Neil Warnock returned to haunt former charges Sheffield United as he led his QPR side to a thoroughly-deserved 3-0 victory at Bramall Lane.
The Londoners had failed to beat United in their last eight encounters in all competitions, but had an irrefutable advantage within the opening 23 minutes courtesy of three quick-fire goals.
The impressive Hogan Ephraim broke the deadlock in the 11th minute after smartly finishing a one-on-one, before then turning provider for Jamie Mackie to head home.
The result was out of doubt in the 23rd minute when keeper Steve Simonsen hauled down Adel Taarabt, who then stepped up to score the resulting penalty.
While United boss Kevin Blackwell's programme notes had promised a "spirit of renewed hope and anticipation" his side collapsed as QPR started a league campaign with back-to-back wins for the first time in nine years.
