A few comments from the above posts in no particular order of importance:
Gas is premium 91 octane not regular.
Tires if 20 inch for the S are All Season not summer tires. The reason you say not suitable in the winter is because in the province of Quebec, you must have winter rated tires by law. Obviously winter rated tires are better in the winter/snow/ice but according to some on this forum, notably Trek, not necessary. I do not agree with Trek on this one. Even in Toronto where we get very little heavy snow falls and some winters the grass is bare, I put on winter tires. My tires are Pirelli Winter & Ice which is a lighter tread, not great for heavy snow but better than the all seasons but very good on ice and slush. Very quiet running tires cannot tell the difference from my OEM All Seasons. My theory is that it is the one snowstorm or ice storm that I will not be close to home or driving in rush hour traffic up a hill or a down a hill (Toronto has hills) that the winter tires will save me from an accident. Also with two sets of tires all season and winter I will not have to buy replacement tires for the time I own the vehicle which usually is about 4 to 5 years at about 12000 kilometers or 7500 miles per year.
As for the make of OEM tire if you have 20 inch tires only one tire is sourced by Jaguar for this vehicle, made by Goodyear especially for the F Pace.
"Eagle F1 AT. They are M&S 255/50 R20 109W. Definitely built for Jaguar, as they actually have "JLR" on the sidewall." Quote comes from ddrsport june 29 2016 post on this forum.
As for the F Pace being better on snow, likely the condition, the make and model of the tire is a significant factor. Put on the same tires in the same condition to truly compare. Also the tires on the Audi are wider, they will have less traction in the snow.
The comment about full time all wheel drive vs part time drive is not valid. Part time is actually very sophisticated. Adjustments to the torque and power going to each wheel is being constantly adjusted in microseconds by the onboard computer, if it detects slippage in one wheel or the other, to get the vehicle back on track. Full time all wheel drive can have the same system but what is the point of driving all four wheels on flat dry pavement other than wasting fuel.
