How much horsepower does a 1990 Cavalier have?
Most 1990 Cavaliers delivered around 90 horsepower with the standard 2.0-liter inline-4. The sportier Z24 variant, which used a 2.8-liter V6, delivered about 140 horsepower. Exact figures can vary slightly by trim, emission certification, and drivetrain.
Engine options and horsepower in the 1990 Cavalier
The 1990 Cavalier lineup was essentially split between a standard 2.0L four-cylinder and a higher-performance option with a 2.8L V6. The horsepower values below reflect typical factory ratings from that era; some sources list different numbers due to SAE gross versus SAE net measurement and year-to-year changes.
Before listing the engines and horsepower, note that you should verify the exact figure for a specific vehicle using its option codes or VIN.
- 2.0-liter inline-4 (OHV) — typically about 90 horsepower (with minor variation by model year and emission equipment).
- 2.8-liter V6 — about 140 horsepower (sport-oriented Z24 trim), with occasional listings around 140–145 horsepower depending on production year.
In summary, the majority of standard Cavaliers from 1990 carry roughly 90 hp, while the Z24 sport variant with the 2.8L V6 offers significantly more power, around 140 hp.
Notes on trims and transmissions
Transmission choices and drivetrain can affect how horsepower translates to on-road performance. The Z24 trim typically paired with either a manual or automatic transmission depending on the year and market, while base models offered a mix of manual and automatic options. The engine and transmission pairing also influence acceleration and drivability, even when horsepower ratings are similar.
Summary
The 1990 Cavalier’s horsepower depends on the engine: about 90 hp for the standard 2.0L inline-4, and about 140 hp for the Z24’s 2.8L V6. Real-world output can vary due to wear, emissions equipment, and measurement standards.
