Will the Toyota 4Runner go four-cylinder?
Probably. Toyota will be looking for better fuel economy from the 4Runner. That will likely mean a smaller displacement engine than the 4.0-liter V6 and turbocharging and a transmission offering more than five speeds.
The favorite for the base engine is turbocharged 2.4-liter inline-four from the all-new Lexus NX 350, which puts out 275 horsepower and 317 lb-ft of torque (substantially more torque than the current V6).
Higher trim 4Runners could get an upgraded engine option to compete with the Wrangler and Bronco. But that may not be the 400 hp 3.5-liter V6 from the Tundra.
