Ford will start taking orders for the Mercury Mariner hybrid in July to gauge demand before production begins. Ford, which has been selling the hybrid Escape since October 2004, will begin pre-selling the Mariner hybrid on July 11, when prices will be set, according to the company. Based on the hybrid powertrain from its cousin the Escape Hybrid, the Mariner Hybrid delivers an estimated 33 mpg (city), 29 mpg (highway) and is targeted to meet California’s Advanced Technology Partial Zero Emissions Vehicle standard.
