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.

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 Mercedes-AMG E53 Hybrid 4Matic+ is a superb blend of high-tech hybrid muscle and cossetting top-end luxury. Value is competitive, it looks (and feels) the business, despite the conventional sedan configuration it’s surprisingly practical (except for the modest boot), fuel-efficiency is a key benefit and safety is stellar. The ownership proposition is okay for the category but that’s not top of mind when an enticing series of corners ranges into view. It’s an impressive package.
