2005 hybrid share of global market is 0.5%, but this is set to stagnate at a maximum of 3% as the cost of hybrids is greater than that of other types of drivetrain. Much of the increased cost is due to the power-electronics which are heavy, bulky, expensive and require complex cooling arrangements.
Today these rely on silicon, but new silicon-carbide based electronics will allow at least 50% weight and size savings with no need for a cooling system.
"....these technological advances are expected to be integrated into HEVs during the next three to five years, and together they should lead to lighter, smaller, and more fuel-efficient cars that will in turn promote further growth in this industry."
