3:18's are possible.
My qualifying time for the first LMP1 Le Mans race on the day the update released was a high 3:23.
Basically you need to manipulate the KERS system to your advantage. In this game the KERS system is set to "hot-lap" mode which means that it is set so that it automatically deploys upon throttle application reaching a certain percentage instead of needing to be manually deployed by pressing a button. In real life that's basically the setting the teams set these cars to for qualifying whereas for the race they change the setting so that it gets deployed manually and acts more as a "push to pass button"so drivers will save the KERS for when they are in the slip stream of another driver to perform an overtake or they will use it defensively to prevent being overtaken in some situations. Other key things to note:
- KERS is recovered upon braking (in real life the 2017 LMP1 cars also start recovering some KERS on lift-off as you might notice on kobayashi's record lap below) so that means braking for a little bit longer in the big braking zones has it advantages
- KERS is driven through the front wheels, when KERS is not active these cars are rear wheel drive
- Applying half throttle in smaller acceleration zones (such as the short straight between Indianapolis and Arnage) has its advantages as you will then be reserving all of the KERS energy for a longer straight where the amount of time gained by using it will be far greater.
- There is a limit to the amount of KERS that can be used per lap, this varies track by track and is based around the length of the track in question. So you might find that if you've been heavy on KERS use then you will find that it won't be activated anymore from around the half way section on the track
- There is an indicator on the steering wheels (or interior screens) of the cars to show how much KERS you are generating under braking, how much you are using on straights and when it is being activated
I will do a couple of quick laps later today to see at what % of throttle application KERS is activating in this game and how much KERS you are allowed to use per lap (in % form). In the meantime take a look at Kobayashi's lap record from last year and keep an eye on the hybrid (the overall amount of KERS limit left for the lap), throttle and brake bars in the broadcast HUD at the top left:
