About Chevrolet Corvette


The Chevrolet Corvette is a super sports car, created by Chevrolet in 1953 . It is manufactured today by an exclusive factory in Bowling Green of General Motors . It was the first fully American sports car manufactured by an American company. It is also the car that has been in production for the longest time since 1953. It is also known to be “cheap horse” because it costs around 70 to 100 thousand dollars in its best version, which is a much lower value to competitors as Ferrari, Lamborghini among others, and has a similar performance and in some cases superior. The National Corvette Museumis a museum dedicated to the car, also located in Bowling Green, Kentucky . It was the first sports car entirely developed and manufactured in the United States by an American automaker. The  National Corvette Museum  is a “site” exclusively dedicated to the model, also located in Bowling Green, Kentuck (USA).

New Generation of Chevrolet Corvette

Currently, Chevrolet introduced yet another generation of the Chevrolet Corvette C7, being the version ZR1 the most powerful of all the sports division of the brand, with one engine V8 6.2-liter SuperCharger yielding more than 750 horsepower and higher torque 100kgfm. If in Brazil the Camaro is the most famous sport of Chevrolet in the United States, the biggest symbol of this segment for the brand is the veteran Corvette, also with the option of yellow color. The new generation was introduced last year to commemorate the model’s 60th birthday . She added the term Stingray – which had appeared in the second and third generations. “We always use this name when it comes to a special Corvette crop, as wine is,” explains Marcos Munhoz, vice president of General Motors in Brazil. The Z06 is the “new” Corvette, no one will be cooler than it in the range. In fact, you can say that it is “the” Chevrolet, after all, is the most powerful car ever made by the manufacturer. So much so, that brand executives say they find it very difficult that, in the near future, the ZR1 appears again, because they have already put all their knowledge into this model. Nothing more fair to do justice to the name Z06, emerged in the second generation of the car covers lifetime warranty.

Body of Chevrolet Corvette

They started with the tires, much wider than the Stingray tires. They are huge and sticky Michelin Pilot Super Sport 285/30 rim 19 in the front (1.5 more inches) and 335/25 rim 20 in the back (two inches more). The Z07 pack, more focused on the tracks, brings tires of Michelin Sport Cup 2 of very high performance. This made it necessary, of course, to change the wheelhouse, in addition to the mudguards. They were wider by 5.6 cm in front and eight cm behind. It all ended, causing the taillights to be replaced and about seven inches further apart. It gave a more aggressive air.


That had to be done. Because the engine in the front has almost 200 HP more than the “normal” Stingray, which is already car for no one to fault. This Chevrolet’s concern with stability led her to put a front air diffuser and side frames on the front mudguards for the wheels to be under the bow. The Z07 package includes adjustable spoilers. Apart from the air intakes in the mudguards and bonnet and the way even more wide and low, the rest looks a lot like Stingray, even if some dimensions are different.

Aluminium Frame

The chassis has been reinforced, the aluminium frame is 20% stiffer than in the old Z06. So stable, nor did it require reinforcement when creating the convertible Z06, whose weight is the same as the coupe – something very rare. The brakes were ordered from Italian maker Brembo, who designed steel discs for the “basic” version of Z06, leaving the carbon-ceramic compounds for the Z07, or for anyone who wants to pay $ 7,000 (US) for them, to have more braking force, less fatigue and 5 pounds less weight on each wheel. The American engineers were so pleased with the result that they told everyone at the car show near Las Vegas that local magazines were forced to re-calibrate their measuring instruments that showed braking numbers that seemed unrealistic, to find that the instruments were fine, The American heart that commands this beast is a 6.2 V8. Do not confuse things, this 6.2 is very different from the one used by the Camaro SS imported into Brazil. To begin with, it’s a different engine, the LT4. In addition, the new eight-cylinder unit calls for a volumetric compressor capable of rotating at 20,000 rpm to deliver maximum pressure from idle. Titanium intake valves, more resistant aluminum head, forged connecting rods, everything is adopted to increase the resistance. It is even necessary, since the 6.2 generates no less than 650 HP at 6,400 spins – the traditional Stingray delivers 466 hp. Torque? 650 also, only in foot-pounds at 3,500 rpm. Translating to units used in Brazil, the impact seems even greater. They are 629 horsepower and 89.9 kgfm of torque.


All this comes to the huge rear wheels thanks to an eight-speed automatic box that has a sequential mode, but no one really needs it, such is the efficiency of the box in understanding what the driver wants to do. But contrary to what almost every supercar maker is doing, Chevrolet has retained the option of a mechanical shift, which has seven gears and gives more control to the rider but no more speed because it is very difficult to be faster. that the computer that changes the gears in the automatic box. Still, the purists are grateful. I also, even finding it strange to have to suddenly “reduce” to sixth.

Speed and Acceleration

The numbers show the result of all this. Officially, Chevrolet says the automatic reaches 60 mph in 2.95 seconds. The top speed is 330 km / h. I have no reason to doubt. With a stopwatch in my hand and an eye to see if there was no police nearby, I managed to time 9.6 seconds from zero to 200 km / h. Not bad. Not bad. But it was not on the straight roads of the state of Nevada where the Z06 made my heart beat faster: it was on the Spring Mountains track in a town called Pahrump, an hour from Las Vegas, that it happened.


