>Cars are versioned by year/model, which again makes it pretty clear to understand minor/major updates. Sometimes significant updates are introduced in a model year, but generally the core features remain the same and it could still be considered an upgrade to that model.
Tesla managed to break this trend massively, which proves a problem for things like insurance. The feature set on (say) the January 2014 Model S is very different from the December 2014 Model S, even though they technically share the same "year".
