No doubt that the Mercury Mariner Hybrid is almost identical (at least its powertrain is) to its sibling from Ford, the Ford Escape Hybrid. But interestingly enough the Mariner Hybrid model has done pretty well for itself since it was launched in the US market in 2006. Like the Escape, the Mariner Hybrid is a "full" hybrid electric system, meaning it can switch automatically between electric power, gasoline engine power, or a combo of both. Pretty cool.
The Mercury Mariner Hybrid has even been delivered by Ford to former US President Bill Clinton. The Mariner Hybrid contained custom features suitable for a president, which included LED lighting, a 110-Volt outlet, rear bucket seats, a center console and rear seat that converts into a writing desk, and a refrigerator.
