Rumor has it that as spacey as this concept looks, its design points to a future city car from Mazda, due out in 10 years or so.  The Kiyora (Japanese translation: clean and pure) may not look production feasible, but beneath its wave-like exterior are several innovations that are or will soon be employed.  Not likely to be part of that list anytime soon is the specially-designed roof which channels rain water into the vehicle, through a purification system and into the cupholder for immediate consumption by passengers. 

Of more immediate use is Mazda’s newly developed Smart Idle Stop System (SISS) which saves fuel by automatically shutting down the engine when the vehicle is stationary, and is capable of a quick and quiet restart.  The 1.3-liter engine’s efficiency is further increased by the use of  improved direct-injection technology, newly designed combustion chambers that enable more precise ignition control and advanced dual sequential-valvetiming (S-VT). Most striking in the concept, is the body design; formed to resemble the shape of a water droplet on its side. 

This, along with a sophisticated underbody that controls wind swirl and a rear roof spoiler make for a highly aerodynamic form with a coefficient of drag that is over 10 percent lower that of the current Mazda2. The roof, which is transparent, has solar cells which provide electricity for the car’s interior systems.  The doors and side windows of the Mazda Kiyora are a single unit made of plastic, which provides the same transparency and refraction properties as glass, and the strength of a thin-panel door, but with far less weight. Touching the surface of the front tip of the door activates a sensor, which opens the doors up and away from the car.

The console display uses advanced touch-screen technology with tactile feedback.  Using liquid-skin display technology, it mimics the rippling that water makes when you touch it with your finger. When the car is off, the IP looks like ice, frozen and hard. When the car is switched on, the display appears to turn into water. Information icons would appear and float downwards to pre-programmed positions in front of the driver. The driver is able to move the icons around with his finger and organize them in any way desired.  From this touch-screen display, you can control a hard-disk drive with advanced sensors that provide environmental information like how much fuel you used and how many grams of CO2 you released into the atmosphere on a particular day. It can also calculate how many toxins the car filtered out of the air and water during the same period.  Finally, the low lines at the front of the car guide outside air into the car and through this charcoal, which filters out and captures toxins better than most filter systems, without the need for an electric fan or inorganic materials.  In total, the Kiyora Concept not only lowers its potential impact on the environment in as many was as possible, but is the most comprehensive vehicle conceived to address and monitor such elements.

The interior shapes not only maintain the water theme, but function to stiffen the passenger compartment with minimal weight. Lightweight materials such as aluminum and a special resin foam, which is under development at Mazda, are used not only for interior parts such as the instrument panel, but also for the hood, tailgate and sections of the chassis.
