The second generation Audi Q7 has received a speculative digital interpretation based on recent spy shots.

The second generation Audi Q7 has received a speculative digital interpretation based on recent spy shots.

Last week we saw the all-new Q7 undergoing testing with minimal disguise and now X-Tomi Design decided to show us what's probably hiding underneath the camouflage. Don't expect the Prologue concept's styling to rub off on the second generation Q7 because the full-size SUV's styling was finalized before Marc Lichte took over as Audi's design chief.

Instead, the 2015 Q7 will adopt an evolutionary design creating a significantly less bulky appearance thanks to the sharper and more angular styling. While the SUV's appearance won’t be a major departure compared to today's model, everything else will as the Q7 is going to sit on the MLB Evo platform which will bring an estimated 800 lbs (363 kg) diet while matrix LED headlights will be optionally available.

Today's six- and eight-cylinder engines will be carried over with some updates and there are also talks of a range-topping SQ7 variant with a system sourced from the RS5 TDI concept which came with a supplemental electric turbocharger. Also expect a Q7 e-tron with the hardware borrowed from the Porsche Cayenne S-E Hybrid.

The second generation Audi Q7 is programmed to go on sale in the first half of 2015 and will be followed in 2016 or 2017 by a Q8 model with a body style in the same vein as the BMW X6.
