The Chevrolet Nova or Chevy II was an American compact car introduced by the Chevrolet division of General Motors in 1962. The original Chevy II was of unibody construction, powered by an OHV inline-four or six-cylinder engine, and available in two-door and four-door sedan configurations as well as convertible and station wagon versions. After the rear-engine Chevrolet Corvair was handily outsold by the conventional Ford Falcon in 1960, Chevrolet began work on a more conventional compact car that would eventually become the Chevy II.

Available engines for the Chevy II included a 153 in³ four-cylinder and a 194 in³ inline six. The six-cylinder was actually the third generation engine, replacing the second generation Stovebolt. Rival manufacturer Chrysler introduced the Slant Six in their Plymouth Valiant, a Chevy II competitor.

Although the Nova was not originally available with a V8 option, the engine bay was perfectly proportioned for one. It wasn't long before Chevrolet V8s were offered as dealer-installed options (between 1962 and 1963), up to and including the fuel injected version available in the Corvette. The combination of readily available V8 power and light weight made the Nova a popular choice of drag racers.

For 1963, the Chevy II Nova Super Sport was released. As mentioned above, Novas could not "officially" have V8 engines at this time — the standard SS engine was the six-cylinder — but many ended up with a small-block V8 under the hood. For 1964, the Chevy II's first factory V8 option was introduced, which was a 195 hp 283 in³ V8. In 1965, a 327 in³ V8 was also available with up to 300 hp.

In 1962 and 1963 the Nova was available in a convertible body style, and a two-door hardtop was available from 1962 to 1965.

1966 Novas saw a significant restyling, based in part on the Super Nova concept car. In general, proportions were squared up but dimensions and features changed little. Engine options still included the basic inline four and six-cylinder engines and V8s of 283 and 327 in³ (4.6 and 5.4 L), the latter offering now offering up to 350 hp.

During this time, the 90 hp 153 in³ four-cylinder engine was only offered in the base Chevy II 100 series models with the 120 hp 194 in³ inline-six standard on the Nova and Nova SS. In addition to the V8s, other optional engines included a 140 hp 230 in³ six-cylinder and a 155 hp 250 in³ six-cylinder, the latter a new offering for 1967.

An extensive restyle came in 1968, when the station wagon and two door hardtop were discontinued. This body style continued (with minor revisions) through 1974. One notable change was the front subframe assembly — as compared with Ford, Chrysler and AMC, in whose cars the entire front suspension was integrated with the bodyshell, a separate subframe housing the powertrain and front suspension (similar to the front part of the frame of GM's full-size, full-framed vehicles) replaced the earlier style. Although the front subframe design was a Chevy II-exclusive design, the Camaro introduced a year earlier was the first to incorporate such a design; the redesigned Chevy II was pushed a year back to 1968 instead of 1967. 1968 was the final year that the Chevy II nameplate was used, although all 1968 models were "Chevy II Novas" with one single trim line.

The 153 in³ four-cylinder engine was offered between 1968 and 1970, then was dropped due to lack of interest. Far more popular were the 250 in³ six-cylinder and the base 307 in³ V8, which replaced the 283 in³ V8 offered in previous years. At mid-year, a semi-automatic transmission based on the Powerglide called the Torque-Drive was introduced as a low-cost option for shiftless motoring for both the four and six-cylinder engines. The two-speed Powerglide was still the only fully-automatic transmission available with most engines as the more desirable three-speed Turbo-Hydramatic was only available with the largest V8 engines.

The SS was transformed from a trim package to a performance option for 1968 and now included a 295 hp 350 in³ V8 engine along with front disc brakes, heavy-duty suspension and other performance hardware. Optional engines included two versions of the big-block 396 in³ V8 rated at 350 and 375 hp. Both engines were offered with a choice of transmissions including the M-21 close-ratio four-speed manual, the M-22 heavy-duty "Rock Crusher" four-speed manual, or the three-speed Turbo-Hydramatic 400 for those who preferred automatic shifting.

[edit] 1969

For 1969, the Chevy II nameplate was retired and the car became the "Chevrolet Nova" for this year (some sources referred to it as the Chevrolet Chevy Nova - perhaps the decision to drop the Chevy II moniker was a last-minute decision for 1969). No Chevy nameplates remained for 1969. The trunklid badge "Chevy II by Chevrolet" was replaced by "Nova by Chevrolet" Like other 1969 GM vehicles, locking steering columns were incorporated. Simulated vents were added below the Nova script, which was relocated to the front fender instead of the rear quarter panel. The 350 in³ V8 with four-barrel carburetor that came standard with the SS option was revised with a 5 hp increase to 300 hp while a two-barrel carbureted version of the 350 in³ V8 rated at 255 hp was a new option on non-SS models. A new Turbo-Hydramatic 350 three-speed automatic was made available for non-SS Novas with six-cylinder and V8 engines.

