By John O'Dell, Senior Editor Spurred by factory incentives, replenished stocks and the relative freshness of several models, sales of hybrid-electric cars and SUVs soared in October, easily outperforming the market as a whole. Compared to October '08 – a month with six fewer hybrid models available – sales of Ford, General Motors, Honda, Nissan and Toyota hybrids were up 12.1 percent, while sales of conventionally powered cars and trucks were flat. The one-month picture was even rosier, as October hybrid sales jumped 22.5 percent from September's, versus a 12.1 percent hike in sales of conventional models. Nissan, which has only one model – the Altima hybrid, – and sells it in just the nine states with the toughest emissions standards, was the only hybrid maker to record a sales decline for both periods, dropping 46 percent from a year earlier and 13 percent from September. As with most hybrids – Toyota's Prius excepted – Nissan's actual numbers are quite small because of low sales volumes. October's sales drop represented just 46 fewer Altima hybrid sales than in September. Toyota's redesigned 2010 Prius, sweetened by a small factory incentive, remained by far the segment leader, accounting for 55 percent of all hybrid sales for the month.
