Turn 10 Studios content director John Wendel confirmed the specs, saying he believed the studio is "uniquely positioned" to deliver on the benchmarks.
"We're a huge epic game that's going to be running at 1080p, 60fps on the next-gen console, so it's an incredible opportunity on one hand, but you have to be incredibly flexible and agile and self-aware on the other hand," Wendel told Gamespot.
Forza 5 will be available at launch exclusively for the Xbox One.
New Forza 5 footage and details is likely to emerge next week at E3. Microsoft's press conference takes place June 10 at 10am Pacific time at the Galen Center in Los Angeles.
