KERS and DRS Guide

Discussion in 'F1 2011 - The Game' started by Kyle Dunning, Oct 5, 2011.

  1. So you picked up this game just recently, and you played F1 2010 to death? But now you got F1 2011, and we have new toys to play with in this game.

    KERS (Kinectic Energy Recovery System) is a boost to your acceleration, you get to choose when and where you use KERS, and you get a certain amount of boost every lap, this gets recharged back to full as you cross the start/finish line.

    DRS (Drag Reduction System) is a great boost to your acceleration, it is basically the rear wing moving to allow air to flow more aerodynamically so the car gets less drag, however it makes the car unstable on corners.

    When I first played this game, they were both difficult to integrate into my racing, I had become used to simply driving around the track, now I had to use these new boosts to make sure my laps are decent.

    So you may be thinking, when do I use KERS and DRS? Do I use them together? Do I use my full KERS on one straight? Can I use KERS around a corner? Is there any corners I could use DRS without the car spinning out?

    This is what this guide is about, but before you take anything posted here to heart, this is a guide, from my own personal experience, KERS and DRS is likely to be used in different places from player to player, and even from lap to lap.
    I have played around with KERS and DRS a lot, experimenting on when it should be used, and learning when it really is not suitable.

    How to use KERS

    It depends on what track you race on, it depends on whether your in a race, or doing a Time trial, the key is to notice when it is right for you, and where you can find the maximum potential from lap to lap.
    After you have got into a nice routine, you will find that deploying the KERS becomes second nature.

    Time trial

    Start of a lap - You should use as much KERS possible before you cross the Start/Finish line, as this will give you a great deal of acceleration to begin your lap, and your KERS will automatically become recharged anyway.

    This is where you may be thinking, some tracks (Silverstone, Nurburging) have the start/finish line close to the last corner, therefore it is never possible to use the full charge, unlike places like Monza where it is really easy to achieve that.

    So you may be thinking, could I use it while turning through the corner? My answer is definitely Yes.

    But the problem about doing this, you need to make sure that when you deploy KERS, that you are already halfway through the corner, and accelerating out of it, this will give you the best launch into the straight and you will be using the maximum amount of KERS available.

    End of a lap - Some players, would say to save a bit of KERS until you reach the end of your flying lap, but in my opinion it solely depends on the track.

    Just like I said about using the maximum of your KERS, it should be used on the longest straights, on tracks like Silverstone and the Nurburgring, using your KERS at the end of the lap in my eyes is detrimental, as you could have used the KERS on the longest straights, which would help you to get to the rev limiter on gear 7.

    You may be thinking, I have no more KERS to begin another lap??
    This is Time trial, and every split second counts, therefore once you have completed the lap you can restart and you have the full KERS charge again.
    Saving your KERS just so you can go again and do another lap, pretty much defeats the point as you will lose time.

    But if you are on a track, like Monza, or Kuala Lumpur, where the longest straight has its start/finish line a good distance from the last corner, you should definitely save some KERS for it, these tracks are easier to do continuous laps on.

    Using the DRS

    DRS in Time Trial
    - In this mode, you can use DRS at anytime on any straight, DRS should become second nature to you, as you deploy it as soon as your on a straight and the car is stable.

    However, DRS can be exploited, it all depends if you use the suspension bug (11 on both springs), if this is the case, you will be able to use DRS on certain corners which normally would be a bad idea, like the Monaco Tunnel or Eau Rouge in Spa, however the car can still spin out if you turn the car too quickly.

    Usually DRS would close by itself as you brake for a corner, but what about those corners which are full throttle?
    There are a number of corners which are impossible to take with DRS, whether you use the bug or not, sometimes you may forget to turn it off before turning and find the car going into a spin.

    These corners normally come after a short straight, where DRS is not given enough time to give a big advantage.
    It is usually drivers preference, whether they want that short amount of acceleration, at the risk of a possibly unstable car going into the next full throttle corner.

    It is also a matter of how you would disable the DRS, sometimes I would tap the brake gently, instead of using the actual DRS button, so my concentration remains on the cornering and the acceleration.

