During WWII many U.S. service men were stationed in England,
and while they were there a lot of them got the chance to drive the MG, the
Austin Healy, the Morgan and the Jaguar sports cars. The cars were small, light
and nimble, and the Americans thought they were fun to drive. After the war the
service men returned home with fond memories of the fun they had driving the
English sports cars. It didn’t take long before the cars were being imported
into the United States and they were selling as fast as they could be shipped
in.
The management at General Motors was on top of all of the
car activity that was happening in the United States and they saw an interest
in English sports cars. Until then there were no plans to make a sports car,
but in 1951 chief designer, Harley Earl, the man who invented the concept car,
decided to build an American sports car concept based on a Chevy to see if
there was some interest. He turned the project over to Robert McLean and told
him he wanted a small sports car that would sell for about the same price as a
normal sedan. The only way McLean could do that was to use off-the-shelf Chevy
parts, so he took a ‘52 Chevy chassis and modified it to a smaller 102-inch
wheelbase dimension. In an effort to improve the car’s handling, the engine and
transmission were pushed back in the chassis so that a 53/47 front-to-rear
weight distribution balance could be achieved. The only Chevy engine available
was a straight six so it was outfitted with higher compression, a performance
camshaft design and a tri-power intake manifold. The engine was developing 150
horsepower, which was much better then the four-cylinder engines used in some
of the English cars and comparable to some of the six-cylinder engines used in
others. Unfortunately the only transmission that could hold up to the stronger
six-cylinder engine was the Powerglide automatic transmission.
The stylists were working on the body design with input from
Harley Earl, so it started looking very smooth and stylish. Instead of looking
like a British car, this sports car would be totally American in design. In
fact, the car was so smooth for the time period that doing the body in steel
would be cost prohibitive, so the Chevy engineers wanted to build the body out
of Fiberglass, which was a new process at the time. The concept car was being
built for the 1953 New York Auto Show and was in development when the chief GM
engineer, Ed Cole saw it and fell in love with the idea. Before the car even
debuted, Ed Cole made sure it would be more than a concept. A meeting was
called to name the new car and during the discussions, Myron Scott, an
assistant advertising manager suggested “Corvette”. Everyone loved the name
because it sounded good and it was appropriate for the image of the car. A
Corvette is a small, maneuverable warship that was smaller then a destroyer but
equally lethal.
The concept car debuted at the New York Auto Show and it was
a big success. The body design was awesome when compared to the cars at the
show and a hot sports car was very desirable. All of the people at the show
wanted to know when they could buy one. It took some time to set up a special
assembly line to build the cars but after the engineering and logistics was
finished, the car was finally released in June 1953. The car went on sale, but
since the car was introduced toward the end of the model year, only 300 were
produced. The ‘53 model was only offered in Polo White, but in 1954 the
Corvettes were offered in Polo White, Pennant Blue, Sportsman Red and Black.
Production ramped up in 1954 and 3,640 were produced but the Corvettes weren’t
selling as expected. The selling price was $3,498 and that was $1,000 more than
the cost of a loaded Chevy sedan or hardtop. The Corvettes were great looking
cars but the comfort, handling and acceleration was not up to expectations.
Since the ‘54 Corvettes weren’t selling well, only 700 ‘55 models were sold,
and even though the cars were now available with V8 engines, most of cars being
produced were offered with six cylinder engines.
In 1956 the Corvette received a new body style that was
smooth and aggressive looking. Chevy also made advancements in their fiberglass
technology and the car quality improved. The Corvette was also made more
appealing by introducing an optional removable hard top so the car could be
driven in all weather conditions. In ‘56 all of the Corvettes had 265ci 210
horsepower V8 engines and the sales started increasing. Small improvements were
made to the chassis and the car’s acceleration was far better than that of the
six-cylinder, so the car sales increased. It would be interesting to note that
the same front suspension and spindles used on the ‘52 and earlier Chevy was
used for the Corvette and it didn’t Change until the new ‘63 Corvette was introduced.
