The Wrangler 4Xe can drive on battery power alone for up to 21 miles. The Discovery must run its internal combustion engine to move.
An engine control system that can shut down some of the engine’s cylinders helps improve the Wrangler Rubicon 392’s fuel efficiency. The Discovery doesn’t offer a system that can shut down part of the engine.
Regenerative brakes improve the Wrangler 2.0 Turbo/3.6 eTorque/4Xe’s fuel efficiency by converting inertia back into energy instead of wasting it. The Discovery doesn’t offer a regenerative braking system.
Both the Wrangler and the Discovery have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stop lights and heavy traffic. All Wranglers have a standard disable switch for the system, so a driver can keep the engine from shutting off when the vehicle stops temporarily. The Discovery P360 doesn’t offer a way to disable start/stop.
