What's cool: Sensually rounded body work enlivened by spunky, high-tech powertrain
Who designed it? Yasutake Tsuchida
Will it be built? Yes, in some form. This concept hints at a next-generation Mazda3 hatchback, and Mazda has said the new design language and Skyactiv-X engine will arrive in 2019.
■ Mitsubishi e-Evolution Concept
Engine: Three electric motors of unknown size or power. One at front axle, two at rear wheels.
What's cool: Digital screen at base of windshield spans width of interior and projects additional visibility with navigation info augmented over it
Who designed it? Tsunehiro Kunimoto oversees design direction.
Will it be built? Not in this form. Rather than foreshadowing a specific model, the e-Evolution is the latest design direction and technological showcase from Mitsubishi. The closest production model will be the next-generation Outlander Sport, which isn't due for several years.
■ Subaru Viziv Performance Concept
Engine: Subaru's trademark boxer engine and symmetrical all-wheel-drive system
What's cool: Winglets on the wheel arch lips improve aerodynamics and handling.
Who designed it? Atsushi Kochi
Will it be built? Yes, but probably in a toned-down way. Subaru says it will inform the looks of next-generation vehicles, but the concept seems to clearly foreshadow a WRX.
■ Nissan IMx
Engine: Battery-run twin electric motors will put out 420-plus hp.
What's cool: The IMx, a fully autonomous electric crossover, is the template for Nissan's vision of post-2020 autonomous driving. Inside are four movable seats set in a Japanese-influenced interior with panoramic views of the world outside. In autonomous drive, the steering wheel retracts into the dashboard, and the seats recline for greater relaxation.
Who designed it? Satoru Tai, Nissan executive design director
Will it be built? Probably, eventually, but not with the IMx name. It could become the next generation of an existing crossover nameplate. Or it could become the SUV companion to Nissan's Leaf.
■ Lexus LS+ Concept
Engine: Twin-turbo V-6 or nonturbo V-6 with hybrid system
What's cool: The modified LS is envisioned with the company's Highway Teammate system, which will enable automated driving on expressways, from on-ramp to off-ramp, by 2020.
Who designed it? Lexus Japan design
Will it be built? Likely in some fashion. Lexus is imagining what a future refresh of its production flagship sedan will look like, and limited self-driving abilities on the highway are feasible by its target date.
