The Monster Energy Super Charge Award is awarded to the first driver to reach the first corner in a Supercar Final of an event. You can unlock this while going for the RX World Championship in the Freeplay tab of the main menu, while the most convenient track to get it in is Canada, since the start/finish straight on that track is very long. With the AI difficulty set to "0", you'll reach the corner first every time, as the AI have the usual speed limiter.
The award is now awarded to the driver with the quickest reaction time off the line, not the first one to reach the first corner. Therefore, staying focused on the lights and letting go of the handbrake as fast as possible are of vital importance. Your chances are better if the AI is set to its lowest setting, whereas the track doesn't matter. Some tips:
- Have Automatic Launch Control set to "off". You can beat the other cars off the line by using the handbrake and letting go right before "Go!". The assist lets you go a few tenths after the lights go off, putting you at an obvious disadvantage.
- Have TCS set to "off". The Supercars are AWD anyway and we're talking about reaction time here, so it wouldn't matter either way.
You need to make sure you are in the first row of the starting grid in the Final round of an Event. That's accomplished by doing good in the previous rounds, so make sure the Qualifiers and the Semi-finals go well for you.
If you think you've gotten the fastest start but the achievement still hasn't popped, just pause and restart. In the World RX Championship restarts are infinite, so you can keep going until it unlocks.
