Audi Sq8 E-Tron vs Mercedes-Benz GLS

What's the difference?

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.

It’s fair to say Mercedes-AMG GLS63 buyers really want it all; good looks, cutting-edge technology, seven-seat practicality, leading safety and V8 performance to name a few key desirables. And, lucky for them, the new model is finally here.

Yep, the latest GLS63 is yet another exercise in excess, leaving very little to be desired by its buyers. Indeed, it ticks almost every box when it comes to a utility vehicle that well and truly puts the sports in Sports Utility Vehicle.

But, of course, this raises questions over whether or not the GLS63 is trying to do too much. And given this model does a whole lot more than its predecessor, these questions need to be answered again. Read on.
