The Hot Wheels id Smart Track Upgrade Kit is designed for those who already have the Race Portal. The Upgrade Kit with the Race Portal and the Hot Wheels id app allows you to collect and race your id cars physically and online.
Premium track pieces include connectors, curves, straights, ramps, a finish line, and a loop. It also has a high-performance booster where the Race Portal will dock.
When combined with the Race Portal, the Upgrade Kit lets you see your track layouts live in the app as you assemble the pieces. There are more than 20 premium track configurations and over 100 app challenges to go with them.
The Smart Track Upgrade Kit combined with the Race Portal is almost identical to the Smart Track Kit. The only differences are the exclusive vehicles. The Race Portal comes with a Twin Mill and a GT Hunter. The Smart Track Kit has a Rally Finale and the Super Blitzen.
