Maybe its a Sonic themed version of the classic Sumo game 'Super Rub a Dub' that game would play perfectly on a Switch by tilting the tablet and jerking the tablet to jump.
I hope it isn't a more serious racing game but with Sonic characters I can't imagine that working that well as a concept. Sumo has worked on the Forza games including Forza 7 so they have a pretty good track record with racing games. I remember them when they were Gremlin Graphics and had some of their MSX games.