    These small things can make the difference between 1/10th and a full second, realizing when to use it, and when to close it.

    Have you noticed sometimes, when you try to turn with DRS on certain corners (like the one in Monza after the first chicane for example), the car will actually begin to drift?
    This is when DRS is used incorrectly, as you will lose out on acceleration rather then gain it.

    KERS and DRS - Whenever you can, on every track, you should be using KERS and DRS at the same time down the straights, but the most KERS should be saved for the longest straight.

    You will need to change your gear 7 so that you just reach the rev limiter at the end of the straight(The blue lights above your speedometer).
    If you do not reach the rev limiter, and you only managing to get the green and red lights, then your gear 7 is set too high, and you are losing out on extra acceleration.

    Race Strategy

    As Qualifying and Practice sessions allow DRS anywhere on the track, you should use some of the same methods from Time Trial.

    Qualifying has a slightly different approach, you have a certain lap or two to get the perfect lap, so you should do an easy lap, where you save the majority of your KERS, so you can maximize the acceleration going into the Start/Finish straight to begin your lap.

    Race strategy is pretty different to Time trial/Practice/Qualifying sessions, as DRS is not allowed anywhere, therefore you rely on KERS a lot more.

    DRS Rules

    The usage of DRS is limited by the F1 rules. It is allowed to be used only when:


    • The following car is a maximum of one second behind the leading car.
    • The following car is in an overtaking zone as defined by the FIA before the race.
    Further:

    • The system may not be activated on the first two laps.
    • The system cannot be used until two laps have passed after a restart or safety car appearance.
    • The system may not be enabled if racing conditions deemed dangerous by the race director, such as rain.
    There are lines on the track to show the area where the one-second proximity is being detected and a line on the track where the drivers whose system is deemed valid to be armed may deploy it.

    You may use DRS behind a lapped car, and you are allowed to keep the wing open after passing the lapped car.

    Using KERS at the start of a race

    You may think about how to use KERS at the start of a race, I would say it is all about grid position on how much you should be using.

    Whenever I have started a race at the front, I shall use at least 50% of my KERS to launch myself, it gives a great deal of acceleration and should help for you to avoid close contact into the first corner.
    This tactic could also be used if you are slightly further back, probably in the top 5 or 6 cars, however you really need to make sure that other cars do not get in the way, or you will have wasted your KERS.

    But what if you are further back? What if your in the middle of the pack or right at the back of the grid?
    The chances are you are going to run into trouble, as you will be accelerating much quicker then those in front, and find no real way through, you should be saving most of your KERS.
    You should be more focused on surviving the first corner(if you have damages on) and getting yourself into a good position, then you can use the KERS on the rest of the lap, and this shall help you to overtake a number of cars on the first lap.

    Using DRS and KERS in the Race

    This gives you a great chance to overtake the car in front, combine the DRS with KERS, stay within the drag of the car in front, and you shall receive a huge speed boost, giving you the chance of a pass.
    You will need to brake earlier then usual to make sure you do not run wide, and ultimately lose the advantage you received.

    But what if your out in front, or no where near any cars? You still need to be using your KERS.
    You are much more reliant on this to provide speed for the straights, so save the majority of it for the main straights, and do not waste it on other parts of the track.

    You may think, do I use KERS as soon as I come out of the corner? Or do I wait til further down the road?

    The answer to this, is that on the majority of straights, you should be using KERS as soon as the car is straight after coming out of the straight, so you can reach gear 7 as soon as possible, however this is not always the best way.

    Which gear to begin using KERS?

    After reading peoples responses, I thought about this, and from my experiences, it solely depends on the straight.
    However, I would use KERS as early as gear 2, most of the time in gear 3, but even sometimes I could be on gear 5 or 6 before using it.

    Lets take these examples:

    Track - Description - Gear to begin using KERS
    Spa - Heading up to Eau Rouge, make it clean through there, and use 50% of KERS up the Kemmel Straight - Gear 6
    New Delhi - After the tight uphill turn 3, you get the car straight, I would use 75-100% of KERS here. - Gear 2-3
    Valencia - Over the bridge, turn right on the tight corner, you curve to the left and enter the straight, 50% KERS here - Gear 4-5

    The best example I can see where you should not be using KERS right away, which I found odd but it happened to me, is in Sao Paulo.

