The practical takeaway is that horsepower is defined, but the XJ's driving feel comes from its torque delivery, which helps off-road capability and acceleration at lower speeds.
Real-world considerations
While 190 hp is the nominal figure, factors like engine wear, maintenance history, and modifications can shift actual output. Owner-maintained engines in good condition tend to track close to the published rating, whereas worn components or performance-tuning can alter both horsepower and torque bands. The Cherokee XJ's 4.0's strength lies in its mid-range torque more than high-end horsepower, making it well-suited for towing and off-road use.
