The Geo Prizm and Chevrolet Prizm were compact cars that were rebadged versions of the Toyota Sprinter, a vehicle that the Japanese automaker Toyota never directly sold in the North American market. The Sprinter itself was derived from the Toyota Corolla. The Prizm was marketed under the Geo nameplate until it was discontinued after the 1997 model year. After that, the vehicle was marketed under the Chevrolet nameplate. General Motors (GM) referred to this and other Toyota Corolla derived vehicles as the GM S platform. The cars were produced from 1988 to 2002 alongside the Corolla at NUMMI, an assembly plant operated as a joint venture of GM and Toyota. The Prizm was sold exclusively in the United States and succeeded the 1985–1988 Chevrolet Nova, which was also derived from the Sprinter and produced at NUMMI.

Production

All Prizms were built at NUMMI (New United Motor Manufacturing, Inc.), a joint venture company between Toyota and General Motors in Fremont, California. The NUMMI plant at Fremont had manufactured the Prizm's predecessor, the Chevrolet Nova, and would later manufacture the Pontiac Vibe, one of its replacements. The last Prizm was built on December 13, 2001, resulting in a brief 2002 model year.

The Prizm was introduced in February 1989 for GM's then-new Geo brand of import cars, for the 1990 model year. [1] The hatchback version sold through 1991 was a rebadged version of the Toyota Sprinter Cielo, although unlike the Sprinter (and Corolla liftback) it received the same front clip as the sedan. The sporty GSi model of 1990–1992 was notable for its 130 hp (97 kW) twin-cam engine, sport suspension, disc brakes, and 14-inch wheels, a successor to the 1988 Nova twin-cam but less of a limited edition, available in both body styles and a full array of colors in contrast to the earlier model's black sedan only. They were the only four-door models offered with the 4A-GE engine in America, no Toyota model ever offered that combination. The regular engine offered 102 hp (76 kW). [1] In addition to the base and the GSi, there was also a better equipped standard-engine LSi model. In addition to more equipment, the LSi also received body colored bumpers.

In 1991, the lettering of the car's name was changed to "PRIZM" in italicized and capital letters (although the steering wheel continued to use Prizm), and the B-pillar and door frames on base models were body-colored instead of black. The Prizm was not sold In Canada, with GM offering a sedan version of the Geo Metro instead. The Geo Metro sedan was not available from Chevrolet dealers in the United States until 1995, although a Suzuki Swift-branded version was on sale from 1990. Design patents were filed by the Toyota Motor Corporation on December 6, 1985, using a final design 1:1 representation, under application number 1985-051078 and registered on July 13, 1988, under registration number 0718088-005.

The Prizm's second generation, and the last under the Geo brand name, debuted in 1992. The Prizm gained more room (resulting in an upgrade to United States Environmental Protection Agency "compact" car status), a driver's-side airbag, and a new 1.8-liter four-cylinder engine optional on LSi trim. With the larger engine came a rear stabilizer bar, wider tires, and an optional automatic transmission with four speeds instead of three. A second airbag became standard in 1993; leather seats were an option on the LSi of this generation. In contrast with the Sprinters sold in Japan, this generation Prizm lacked a front stabilizer bar in its suspension.

The Prizm's 1998 redesign coincided with the conversion of all remaining Geo models into Chevrolets, as General Motors made the decision to discontinue the Geo brand entirely after 1997. The most notable change was the new 1.8-liter engine, which was now all-aluminum, driven by a timing chain (instead of a belt), and making more power (with the same fuel economy) than the engines from the Geo years. The new all-aluminum 1ZZ-FE engine powered all Corollas, Sprinters, and Prizms, making this generation lighter than its predecessor. This new engine incorporated laser-etched valve guides directly in the block, rather than the old shrink to fit valve guides in the previous Corolla motor (4A-FE & 7A-FE). This prevented oil burning and valve guide failure.

The Prizm, alongside the Corolla, became the first car in the compact class to offer optional side airbags. All 1998 Prizms without the LSi's optional handling package (containing a front stabilizer bar) were singled out by Consumer Reports for having sloppy emergency handling; Toyota addressed the problem for 1999 by making the handling package standard. For 2000, the engine gained variable valve timing for five extra horsepower (to 125).

Due to decreased sales, low popularity, and being in competition with the Chevrolet Cavalier and GM's more direct competitor to the Corolla the Saturn S-series, the Prizm was replaced by the Pontiac Vibe starting in 2003. The Vibe was also made in tandem with a Toyota model, the Toyota Matrix, at the NUMMI plant.

The Prizm along with its Geo siblings suffered severe sales loss when the brand denomination changed from Geo to Chevrolet in 1998. The Geo models outsold the rebadged Chevrolets three to one.

Comparison to Toyota Corolla

In any of its three generations, the Prizm was virtually the same car as the Toyota Corolla. It has more similarities with Toyotas of the time period it was produced than it does to other cars from Geo and Chevrolet. Its distinctions mostly came down to minor cosmetic differences, a GM Delco radio after 1992, and the non-availability of a wagon in all three generations, and the availability of a hatchback for the 1989-1992 model years (the Corolla was not offered as a hatchback in North America for those years). The third generation Prizm also featured a Delphi air conditioning system instead of the Corolla's Denso air conditioning system. All Prizms also used the contemporary Sprinter front end to differentiate them from their Corolla counterparts.

