2021 Mercedes-Benz S-Class Summary

It's only in the running for the title of world's best luxury car. No biggie here, then.

Like Rolex and Concorde, S-Class has become a byword for ultimate, and deserved or not, the Mercedes-Benz defines its segment despite the best efforts of the BMW 7 Series, Audi A8, Lexus LS and (sadly now-defunct) Jaguar XJ, as well as pointing the way forward with new technologies that eventually trickle down to more proletarian models.

Replacing the half-million selling W222 unveiled in 2013, the W223 is the latest in a long line since the first W187 Ponton debuted in 1951, and includes the famous ‘Finnies' and Stroke-8 models that followed immediately afterwards, but it is the 1972 W116 that really set the template.

Now, seven generations in, the 2021 S-Class is all-new again, with progressive safety and interior features that should help keep it Australia's bestselling full-sized upper-luxury sedan.

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.

Verdict

Mercedes-Benz set out to restore the S-Class' place amongst the greatest sedans in the world.

In the heavily-optioned, near-$250K-plus S450 as well as the extended S450L at $300K as tested (the sweet spot of the range for now), we reckon the Germans have succeeded, pushing safety, comfort and technology boundaries, in a package that is true to the heritage of the series.

Tax-fuelled sky-high prices will certainly keep the S-Class niche in Australia, but the car is more than good enough to dominate its tiny corner of the upper-large luxury car sphere.

The best new car in the world? We reckon it's highly likely. Mission accomplished, Mercedes.

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.
