Sehwag scored 87 off a mere 48 balls as Delhi extracted a sweet revenge of their defeat at the hands of the same opposition three days back.
Delhi's domination was evident by the fact that they won the match with as many as four overs to spare.
And leading the charge was Sehwag whose innings was studded with 10 fours and three six.
Sehwag added 89 runs for the second wicket with Kevin Pietersen (27 off 21) in just 8.2 overs, and that paved the way for the convincing victory.
Earlier, despite a few drop catches, the Daredevils rode on a disciplined bowling effort to restrict the Warriors to a modest 146 for two.
When the visitors turn to bat came, Mahela Jayawardene initially went for his shots, while Sehwag was happy to play the second fiddle, but after the Sri Lankan was run out for a 14-ball 18, the latter started to free his arms.
After sending the ball twice to the fence in one of Ashish Nehra's overs, Sehwag hit Luke Wright, who replaced Angelo Mathews for this game, for a four and a six off consecutive balls.
Pietersen joined the party and the duo smashed the Pune bowlers at will to take the team past the 100-mark in the 11th over.
Rahul Sharma gave the hosts a breakthrough by sending back Pietersen, but by then the damage had been done.
It was just a matter of time before Sehwag and Ross Taylor took the Daredevils home.
