RED BULL RING
I've seen strategies for racing first 18/19 laps in one stint (before rain comes) on FM6 but I ended up 20 seconds too slow for Gold and this strategy might have worked back in April but unlikely now with updates unless particularly lucky with AI. I have just won by what was classified as a lap ahead.
So for what it is worth this is my strategy as of 1.27 ...
In summary :-
RS, FM1, Lap 1-10, Refuel to Max,
RS, FM1, Lap 11-19, Refuel to Max (I pitted on 18 but was probably premature for best result)
W, FM1, Lap 20-26, Refuel to Max (you may get away with 90% if you run to 36 laps but not worth risk)
RS, FM1, Lap 27-37 (had 11% fuel as end of 36 and could have waited for clock to run down, had 4% of fuel a lap later)
Detail/tips :-
Peugeot RCZ Gr.3 - make sure you own Wet and Racings Soft tyres. Put on Racing Soft and go to Red Bull Ring on Time Trial and make sure you can lap in the 1:28 - 1:29s with unrestircted car - mine was PP787.34 with 450/620 wing and High RPM Turbo - no idea how the game reduces your car's PP for the mission so just adding this for context. I used TC1, ABS and all other assist off.
For the mission, start off on RS, FM1 and aim for 1:31 - 1:32 pace. I pitted end of Lap 10 just a whisker under the 45mins remaining with left rear about 80% worn and I was 22 seconds behind leader with 5% fuel left.
Put on a new set of RS and fuelled to max, came out 32 secs behind leader. I came in at end of Lap 18, 12.5 seconds behind leader and 32mins left on clock, 26% fuel. I put on Full Wets and refilled and switched to TC5.
I come out 42 seconds behind leader and start practicing braking off the racing line but I notice that with 30mins left on clock, as I almost complete lap 19 the tyre meter is only just at the Inters level so I daresay I could have pitted and end of Lap 19 for a quicker strategy - I lost 12 seconds on that lap alone being over-cautious and being on wrong tyres.
By end of Lap 20 the tyre metre is into the Wets range and I am giving myself 50m more braking distance and being ultra careful around turns 4, 9 & 10 as these are super slippery. On Lap 21 I pass Beauvois for the Lead, he looks like he has stayed out on the wrong tyres and I am 18 seconds ahead at the end of that lap. This is the trickiest phase of the race - brake off the racing line if you can, don't be in a rush to visit the scenery, keep a cool head, easy on the throttle and brake and don't take risks in 4, 9 & 10 - keep away from kerbs. You should be able to keep the gap fairly steady. On Lap 25 a dry line starts to appear, try keeping to it and braking on racing line again, start decreasing braking distances to normal.
I came in end of Lap 26, 14 seconds ahead, 17 mins on clock, put on RS and fuelled to max. Came out 19 seconds behind leader.
No heroics, keep to racing line where it is dry, uber careful corners 4, 9 & 10 still, part from that flat out as per the first stint but keep off kerbs. On lap 31 I felt brave enough to go back to TC2, had made a few errors by this point and was 26 seconds back. Gallo was showing 1 second behind me but not in mirrors which was odd and nearest car behind me in 3rd was half the longest straight behind.
Lap 33 the Leader (Lopez) pits - he is showing as being on Wets with 32 Litres of fuel, he emerges 7 seconds ahead of me - at this point I thought race was lost as only 4 mins left, but I am catching him ... I get the gap down to 2 seconds by the end of Lap 34 but he pits again!! I notice he was still on Wets so he either didn't do anything in his previous pit or he put on new Wets, either way some bizarre choice. I notice on the replay, he then puts Inters on - there is no water on the track! So he is 20 seconds behind me now and on the wrong tyres. I am still uber careful corners 4, 9 & 10 - that's my key advice.
There was 8 seconds on the clock as I started Lap 37, Lopez was 21 seconds behind so I could have just waited on the line but I went for another lap.
That was my last Mission Golded, the most satisfying as I had my ass kicked yesterday and then read in loads of places that since the update this was impossible and everyone was losing by 20s with few mistakes. I practiced some more Time Trial, decided to do the 3 stop strategy, learnt where I was most vulnerable in the wet to losing time in the gravel and although I made a few small mistakes going off between 9 & 10 a couple of times, I only got 1 time penalty.
