According to a massive leak, the Mk4 Toyota Supra may not be the only car coming to Forza Horizon 4. Enterprising Forza fans on GTPlanet's forums have unearthed a large list of files in the game's code, each wearing the abbreviated name of a vehicle that has yet to appear in the best arcade racing game of all time. 

In typical Forza fashion, the leaked car list contains a diverse mix of machines including glossy car magazine cover stars like the reborn Alpine A110, McLaren Speedtail, and the Lamborghini Huracan Performante, vintage German fare such as the AMG Hammer and a Singer 911 as well as alternative stuff like the electric Jaguar I-Pace and a Bugatti Chiron made of Lego.

It should be mentioned that the presence of several dozen file names does not in any way guarantee that these cars will actually come to the Xbox open-world racer. While it's possible that we've stumbled upon the blueprint for another year's worth of downloadable car packs, it's equally likely that these have merely been included in the game's code as placeholders. 

Notably, however, 2019 is the first year since 2010 that an annual Forza game isn't being released with the franchise's development teams understood to be busy working on titles for next year's Xbox One successor, Project Scarlett. This gives Horizon 4 at least another year in its reign as the newest game in the series and presumably another year of steady content drops.

Another angle to consider is the fact that Project Scarlett's rival, the PlayStation 5, recently confirmed that it would be backward compatible with all PS4 games. Perhaps the next Xbox will end up following suit with a special, expanded version of Forza Horizon 4 serving as a launch title packing in an extra 120 cars?
