As the description says, the trophy is unlocked as long as you win a race without activating the KERS or DRS during the race. This can be obtained in any race, regardless of mode. The race can also be any length, including 1 lap. The default controller settings map KERS to
and DRS to
. I would recommend simply avoiding these buttons throughout the race and you should be fine.
This trophy can be made easier if you play with the difficulty set on easy and all driving assists on. Next, go into Grand Prix Mode, start a Short Race weekend with a top tier constructor (Red Bull, McLaren, Ferrari), and qualify for pole position. You will then begin the race in first place. Just avoid hitting the
and
buttons and you should easily win.
