Forza 5: "We're using 100% of this console" - Greenawalt on Xbox One

Turn 10's Dan Greenawalt has told VG247 that his team is already using "100%" of Xbox One to develop Forza Motorsport 5, adding that he expects his team will become better at using that power over the course of the console's lifespan.

Speaking to VG247 at Eurogamer Expo 2013, Greenawalt said, "Trying to be there at launch means we're shipping our game at the same time the console is shipping, and it requires that kind of hand-holding between their team and our team.

"So in many ways, we're testing their OS, we're testing their architecture every day, so it's an incredible partnership. It's funny, because I hear it a lot: 'are you using the hardware?' The truth is, you always use 100% of the hardware. You just do, but it's a question of whether or not you're using it efficiently, and so that's what happens over a course of years."

Greenawalt also spoke about how his team learned to get more out of the Xbox 360 hardware over the course of several Forza games for the system.

"Between Forza Motorsport 2 and then three and four, the game got incredibly technical. The hardware didn't get any more powerful, but we got more efficient at doing our math. We're using 100% of this console, but obviously we will become more efficient over the years."

Greenawalt also revealed that the inclusion of Autovista cars in Forza 4 was Turn 10 testing next-gen car models ahead of time. The team was exposed to Xbox One two years ago during the process of consulting with the console architects and telling Microsoft what they wanted out of the next-gen system.

Forza Motorsport 5 is an Xbox One exclusive, launching alongside the console in November.
