In the U.S., everyone is eagerly awaiting the 2013 Los Angeles Auto Show->ke211 to open its gates, but Japan has its own big show -- the 2013 Tokyo Motor Show->ke1834 -- coming up too. It is in its home country that Nissan ->ke62 plans to introduce two sports car concepts that will wow the world: one developed as a "crazy concept" and a second that will closely represent a production vehicle.

According to WhatCar, the second vehicle will gauge the market for a competitor to the Toyota GT 86, with design elements inspired by an earlier Nissan model.

If you are all anticipating a new 240Z, you can put that to bed, as a Nissan insider confirmed that this is "not a Z car->ke2077." Other that that, the insider remained mum on the car's details.

For now, this concept's goal is to test peoples' reaction and if everything goes well, we expect Nissan to put it into production in the upcoming years. To put it in line with the GT 86/BRZ/FR-S triplets, Nissan will likely fit this sports car with the same 197-horsepower, 1.6-liter turbocharged engine found in the Nissan Juke Nismo.

Full details on this new concept will be revealed during its official debut in Tokyo, so stay tuned!

2011 Nissan Esflow

Nissan unveiled the Esflow at the 2011 Geneva Auto Show. It was designed as a concept car that combined an electric engine with a rear-wheel-drive setup and a stylish exterior look.

The Esflow was powered by two electric motors, each developing 107 horsepower, with one controlling the left and the other the right wheels. The electric motors are powered by lithium-ion batteries placed just in front of the rear axle. These batteries are capable of providing power to the concept car for around 150 miles on one full charge.

The system allows the Esflow to run from 0 to 60 mph in just under 5 seconds.
