As our rendering suggests, the headlights and grille are connected into a single design unit. Basically all the premium car companies do this now, joined by Kia, Hyundai or Ford. The effect is of a wider, sportier front end, without having to affect the car's proportions.
The current Q7 has headlights that look like they've been styled with christmas decorations. The individual LEDs will be replaced by a Y-shaped daytime running element that flanks the actual Xenon light unit. As an option, Audi will let you order the Q7 with full-LED or Matrix LED.
Underneath the redesigned exterior is the MLB evo platform, which is also said to be going into Bentley's Falcon SUV. It's lighter and stiffer than before. Power will come from some of the most advanced engines on the market, including new diesels fitted with one electric compressor and plug-in petrol hybrids.
There should be at least one SQ7 model, powered by either the V8 from an S8 or the "tri-turbo 3.0 TDI" from the recently revealed RS5 TDI Concept. Considering how the SQ5 is sold with both TFSI and TDI mills depending on the market, we could see both forms of Q7, though not until 2016.
