Hybrids are here to stay with the technology being integrated into more and more of the Toyota line up. At present, that includes the Prius, Camry Hybrid and Highlander Hybrid. In fact, Toyota sees hybrid technology as the core for what it calls "the ultimate eco car". This car of the future would be the result of combining technologies that include alternative energy sources, customized, high-performance internal combustion engines, electric power and fuel cells.

Among the most promising avenues being explored are Fuel Cell Hybrid Vehicles (FCHV). These vehicles use fuel cells where a reaction between hydrogen and oxygen produces electricity for both motors and driving power, with water as the only byproduct. Hydrogen is not only plentiful but is also friendly to the environment and will help reduce our dependency on oil.

At the same time, with the removal of the internal combustion engine, fuel cell technology allows a radical re-shaping of the cars we drive. Fuel cells produce little heat, noise or vibration and can be placed anywhere in a vehicle. Because engineers and designers don't have to concern themselves with creating physical linkages between engine and wheels, the usual design restrictions need not apply, and they can concentrate fully on ensuring passenger comfort and safety.
