The Aspen gave buyers a choice between a practical entry engine and a more powerful upgrade to boost performance and towing capacity.
- 4.7-liter Magnum V8 — Approximately 235 horsepower with about 295 lb-ft of torque. This engine was the standard option and shared components with other Chrysler SUV architectures of the era.
- 5.7-liter Hemi V8 — Around 335–345 horsepower and roughly 370–375 lb-ft of torque. This was the optional upgrade, known for stronger acceleration and towing capability.
