2021 Audi S8 Summary

Big sedans are not in vogue at the moment and huge luxury sedans were on the way down before the humble Commodore and Falcon departed the upper end of the sales charts. The Germans, who have always done a spectacular job of these flagship sedans, cheerfully persist with these cars.

Absolutely loaded with fascinating technology that bleeds its way down to the more mainstream models, they represent the zenith of the brand's innovation and style. The A8 is certainly that.

What it isn't, is particularly sporty, but after two years since its launch, V8 power has reached the fourth-generation super-sedan to deliver the latest iteration of the iconic S8.

2026 Mercedes-Benz GLE450 Summary

Well into its second generation, the Mercedes-Benz GLE remains a key player in the luxury large SUV space.

Though it lags well behind the BMW X5 in terms of sales, by about half in fact, the GLE still aims to exude status and luxury, helped by a facelift in 2023.

In its category, there are however plenty of badges with the power to lure buyers away: Audi, Porsche and Range Rover. Even non-Euros like Genesis and Lexus.

Despite the facelift, the category is moving on with big screens and more tech, where the GLE still has to rely on some traditional charm to win over wallets - especially in our big diesel ‘450d’ guise.

A week behind the wheel around and out of the city should reveal whether the GLE still has a strong-enough USP in 2025.
