Augusto Farfus set the pace in the first World Touring Car Championship practice session at Okayama in Japan
The Brazilian's 1m38.085s lap came 11 minutes into the half-hour session and was enough to keep his RBM BMW on top for the remainder.
Prior to Farfus going quickest, Scandinavian Touring Car champion Robert Dahlgren had led proceedings in his Polestar Volvo.
Dahlgren, who was the first man to set a time on the track, which had dried out considerably since overnight rain, wound up second quickest courtesy of that early lap, 0.520 seconds down on Farfus.
Alain Menu was the best of the Chevrolet drivers in third ahead of his team-mate Rob Huff - who did not venture out on track until there were just eight minutes left - and Norbert Michelisz's Zengo-Dension SEAT.
Championship leader Yvan Muller was seventh in his Chevrolet ahead of the main title rival Andy Priaulx (RBM BMW) and Tiago Monteiro, in the best of the SR-Sport SEATs.
Series returnee Colin Turkington was ninth, 0.8s off the pace in his WSR BMW. Tom Coronel (SR-Sport SEAT) completed the top 10.
World champion Gabriele Tarquini was 11th for SR-Sport while the Poulsen Motorsport BMW of Kristian Poulsen was the best of the independent entrants in 12th.
Macanese driver Henry Ho spun his BMW into the gravel at Williams corner at mid-distance and Mehdi Bennani did not complete a lap as his Wiechers-Sport BMW stopped on-track during the opening few minutes.
Things got even worse for the team when Masataka Yanagida stopped his car with smoke pouring from it late on. That brought out the red flags and caused a premature conclusion to the session.
