How much horsepower does the 2021 Jeep Wrangler Rubicon 392 produce?
Answer
470 horsepower
Answer
470 horsepower
The 2021 Jeep Wrangler Rubicon 392 produces 470 horsepower.
The Rubicon 392 was the first factory-built Wrangler with a V8 engine. Its 6.4-liter HEMI V8 delivers 470 horsepower and 470 pound-feet of torque, making it substantially more powerful than the regular Wrangler engines offered at the time. The “392” name refers to the engine’s displacement in cubic inches, not its horsepower rating.
Jeep paired the V8 with an eight-speed automatic transmission and four-wheel drive. The high-output Wrangler was engineered for both straight-line performance and trail use, retaining Rubicon hardware such as locking differentials, a disconnecting front sway bar, and low-range gearing.
A frequent mistake is choosing 392 horsepower because of the model name. Another is confusing horsepower with torque: both figures are 470, but horsepower measures power output while torque measures twisting force. Jeep’s published performance claims included a 0-to-60-mph time of about 4.5 seconds.
