A 3.2-liter V-6 rated at 271 horsepower and mated to a nine-speed automatic provides the impetus to move this densely packed machine (it weighed 4332 pounds on our scales).There’s sufficient punch to pass two of our favorite crossovers—the Honda CR-V and the Mazda CX-5—but the Cherokee’s 7.5-second zero-to-60-mph time, its 15.8-second quarter-mile performance, and its top-gear acceleration figures all trail the Ford Escape powered by an EcoBoost 2.0-liter four-cylinder.
