![]() ![]() Naturally, full throttle fires up the engine, but gentler driving can too. We found the gas engine-which isn't fully defeatable in any of the three drivetrain modes-always eager to take over. We also were unable to replenish noticeable EV range while in Hybrid mode, but were able to recharge some of the battery while driving in eSave, a mode that uses power from the gas engine only. ![]() Flatten the accelerator and there's a pronounced delay before any actual movement. In the vastly more polished Grand Cherokee, the powertrain's hesitation and its abrupt transitions stand out. In the Wrangler, we noted this powertrain's rocky transitions between gas and electric propulsion, although they were somewhat lost amid the Wrangler's general cacophony and numb, vague chassis.

The combined output is 375 horsepower with 470 lb-ft of torque. ![]() A 270-hp turbocharged 2.0-liter inline-four engine with 295 pound-feet of torque is assisted by a belt-driven 44-hp motor and another 134-hp electric motor that replaces the eight-speed automatic transmission's torque converter. The Grand Cherokee 4xe, which is exclusive to the two-row version, uses the same plug-in-hybrid powertrain as the Wrangler. ![]() For Grand Cherokee buyers, however, the decision to step up to the plug-in hybrid is not so obvious. Given that reception, applying the 4xe treatment to the brand's bestseller, the Grand Cherokee, must have seemed like a no-brainer. That would mean it beat out PHEVs including the Toyota RAV4 Prime (27,000 units) and Prius Prime (25,000), and that better than 13 percent of the more than 204,000 Wranglers sold last year were PHEVs.
