The 2015 Tokyo Motor Show is just ramping up but already we’ve seen a new rotary-powered sports car from Mazda, a flagship sedan concept from Lexus and a new sports car developed together with McLaren F1 designer Gordon Murray from Yamaha.

The rotary-powered sports car is the RX-Vision. It’s a concept that Mazda built to preview a next-generation rotary powertrain that the automaker will eventually put into a production car.

The new flagship sedan concept is a preview of the next-generation LS due out next year. It packs a fuel cell powertrain, hinting that a fuel cell-equipped LS may be in the works.

Yamaha has a sports car concept that’s built around the iStream Carbon chassis devised by Gordon Murray’s design and engineering skunk works. The two-seater coupe weighs just 1,653 pounds.

You'll find all of these stories and more in today's car news, right here at Motor Authority.
