Yvan Muller blitzed the first World Touring Car Championship practice on the streets of Macau, finishing nearly three quarters of a second clear of the rest of the field.
The fight for top spot had been a close run affair over the opening 15 minutes, with Muller, Pepe Oriola, Tom Chilton and then Rob Huff all enjoying spells out front as times steadily improved.
Muller ended that dynamic in emphatic style however as he set a 2m31.121s that blew his rivals out of the water.
Oriola twice threatened a response when he ducked under Muller's sector one split, only to lose swathes of time through the intricate middle sector.
He did at least improve marginally to secure second, and finish as the only man to get within 0.75s of the four-time champion.
Huff, who had languished down in 31st before his first flyer moved him to the top of the timesheets, ended the session third.
That put him narrowly ahead of the first works Honda of Tiago Monteiro and Muller's team-mate Tom Chilton, with the trio covered by just over one tenth of a second.
James Thompson put his Lada sixth, just edging out Gabriele Tarquini in the second factory Civic.
Stefano D'Aste finished as top BMW in eighth, but was almost eight tenths of a second down on Tarquini. Marc Basseng and Tom Coronel rounded out the top 10.
As was the case in Thursday's pre-weekend test the session was punctuated by several crashes, the heaviest coming when Ng Kin Veng lost his China Dragon Chevrolet at Police and speared into the barriers.
Campos newboy Konstantins Calko locked up right behind and hit the side of Veng's Cruze, damaging his SEAT - although he then optimistically continued for a further two laps before pitting under the encouragement of the black and orange flags.
Eurico de Jesus later went off at Maternity, but was able to rejoin without damage, while Norbert Michelisz and Tarquini came together at Lisboa with seven minutes to run.
The Zengo Honda man had not set a competitive time at that point, but managed to salvage something from the session by continuing - rear bodywork missing - and moving into 13th at the flag, albeit some 2.7s off the outright pace.
