fuel efficient car

The Jeep Renegade combines a lithium-ion battery pack with a small-displacement BLUETEC diesel engine, which together help it achieve a fuel economy of more than 110 miles per gallon.

AFS Trinity Power has developed two fully operational XH-150 SUV prototypes using off-the-shelf components that make it possible for plug-in hybrid electric vehicles to achieve 150 MPG, go 40 miles in all-electric mode, and use gasoline for additional unlimited miles in hybrid mode. The low-cost lithium batteries -- protected from excessive resistive heating by the ultracapacitors -- will make the XH-150 much less expensive to purchase.

Nissan has been building their Altima hybrid cars at their Smyrna, Tennessee plant, which has the capacity of building up to 50,000 vehicles. If demand for the Altima hybrid is great enough, Nissan may just offload some production of the traditional Altima cars to their plant in Canton, Mississippi.