[edit] 1970

Basically a carryover from 1969; the side markers and taillight lenses for the 1970 Nova were wider and positioned slightly differently. This was the final year for the SS396. All other engines were carried over including the seldom-ordered four-cylinder which was in its final year. The car finally became simply the Chevrolet Nova this year after two years of transitional nameplates (Chevy II Nova in 1968 and Chevrolet Chevy Nova in 1969).

Approximately 177 COPO Novas were ordered, with 175 converted by Yenko Chevrolet. The other two were sold in Canada.

[edit] 1971

1971 Novas were similar to the previous year but with the loss of the simulated fender vents and the discontinuation of the 396 in³ engine for the SS with the 350 in³ engine taking its place. 1971 also saw the introduction of the Rally Nova, a trim level that only lasted two years (until it resurfaced in 1977). The Rally kit included black or white stripes that ran the length of the car and around the back, a Rally Nova sticker on the driver's side of the hood, and Rally wheels.

The 250 in³ six-cylinder engine was now the standard Nova engine with the demise of the 153 in³ four-cylinder and 230 in³ six-cylinder engines. The 307 in³ and 350 in³ V8s were carried over from 1970 and all engines featured lowered compression ratios to enable the use of unleaded gasoline as a result of a GM corporate mandate that took effect with the 1971 model year.

After 1971, other GM divisions began rebadging the Nova as their new entry-level vehicle, such as the Pontiac Ventura II (once a trim option for full-size Pontiacs to 1970), Oldsmobile Omega and the Buick Apollo. Interestingly, the initials of the four model names spelled out the acronym NOVA (Nova, Omega, Ventura, Apollo).

[edit] 1972

A virtual rerun of 1971, the 1972 Nova received only minor trim changes and both the Rally Nova and SS options were carried over. At mid-year a sunroof option became available on two-door models. Also, the optional Strato bucket seats available on coupes switched from the previous low-back design with adjustable headrests to the high back units with built-in headrests introduced the previous year on Camaros and Vegas.

[edit] 1973-1974

The 1973 model year introduced a hatchback bodystyle based on the 2-door coupe. Following a government mandate for vehicles to be fitted with front and rear bumpers capable of absorbing a low-speed impact of 5 mph, the front and rear of the Nova were restyled. A modified rear side window shape was also introduced and a revised rear suspension adapted from the second generation Camaro with multi-leaf springs replacing the mono-leaf springs used on Novas since the original 1962 model. By this time, six-cylinder and V8 engines were de rigeur for American compact cars, with the 307 in³ and 350 in³ (5.0 and 5.7 L) V8s becoming fairly common. Nova SS models offered a higher-performance 350 in³ V8. The 1973 Nova with a six-cylinder engine or 307 in³ V8 were among the last Chevrolets to be offered with the now-outdated two-speed Powerglide automatic transmission, which was in its final year. For 1974, it was replaced by a lightweight version of the three-speed Turbo-Hydramatic 350 already offered with the 350 in³ V8, which was the only V8 offered for 1974. These Novas where also fitted with a weight sensitive relay within the front bench seat that prevented the vehicle from being started until the driver's seatbelt had been fastened. Later, a law passed by Congress banned this type of device, declaring that it infringed on a driver's freedom of choice. [1] The devices were not included in future Nova models.

A luxury-themed Nova Custom became part of the model lineup which included upgraded upholstery, full carpeting and more exterior trim. The SS option was still available but became more of a sporty trim package than a performance offering and now offered with any Nova engine, much like the 1963 to 1967 Nova SS.

Buick and Oldsmobile entered the compact car market; both the Apollo and Omega debuted, using the same bodystyles from the Nova lineup. Additional options were included on these Nova-like models, such as lighting under the dashboard and in the glove compartment. Pontiac's final GTO of this era was based on a facelifted 1974 Ventura coupe fitted with a shaker hoodscoop from the Trans Am.

A completely restyled Nova was introduced in 1975 and continued through 1979. Base coupes, including the hatchback, had fixed side windows (or optional flip-out windows) and vertical vents on the B-pillar.

Six-cylinder and V8 engines remained the norm through the end of the decade (and the end of the rear-wheel drive X platform).

