Jeep Wrangler eTorque Mild Hybrid Technology

The 2019 and 2020 Jeep Wrangler sports two engine options featuring their new eTorque Mild Hybrid Technology, which offers better fuel economy and improved towing capacity.

What is Jeep Wrangler's eTorque Mild Hybrid Technology?

New 2019 and 2020 Jeep Wrangler has an innovative eTorque Mild Hybrid system that has improved fuel economy without sacrificing power, torque, or capability. It requires no additional effort by the driver and is part of both the 3.6L Pentastar V6 engine and the Turbocharged 2.0L I4 engine.

The new Jeep eTorque mild hybrid system is a replacement for the traditional alternator. It sports a belt-driven motor generator unit that executes several different functions.

How Does Jeep Wrangler's eTorque Mild Hybrid Technology Work?

A 48-volt battery pack works with the motor generator to create:

  • a seamless start/stop function;
  • a short-duration torque addition to the engine crankshaft in particular driving conditions; and,
  • brake energy regeneration to increase efficiency and responsiveness.

When the engine is running, eTorque's motor generator unit delivers 48-volt current to a 430 watt-hour lithium-ion Nickel Manganese Cobalt (NMC)-Graphite battery. The battery pack includes a 3-kilowatt DC-to-DC converter. This holds the battery's charge and converts 48 volts to 12 volts so that power can be use to power Jeep Wrangler's accessories and charge its conventional 12-volt lead-acid battery.

About the size of a small suitcase, the air-cooled battery pack is mounted to the interior rear wall of Jeep Wrangler's cabin. The battery pack's case is insulated to hush the noise generate by the dual cooling fans. Cooling air is then drawn from the vehicle interior and released through the built-in cabin exhausters.

Because of its greater efficiency in extreme temperatures, both the 3.6L Pentastar V6 engine and the Turbocharged 2.0L I4 engine with Jeep eTorque technology will keep a traditional 12-volt starter motor, which is ideal for cold starts and the initial start of the day.

Beyond spinning the engine for restarts, the Jeep eTorque also recaptures energy during deceleration and braking to recharge the battery pack. Further, eTorque also bolsters the driving experience of the 2019 and 2020 Jeep Wrangler with additional torque to the crankshaft during gear changes, which minimizes noise, vibration, and harshness (NVH).

Both engines sport a liquid-cooled Jeep eTorque unit mounted on the front of the engine, which uses a pair of belt tensioners to ensure that the 8-rib drive belt stays tight when the unit is generating electricity or adding torque to the crankshaft.

With the eTorque Mild Hybrid system, the 3.6L Pentastar V6 engine boasts 285 horsepower and 260 pound-feet of torque. Maximum torque arrives later in the rev range, at 4,800 rpm. The Turbocharged 2.0L I4 engine generates best-in-class 270 horsepower, 295 pound-feet of torque.

Jeep Wrangler's eTorque Mild Hybrid Technology Warranty Information

The 2019 and 2020 Jeep Wrangler comes backed by a 5-year/60,000-mile Powertrain Limited Warranty, which covers the cost of all parts and labor needed for repairing a covered powertrain component – engine, transmission and drive system.

In addition, as part of the Basic Limited Warranty, the Federal Emission Warranty covers the following parts of the Jeep eTorque system for 7 years/70,000 miles, whichever comes first.

  • EGR Cooler — 2.0L and 3.6L engines
  • Fuel Tank Assembly — 2.0L and 3.6L engines
  • Transmission Control Module — 2.0L and 3.6L engines
  • Turbocharger — 2.0L engine

Further, as part of the Basic Limited Warranty, the Federal Emission Warranty covers the following parts of the Jeep eTorque system for eight years/80,000 miles, whichever comes first.

  • Belt Driven Hybrid Starter Generator — 2.0L and 3.6L engines with BSG (If Equipped)
  • Catalytic Converter — 2.0L and 3.6L engines
  • Powertrain Control Module — 2.0L and 3.6L engines
  • Power Pack Unit — 48 Volts 2.0L and 3.6L engines with BSG (If Equipped)

The "Warranty Coverage at A Glance" graph in the 2019 and 2020 Wrangler Standard Factory Warranty Booklet provides an overview perspective of the above described eTorque warranties on the Wrangler from 1 year/12,000 miles through 8 years/80,000 miles.
