2024 Audi Sq8 E-Tron Summary

Late last year, Audi gave its large SUV range a freshen up by stocking its showrooms with the Q8 55 e-tron model; a rebadged, facelifted full-sized electric SUV designed to go head-to-head with things like the Mercedes-Benz EQE.

As it turned out, the Q8 55 was destined to become the mid-spec model and now Audi has book-ended the Q8 range with the entry-level Q8 e-tron 50 and the flagship SQ8 e-tron.

And while the previous 55 model was available in Sportback and SUV (station-wagon) forms, the latter has now been dropped.

That leaves the 50 model as an SUV only, while the headline act – and the vehicle we’re testing here – the SQ8 can be had in either body style.

The reason we’re concentrating on the biggest, baddest, most expensive variant, is that’s precisely what Audi is tipping the Australian market will gravitate towards.

In fact, as many as 70 per cent of Q8-platform sales could be the SQ8. That’s in line with the Australian market’s fondness for spending up big on the sportiest version of many makes and models, but it remains a bit of an anomaly in the rest of the car-buying world. Nevertheless, it remains the reason we’re focussing on that variant here.

Of course, electrification has never been more important for a carmaker operating here since the New Vehicle Efficiency Standard was announced recently, and even though the Q8 range will be a small percentage of Audi’s sales here, any EV represent progress towards meeting corporate targets.

2026 Porsche Cayenne Summary

No good deed goes unpunished.

Porsche, a brand synonymous with petrol-guzzling sports cars, tried to do the right thing and make a nearly wholesale switch to electric vehicles by the end of the decade. The problem was, while this made governments happy, it didn’t sit well with customers.

Porsche’s all-electric Macan is enduring a torrid 2026, with sales down over 75 per cent now that all the petrol-engined options are gone. 

But that hasn’t stopped the German brand trying again with an all-electric Cayenne. However, there are some key differences that mean this latest electric Porsche won’t suffer the same fate.

Namely, the petrol-powered and hybrid versions aren’t going anywhere and new versions are rumoured to be coming in the not-too-distant future.

For now though, we have this all-new electric Cayenne - so how does it stack up to its predecessors as the sports car brand’s big SUV?  And will it be second time lucky for Porsche’s electric transition? Based on two rather unorthodox days of test driving, the verdict might surprise you…
