2021 Audi S4 Summary

Audi would probably prefer you not to realise this, but the five distinct versions of S4 and S5 on the market all pertain to a single performance and equipment formula spread across five different bodystyles. 

Yes five, and this has been the case for more than a decade, with the S4 sedan and Avant wagon, A5 two-door Coupe, convertible Cabriolet and five door liftback Sportback all representing vastly different shapes for you to choose from, with the same underpinnings. This simply echoes the A4 and A5 ranges they’re based on of course, and BMW clearly thought it was a good idea too, given the 3 and 4 Series ranges were split into individual lines at the start of last generation.

Mercedes-Benz offers a similar array, minus the liftback, but is happy to wrap the whole lot under the C-Class label. 

So, given that the A4 and A5 range scored a mid-life update a few months ago, it’s only logical that the changes flow on to the performance S4 and S5s, with the top-tier RS4 Avant following suit. 

We’ve covered the latter in October, and now it’s the turn for the former, and CarsGuide was among the first to drive the updated S4 and S5 ranges at their Australian media launch last week.

2026 Polestar 3 Summary

Sometimes, a vehicle facelift doesn’t amount to much. Maybe a nip here, a tuck there, but to be sure you’re looking at the new version, you need to check the badges.

To be honest, the revised Polestar 3 SUV is a bit of that, with very little to visually distinguish the facelift from the previous car. But underneath there are some serious upgrades which, in that oh-so-Swedish understated way, serve to make the Polestar 3 an even more tantalising prospect.

The Polestar 3 has now moved to 800-volt technology which not only allows for faster charging, it also opens up the prospect of even more performance. A new generation of lithium-ion batteries also means greater range potential.

But it’s nice to see that Polestar hasn’t limited its attention to the drivetrain; there’s now a revised anti-roll-bar system and a recalibration of the power steering assistance. Which just goes to show that even though brands like Polestar trade on being an all-electric solution, there are still some engineers in Sweden who know how the rest of a car should work.

Meantime, the medium-large SUV space is a very crowded one right now, so the question is whether the new tech – invisible as it is – is enough to keep the Polestar 3 carving out its slice of that market.
