Toyota has decided to replace the outgoing 3.5-liter V6 gasoline engine with a 2.4-liter turbocharged four-cylinder engine for the 2023 Highlander, so there will be no V6 engine option.
The 265 hp and 310 lb-ft of torque generated by the turbocharged 2.4-liter inline-four engine is a 17% improvement over the torque output of the previous generation V6.
Compared to the V6, the new engine’s power output is lower, but it generates more torque and uses less gas.
The hybrid version of the 2023 Highlander is powered by a 2.5-liter DOHC four-cylinder engine paired with two electric motor-generators and a variable cooling system, and it is available alongside the new turbocharged I4 engine.
With its hybrid powertrain, this model achieves an impressive 36 miles per gallon on the highway while still providing 175 horsepower and 175 lb-ft of torque.
The hybrid’s optional all-wheel-drive system uses a motor mounted to the vehicle’s back to provide additional thrust to the back wheels when required.
The 2023 Toyota Highlander is powered by a turbocharged 2.4-liter I4 engine and offers a hybrid drivetrain as an option, but there is no V6 option.
The hybrid model achieves an impressive 36 mpg, while the turbocharged engine improves fuel economy and boosts torque.
There is no difference in the Highlander’s dependability or efficiency between the two engines.
