The Toyota 4Runner could benefit from a hybrid upgrade

Optimizing the 4Runner with some electric power could make one of Toyota’s most popular SUVs an even bigger hit. Despite its terrible gas mileage

 over 100,000 4Runners sell yearly. The 2023 model has a 270-hp V6 paired with a five-speed automatic transmission

That powertrain earns only 17 mpg combined — far below many midsize rivals

 A hybrid 4Runner could improve that estimate significantly, but it might sacrifice the V6 engine. Rumors indicate the 4Runner’s new base engine will be a turbo-four

 similar to the new Toyota Crown sedan’s powerplant. With the hybrid engine upgrade, the Crown earns 30 mpg combined.
