The development kit includes the native Application Program Interfaces (APIs) that allow developers access to more than 350 vehicle data signals—more than any other automaker. Those signals include:

• Instrument panel measurements, such as trip odometer and vehicle speed

• Drive information, such as presence of passengers or if the windows are open or closed

• Vehicle features, such as radio or backup camera

• Performance and maintenance, such as oil life and tire pressure

• Lights and indicators, such as a burnt-out lightbulb or low washer fluid

The NGI SDK mimics real vehicle data, allowing developers outside GM to build apps without making frequent trips to Detroit to conduct testing on infotainment modules.

GM has nearly 12 million connected vehicles on the road today, the largest fleet of any automaker. From 2015 to 2016, GM has seen data usage by customers increase nearly 200 percent. Mobile app use for GM vehicles also hit an all-time high in 2016, with more than 225 million interactions.

We want to let developers know that we are open for business. The possibilities for vehicle app development are truly endless and can focus on a variety of areas such as fuel efficiency, route planning and vehicle performance. Today’s vehicle app developers are early players in an uncluttered marketplace.
