Mazda RX-Vision
Vehicle type: Coupe
Engine: Next-generation 16X rotary
Who designed it: Mazda design chief Ikuo Maeda
What's cool: An absurdly low and long hood, enabled by the compact packaging of the rotary engine, and LED accents that hearken back to the old RX-7's pop-up headlamps
Will it be built: It all depends on the engine. Engineers must solve problems with the rotary's fuel economy, emissions and reliability.
Show reaction: Supercar buzz. Aston Martin CEO Andy Palmer posted pictures of the RX-Vision on Twitter, calling it his car of the show.
Mitsubishi eX
Vehicle type: Compact EV crossover
Engine: Twin electric motors, 45 KwH battery pack
Who designed it: Tsunehiro Kunimoto, general manager of design
What's cool: Automated features such as driverless valet parking, camera feeds in place of mirrors and a 248-mile range on a full charge
Will it be built: Not as such. Mitsubishi plans to add a third crossover to its range, slotted between the Outlander and Outlander Sport, and the design of the eX will inform one of the smaller two. Plus, all future Mitsubishi crossovers will have PHEV or EV variants.
Show reaction: Subdued. Neither electrified vehicles nor compact crossovers stand out today.
Subaru Impreza 5-Door Concept
Vehicle type: Compact five-door
Engine: 2.0-liter four-cylinder Boxer with 145 hp
Who designed it: Atsushi Kochi
What's cool: Concept shows new design language, "Dynamic & Solid" Subaru, with softer, sleeker and more rounded proportions
Will it be built: Yes, starting mid-2016 in Subaru's Indiana factory
Show reaction: Styling turned heads; kudos for sleeker look
Nissan IDS Concept
Vehicle type: Four-door hatchback
Powertrain: 60-kilowatt-hour battery
What's cool: Nissan is pondering what electric vehicles will look like and how they will perform in the near future. The IDS is an autonomous-drive vehicle that uses cool blue interior lights to stimulate concentration and a changing LED body line that shows pedestrians the car's intentions.
Will it be built: The concept signals what the next-gen Leaf could look like.
Show reaction: Nissan has managed to re-excite people about an EV.
Lexus LF-FC
Vehicle type: Full-size sedan concept
Engine: Hydrogen fuel cell
Who designed it: Takeaki Kato, project general manager
What's cool: Sleek styling softens current Lexus look, awd powertrain with two hydrogen tanks and trunk-mounted fuel cell stack
Will it be built: The car previews the next-generation LS, so yes, but with more traditional gasoline and hybrid powertrains. A fuel cell version is being considered.
Show reaction: Universally praised as one of the show highlights