The Corvettes were now available with a floor-mounted three-speed manual shift
transmission so they were more fun to drive. The ‘57 Corvette looked just like
the ‘56 but there were substantial engineering changes. The ‘57 offered a T-10
four-speed transmission and the engine size increased to 283ci. Now Corvette
buyers could select a 220 horsepower four-barrel engine, a 245 or 270
horsepower dual-quad engine or a 283 horsepower fuel- injected engine. The
fuel-injected engine was actually delivering a little more than 283 horsepower
but the marketing folks liked the one horsepower per cubic inch rating. This
was the first really hot Corvette and the sales showed the buyers favorable
response. Chevy sold 6,339 cars in ‘57 but only 1,040 were equipped with fuel
injection.
The Corvette body changed in 1958 and since this was the
automotive styling year of excess, that also carried over to the Corvette. In
general the car body design was nice and it incorporated dual headlights but
this car had some extras such as fake hood louvers that were dropped for the
‘59 model year. The ‘58 Corvette was also equipped with some powerful 283
engines and they included a 230 hp base engine, a 250 and 270 horsepower
dual-quad engine and a 290 horsepower fuel injected engine. The Corvettes were
becoming more popular every year and in 1958 9,168 were sold and it was the
first year the car was profitable. The 1958 body design and mechanical
offerings carried through 1960 with small trim changes.
Another body change was made in 1961 where the front was
similar to the earlier models, but the back was changed from the round design
to one with a ducktail that was the forerunner of things to come. The new
design carried over to 1962 with small trim changes, but the big improvement
was the new 327ci engine. The Corvette was offered with several engine options
in horsepower ranges starting with the base 250 horsepower engine. It was also
offered with 300, 340 and 360 horsepower with carburetion and the fuel
injection model delivered 375 horsepower. That horsepower was really more than
the old ‘52 style chassis was made to handle and that was obvious when you
drove a 375hp version and stabbed the throttle.
Since the Corvette was finally profitable, Chevy decided to
introduce a completely new body and chassis design in 1963, which was also the
10th anniversary of the Corvette. Bill Mitchell, with help from
Larry Shinoda, designed the new Sting Ray and it was a vast departure from the
previous Corvettes. Zora Arkus Duntov, an engineer that was working on the
Corvette from the beginning, worked on a completely new chassis that featured
four-wheel independent suspension for improved handling. The suspension was
also shortened to 98-inches. The engine options remained the same as the ‘62
model. The ‘63 Corvette also featured fake grilles on the hood and a split rear
window and that made them look great, but rear vision wasn’t good. The Chevy
enthusiasts loved the new Corvette and sales really took off. Chevy produced
10,919 convertibles and 10,594 coupes. The ‘64 Corvette was similar to the ‘63
but the hood vents were eliminated and the rear window was one piece. The big
change came in 1965 when the chassis received four-wheel disc brakes and later
in the year a 425 horsepower 396ci big-block engine became available. The ‘66
Corvette was similar to the ‘65, but the big-block engine size increased to
427ci. The ‘67 Corvette was the ultimate second generation body style with new
side vents, a 435 horsepower tri-power 427 engine and another tamer 400
horsepower 427 became available. Chevy also offered an L88 427 engine option
for the Corvette that was delivering 500 horsepower but Chevy claimed it was
delivering 430 horsepower to appease the insurance companies. The race rated
engine was only available in a stripped Corvette and only 20 were sold making
them very desirable today. The 427 Corvettes were distinguished by the
“Stinger” hood scoop and 427 emblems.
The ‘63 and ‘64 Corvettes had independent front suspension
but they were still equipped with drum brakes. Wilwood Engineering saw the need
for improvement so the company released a Front Disc
brake kit part number 140-11011 for the car that features a front hub kit
and Dynalite calipers. In 1965 Corvette introduced four-wheel disc brakes on
the Corvette and they were a big improvement. The brakes were good when they
were new but the calipers developed a problem of rust pitting in the piston
bores and then they would start leaking. Wilwood Engineering became aware of
this problem so a D8-4 caliper that is a direct bolt-on to the original brakes
was released and it features a forged billet aluminum body and it uses
stainless steel pistons so there is no chance of leaking. Since the Corvette
used the same calipers from ‘65 to ‘82 this kit will work on both the second
and third generation Corvettes. This brake improvement is perfect for Corvette
owners who want to keep the car original in appearance. If originality is not a
factor, Wilwood also makes two big brake kits for Corvettes. The Superlite
6R Big Brake Front Brake Kit part number 140-10616 features six-piston
Forged Superlite calipers and 13.06-inch rotors in the buyer’s choice of
slotted or drilled and slotted styles. The calipers are available in
Platinum-E, red or black powder coat. A similar
kit is also available with 14-inch rotors and this kit is part number 140-10617.
