The carmaker will increase the number of Ford Fusion Hybrid test vehicles from 10 to 30, claiming that this will give it the largest fully autonomous vehicle fleet of all automakers.

Ford will also accelerate the development and testing of its virtual driver software in both urban and suburban environments

“Using the most advanced technology and expanding our test fleet are clear signs of our commitment to make autonomous vehicles available for millions of people,” said Raj Nair, Ford executive vice president, global product development, and chief technical officer. “With more autonomous vehicles on the road, we are accelerating the development of software algorithms that serve to make our vehicles even smarter.”

The latest vehicles represent Ford’s third-generation autonomous vehicle development platform, and are based on Ford Fusion Hybrids, similar to the second-generation platform.

Ford recently announced that its fully autonomous cars will take to the streets of California this year. The company already tests autonomous vehicles at its proving grounds, as well as on public roads in Michigan.
