Audi's new flagship Q9 is the largest and most luxurious SUV the brand has ever built.

Audi is gunning for the BMW X7 and Mercedes-Benz GLS with its first-ever Q9 SUV, a vehicle that the Ingolstadt-based manufacturer describes as "unapologetically high status".

That is reflected in both its size and levels of luxury.

At 5.31 metres long, it is a substantial 238mm longer than its Q7 sibling and even outstretches its Bavarian rival by 130mm.

But it is not just size that counts; it is what you do with it. To that end, the Audi Q9 elevates the brand with true business-class features such as individual electric seats in the second row, automatic doors and the largest panoramic sunroof ever fitted to an Audi.
