The Subaru Levorg STI Sport is essentially a wagon version of the Subaru WRX STI sedan. Unfortunately, it's only sold in Japan, which makes it one of many performance wagons that are forbidden fruit here in the US. And just to make us even more jealous, there's an all-new version coming.

At the 2020 Tokyo Auto Salon, Subaru presented a new prototype previewing the new next-generation Levorg STI Sport wagon. Subaru says the all-new Levorg STI is being developed with the aim of "realizing a future where everyone can truly enjoy driving in a car that enriches the life of the customer."

Details are scarce, but the all-new Levorg Prototype STI Sport is the first Subaru model to feature electronically controlled dampers that improve the ride quality and provide sportier driving dynamics.

For the first time in a Subaru model, the high-performance wagon prototype also features a "Drive Mode Select" system that allows the driver to adjust the driving characteristics at the push of a button such as settings for the engine, steering, dampers, and the all-wheel-drive system. Expect the production version to ride on the new Subaru Global Platform that underpins the new Subaru Outback wagon.

Compared to the Levorg Prototype that debuted at the 2019 Tokyo Motor Show, the hot STI version features the usual upgrades we've come to expect from the performance division, including sportier styling, unique wheels and STI badging. Sadly, the windows are blacked out, preventing us from getting a peek inside the cabin.

Powertrain details of the prototype were not released by Subaru, but the current Levorg STI Sport packs a turbocharged 2.0-liter gasoline engine producing 296 horsepower and 295 lb-ft of torque. The next-generation version could get a small power boost, but this hasn't been confirmed yet. The new version of the regular Subaru Levorg will go on sale in Japan in the second half of 2020, so the STI Sport version probably won't arrive until sometime in 2021.
