Geo Prizm: the Toyota Corolla built by GM

The Geo Prizm was a compact car built as a rebadged Toyota Sprinter, the Japanese version of the Corolla that Toyota never sold directly in North America. It was marketed under the Geo nameplate from 1989 until 1997, then as the Chevrolet Prizm, and every one was assembled at NUMMI, the GM and Toyota joint venture in Fremont, California.

History of the Geo Prizm

First generation (E90, 1990–1992)

The Prizm was introduced in February 1989 for the 1990 model year as one of the first cars of GM’s new Geo brand of imported models. The hatchback sold through 1991 was a rebadged Toyota Sprinter Cielo, though it got the same front clip as the sedan. The sporty GSi of 1990–1992 had a 130 hp (97 kW) twin-cam engine, sport suspension, disc brakes and 14-inch wheels, and it was the only four-door model in America offered with Toyota’s 4A-GE engine. The standard engine produced 102 hp (76 kW), and the better-equipped LSi added body-coloured bumpers. In 1991 the name lettering changed, base cars got body-coloured B-pillars and door frames, and the hatchback was dropped. The Prizm was not sold in Canada, where GM offered a sedan version of the Geo Metro instead.

Second generation (E100, 1993–1997)

The second generation arrived in 1992 for the 1993 model year and was the last Prizm to wear the Geo badge. It grew into the US Environmental Protection Agency’s “compact” class, gained a driver’s airbag and offered a new 1.8-litre four-cylinder on the LSi, with a rear stabilizer bar, wider tyres and an optional four-speed automatic instead of a three-speed. A second airbag became standard for 1994, and leather seats were optional on the LSi. Unlike the Sprinter sold in Japan, this Prizm had no front stabilizer bar. US Electricar used the Prizm as the basis of an electric conversion sold in 1994.

Third generation (E110, 1998–2002)

The 1998 redesign coincided with the end of the Geo brand, so the car became the Chevrolet Prizm. Its new 1.8-litre 1ZZ-FE engine was all-aluminium, used a timing chain and powered every Corolla and Prizm of the generation. The Prizm and Corolla were the first compact cars to offer optional side airbags. Cars without the LSi handling package, which included a front stabilizer bar, were criticised by Consumer Reports for sloppy emergency handling, and Toyota made the package standard for 1999. For 2000 the engine gained variable valve timing, raising output from 120 to 125 hp (89 to 93 kW). The last Prizm was built on 13 December 2001, giving a short 2002 model year.

Design and features

• Toyota engineering: the body, engines and running gear were Toyota Sprinter and Corolla parts.
• NUMMI build: assembled in California by the same GM and Toyota joint venture that had built the Chevrolet Nova.
• GSi performance: the 1990–1992 GSi was the only four-door in America with the 4A-GE twin-cam engine.
• Side airbags: the 1998 generation was among the first compacts to offer them.
• Frugal choice: a Corolla in all but badge, sold only in the United States.

Geo Prizm versions

• Base sedan (1990–1997): the standard four-door with the 102 hp engine.
• LSi sedan: more equipment, body-coloured bumpers and from 1993 the optional 1.8-litre engine.
• GSi (1990–1992): twin-cam engine, sport suspension and disc brakes, in sedan and liftback form.
• Liftback (1990–1991): a rebadged Sprinter Cielo with the sedan’s front end.
• Chevrolet Prizm (1998–2002): the third generation after the Geo brand ended.

The Prizm was the compact of the Geo range, above the Geo Metro and alongside the Geo Tracker. More cars are in the Geo collection.
