2024 Audi RS4 Summary

It's the end of the line for that Audi A4 as we know it. In saying goodbye to the ‘B9’ generation A4 that launched in 2015, we welcome the Audi RS4 Competition Plus. 

It is the most hardcore example of the breed yet, sitting lower to the floor with hard-edged gear changes, lightweight wheels and snuggly bucket seats. You can also get it in swoopy RS5 Sportback guise. 

Audi is only bringing 75 units of each down under as a swan song for the B9 generation RS4 and RS5 before the even-numbered model moves into its all-electric future.

As we’ll go on to discover, these two special models see the A4 and A5 bow out in style.

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.
