Oh sure, the technology packed into the Mercury Mariner hybrid is astonishing, which is why Ford Motor Company has 40-plus patents shared on this SUV and its sister vehicle, the Ford Escape hybrid. In basic terms, the core attributes that make this a hybrid vehicle are the 2.3-liter Atkinson cycle engine teamed with two AC electric motors, an electronically controlled continuously variable transmission, and 250 “D”-size nickel metal hydride batteries. The result is the possibility of traveling on just the electric motors, or a mix of electric motors and gasoline engine power – which in heavy acceleration mode is fairly close to the power generated in the non-hybrid Mariner’s 3.0-liter V6 Duratec engine. But hybrid Mariner is more than a technology-laden vehicle. Yes, it’s a good fuel economy vehicle – getting approximate per gallon numbers of 32 city/29 highway – on the 4WD version. And the hybrid Mariner looks like the regular Mariner, expect for a few changes: 16-inch/5-spoke wheels, hybrid badges, and rear quarter window air vent. But what’s extra nice is Mariner hybrid is just a darn good vehicle. There are only minor tweaks for the 2007 model year: two new colors as well as an available safety package that provides a side air curtain system and seat-mounted airbags. The hybrid Mariner’s Hybrid Energy Audio and Navigation system lets driver and riders see the flow of energy on a 4-inch dashboard screen. Mariner hybrid is a fun trip. MSRP of the hybrid with 4WD is $27,895.