First, we walked behind one of the instructors who marked our step on the track. After three laps, faster and faster, they did the improbable and let us walk on our own. There were five or six laps I could do and I do not know if what impressed me the most was the acceleration, the ability to ride in bends or braking. The suspensions are in the style of racing cars, double triangular arms on both axles, with electronically controlled magnetic dampers. Everything happens so fast that only seeing in the replay to understand the dribbling of the Z06. Blessed technology, an on-screen system of the Corvette allows us to place an SD memory card in the glove compartment and record this turns. 


The engine uses dry sump to prevent oil from lubricating any part of the assembly after being subjected to high gravitational forces. If not, neither would the V8 resist. Just talking to colleagues and finding that they felt the same, can take away the sense of “I’m not the same” that had already invaded my head.

Generations of Corvette

There are six generations of Corvette. Generations can be referred to as version C1 to C6, but the first generation is more commonly referred to as  solid-axle  , because Independent Rear Suspension (STI) is not available until 1963. The first generation began in 1953 and ended in 1963.

First Generation (C1)

The C1 was initially equipped with a 235-cubic-inch (3,859 cm³) engine, six in-line cylinders, and two gears on the rear-wheel drive automatic transmission. It delivered 150 horsepower, reaching 170 km / h of maximum speed. The assembly was mounted under a plastic body reinforced with pressed glass fiber, which resulted in a light car. If it were not for the new material, for the first time used in automotive production and that had the commercial name of Fiberglass, the Corvette would be impracticable because of volume of production. The four-wheel drum brakes and suspension, independent at the front and rigid axle at the rear, came from other models of the brand. 

Chevrolet Corvette 1956

ZoraArkusDuntov, chief engineer of the Corvette unit since 1955, worried about the low sales figures and the model’s performance, called for changes in it. Competitors like the Ferrari 410 S and the 375 America, had V12 engines with more than 300 horsepower. At that time, Ford launched the Thunderbird,  with a 4.5-liter V8. So GM went on to work with a V8 of 265 cubic inches (4,339 cc), with 195 horsepower and reached 200 km / h. In addition, more colors were added and the optional 3-speed automatic transmission. After low sales, GM launches the Corvette in 1956 with significant stylistic changes.

Second Generation

1965: coupe with the StingRay concept

The second generation, designed by Larry Shinoda and with major inspirations in the “Q Corvette” by Peter Brock and Chuck Pohlmann, began in 1963 and ended in 1967. In 1963, the  Corvette Sting Ray (a coupe based on the concept car ” Mako Shark I “, with raised fenders, split bumpers and split rear glass. For safety reasons, the rear windows were replaced by a single one in 1964 and, because of lack of ventilation in the car due to The “327” engine of 1963 had 320 horsepower and reached 205 km / h (home tuning). In the following year, the model gained disc brakes on the 4 wheels, in addition to a new engine (6,478 cm3), of 425 horsepower and torque of 55 kgf. One of the designers’ main motives was to make StingRay compete on the tracks with the same standard as the legendary Shelby Cobra, which had a Ford V8 427 of the same power. 

1967 Corvette

In 1967, Duntov and his team launched the L88 model , equipped with the V8 427, a   7.0 liter (6,999 cm3) big-block , which used aluminum heads and three Holley double body carburetors. It is said that it actually reached 550 horsepower, but the factory declared only 430 horses to comfort the insurers. There were also changes in appearance, with a central air intake that joined the crease of the hood. Of the 28,000 Corvette  sold that year, only 20 were from that version. The model was piloted by Dick Guldstrand and Bob Bondurant at Le Mans, setting the speed record on the Mulsanne straight at 274.4 km / h (though he did not finish the race). Currently the L88 of 1967 are valued at up to $ 650,000.

Third Generation

1971 Chevrolet Corvette LT1

The third generation (from 1968 to 1982) was initially inspired by the MakoShark  II concept . The new design featured retractable headlights with two front grilles for air intake for the 428 V8 430-horsepower L88 and 300-horsepower models. Another detail was the possibility of removing the rear window and the roof in the coupe version (which lasted until 1977). In 1969 entered the new engine, the 350 V8 (5,733 cm³)  small-block , that reached the maximum power of 300 horses. In 1971, General Motors (Chevrolet) inserted the  big-block , a V4 of 454 pol³ (7.440 cm³) that produced 425 horses and equipped the version ZR2while the basic model was equipped with the 270 horsepower V8 350. Like L88, only 20 (twenty ZR2 units ) were produced  .


As of 1972, with the oil crisis and new policies regarding gaseous emissions, there was a downturn in engine power and engine capacity. The big-block was in line until 1974 with maximum power of 270 horses. The 350 V8 of 1975 had only 165 horsepower.


Once again, there were modifications of style and motorization in 1977. The Corvette showed even more angular lines, a new tilted rear and narrower front. It adopted the L82 engine of 180 horsepower, based on the traditional V8 350. Another option was the L48, with the famous carburetor Rochester Quadrajet, that raised the power for 185 horses. The car reached 197 km / h and accelerated from 0 to 96 km / h in 7.8 seconds, good marks for those difficult times.
