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.

2018 Hyundai I40 Summary

A wagon and not an SUV, eh? Respect. You see, when most people now think of a new car they think of an SUV, especially when they want something with a bit of cargo space. But not you.

And for thinking outside the box you’ll be rewarded with something that’s better to drive than most SUVs – like the Hyundai i40 Tourer in the Active grade and a diesel engine we’ve road tested here.

So, what are the strengths and weaknesses of this Korean wagon, and should you wait or buy it now? Read on to find out.

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 i40 Tourer in the Active grade is great to drive, it’s practical, and should be low-cost to run. But you can bet the new version, due to arrive soon, will be, too. If you can wait, it's a safe bet the new i40 Tourer will have an updated look, improved safety equipment and retain all the good points of the previous model.
