CINCINNATI — The Kroger Co. said it has picked Scottsdale, Ariz., as the test market for a grocery delivery service using self driving vehicles.

Kroger had previously announced a partnership and Nuro to begin testing grocery delivery using Nuro’s technology. The company announced Thursday that the pilot will involve a single Fry’s Food Stores location at 7770 East McDowell Road in Scottsdale. Customers were able to begin placing delivery orders on Thursday, either via frysfood.com or the Fry’s Food Stores mobile app.

Grocery orders can be scheduled for same-day or next-day delivery, based on delivery slot availability, by Nuro’s fleet of self-driving vehicles. There is a $5.95 flat fee for delivery, with no minimum order size.

“We’re excited to launch our autonomous vehicle delivery pilot with Fry’s in Scottsdale,” said Kroger chief digital officer Yael Cosset. “Kroger wants to bring more customers the convenience of affordable grocery delivery, and our pilot with Nuro will help us test and learn to understand customer acceptance of autonomous vehicles in our seamless offering. We thank Arizona Governor Doug Ducey, Scottsdale Mayor Jim Lane, and the Scottsdale community for being terrific partners and for supporting customer-focused innovation.”

Mountain View, Calif.-based Nuro also endorsed Scottsdale as the ideal site for the pilot program.

“Arizona is home to some of the most innovative autonomous vehicle testing,” said Nuro Co-Founder Dave Ferguson. “We’re proud to contribute and turn our vision for local commerce into a real, accessible service that residents of Scottsdale can use immediately. Our goal is to save people time, while operating safely and learning how we can further improve the experience.”

Nuro will begin the pilot using its self-driving Toyota Prius fleet and will introduce its custom R1 driverless vehicle this fall.