    When you come off the last corner and you head up the hill towards the curving left corner, I have found that saving the KERS is best, because if you use it too early, gear 7 will get stuck and you will not get near the rev limiter.
    However if you save it until the car is past the bend, and is just passing the entrance to the pit lane, you will find getting into the rev limiter a lot easier, which will give you a good end to the lap, and a good start to your next one.

    Using KERS as a defense?


    You know the feeling, your being chased, the guy behind you is pretty fast, and you know it may be difficult to keep them at bay.
    Somebody said that using KERS to defend is actually detrimental, as it makes the car behind you even quicker.
    With all due respect, I disagree with this theory, let me explain why.

    -Car 1 is going down the straight, he deploys no KERS, Car 2 is less then a second behind, in the slipstream of Car 1.
    It is clear that Car 2 is going to be really fast, and is more likely to get alongside Car 1 to attempt an overtaking move in the braking zone.

    Regardless of using KERS or not, the car behind will get extra speed using slipstream, so the logic that I see, would you not want to keep your pace up by using KERS, to make it more difficult?
    Even if the car behind does gain a bit of extra speed due to your KERS, your car is also gaining extra speed because of the KERS, so this concept is nullified.

    -Car 1 is going down the straight, Car 2 is behind by less then a second, in the slipstream of Car 1.
    Car 2 uses 50% of their KERS, however at the same time, Car 1 uses 100% of their KERS, so although Car 2 has the slipstream, Car 1 has a much greater acceleration, thus making it harder for Car 2 to get alongside Car 1 for the overtake.

    This leaves Car 1 vulnerable for the rest of the lap, as Car 2 now has 50% of KERS left, but Car 1 was able to hold position, and other parts of the track may be harder to overtake on, so Car 2 might have to wait another lap to try again.

    The best example I have seen of this, is in a real F1 race.
    The Schumacher and Hamilton fight in Monza, Schumacher used his KERS and the Mercedes straight line speed, to keep Hamilton behind him.
    Although Hamilton had KERS, DRS, and the slipstream, Schumacher used his KERS wisely and made it difficult for him lap after lap.

    Saving KERS for Gear 7

    Some players may disagree on the way that I use KERS, I have had a message from a racer who told me it is best to save KERS for gear 7, however I was always under the impression that KERS is used for extra acceleration, and using the combination of KERS and DRS on time trial, you really notice the boost compared to when you only use DRS.

    However I shall try this theory as and when it is possible, which is probably next week, he says that KERS is not beneficial enough to the acceleration, and he only uses it (gives an example of Monaco) up the hill, and through the tunnel.

    One thing I see wrong about doing this, is that when you reach gear 7, you may already be close to the end of the straight, therefore it could be too late to use the KERS up, but I guess that may be pretty situational.

    If anyone wishes to know when and where I use my KERS and DRS on any mode, feel free to ask, I would post it all here but it would make this post a lot bigger then it already is [​IMG]

    I hope this helps someone out there, thanks for reading.

  2. Thanks !!!! very useful ! :)
     
  3. Nice write up.

    I would say the best use for KERs in TT is as you describe, however, you are in a situation were you are doing 1 flying lap then a 'steady lap' conserving KERs for the Start/finish line, then back onto a flying lap again. For me this would seem the best way to exploit KERs to the full. Unfortunatly it is not a viable tactic for qualy as you have to carry too much fuel to make it worth while.
     
  4. Nice job writing up these key elements. One correction on your DRS description - you say, "allow air to flow more aerodynamically so the car gets more drag" and it should be "less drag", not more.

    I heard or read somewhere that KERS was more beneficial after you reach third gear on the long straights, rather than using it directly after a corner. Personally haven't played around with it enough since I'm starting out in the Lotus.
     
