Jamie Whincup held out three Prodrive entries to lead the way in the opening practice session of the Sandown 500 weekend in Melbourne.
Whincup, driving a brand new chassis, emerged quickest from the last-minute flood of quick times as the circuit gripped up, a 1m09.516s handing him bragging rights at the end of the first session of the weekend.
Whincup’s late improvement demoted Prodrive Racing’s Chaz Mostert to second – 0.100s behind – while there was a further 0.270s back to Mark Winterbottom and David Reynolds.
Scott Pye was fifth fastest in the Penske entry, ahead of Shane van Gisbergen and Nick Percat.
Scott McLaughlin was the quickest Volvo in eighth, Jason Bright ninth, while Todd Kelly was the best Nissan in 10th.
Erebus V8 had a disappointing session, Will Davison just 20th fastest, while Craig Lowndes also had a shocking start to the weekend, managing just 23rd.
The rest of the day’s running is reserved for the co-drivers, with two 30-minute practice sessions to follow this afternoon.
