My Audi A4 had 7 speed CVT transmission. Why? Because it had paddle shifters, same as Grande. Those are not real gear ratios, they are virtual gears to give a feel of shifting. I have not driven Grande, so don't know how it works. But on A4, virtual/simulated gears only worked when on paddle shifters, otherwise it had constant RPM sound when floored and no feel of shifts.
Oriel does not have paddle shifters, so there is no point creating virtual shifts.
