Audi has released the official sketches of its brand-new concept model – the Audi Q8 – ahead of its official debut at the upcoming North American International Auto Show (NAIAS) in Detroit in January 2017. The 'near-production' model will be the new flagship of Audi's Q range of SUVs and will sit alongside the flagship A8 sedan. The production-intent Q8 is expected to hit the market in 2018, and will compete with the likes of the BMW X6, Mercedes-Benz GLE and others.
