Mercedes-Benz G63 vs Audi Sq8 E-Tron

What's the difference?

Everything you need to know about the Mercedes-AMG G 63's personality pokes out from underneath the polished alloy steps running down each of its flanks. Side pipes… no one does side pipes.

A colleague was pulled over in a G 63 because the cops thought the '60s muscle car-style exhaust was after-market and illegal. But it's not, and it's brilliant.

Launched globally in early 2018, this brutal take on the second-generation Mercedes-Benz G-Class might look the same as the G 63 it replaces, but under the skin it's a whole new ballgame.

The first-gen was like grandpa's axe, regularly updated but underneath it all the same basic framework. This is a whole new axe, including a fresh drivetrain, suspension set-up and interior treatment.

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.
