It’s hard to believe that the second-generation Audi Q7 is now four years old, which makes it ripe for a midlife update. This partially camouflaged prototype unit was spotted by our spy photographers, and from the looks alone, it’s clear that the SUV is due for a major facelift exercise.

Let’s start from the front. The Q7 looks set to ditch the old Singleframe grille with horizontal slats, in favour of the more rugged chequered unit with thicker surrounds. The lower apron will also feature two air inlets – expect the headlights to be redesigned as well, featuring new LED DRL graphics.

Round the side, the changes, if any, aren’t visible through these photos. The rear end however, looks to get brand new tail lights with multiple diagonal LED bars that guide the eyes to the Audi badge. The lower valance appears to be redesigned as well, and bears greater resemblance to the one seen on the Q8 – right down to the larger trapezoidal exhaust exits.

Beyond that, it remains to be seen if the Q7 will get an overhauled cabin. However, it makes sense to think that the Q7 will get the more modern cabin of the Q8, with dual touchscreen displays in the centre – a 10.1-inch MMI infotainment unit positioned above, and a smaller 8.6-inch panel below for HVAC controls.

Performance-wise, expect the existing range of petrol, diesel and hybrid powertrains to be offered, from a 2.0 litre four-cylinder TFSI petrol to the hot triple-charged 4.0 litre TDI V8 in the SQ7. The latter, combined with a 48-volt electrical system, makes 435 hp and a whopping 900 Nm of torque. That’s enough for a 0-100 km/h time of 4.8 seconds, and it manages 7.4 litres per 100 km (13.5 km/l) in the NEDC.
