Knight Riders shot out a lacklustre Delhi for 98 before cantering home in 14.1 overs with openers skipper Gautam Gambhir (38 not out) and Robin Uthappa (35) sharing a brisk 69-run stand.
Andre Russell (3/24) and 45-year-old Brad Hogg (3/19) were the star bowlers for the home team after Gambhir put the opposition in.
While the two-time champions made an ideal start to the season, a fresh squad, mentored by Rahul Dravid, did not change the fortunes of Delhi who finished seventh out of eight teams in 2015.
Gambhir and Uthappa made batting look easy during the chase as the team completed a convincing win. Gambhir was solid in his 41-ball knock, collecting five fours while Uthappa smashed seven boundaries including a couple of delightful straight drives.
