Car and Driver wrote:Using the foundations of the compact Kia Forte sedan, the design was developed for maximum aerodynamic efficiency, as well as eye appeal. The high tail, low ride height, and single flat panel covering the underbody components, plus the absence of side mirrors combine to deliver a drag coefficient of just 0.25. At highway speeds, a panel automatically deploys at the rear to enhance aerodynamic performance, as well as stability. Rear and side-view functions are handled by cameras.
Motive power is supplied to the front wheels by a 1.4-liter gasoline direct injection four-cylinder engine and/or a 78-kw (105-hp) electric motor. A lithium-ion polymer battery pack powers the motor, with enough energy on a full charge to propel the car 50 miles in pure electric mode. However, the Ray is also capable of running on its gasoline engine alone, or with a combination of gasoline and electric power, according to Kia.
Like other gasoline-electric hybrids, the Ray uses its transmission and regenerative braking to recharge its battery pack. Unlike most others, its big, all-glass roof is embedded with solar cells that also contribute to battery charging, as well as interior cooling. (The Fisker Karma will incorporate roof-mounted solar cells and the current Toyota Prius offers them as an option.) A set of 20-inch, 195/50 low-rolling-resistance tires enhance efficiency.
Thanks to its glass roof, the Ray’s interior has an open feel, and features lightweight materials with an emphasis on recyclability, as well as minimalist design. The steering is drive-by-wire and all secondary control functions are operated by touch screen—no buttons, no rotary knobs.
A hood-mounted gauge keeps the driver informed about the battery pack’s state of charge, and Kia’s new UVO system keeps occupants entertained. UVO is an infotainment system similar in concept and function to Ford’s Sync system. The similarities are predictable given that both systems were developed in concert with Microsoft.
