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 Audi E-Tron Gt Summary

It can be easy to dismiss electric cars as an imperfect solution to the world’s problems. But that would be missing one big point - they’re really, really fast.

Carmakers twigged that not everyone was enamoured with the environmental credentials of electric vehicles (EVs), especially luxury brands, and thus pivoted to the new sales tacit of performance and prestige.

Which is why Audi’s current performance flagship vehicle is not a mid-engined V10-powered replacement for the R8, but rather the all-electric RS e-tron GT. And for the new model year they have not only updated the range, bringing (you guessed it) more power, but also added a new hero model - the RS e-tron GT Performance.

It leads a new three-pronged line-up for the four rings brand, with the RS e-tron GT Performance sitting above the RS e-tron GT and the new S e-tron GT; the latter effectively replacing the previous ‘entry-grade’ model known only as the e-tron GT.

These arrive as part of a mid-life update for the model, with some minor styling tweaks (inside and out) along with enhancements to the battery and changes to the specifications.

The new range has just arrived in Australia and Audi will be hoping it can turn around the sales performance, which saw the outgoing e-tron GT and RS e-tron GT find just 84 customers in 2024. That was a decline of 75 per cent on 2023 sales, and nearly 200 less than the closely related Porsche Taycan.
