F125 ERS modes explained

Learn about F125 ERS modes explained


Updated October 3, 2025

Quick Answer

ERS in F1 25 is simple: you have automatic energy harvesting and one manual deployment mode called Overtake. Bind a button to ERS Overtake, turn the assist off if you want manual control, and use Overtake on straights for attacking or defending. Protect your battery (20–70% state-of-charge) so you always have power when it matters.

Why F125 ERS modes explained Feels So Hard at First

You press buttons and the car sometimes flies, sometimes fades, and the battery bar seems to melt away. That’s normal. F1 25 simplified ERS into an easy system, but timing is everything: deploy too early or too often and you’ll run flat when you need it most. By the end of this guide, you’ll know exactly what ERS is doing, how to map the right controls, when to press Overtake, and how to keep the battery healthy over a lap and a race.

What F125 ERS modes explained Actually Means in F1 25

Here’s the truth about ERS in F1 25 (latest patch):

  • The system harvests energy automatically when you brake and when you’re off-throttle. No manual “harvest mode.”
  • You have one manual deployment mode: ERS Overtake. Think of it as push-to-pass.
  • “ERS modes” in this game are effectively:
    • Standard (Off): normal, automatic deployment/harvest.
    • Overtake (On): extra electrical power; drains the battery quickly.
    • Optional: ERS Assist (On/Off): if On, the game decides when to deploy, and you can’t control Overtake manually.
  • Limits you should know:
    • The battery has a finite capacity (shown as a percentage bar on the HUD).
    • Overtake gives a noticeable power boost, especially with DRS, but it burns through charge rapidly.
  • Where to look on-screen:
    • A battery icon/bar with percentage (state-of-charge).
    • An “Overtake” indicator lights up when it’s active.
    • You’ll see speed/RPM surge when Overtake is on.

Before You Start (Prerequisites)

  • Hardware:
    • Controller or wheel with at least one easily reachable button for ERS Overtake.
  • Game version/modes:
    • F1 25, any on-track mode (Time Trial, Grand Prix, Career/My Team, Multiplayer).
  • Menus you’ll use:
    • Settings > Assists (to toggle ERS Assist).
    • Settings > Controls > [Your Device] > Edit Bindings (to bind ERS Overtake).
    • The in-race MFD (Multi-Function Display) for ERS status and toggling if you prefer UI control.

Step-by-Step: How to Fix / Improve F125 ERS modes explained

  1. Turn off ERS Assist (if you want manual control)
  • Open Settings > Assists.
  • Set ERS Assist to Off.
  • Success check: You can now toggle Overtake yourself; the game won’t deploy it for you.
  1. Bind an easy ERS Overtake button
  • Go to Settings > Controls > [Your Device] > Edit Bindings.
  • Find ERS Overtake or ERS Deploy and assign a convenient button (thumb button or wheel paddle).
  • If available, prefer a Toggle binding so you don’t need to hold it down.
  • Success check: On track, pressing the button shows “Overtake” activated on the HUD.
  1. Learn the HUD and battery behavior
  • Drive a few corners without pressing Overtake. Watch the battery % rise under braking.
  • Press Overtake on a straight. Notice the stronger acceleration and the battery bar dropping faster.
  • Success check: You can predict battery drop when deploying and see it recharge when you brake/off-throttle.
  1. Use Overtake where it matters
  • Best places:
    • Exits of slow/medium corners onto long straights.
    • With DRS open to maximize top speed.
    • To defend when a car behind has DRS.
  • Avoid:
    • Mid-corner or in heavy wheelspin (you’ll waste power).
    • Very short straights where you’ll have to lift or brake immediately.
  • Success check: Your top speed improves on main straights and you can attack/defend more effectively.
  1. Manage the battery across a lap
  • Aim to finish a lap with 20–50% battery remaining in races; 40–70% in qualifying prep.
  • Recharge opportunities:
    • Lift slightly before braking zones.
    • Don’t spam Overtake every single straight; pick your battles.
    • Under Safety Car/VSC, don’t deploy—let it recharge.
  • Success check: You rarely run under 10% unless pushing for a pass, and you can always respond to threats.
  1. Qualifying routine (simple and effective)
  • Out lap: No Overtake. Build temperature and recharge.
  • Push lap: Use Overtake out of the slowest corners onto the longest straights; save some battery for the final sector’s main straight.
  • Cooldown lap: No Overtake; recharge fully.
  • Success check: Full battery at start of push lap and strong sector-end speed where it counts.
  1. Race routine (attacking/defending)
  • Early laps: Be conservative; stay above ~30% so you can attack or defend with DRS trains forming.
  • Breaking DRS: Use Overtake on key straights to get over 1s gap; then recharge one lap.
  • Defending: Toggle Overtake only when the car behind is within attack range on a straight.
  • Success check: You keep a “reserve” always ready and avoid getting stuck powerless in DRS zones.

