And another thing, what's the purpose (practical side) of KERS? Meaning, when and why to use it?
Sorry, but it's puzzling me...
In real life, KERS gives a small temporary boost of power when activated. The KERS power lasts for a few seconds, then needs recharging.
In iGP, however, it is a bit different. It's like having a nitrous oxide canister on board or having an afterburner fitted to your car. Unlike real life it cannot be recharged, but when it is activated you get a SIGNIFICANT increase in performance. If you activate the KERS in a DRS zone, you can pass five or more cars in a single straightaway.
In other words, KERS is not only essential, but you probably cannot win a race without it. So when you CAN get it, DO get it.
