirrored glass T-tops, silver interior. 6,502 built.
The separate VIN sequence is the decisive check on a Pace Car claim, since the paint scheme and decals can be applied to any 1978. Note also that the decals were shipped in the car rather than factory-applied in many cases, so an undecalled Pace Car is not necessarily wrong.
Collectibility and Buying
The 1978 is among the more desirable later C3s, and the restyled rear glass is a large part of why. It gives the car a cleaner shape than the 1974–77 models while remaining far more affordable than the chrome-bumper cars of 1968–72.
Values run: Pace Car Replica at the top, particularly genuinely low-mileage examples, then L82-engined cars, then Silver Anniversary paint cars, then standard L48 examples. Because so many Pace Cars were stored rather than driven, exceptional low-mileage cars appear on the market regularly, which caps values.
Buying priorities: verify a Pace Car through its separate VIN sequence, not the paint; check for the L82 through engine codes if the premium is being asked; inspect the birdcage and frame for corrosion, the standard C3 weak point; and examine the fibreglass for previous repair. These are not fast cars, so buy on condition and originality rather than chasing performance.

1978 Chevrolet Corvette – Frequently Asked Questions
What changed on the 1978 Corvette?
The rear. Chevrolet replaced the flat rear window and flying-buttress sail panels used since 1968 with a large domed fastback rear glass wrapping around the rear quarters. It improved rearward visibility, added usable luggage space behind the seats with a retracting cover, and gave the car a cleaner profile recalling the C2 coupe. The interior was revised at the same time, and every 1978 received 25th Anniversary emblems.
Does the 1978 rear window open?
No. Despite its hatchback-like appearance, the glass is fixed. The enlarged area behind the seats is still reached from inside the cabin. The first Corvette with an opening glass hatchback was the limited 1982 Collector Edition, after which it became a general production feature on the C4.
Is the Silver Anniversary Edition rare?
No – this is the most common misconception about the car. Production of the Anniversary Edition was not limited; it was a two-tone paint option (B2Z) in Silver Metallic over Charcoal Silver, and 15,283 Corvettes were eventually sold with it, roughly a third of the year’s output. The genuinely limited car is the Indy Pace Car Replica.
How many 1978 Pace Car Replicas were built?
6,502. Chevrolet originally planned 2,500, but dealer demand driven by instant-collectible speculation pushed the target to roughly one car per dealership – about 6,000 – and orders had already reached 6,500 by race morning. The price was $13,653.21 against a base Corvette’s $9,351.89.
How do I verify a genuine Pace Car?
Check the VIN. Pace Car Replicas were given their own separate vehicle identification number sequence, which is the decisive evidence – the black-over-silver paint and red pinstripe can be applied to any 1978. Note also that the decals were frequently shipped loose in the car rather than factory-applied, so an undecalled example is not automatically incorrect.
How much horsepower does a 1978 Corvette have?
Three ratings were offered, all from 350 cu in four-barrel V8s: the base L48 at 185 hp, a California-emissions L48 at 175 hp, and the optional L82 at 220 hp at 5,200 rpm. The L82 was the engine fitted to the actual Indy pace car and is the one worth seeking, since the difference matters in a car weighing around 3,572 pounds.
Was 1978 the first time a Corvette paced the Indy 500?
Yes. Despite the Corvette already being in its 25th year of production, the 62nd running of the Indianapolis 500 in 1978 was its first appearance as pace car, with retired former winner Jim Rathmann driving. The Corvette has since been chosen to pace the race many more times.
Is a 1978 Corvette a good classic to buy?
It is one of the more appealing later C3s – the restyled rear glass gives it a cleaner shape than the 1974–77 cars while costing far less than a chrome-bumper 1968–72. These are touring cars rather than fast ones, so buy on condition and originality. Verify any Pace Car claim through the VIN, check engine codes if an L82 premium is being asked, and inspect the birdcage and frame for corrosion, the standard C3 weak point.
