The 2006 Jeep Commander with the 5.7-liter Hemi makes 345 horsepower and 375 lb-ft of torque.
In this report, we examine what those figures mean for daily driving, towing capability, and how the engine fits into the Commander’s 2006 lineup.
Engine specs and context
The 5.7 L Hemi used in the Commander is rated at 345 horsepower (SAE net) and 375 lb-ft of torque. Peak horsepower typically arrives around 5,200 rpm, while peak torque sits near 4,000 rpm. The engine uses Chrysler’s multi-displacement technology and variable valve timing in this generation, and it was paired with a five-speed automatic transmission and optional four-wheel drive.
What those numbers mean in practice
Horsepower and torque together describe the engine’s ability to accelerate and tow. The 345 hp rating signals strong highway and merging power for a mid-size SUV of its era, while 375 lb-ft of torque provides useful pulling power at lower revs, improving launch feel and mid-range acceleration.
Context in the 2006 lineup
Across the 2006 Commander lineup, the 5.7 Hemi was the top-tier engine option, available with rear-wheel drive or all-wheel drive. The 4x4 setup offered additional off-road capability and traction, while the automatic transmission delivered smooth shifts suitable for daily driving and towing duties. Fuel economy varied with drivetrain, payload, and terrain, but the horsepower figure remained 345 hp for that model year.
Reality check: performance and expectations
Power numbers summarize engine capability, not a guaranteed sprint. For a vehicle of its size, the 345 hp 5.7 Hemi provides strong takeoff and solid passing power, especially when paired with the Commander’s weight and gearing. Reviews from the era commonly noted adequate power for daily use and respectable highway performance for a mid-size SUV with towing potential.
Summary
The 2006 Jeep Commander with the 5.7-liter Hemi is rated at 345 horsepower and 375 lb-ft of torque, with peak horsepower around 5,200 rpm and peak torque around 4,000 rpm. This combination offered robust mid-range torque and confident highway performance for its class and era. Real-world results depend on drivetrain configuration and payload.
