Audi S8 vs Volkswagen Touareg

What's the difference?

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.

It’s big, it’s fast, it’s luxurious, Volkswagen’s Touareg has always been a stand-out large SUV.

This one, the full-fat R is the latest take on the halo Volkswagen model. It has big shoes to fill.

See, top-spec Touaregs in the past are hardly rivals to the Toyota LandCruisers and Hyundai Palisades of this world. They’re a different breed, with the first-generation Touareg powered by a variety of engines up to a 5.0-litre turbo-diesel V10, and the second-gen version packing petrol and diesel V8s in its upper levels.

They were the ultimate sleeper family SUV, ridiculous engines with rich VW Group lineage in a seemingly mainstream family-friendly package.

But this third-generation version can’t quite replicate the over-engined craziness of its predecessors. It has to think outside the box as emissions regulations crack down the world over.

This Touareg R is a plug-in hybrid. A performance-focused one at that. Can it hope to replicate the unhinged nature of its forebears and find an appropriate place atop the hierarchy of Volkswagen’s R models? Let’s find out.
