That's the car I wanted to vote for but had to vote strategically, the Audi's cockpit is just too awkward to drive in. Maybe it's just me but in VR it feels like you are sitting in the back seat.
No, it's hard to explain if you haven't tried it. It is literally as if you are sitting inside a life size car. You don't want to change any FOV settings because what you see on VR is what you would see in real life.
My 2 cents worth. Audi = GR2, fast, sticks to the ground well. Nissan = Turns like a boat, some back end twitch. Porsche = Road car, stable, but it's a road car. Everything is slower than a race car. Haven't yet tried the McLaren.
