The current-generation Toyota Fortuner will be turning four years old this year. Surprised?

Since 2016, Toyota hasn't given the popular SUV any cosmetic changes, but that's about to change soon. The facelifted Fortuner was spied in Thailand recently, and that's a big deal. With most of its rivals refreshed within the last two years, Toyota has to step it up again.

You won't see the differences since the car is wrapped in camouflage. Given the way they covered the car, there might be significant hidden underneath. They even went as far as covering the wheels, which could suggest new wheel designs.

But what can we expect? If we were to take look at how Toyota facelifted the previous-generation Fortuner, we might get a general idea of what they will do to this model. It is likely that the headlights will be redesigned for this more, and the grill might be tweaked as well. The same could apply for the bumper as well.

We're not expecting any of the metal panels to be changed for this minor model change. We reckon the fenders, doors, tailgate, and quarter panels will be carried over from the current look. What could be (slightly) altered are the rear bumper and the taillights, which is how they did it for the first-generation Fortuner.

Only the exterior was spied but updates and upgrades to the interior are to be expected. There could be new trims, color combinations, or even new graphics for the vehicle's information display. Also, the infotainment system might be changed as well, although that will depend on the specification ordered by a certain market.

The engine might be carried over as well. That means the 2.4-liter and 2.8-liter turbodiesel engines will more than likely soldier on for several more years. Remember, Toyota's 2.5-liter and 3.0-liter D-4D turbodiesels lasted for more than a decade and the new-generation D-4D mills are expected to hang around just as long, maybe even longer.

If it carries over totally unchanged, we're looking at 150 PS and 400 Nm of torque from the 2.4-liter while the 2.8-liter would still make 177 PS and 450 Nm of torque. Transmission options are also likely to remain the same meaning it's either a six-speed manual or a six-speed automatic. No word yet if Toyota will continue putting in the 2.7-liter gas option for the Fortuner, but it's possible that they will still offer it.

So when will it be fully revealed? It's difficult to tell for now but a mid-year debut seems the likeliest, with the local launch possible towards the end of 2020.
