CES will host more than 500 companies that make tech aimed at the automotive industry. The roster includes major automakers such as Audi, Hyundai and Ford; the latter will showcase its EV+ technology. Originally announced in November, the technology allows a vehicle to learn a driver's favorite destinations and use the information to optimize power consumption. Available for Ford's C-MAX Energi and Fusion Energi plug-in hybrids, as well as the regular hybrid editions of Fusion and C-MAX, EV+ combines a vehicle's built-in GPS with proprietary software that identifies frequently visited locations and adjusts how power is stored in the battery. If a motorist is within 200 meters (about 0.12 miles) of home, for example, the car can remain in electric-only mode, with the internal combustion engine shut off. EV+ technology is part of a portfolio of around 500 hybrid-specific patents that Ford has accrued as it embraces the role software will play in modern vehicles. The company has a history of demonstrating compelling tech at CES, so EV+ might be just the tip of the iceberg for automotive aficionados attending the show.
