Also keep in mind that overall light duty vehicle sales were pretty much flat. According to Autodata, October 2009 saw 838,052 units sold, while October 2008 had 838,156.
Why is this significant? Hybrids managed this increase despite relatively low gas prices and a slumping economy.
Toyota, not surprisingly, sold the most hybrids (18,757 units), a 15% increase year on year, while Ford followed in second (2,282 units) with a 14.3% increase year on year.