  5. Not sure what to do with gearing. For tracks with long straights, KERS, DRS, and slipstream adds up to insane speed. Especially if the car in front is also using KERS and DRS which they usually do. Then I hit the rev limit way before I can make the pass and just stops accelerating. If I adjust the gearing for that situation, then my 7th gear ratio is way too low for normal circumstances such as when I'm leading.
     
  6. I gear my car so that my flying laps with KERS (no DRS) are just below the rev limiter, then make it one notch higher. I use the same ratio in qually as race (those are the FIA rules) so I do suffer a bit in qually. 100% race though means the race matters more.

    There's a line before the DRS activation point for the race which determines the 1s gap (usually the braking zone on the corner before). It's not the same as the activation point. It's often worth using KERS to bring yourself within the DRS zone. Might be worth mentioning this.
     
  7. Nice guide. One thing I usually think about is to not use KERS right in the beginning of a long acceleration. Like say the hairpin in Abu Dhabi. Usually you take that corner in 1st gear. So if you press your KERS as soon as you get out of it, you will most likely end up with lots of wheelspin. I usually start pressing my KERS-button when I go into 3rd.

    That's what I do atleast, maybe some people are really skilled short-shifters, but to minimize wheelspin, KERS on 1st gear is a bad idea :p

    FAQ'd. Thanks Kyle, good job!
     
  9. Maybe also a nice add, is to mention that the best time to use KERS, is when you can go full throttle. If you can't, and you use KERS, you are just using KERS when you can't get full power on the road, and don't have the advantage of the extra power. This also means you can use less KERS in the time it will be effective.
     
  10. YouTube a vettel pole lap onboard and see exactly where to use kers.
     
  11. Yeah - youtube does give some insights into KERS usage. With TCS I tend to deploy it in second gear out of the corners.
     
  12. Ok now this is an FAQ guide, I have updated it and made it a lot more readable.
    Also I added a couple of more pointers in there, after taking feedback from people replying here.

    I am thinking about adding approximate usage of KERS on each track, and on which straights to maximize the use of it, but it would require I get a good amount of time on the game, which may not happen until next week now.

    Also while I am here, I have been asked by a few people for an Australia setup, it is the only one which I did not make.
    I will try and make a setup for that soon as possible, seen as people appreciate my setups that much, also I am unhappy with my current time trial lap on there.

    I have also been thinking about running a RD league, however as the game currently has the suspension bug, and patches are inevitable, I think it is best to wait until Codemasters has finished with those, before starting any up.
    In the past I ran a f1 2010 racing championship, we did all the races, all of them 100% racing distance, ranging from March to September, which I won in Monza, it was really fun for me, and I would like to do it again with F1 2011.

    When the time comes, I shall ask James Chant about setting up my own league. :)
     
  13. One thing I'd like to say about KERS during race is that if you're towing somebody, reserve it until he makes a move. If you use KERS while someone's in your slipstream, it'll only make him go faster.
     
  14. Will good if you post, "How to use KERS on Starts of the Race"
     
  15. Yes, using DRS on cars lapping you is possible, done it plenty of times in my career mode with ****ty Lotus.
     
  16. Thanks mate .. will definately help me !
     
  17. Updates to the guide.

    -Underlined the rule stating that lapped cars CAN be used to open DRS.
    -Changed the Delhi description to turn 3, D'oh on my part.
    -Added a new section, Saving KERS for gear 7, after receiving a message from a player disagreeing with the use of KERS too early.
    -Added a new section, Using KERS at the start of a race, after David asked for it.
    -Added a new section, Using KERS as a defense? After taz104 reminded me of it.
     
  18. kers gives less at high speed... Cause you are fighting drag and resistance and the energy required to accelerate a car from 315 to 320 kph is a lot bigger than from 100 to 105 right. I mean, that's basic physics right? So use it when you are slow, but have full traction and full throttle. A corner is ok as long you know you aren't going to lose the rear. 2nd, 3rd and 4th gears are best. 5 ok. Wouldn't bother with 7.
     
  19. That is what I was thinking Jace, however I want to test this theory out at some point.

    Maybe the game does not follow basic physics. :p