The front suspension and subframe assembly was similar to the one used in the second generation GM F-body cars (the Camaro and Pontiac Firebird), whereas the rear axle and suspension were carried over from the previous generation.

The Nova lineup ranged from the stripped-down "S" model, base, Custom (1975 and 1978 to 1979, which in later years became the LN and Nova Concours replacement), and the luxury-themed LN (the LN was the first to sport metric displacement badges — either "4.3 LITRE" or "5.7 LITRE"). The LN was replaced with the Nova Concours (1976 and 1977; 1977 models had a 3-taillight lens scheme much similar to the Impala with a Cadillac-esque front clip). All were intended as competition for the recently introduced Dodge Aspen/Plymouth Volare and Ford Granada/Mercury Monarch. From 1977 to 1978, there was also the Nova Rally (not to be confused with the Rally Nova of the early 1970s). These came with the 305 in³ V8 engine, and some with the 4-speed Saginaw manual transmission.

The Apollo was replaced by the sportier Buick Skylark after 1975 (during the 1975 model year, the Apollo nameplate was used for the 4-door sedan, while the coupe was badged as the Skylark), while Pontiac's Ventura became the more luxurious Phoenix for 1978 (the Phoenix was the first X-body fitted with square headlights). Rebadged versions of the Nova had either a Chevrolet inline-six or Buick V6 as the base engine.

During the 1977 model year for the Ventura, the GM Iron Duke was the base engine (in response to the Arab Oil Embargo) coupled to a Borg-Warner T-50 transmission (it has no relationship to the T-5 found in third-generation GM F-bodies). The Ventura was replaced by the Phoenix in the middle of the 1977 model year.

Base V8 engines included Chevrolet 262 in³ and 305 in³ engines, and an Oldsmobile 260 in³ V8; Pontiac Venturas were not fitted with a Pontiac V8 from the factory after 1975, when Oldsmobile 260s and Buick 350s were installed as optional equipment. This led to civil action against GM.

The Nova SS continued for 1975 and 1976; when the SS was discontinued, the option code for the SS — RPO Z26 — continued as the Nova Rally until 1979.

Even Cadillac got into the act; the Nova's X platform was stretched by several inches and fitted with an Oldsmobile fuel-injected V8 to become the Seville for 1975.

A high-performance police version of the Nova was introduced for the 1975 model year, making it the first compact car certified for police duty in the US. Most were initially purchased by the Los Angeles County Sheriff's Department in 1976.

The Nova's final model year, 1979, saw few changes. The front end was revised with square headlights and a new grille for the short run. Production ended on December 22, 1978.

From 1980 onwards, the Nova's original niche in the Chevrolet lineup was filled by front-wheel drive compacts including the Citation (1980 to 1985), and Corsica (1987 to 1996). Upon introduction of the downsized GM A-body (later G-body) mid-size cars in 1978, the X-body and downsized A-platform had similar dimensions, and the more modern downsized A-bodies outsold their X-body counterparts.

In 1985, the Nova name was applied to a rebadged Toyota Sprinter, an upmarket version of the Toyota Corolla that replaced the Citation and was produced at the NUMMI plant in Fremont, California, as an historic first joint venture between General Motors and Toyota. 1988 was the last year for the Nova nameplate on any platform; its replacement arrived in Geo-Chevrolet showrooms as the Geo Prizm the following year.

[edit] Novas abroad

[edit] Argentina

The early third generation (1968 model) Nova was marketed in Argentina as the Chevrolet Chevy from late 1969 through 1978. The first and second generation Novas were sold as the Chevrolet 400; the second generation Nova was produced until 1974.

Their SS counterparts were both coupes and 4-door sedans, the latter of which was unheard of in the US prior to the introduction of the 1994 Impala SS. In fact, a majority were fitted with inline-sixes coupled to a ZF manual transmission.

[edit] Novas in popular culture

[edit] The urban legend

A popular urban legend asserts that the Nova sold poorly in Latin America because the phrase no va means "does not go" in Spanish. In reality, the Spanish no va and nova are as different as the English no table and notable. [2] The word nova exists in Spanish with the same meaning as in English. Also, the Spanish word for 'new' (nuevo or nueva) is cognate to nova, which originally meant "new" in Latin. Finally, as NOVA was a brand of gasoline sold for many years by PEMEX in Mexico, the largest of all Spanish-speaking Latin American countries, it is clear that this urban legend, while perhaps entertaining, is utterly baseless.
