2009 Chrysler Aspen And Dodge Durango Hybrids Begin ProductionSThe 2009 Chrysler Aspen HEMI Hybrid and the 2009 Dodge Durango HEMI Hybrid, the first hybrids from the penta-star brand, are finally rolling off the lines in Newark, Delaware. With its two-mode hybrid system and cylinder deactivation capability reigning in the big 5.7-liter HEMI engine, the hybrid twins are expected to return a 25% increase in fuel economy, up to 19 MPG city, 20 highway. Yes, even though they've been hybridized, they can still tow 6,000 pounds, along with all your rugrats and their junk. We suspect the market for these vehicles will be pretty strong, and sales may swell into the hundreds. [MotorAuthority]