Wilwood also makes a Superlite
4R Big Brake Rear Kit part number 140-10472 that features four-piston
Superlite calipers in Platinum-E, red or black powder coat. This kit features
12.88-inch rotors in a slotted or drilled and slotted style. A similar kit is
also available with 14-inch rotor.
In 1965 Larry Shinoda designed the Mako Shark concept car
Corvette and it was wild. The public loved the futuristic design and it became
the idea for the new ‘68 Corvette, which was very similar to the concept car.
The new car had removable tops and a pop-out rear window so you could turn the
coupe into a car very similar to a convertible, but still retain the nice
appearance of the coupe. This was the first T-top car and all of the Corvettes
after this one had a removable top. The engine selections including the L88
were carried over to the ‘68 model, but the L88 remained a limited edition
engine option. The ‘68 Corvette had minor problems that were fixed when the ‘69
Corvette was released. Both of the cars were very similar in appearance and
engine availability. In 1970 the body had new side grilles and the 427 was
replaced with a 454 engine. The ‘70 model was also introduced with a strong
running LT-1 350 engine that featured 370 horsepower and came with solid
lifters for a high rev capability. The ‘70 Corvette was going to be offered
with an LS-6 and LS-7 engine option but Chevy never released either one. The
Corvette was only offered with a 390 horsepower LS-5 454 engine and the new
emission mandates may have stopped Chevy from installing the monster LS-7
engine. The LS-6 engine was used in the Chevelle so this was the first time that
a passenger car had a more powerful engine than a Corvette.
Throughout the ‘70s, the Corvette received small body
changes and the power decreased on all of the engines. The horsepower
calibrations also changed from gross ratings to net ratings so the horsepower
ratings seemed really low. The ‘75 and newer Corvettes were offered with a base
350 engine and a higher horsepower L82 350 engine, neither of which were
exciting in an effort to pass emissions regulations. In 1978 the Corvette
received a new tail with a large rear glass that looked nice and it provided
more luggage space. Two special models were also available, the Silver
Anniversary model and the Indy Pace Car edition. Another body change came in
1981 that gave the Corvette a very aggressive appearance but the power was
minimal. In fact in California the only engine available was a 305ci
small-block. In 1982 Chevy introduced a new Cross Fire Injected 350ci
small-block Chevy engine that met California emissions. The ‘82 featured a
front air-dam style spoiler, a small rear spoiler and it was available with
very nice looking alloy wheels. Another desirable feature was the rear glass
was hinged and opened for easier luggage loading. This year there was another
special edition model that became available.
The introduction of the ‘83 Corvette was late because it
took longer for the company to complete the engineering and design changes. The
new Corvette was a drastic departure from the previous model in design and
engineering. The new car featured an aluminum front and rear suspension system,
a unique chassis design and the front opened up in a clamshell design, which
made engine access easy, but repair work expensive if the car got into an
accident. The new Corvette ride and drive press release was held at the
Riverside Raceway in mid-‘83 and the new car was a big hit with the press.
During a presentation to the press there was a discussion about the car and one
of the journalists suggested that the car be called an ‘84 Corvette instead of
an ‘83 and the Chevy management executives that were there liked that idea, so
the new late introduction Corvette was now called the ‘84 Corvette. It would
also be interesting to note that a convertible was not offered for the new
model.
The ‘84 Corvette featured 16-inch wheels running gator back
tires, it was outfitted with very positive rack and pinion steering and the
dash display looked like a video game. The Cross-Fire Injected engine was
outfitted with new high-flow aluminum heads and that increased the engine horsepower
to 245. The car also featured a new overdrive automatic transmission or a
five-speed manual transmission. Corvette enthusiasts loved the new car and
Chevy sold 53,877 cars. The ‘85 Corvette was similar to the ‘84 model except
for the engine that featured a new Tuned Port Injection system that bumped the
horsepower up to 250. The big change for 1986 was the introduction of a new
Convertible model and it was used to pace the Indy 500. In 1989 the Corvette
was outfitted with 17-inch wheels and new unidirectional tires.
