The Brumbies returned to the top of the Australian Super Rugby conference thanks to a dominant 30-20 win over the Lions at Ellis Park on Saturday.
The Waratahs had taken top spot in the Aussie group with their win over the Sharks earlier in the day but the Brumbies put five vital points in the bank ahead of their bye next weekend.
Unlike last week's ill-tempered battle with the Stormers, the Brumbies put their skills on display rather than looking to turn the game into an arm wrestle and they blew the Lions away.
The Brumbies outscored their hosts by four tries to two as they bounced back from defeat at Newlands last week to move to second in the overall standings.
The result leaves the Lions four points behind the Bulls in third place in the South African conference.
The visitors led 22-6 at the interval thanks to tries from centre Tevita Kuridrani, number eight Ita Vaea and fly-half Christian Lealiifano, who all scored in a blistering eight-minute spell in the middle of the first half.
Lions flanker Jaco Kriel pulled a try back around the hour mark but the Brumbies secured the win and the bonus point when wing Joe Tomane raced home, making the home side's full-back Andries Coetzee's late try prove to be nothing more than a consolation score.
Elton Jantjies opened the scoring for the Lions from the kicking tee, and when Ruan Combrinck landed a 60m penalty, the Lions were looking good at 6-0 early on.
But the hosts would have to wait 50 minutes before they scored again as the Brumbies took the game by the scruff of the neck.
Kuiridrani ran onto a flat pass from the excellent Nic White for the game's first try in the corner before Vaea powered over from close range just three minutes later, with White again providing the final pass.
Leali'ifano then intercepted a shocking long pass from Robbie Coetzee to sprint home untouched. The Wallaby back added his second conversion, meaning the Brumbies had scored 22 points in 10 minutes.
The Lions buckled down to keep their free-running visitors at bay until half-time and Kriel gave them a glimmer of hope when he burst through a ruck and charged over the line as the game entered the final quarter.
The Brumbies weren't to be denied though as White and Jesse Mogg combined to put Tomane clear for the bonus-point try after a strong scrum.
Mogg then rubbed salt into the Lions' wounds with a 55m penalty with the result wrapped up, before Coetzee produced a fine finish for a late try for the Lions, but the game had long been lost.
