The second Q8 concept - the first was revealed at the Detroit motor show in January - runs a newly developed petrol-electric hybrid driveline that is claimed to endow it with 0-62mph acceleration in 4.7sec along with an overall range of up to 746 miles, in combination with an 85-litre fuel tank and 0.9kWh lithium ion battery pack.
The new Audi is expected to be placed into production in 2018, acting as a range-topping model in the new Q8 line-up. Although officials at Audi’s Ingolstadt headquarters in Germany initially hinted the new SUV would wear RS Q8 badges, it now appears it will be marketed under the SQ8 name.
The Q8 Sport Concept is outwardly distinguished from the earlier Q8 Concept by a series of stylistic upgrades aimed at endowing it with a more sporting appearance than its milder powered sibling. Included is a restyled single frame grille featuring a black frame and honeycomb lattice insert.
The new grille is set within a more heavily structured front bumper housing enlarged air ducts and a more prominent splitter element in the form of a black blade along its lower edge. The headlamps have also been modified with darkened inserts but retain the same distinctive x-shaped LED graphics as the earlier concept to give the new Audi a rather sinister look from front on.
Further back, there are black exterior mirror housings and black sills underneath the doors. Compared to the Q8 Concept revealed at the Detroit motor show in January, the wheel houses have also been widened by a further 12mm.
