Audi RS Q8 vs Audi Sq8 E-Tron

What's the difference?

Not to spoil the illusion, but at their core the Lamborghini Urus, Bentley Bentayga and Porsche Cayenne all share the same base mechanical DNA. And yet despite their huge price tags and enviable reputation for performance, the fastest SUV isn’t one of them - it’s an Audi.

The new Audi RS Q8 Performance, to be precise, which has lapped the famous Nurburgring in Germany in record time, usurping the Cayenne Turbo GT in the process.

Boasting the most powerful internal combustion engine Audi has ever installed in a production car, ceramic brakes and a highly advanced suspension package, the RS Q8 Performance takes the German brand’s SUVs to a new level of, how do I put this… performance.

So it’s an appropriate name, but is it an appropriate car for Australian buyers looking for something fast, spacious and special? Read on to find out…

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.
