Sometimes a notable story slips quietly through the cycle around the holidays. Heading into the holidays, Jeep dropped the 5.7-liter Hemi V8 option from his 2023 two-row Grand Cherokee, but didn’t make a big announcement or press release.
motor authority I contacted Jeep and was told only that the Hemi V8 is no longer available in a 2 row configuration. It’s no surprise Jeep cut his V8 option after the release of the new Hurricane V6, but the only engine available in the two-row Grand Cherokee is the 3.6-liter Pentastar V6. It’s not a bad powerplant, but it lacks the power and torque of the new Hurricane Inline 6.
A new engine is exciting, but the reality is that tighter regulations and a focus on fuel economy may have played a big role in this decision. Cutting V8 that put out 14/22/17 mpg in city/highway/combined and leaving Pentastar that put out 18/25/21 mpg in 4×4 average gas mileage while Jeep figures out help improve the electrification.
This shift created the flagship powertrain for the Grand Cherokee 4xe Jeep two-row model. It offers 375 horsepower and 470 lb-ft of torque, boosting the output of the outgoing V8 by both accounts and comes standard with four-wheel drive. The Jeep is all-electric and he has a 25-mile range and a maximum of 56 MPGe for an SUV, making him one of the most efficient vehicles in its class.
Jeep never completely removed the Hemi from its catalog. Some Grand Cherokee L 3-row models and Wagoneer will continue to be equipped with the 5.7L engine. The Grand Wagoneer is powered by his 6.4-liter engine that produces 471 horsepower and 455 lb-ft of torque. If Jeep offers it in a standard Grand Cherokee two-row, the new Hurricane Twin-Turbo V6 could replace the power of the outgoing Hemi V8 without issue. It makes a maximum of 510 horsepower and 500 lb-ft of torque. Much better than Hemi’s 357 ponies and 390 pounds of torque.