In 1990 the Corvette received a body revision and it was now
available with an LT-5 engine option. The Lotus designed, dual overhead cam
engine that was built by Mercury Marine was an all aluminum engine that
featured 375 horsepower. The special ZR-1 option also included widened rear
fenders that were housing P315/35ZR17 tires. The Corvette could go from 0-60 in
4.71 seconds and turn the quarter in 13.3 seconds at 110 mph. The engine was
great, but the price for the Corvette was $58,995, which was extremely high for
the time period. It was about $25,000 more than a regular Corvette. In 1991
some changes were made and the horsepower was increased to 405hp and
accordingly the price also jumped to $64,138. If the base price wasn’t bad enough,
the dealers added a premium price on top of that and some were selling for
$100,000. The LT-5 engine was discontinued in 1995 a year before the new
Corvette was introduced.
Wilwood Engineering introduced a brake improvement for the
1988 through 1996 Corvettes. The brake kit being offered is the Superlite 6R
Big Brake Front Brake Kit part number 140-8337 that features six-piston
Forged Superlite calipers and large 12.88-inch rotors in slotted or drilled and
slotted style. The big calipers are available in Platinum-E or red and black
powder coat.
A similar kit is also offered with large 14-inch rotors and it is Wilwood part
number 140-9298. Wilwood also offers a rear rotor update for the Corvette
that includes the rotors, aluminum adapter plates, brake pads, braided steel
hoses and the necessary hardware to make the change. The Wilwood part number is
140-8314.
The new 1997 Corvette was a big departure from the previous
models and this car featured a front mounted engine and a rear mounted
transmission to balance the front to rear weight distribution. The engine
options were also changed and the car featured an all aluminum LS-1 engine that
was developing 345 horsepower. This car also featured 18-inch rear wheels and
17-inch front wheels running unidirectional tires. The 1998 Corvette paced the
Indy 500 and a special model was available. In 1999 the Corvette received a
heads-up display that was projected on the windshield. A third coupe body style
was also offered in addition to the hatchback and convertible, but it was a
mystery why. Sales for the body style was very low but the mystery was solved
when the Z06 option was released and was only offered in the lightweight coupe
model. The Z06 featured a new LS-6 engine that was delivering 385 horsepower
for the 2001 model and 405 horsepower for the 2002 model year matching the
(LT-5) horsepower rating. In 2003 there was a special 50th
anniversary edition made available that featured a deep red color.
In 2005 the Chevy engineers wanted to design the ultimate
Corvette that uses all of the best features of the previous Corvettes and none
of the problems. It was also a goal to bring the price down on the car so sales
could be increased. The engineers started by making the car lighter, changing
the body design to look more aggressive and installing a new engine to make the
car faster than any of the previous Corvettes in base form. The Corvette
received a new LS-2 engine that develops 400 horsepower and 400 ft-lbs of
torque. It is interesting to note that this is net horsepower not gross so
today’s Corvette is developing more horsepower than any of the 427s in the early
years. The Corvette also received exposed headlights, the first since 1962 and
that was for a design feature and it eliminated the heavy mechanisms necessary
for hideaway headlights. The new base model Corvette does 0-60 in 4.2 seconds
and it turns the quarter in 12.6 seconds at 114 mph. The Z06 Corvette is still
available and the special engine is rated at 505 horsepower. This special
edition Z06 can go from 0-60 in 3.7 seconds and it turns the quarter mile in
11.7 seconds at 125 mph. The top-of-the-line Corvette the ZR1 features a
supercharger and the engine produces 638 horsepower. The ZR1 does 0-60 in 3.4
seconds and it turns the quarter mile in 11.3 seconds at 131 mph. Over the
years the Corvette has earned a reputation for being one of the ultimate American
sports cars and it all started in 1951 when a design legend wanted to have a
car that would compete with the English sports cars.
