2026 Tesla Model 3 Summary

It’s been in Australia since 2019 and despite the arrival of a comprehensively upgraded version in late 2023, the Tesla Model 3’s once gargantuan popularity has been declining in recent years.

A seemingly never-ending influx of pure-electric alternatives, primarily from China, has eroded the mid-size sedan’s positioning as the go-to, best-value EV choice.

But to its credit Tesla has again evolved the Model 3 proposition with the introduction of this Long Range Rear-Wheel Drive grade in October last year, at the time positioning it as “the longest-range EV in Australia”.

Since then, Tesla has adjusted the model grade name to Premium Long Range Rear-Wheel Drive.

Some additional tweaks, made in response to customer feedback, also illustrates the EV pioneer’s determination to step up in the face of increasingly fierce competition.

So, does this latest Model 3 do enough to earn a spot on your electric vehicle shopping list? We spent a week behind the wheel to find out.

2018 Kia Optima Summary

There are plenty of reasons why you should still consider a mid-sized sedan like the Kia Optima. I’m sure there are… just let me think about this for a sec…

Okay, so this part of the market is dying. A decade ago, sedans like this were really popular, but now there are heaps of alternative options. Yep, people are going for mid-sized SUVs rather than mid-sized sedans like this.

But that doesn’t mean models like the just-updated 2018 Kia Optima are without their reasons for being. I’m just not sure the facelift has made it more appealing to look at…

Verdict

Tesla has done enough with the introduction of this Premium Long Range RWD variant to keep the Model 3’s head well and truly above water in an increasingly competitive segment. After more than six years it still looks good, with a pleasant cabin environment, plenty of performance and leading energy efficiency. Safety is top-shelf and it stands up well in terms of practicality and driving dynamics.

That said, the ownership proposition is average, the determination to make so many functions screen-based is frustrating and the optional Full Self-Driving system is unconvincing. With the Model S and Model Y now discontinued globally it will be interesting to see how the Model 3 continues to evolve.

Verdict

If you travel long distances, want a good amount of space and don’t want to pay big bucks for a new car, then yeah, maybe there is a reason sedans like this will hang around for a while longer.

Sure, the appeal of sedans mightn’t be as strong as it once was, but models like the Kia Optima prove they still have a reason to exist.
