Nissan recently announced that it will continue its efforts to strengthen its lead as the seller of the most pure electric vehicles than any other automaker with the introduction of new hybrid technology.

The electric vehicle market remains small, while the hybrid market is slightly larger, but represents a small percentage of new vehicles that are sold. Nissan realized this last year when the auto manufacturer killed off the Altima Hybrid last year, which went unnoticed by many consumers because Nissan is now able to provide vehicles that are just as fuel efficient without a battery.

According to Automotive News, a new Nissan-designed front-wheel-drive hybrid powertrain will be introduced in the Infiniti JX three-row crossover or a vehicle in the same class that is similar. It was also reported that there will be an average of one new hybrid model vehicle every year, including a plug-in model of the JX/CUV that will debut in 2015.

Nissan's electric vehicle advantage could be beneficial, as a result of global fuel economy requirements continuing to increase, which is why Nissan will have to spin its re-entry into the hybrid market since CEO Carlos reported in 2009 that Nissan didn't intend to play a leadership role in hybrids.

Nissan also recently introduced the Serena S Hybrid, which utilizes the company's hybrid powertrain. The Serena is the best-selling minivan, which is thought to be a result of the gas-electric version achieving around 36 miles per gallon, a 10 percent improvement over the non-hybrid model.

General Motors also recently announced plans to reveal its redesigned Chevrolet Silverado and GMC Sierra full-size pickups on December 13 in Detroit, according to the automaker's officials.

The Silverado 1500 hasn't been redesigned since 2006 and has easily been the automaker's best selling vehicle in the United States, totaling 298,200 units in the first nine months of the year.

"The bold exterior design of the new Silverado reflects the enhanced capabilities of the truck while features such as jewel-like, projector beam headlamps showcase the careful attention given to every detail," GM said in a statement.

The Silverado and Sierra are expected to be available to consumers in 2013, but will debut at the 2013 North American International Auto Show in Detroit in January, which might increase the performance in sales.
