Despite the heavy black and white disguise concealing the front grille and bumper, we can see the facelifted crossover should get revised treatments at the front and rear.
Meanwhile, the large sensor at the centre of the lower intake suggests the new model will get radar-based technology like autonomous-emergency braking (AEB) and adaptive cruise control.

Compared to the vehicle spied in March, this latest prototype is sporting darker tail-light clusters and new camouflage on the tailgate - suggesting there will be design changes at the rear too, possibly in the form of LED rear lighting.
Further details are yet to be uncovered, though it's expected the updated Vitara will get revisions to its interior, and possibly revised engines.
Currently, the Vitara has three powertrain options in Australia - an 86kW/156Nm 1.6-litre aspirated petrol, a 103kW/220Nm 1.4-litre turbo petrol, and an 86kW/320Nm 1.6-litre turbo-diesel.
Timing is unknown at this stage, though it's rumoured the facelifted SUV will make its debut at the Tokyo motor show in October.
