Project Motor Racing Confirms IMSA Licence, Teases Mustang GT3

With the 25 November release of Project Motor Racing just a few months away, we're getting rather excited about getting our hands on the sim. That excitement has just been ramped up as developer Straight4 Studios has confirmed it has secured the IMSA licence for the title, along with a teaser for the Ford Mustang GT3.
#ProjectMotorRacing joins forces with @IMSA and the prestigious WeatherTech SportsCar Championship.

The collaboration brings with it many of the US's greatest racing series past and present, and its two crown-jewel endurance events.

That comes off the back of recent confirmation that Porsche would be available in-game. Elsewhere, the game's full list of 30 achievements has surfaced via TrueAchievements, confirming several more tracks among the game's roster. Interestingly, it looks as if Silverstone wasn't the only official track licence that's been difficult to come by, as the list reveals several other stand-in names for well-known venues. Since these achievements centre around matching real-life pole laps, though, it's fairly safe to assume the layouts will be the ones we know and love.
Read on for all the cars and tracks confirmed to be in the game, plus a thing or two we've spotted in blink-and-you'll-miss-them scenes in trailers.
