A Porsche expansion is planned for Forza Motorsport 6, based on a leaked Amazon listing.

One of the moderators of the Forza Forums spotted the leaked listing for the "Forza Motorsport 6: Porsche Expansion" posted on the online shopping website. The listing was already edited to remove the details, but AllGamesBeta managed to get a screenshot containing all of the information regarding the upcoming the Porsche expansion.

According to the Amazon listing, an "all-new guided Porsche Anthology campaign experience" will come out with 48 new events.

It will also come with 20 Porsche automobiles including nine different models that will be introduced on the Xbox One for the first time. Some of the new Porsche models that will be featured in the expansion include the car maker's early innovators such as the 1957 356A Speedster, as well as groundbreaking automobile technology inventions like the 2015 Team 919 Hybrid.

Players will also have the chance to compete in brand-new Porsche-themed multiplayer Leagues, Hoppers, and Rivals events.

The upcoming Porsche expansion pack will also introduce the Virginia International Raceway as the game's latest track. This classic American race track comes with seven distinct ribbons that feature both the night and wet configurations, which can run at 1080p and 60 frames per second.

Players can also gather a lot of Porsche exclusive mods and badges, as well as 250 Gamerscore worth of new achievements.

The listing also mentioned that the "Forza Motorsport 6: Porsche Expansion" will be worth $19.99 when it comes out.

However, Microsoft and game publisher Turn 10 Studios are still mum about the details of the expansion.

The news about the collaboration between Porsche and Forza first came out in June 2015, when Forza's community manager John Schommer revealed that Porsche was coming to "Forza 2."

"We're excited to share that we are working together with Porsche and EA to deliver the Porsche experience to 'Forza Motorsport 6' players in 2016. We'll have more details to share in the future on the integration," the post on the official Forza Motorsport website said.

The official announcement for the "Forza Motorsport 6: Porsche Expansion" is expected to be released in the coming days.