Common Mistakes and Myths About F125 ERS modes explained

  • “There are many ERS modes to cycle.” Not in F1 25. It’s Standard or Overtake (plus the optional Assist).
  • Spamming Overtake everywhere. You’ll drain the battery and be a sitting duck later.
  • Deploying too early on corner exit. Wait until wheelspin is controlled and the car is straight.
  • Using Overtake mid-corner. It adds power when you least need it and can cause understeer or wheelspin.
  • Forgetting ERS Assist is On. The game may deploy at the wrong times for your strategy.
  • Confusing ERS with fuel mix. Fuel mix is locked; ERS is your main power tool.

Troubleshooting and “What If It Still Feels Wrong?”

  • Battery never seems to recharge

    • Likely cause: You’re constantly deploying and not giving the car braking/off-throttle time.
    • Fix: Do 1–2 laps with minimal Overtake, brake firmly, and lift a touch before big stops to harvest more.

  • Overtake does nothing in the wet or low grip

    • Likely cause: Wheelspin or traction control kicking in wastes ERS.
    • Fix: Deploy later on the straight, after the car is straight and stable; be gentler on throttle.

  • Can’t manually toggle Overtake

    • Likely cause: ERS Assist is On or the binding didn’t save.
    • Fix: Set ERS Assist = Off; rebind ERS Overtake; test in a practice session.
    • Note: If your changes don’t apply, make sure you confirmed/saved the control profile before leaving the menu.

  • Battery drains super fast in DRS trains

    • Likely cause: You’re matching others’ deployment every straight.
    • Fix: Choose your moment. Save for 1 lap, then use a big burst with DRS to pass; recharge after.

  • Career mode: ERS feels weak late in a season

    • Likely cause: Power Unit wear (MGU-K/ES) reduces effectiveness.
    • Fix: In Career/My Team, open Car Management > Power Unit and fit fresher MGU-K/ES before quali/race.

  • Multiplayer: Everyone rockets past me

    • Likely cause: You’re using Overtake in the wrong places or too early.
    • Fix: Deploy only on the longest straights, starting after the apex when traction is solid; keep 20–30% in reserve.

  • Don’t do this:

    • Don’t leave Overtake on for entire laps—you’ll empty the battery.
    • Don’t bind Overtake to a hard-to-reach button; you won’t use it properly.
    • Don’t rely on ERS to fix poor exits; focus on clean traction first, then deploy.

Pro Tips Once You’re Comfortable

  • Pair DRS + Overtake: The combo gives the best top-speed gain for the least battery.
  • Time your press: Activate Overtake just as you unwind steering and cross ~4th gear/up; earlier if grip allows.
  • Energy budgeting: On high-ERS tracks, target a simple rhythm—deploy on two main straights, skip the rest, recharge in twisty sectors.
  • Pit strategy: Save ERS before a pit stop; push hard on the out-lap with warm tires to secure track position.
  • Formation/SC laps: Never deploy; maximize recharge for the restart burst.

How to Know It’s Working (Definition of Done)

Run a 5-lap practice at Austria or Monza and check:

  • You can toggle Overtake reliably and see the HUD reflect it.
  • You deploy mainly on the two longest straights and finish each lap above 20–30% battery.
  • Your top speed is clearly higher with Overtake, especially with DRS.
  • You can save for one lap, then pass using a strong, well-timed burst.

If you can do all that, you’ve got F125 ERS modes explained nailed.

  • Now that your F125 ERS modes explained is dialed in, the next big gain usually comes from braking consistency. Read our guide on F125 braking technique.
  • Want better exits so ERS hits harder? See F125 traction and throttle control.
  • For clean, fast laps with less battery waste, check F125 racing line and corner exits.

Step-by-Step: How to Fix / Use / Improve F125 ERS modes explained

(Quick recap for scannability)

  1. Settings > Assists > ERS Assist = Off (for manual control).
  2. Settings > Controls > Bind ERS Overtake to an easy button (toggle preferred).
  3. Practice: No Overtake in corners; deploy on main straights once the car is straight.
  4. Keep 20–70% battery; save on one lap, spend on the next for overtakes/defense.
  5. Pair with DRS for maximum effect; recharge under braking and off-throttle.

You’ve got this—small, smart deployments beat constant spamming every time.
