2021 Jeep Wrangler 4xe pricing confirmed for hybrid SUV Chris Davies - Dec 23, 2020, 9:24am CST Pricing for the new Jeep hybrids has been confirmed, with the 2021 Jeep Wrangler Sahara 4xe and Jeep Wrangler Rubicon 4xe Launch Editions slotting in at the top end of the SUV-maker’s range. Announced earlier this year, the first electrified Wrangler models combine a four-cylinder gas engine with two electric motors, for what the automaker claims is a bump both in economy and performance. The gas engine is a 2.0-liter turbocharged inline-four, with a low-inertia turbo and direct-injection. Mounted to it is a high-voltage eTorque motor generator unit, in place of the standard alternator. It’s also used to help charge the 400-volt, 17 kWh lithium-ion battery pack.
