With more Sonic racing in the spotlight, of course NKOK comes right back out of the woodwork as well, with these new remote control cars.
For Team Sonic Racing, you can get Shadow in his Dark Speed car & Sonic in the Speed Star car. These are now 2.4 GHZ (the frequency that communicates from the remote to the car) which means you can race them against each other & they won't interfere with the signals.
Then, the new feature is 'turbo boost' which is likely that small switch or button in the middle of the controller. As is the standard, both cars have working headlights & do make noise.

The character figures look the same or very similar to previous figures they've had in the cars which were (proven?) to be based on the Jazwares figures' heads & hands. These are in the Sega Shop online in 2019, but they should also be coming to stores as well thanks to the popularity of Team Sonic Racing. RC cars like this make a lot of sense, and they look good to collect / on shelves if you like the design of the vehicles from the game.
