Nissan has announced that it will debut its own hybrid system, over a decade after competitors have already been selling the vehicles.

The Japanese automaker may be late to the hybrid game, but the company says that its patience has paid off in the form of more effective hybrid technology. According to Reuters, Nissan’s in-house developed system features a single electric motor that detaches from the gasoline engine when fully charged, allowing travel on purely electric power. In addition, its battery is made of lithium-ion, a lighter and more efficient option than the nickel used in vehicles like the Toyota Prius.

Nissan will debut the features on its upcoming Infiniti M hybrid. A spokesman for the automaker says that the car will get at least 60 to 90 percent better fuel economy, and hopes to double its EPA-estimated mileage per gallon. The company also plans to begin selling its all-electric Leaf model in December.

Although lithium-ion is lightweight, it is also more expensive than its nickel-metal counterparts. Those who want a more affordable hybrid vehicle may want to search for a used Toyota Prius.
