Been asking for this for years, I sincerely hope F1 2018 finally has proper ERS simulation. Why? Because its realistic, and adds immersion, and crucially, is a major part of a drivers toolkit in terms of attack and defense this year. The cars make nearly 1000 hp, but can't always have that much power as we do in the game. In races, they have maybe 800-850 in general, based on the ERS settings. They manage and deploy, and its not as simple as just having all the power whenever you floor it. Now, the real life F1 has an insanely intense and complicated system for this, as modeled in Assetto Corsa (I think?), but we can have a far simpler setup, that will definitely make it more exciting.
Simply put, the ERS should be a STRAT 1-STRAT 5 option set. And they work and are used as described.STRAT 1 (High Recovery)
- High recovery mode, you'd use when you are managing a gap. Battery level charges by maybe 15-20% a lap (based on quality of ERS, can be developed in career mode). Derates quite aggressively, maybe 150-200 meters before braking zone (again based on ERS quality). Have about 10% less power overall compared to STRAT 3.STRAT 2 (Mild Recovery)
- Mid level recovery mode. Again, you'd use this when managing a gap, though can't afford to give away as much lap time as STRAT 1 would. Battery charges by maybe 5-10% a lap. Moderate derates. 100-150 meters before braking zone. Have 5% less power than STRAT 3.
STRAT 3 (Neither boost nor recovery) - Default mode. Those who don't want to bother can just leave it in STRAT 3 and be fine. Doesn't charge or discharge battery. Derates 50-100 meters before braking zone.
STRAT 4 (Mild Boost) - Mid level boost. When you are pushing, but not yet close enough to make an overtake. Battery discharges by 5-10% a lap. Overall HP about 5% more than STRAT 3. Derates 25-50 meters before braking zone.
STRAT 5 (High Boost) - What you use for overtaking, an outlap/inlap and the race start. Max battery power. Discharges battery by 15-20% a lap. HP about 10% more than STRAT 3. No derates.
Now, if any of these modes result in you using up all the battery, it will automatically go to STRAT 1 and be locked until you get to at least 25% charge. If you hit 100%, it will automatically go to STRAT 3 if you aren't already there. There will be an Overtake button which will activate STRAT 5, either while it is depressed, or until you brake.
This is about as simple as you can make the system. I know real ERS uses braking and stuff but thats too complex. A simple 5 mode system is perfect for the level of complexity of this game.
