Michael Frey made one goal and scored the winner in a masterly centre-forward’s display as QPR scored twice in three minutes to come from behind and beat Luton Town.
Frey powered home a beautifully measured volley to earn Rangers their first Championship win of the season, just moments after his brute strength and awareness had teed up Nicolas Madsen to level the scores.
The equaliser had come against the run of play, as was the case with Luton’s first-half opener which was gifted to them when the unfortunate Jimmy Dunne bundled the ball into his own net from close range.
Luton, who remain winless with just one point and two goals from their four league fixtures, barely threatened an equaliser until injury time.
A frantic finish saw Carlton Morris denied by keeper Paul Nardi's fine save and Joe Taylor head over from close range.
But the spirited late rally could not salvage a draw or stop a few boos echoing around Kenilworth Road at the full-time whistle.
Without a victory between them in their opening three league matches, and just three days after QPR edged past Luton on penalties in the EFL Cup, a tentative start seemed likely.
But for 17 minutes, QPR retained possession impressively, seized control of the midfield and looked sharp in attack.
The experienced Jack Colback, back in the side after suspension, was the instigator of much of their best work, with some neat combination play between Madsen, Kenneth Paal and Frey creating several promising situations.
Alfie Lloyd on the left and Karamoko Dembele on the opposite flank both stood out, however, the latter missed a golden chance to make their superiority count, lashing the ball wide of the far post with his weaker right foot after some super build-up play by Frey.
Luton had been surprisingly passive, but the urgency returned after that wake-up call and they led moments after their first attempt on goal forced a corner which was only half-cleared.
Shandon Baptiste crossed the ball back in and although a thumping header by Mark McGuinness was saved by Nardi, the ball rebounded back off Dunne and into the net.
