Coming from Slightly Mad creative director Andy Tudor...
"The Wii U is more than capable of providing the core Project CARS experience. Sure, some super-high-level graphical effects may not be possible but in comparison it also offers a unique interaction experience via the GamePad controller, with the second screen potentially becoming your track map overview, rear-view mirror, telemetry, or simply mimicking a real race car steering wheel whilst you use the gyroscope to drive.
Plus there are great possibilities to extend our existing WMD community into the Mii Community with discussion and sharing of content and ideas. There’s no realistic racing game on the Wii U currently yet, and we hear the fans crying out for one. Project CARS provides a Forza or Gran Turismo-like experience for those gamers and it’ll be something to really show off what the system is capable of. From our internal playing, it’s looking extremely promising."
