2026 Genesis G80 Summary

Remember those extra-long Australian luxury sedans like the Ford Fairlane and Holden Statesman/Caprice?

The patriotic choice in an era where that mattered and further protected by tariffs on imports that made them barely any more expensive than a base mid-sized Euro like a BMW 318i, they dominated the top end of the market with their sheer size outside, vast space inside and big-six or V8 grunt.

Like they used to say, there is no substitute for cubic inches.

Well, the spirit of these beloved local social-climbing classics lives on in just one modern car in 2025, the Genesis G80. Over three generations since 2008, it has been Hyundai’s tilt at the premium establishment, in much the same way as the Fairlane and Caprice were, and Toyota’s Lexus luxury brand still is.

We take a dive into the latest petrol-powered range-topper version, the 3.5T All-Wheel Drive (AWD) Sport Luxury (SL), which gives off more than its fair share of vintage HSV Grange vibes.

2021 Mercedes-AMG E63 Summary

Feels like lately all the Mercedes-AMG buzz has been at the smaller end of the scale.

Most recently, the screaming GLA 45 S has arrived in Australia, pumping out more kilowatts and newton-metres than any compact SUV has a right to.

But here, we're doubling the cylinder count to eight, arranging them in a vee, and lighting the wick on AMG's powerhouse mid-size sedan, the recently upgraded E 63 S.

While the ferocious twin-turbo V8 and the rest of this beast's powertrain are unchanged, the car has been brought up to speed with some aero-focused styling tweaks, Merc's latest 'Widescreen' digital cockpit, as well as the MBUX multimedia system, and a tricky new multi-function sports steering wheel.

Verdict

Overall, then, the flagship G80 tries to be docile Clark Kent and the amazing Superman in one. As such, it stretches itself trying to be both a luxury GT and high-functioning sports sedan.

But while it doesn’t quite achieve either perfectly the Genesis gets near enough for most – especially at its exceptional price point.

Verdict

The E 63 S fills its niche in AMG's Australian line-up perfectly. More mature than the brand's four-cylinder hatches and SUVs, but not as overbearing as some of its bigger sedan, GT and SUV stablemates. And its ability to seamlessly switch between serene comfort and dynamic performance has nailed the objective for this 2021 update.
