Recently, mainly due to GT4/GT5 nostalgia, I've played some rather long single-player races. I tried to imitate those grueling endurance races of the past and I've noticed something: tyres and fuel last for ungodly amounts of time/distance in GT Sport. The races so far: · Willow Springs 500km with Gr.4 cars = it was a one-stop race for me even though I was always with the richest fuel mix, AI drivers needed 2 stops. · Blue Moon Speedway 400 miles (200 laps) with Gr.1 cars = another one-stop race for me, I'm sure I could've done it without changing tyres. Most AI drivers needed 2 stops, some needed 3. Easy data: · Gr.4 cars on a flowing roadcourse = 250km per fuel tank, I changed tyres but I think it would've been possible to stay on the same set (although I might've lost more time). · Gr.1 cars on a superspeedway = 320km per fuel tank, tyre change was entirely unnecessary. For example, in GT5's Indy 500 LMP1 race, the fuel tank lasted around 60 laps (150 miles), maybe less for some cars. It feels weird how stupidly fuel-efficient all cars are and how extremely durable the tyres are. Spoiler: PS #1: I won both races. Gr.4's race was somewhat easy and I ended up cruising for most of the 2nd half while the oval race was a lot tougher, asking me to lap very consistently while doing some lift-and-coast before T1 to win on fuel mileage (my original efficiency looked like 98 laps and I needed 100). Spoiler: PS #2: If someone wants to recreate a GT4/GT5 endurance event online in GT Sport, sign me up. I'm not that fast of a driver but I can go around in circles at a somewhat consistent pace.
