Subaru will bring no fewer than three concept cars to the Tokyo motor show in a matter of weeks, and the automaker has just released images previewing a concept sports sedan, which will likely foreshadow the next-generation WRX. Dubbed the Subaru Viziv Performance Concept, the sedan evidently features relatively wide wheelarches and large vents compared to the greenhouse, suggesting not only the presence of some wide wheels and tires but serious brake ventilation.

Up front the concept wears the now-familiar hexagonal grille in addition to L-shaped headlights flowing to the grille itself, while the rear fascia appears to feature a relatively short trunk with an integrated spoiler. Notably absent are traditional side mirrors — likely just cameras on small pylons feeding the image to A-pillar-mounted screens — while a view of the front reveals sensors mounted at the leading edge of the roof. Subaru promises this concept will feature advanced driver assist technology, so these sensors could be part of an upgraded EyeSight driver assist system.

Another item of note are fins mounted at the top of each wheelarch that appear to house small lights. The size of the fins themselves suggests something more than simple blind-spot detection systems, and may be related to some level of autonomous driving technology.

“The model expresses the enjoyment of driving by adopting a sports sedan style based on Subaru’s shared design philosophy of “DYNAMIC x SOLID”, while realizing its future vision for safety with advanced driver-assist technology, centered on Subaru’s original EyeSight driver-assist system,” the automaker said in an opaque statement announcing the concept sedan. “Subaru will also premier new retail models, and exhibit the models that will race in the Super GT series.”

The concept will feature some pretty serious wheelarches, ones with likely vents for brakes.

Even though the Viziv concept appears to preview the next-gen WRX, the car itself isn’t due until 2020, by which time the driver-assist tech previewed here will likely be production-ready. It remains to be seen just what kind of autonomy a production version of this sedan will offer and what kind of sensors Subaru will add to its EyeSight system.

We’ll see this concept in the metal along with a special edition WRX STI model called the S208, just 450 of which will be built, and a special edition of the BRZ STI Sport that will be limited to 100 cars. These special editions, it appears, are meant solely for the Japanese domestic market, but Subaru will have plenty of other things for a worldwide audience to see in Tokyo, and we’ll have them all for you here as we get more details.
