This is a really topical question right now, and the fear is that you could buy something today that would be technically obsolete next week. However, if you look at the way alternative powertrains (hybrids and EVs) have progressed over the years (and it’s been decades since the Toyota Prius introduced us to the hybrid principle) that hasn’t happened yet. Nor is it likely to.

Obviously, the best way to future-proof your purchase is to buy the latest tech. So that would be an EV. But even then, future EVs will be better than today’s models. That’s just progress for you.

The other factor is how you use your car. If you only drive in an urban setting and can recharge at home, then an EV makes plenty of sense. But if you live or drive in regional areas, then a conventionally powered car remains a valid choice. If your driving is mainly urban running with the odd long-distance trip thrown in, then a hybrid is the one that makes most sense.

As to whether you wait a few months, if you plan to buy a popular make and model, you’ll be waiting anyway. The global shortage of silicon chips as well as manufacturing bottle-necks due to Covid and other factors means that car-makers are struggling to keep up with demand.

The cost will depend on where you get the replacement, sometimes there are more affordable options than your dealer. You can read more about how to replace your car keys here.

The early Prius was a bit dozy from the lights but before you defect you should try the new model, which is more lively.
