Could be one reason. For a heavy duty, used around the world off roader like the Land cruiser (unlike other expensive SUVs, this does see horrible roads and area's off questionable petrol quality and service stations being further away than a mid haul flight), surely a NA engine is preferable, at least in petrol guise. Also, these modern really down sized turbos (I look at you, small EcoBooost in my Ford or any VAG TSI) have a tendency to have very little torque above idle for the first few hundred revs (well, very small displacement having to handle a turbine as well no wonder), which also would be less favorable than the linear power delivery of a large NA engine in demanding off roading.
