and Mariner vehicles we sell, one of them is a hybrid, and the appeal is growing,” says Sue Ciscke, Ford senior vice president, Sustainability, Environment and Safety Engineering. 2010 changes For the 2010 model year, the Mariner added Ford's MyKey and trailer sway controls as standard on all trim levels. The Mariner also saw the addition of Flex-Fuel, the ability to run using E85 fuel or regular unleaded gasoline with the V6 engine. Mercury removed the Euro-style turn signal repeaters for this model year. 2011 changes For the 2011 model year, the Mariner featured HD Radio as a standard, but continued with the same features as the 2010 models. This version of the Mariner was its last, as Ford discontinued the Mercury brand due to declining sales. Ford ended production of the Mariner in October 2010. The last Mariner rolled off the assembly line on October 5, 2010. Variants Hybrid The Mariner Hybrid powertrain was identical to its sibling, the Ford Escape Hybrid. It was launched to the U.S. market in 2006 and was discontinued in 2010 with the rest of the brand. The Mariner hybrid sold a total of 12,300 units. Like the Ford Escape Hybrid, the Mariner Hybrid is a "full" hybrid electric system, meaning the system can switch automatically between pure electric power, pure gasoline engine power, or a combination of electric battery and gasoline engine operating together, for maximum performance and efficiency at all speeds and loads. When braking or decelerating, the Mariner's hybrid system uses regenerative braking, where the electric drive motor becomes a generator, converting the vehicle's momentum back to electricity for storage in the batteries. With , the Mariner Hybrid has nearly the same acceleration performance as the conventional V6 Mariner. Again, just like the Escape Hybrid, it gets a respectable average of and is sometimes said to be the most fuel efficient sport utility vehicle on the road.
