It’s safe to say that you’ll need the base Performance car for this to work, since the upgrade package focuses on easier-to-change features like the speed limiter, the addition of a carbon fiber spoiler, an improved suspension and higher-end wheels. You won’t suddenly turn your single-motor Model 3 into a beast. All the same, this is an important move — you won’t be locked out of perks like Track Mode just because you weren’t quite sure about an option the first time around.
We’re working to provide an aftermarket Performance Upgrade Package when Track Mode becomes available
