The 2013 Tokyo Motor Show last week featured unusual concepts that could be the cars of the future. While the auto showcase is renowned for its fantastical concepts, this year's event included vehicles that seem well within the realm of possibility, Forbes reported.

"The concept cars are as creative as ever, and the Japanese automakers are working on some jaw-dropping technology," the outlet said.

As autonomous driving comes closer to reality, "what once might have come across as far-fetched seems more like far-seeing," Forbes said.

One intriguing new concept is Toyota's FV2, short for "Fun Vehicle 2," which uses the driver's body movements for direction and changes exterior color according to the driver's mood.  The FV2 concept lacks a steering wheel, gas pedal and brake, relying solely on shifts in body weight for direction.

Toyota compares the car's "steering" of sorts to a Segway. The concept also has a clamshell-style top that stays open if the driver is standing up and closes when the driver sits down.

Sports car fans should look to the all-electric Nissan BladeGlider concept for the next big thing. The Japanese automaker plans to build a production version of the new vehicle, which has an aerodynamically efficient triangular shape.

The concept's unique build deposits 70 percent of the vehicle's weight on the rear wheels, putting the driver in the middle of the car with two passengers seated behind.

As automakers seek to transition to zero-emissions vehicles, concepts like Mitsubishi's XR-PHEV are a look at the near future. An update on the bestselling Outlander Sport, the XR-PHEV concept is also "sporty and urban," but it can run on electricity. The plug-in hybrid electric vehicle has a 1.1-liter three-cylinder turbocharged gasoline engine and an electric motor.