Engines

All Prizms are powered by engines from their contemporary Toyota Corolla models:

Pontiac Vibe Motor vehicle

The Pontiac Vibe is a compact car that was sold by Pontiac from 2002 to 2010. It was jointly developed by General Motors along with Toyota, who manufactures the mechanically similar Toyota Matrix. Manufactured by the Toyota-GM joint venture NUMMI in Fremont, California, the Vibe succeeded the Chevrolet Prizm in production at NUMMI and like the Prizm, it was derived from the Toyota Corolla, making it the last of the GM and Toyota developed S-body cars.

Geo was a marque of small cars and SUVs marketed by General Motors as a subdivision of its Chevrolet division from 1989 to 1997. Formed by GM to compete with the growing small import market of the mid 1980s, the Geo nameplate continued through the 1997 model year when the brand merged with Chevrolet brand itself, after which the remaining models were marketed under the Chevrolet name; for the 1998 model year, the Metro, Prizm, and Tracker were sold as Chevrolet until their discontinuance in 2001, 2002, and 2004, respectively. In this sense, Geo existed until 2004, even with the Geo nameplate being dropped in mid-1997. Its original slogan was "Get to know Geo" and commercials often featured the song "Getting to Know You" from the musical The King and I. In the 1990s consumer interest in the economy compact market faded, and the last vehicle of the former Geo line, the Tracker, was discontinued in 2016. In Canada, another import marque, Asüna, was introduced in 1992 to provide Pontiac-Buick-GMC dealers access to a similar range of import vehicles.

Chevrolet Cavalier Motor vehicle

The Chevrolet Cavalier is a line of small cars produced for the model years 1982 through 2005 by Chevrolet, and then later reintroduced in 2016 for the Chinese Market. As a rebadged variant of General Motors' J-cars, the Cavalier was manufactured alongside the Cadillac Cimarron, Buick Skyhawk, Oldsmobile Firenza, and Pontiac J2000/2000/Sunbird at GM's South Gate Assembly and Janesville Assembly plants, achieving its highest sales in 1984.

Rebadging Changing badges of the same car

Rebadging in the automotive industry is a form of market segmentation used by automobile manufacturers around the world. To allow for product differentiation without designing or engineering a new model or brand, a manufacturer creates a distinct automobile by applying a new badge or trademark to an existing product line.

Toyota Corolla Motor vehicle

The Toyota Corolla is a line of subcompact and compact cars manufactured and marketed globally by Toyota. Introduced in 1966, the Corolla was the best-selling car worldwide by 1974 and has been one of the best-selling cars in the world since then. In 1997, the Corolla became the best selling nameplate in the world, surpassing the Volkswagen Beetle. Toyota reached the milestone of 44 million Corollas sold over twelve generations in 2016. The series has undergone several major redesigns.

Geo Metro Motor vehicle

The Geo Metro was a marketing and manufacturing variation of the Suzuki Cultus available in North America from 1989 through 2001 as a joint effort of General Motors (GM) and Suzuki. In the US, the Metro carried a Geo nameplate from 1989 through 1997, and a Chevrolet nameplate from 1998 to 2001. It evolved with the Cultus and its siblings over 13 years, three generations and four body styles: three-door hatchback, four-door sedan, five-door hatchback and two-door convertible—and was ultimately replaced in the General Motors lineup by a family of vehicles based on the Daewoo Kalos.

Chevrolet Chevy II / Nova Motor vehicle

The Chevrolet Chevy II/Nova is a small automobile manufactured by Chevrolet, and produced in five generations for the 1962 through 1979, and 1985 through 1988 model years. Nova was the top model in the Chevy II lineup through 1968. The Chevy II nameplate was dropped after 1968, with Nova becoming the nameplate for all of the 1969 through 1979 models. Built on the X-body platform, the Nova was replaced by the 1980 Chevrolet Citation introduced in the spring of 1979. The Nova nameplate returned in 1985, produced through 1988 as a S-car based, NUMMI manufactured, subcompact based on the front wheel drive, Japan home-based Toyota Sprinter.

Toyota Sprinter Motor vehicle

The Toyota Sprinter is a compact car manufactured by Toyota as a variant of the Toyota Corolla. Exclusively sold in the Japanese domestic market, the Sprinter was aimed to be sportier than its Corolla sibling, with the Sprinter being sold at the Toyota Auto Store while the Corolla was sold at the eponymous Toyota Corolla Store, which focused on economical cars compared to the more upmarket Vista store.

Suzuki Cultus Supermini car

The Suzuki Cultus is a supermini car produced by the Japanese manufacturer Suzuki from 1983 to 2003. The nameplate is currently used as a rebadged Suzuki Celerio in Pakistan since 2017. It was first presented at the 25th Tokyo Motor Show, formally introduced to Japan in 1983 and ultimately sold in seven countries across three generations and marketed worldwide as the Suzuki Swift for the first two generations. An alliance formed in 1981 between GM and Suzuki allowed GM to market the Cultus as a captive import internationally under more than a dozen nameplates including the Geo Metro, Chevrolet Sprint, Pontiac Firefly and Holden Barina. It was also known as the M-car within GM.

Toyota Tercel Motor vehicle

The Toyota Tercel is a subcompact car manufactured by Toyota from 1978 to 1999 across five generations, in five body configurations sized between the Corolla and the Starlet. Manufactured at the Takaoka plant in Toyota City, Japan, and sharing its platform with the Cynos and the Starlet, the Tercel was marketed variously as the Toyota Corolla II — sold at Toyota Japanese dealerships called Toyota Corolla Stores — and was replaced by the Platz in 1999. It was also known as the Toyota Corsa and sold at Toyopet Store locations. Starting with the second generation, the Tercel dealership network was changed to Vista Store, as its badge engineered sibling, the Corolla II, was exclusive to Corolla Store locations.
