Ford has debuted two hybrid versions of its C-MAX MPV at the North American International Auto Show (NAIAS) in Detroit, only days after showing its first all-electric passenger vehicle at the Consumer Electronics Show in Las Vegas.

Describing the three new models as part of an electrification strategy that "emphasises consumer choice", Ford rolled out both a hybrid and a plug-in hybrid version of the C-MAX, both of which will be available by 2012 in North America and 2013 in Europe.

It says that the C-MAX Hybrid will deliver better fuel efficiency than the Ford Fusion Hybrid, which is rated at 36/41 (city/highway) mpg by US authorities, thanks to the use of lighter, smaller lithium-ion batteries.

The C-MAX Energi, Ford's first plug-in hybrid, will be able to run for more then 500 miles (800 kilometres) using both engine and battery, more than any other plug-in or extended range vehicle - and crucially, more than the Chevrolet Volt.

Like other electric vehicles, it will be charged from home and can "easily" recharge to 100 percent overnight on a standard household power outlet, perhaps making it more attractive for consumers unwilling to install the expensive home charging equipment which is recommended for all-electric vehicles.

Although Ford already has 140,000 hybrids on the road, its latest three vehicles have shown the automaker's determination to not be left behind across any of the emerging "green" engine technologies currently led by Toyota (hybrids), Chevrolet (plug-in hybrid) and Nissan (electric vehicles).

It plans a further two hybrid vehicles which will be released in 2012 and 2013, although neither have been named.
