Nissan decided a while ago that it wanted to develop its own hybrid system, which is why it ended its deal with Toyota that saw a short-lived and generally unsuccessful Altima Hybrid that used Toyota's Synergy Drive system. Now, already two years behind its original schedule, USA Today confirms that Nissan is aiming to add a hybrid option for the new Altima in two more years.
Plenty of rumors surround the Altima Hybrid's powertrain, but few facts are known at this point. A plug-in system is a likely option, while early reports have suggested that a supercharger could provide additional propulsion.
