Wednesday’s pre-season test at Sydney Motorsport Park was a big one for Brad Jones Racing, which set the fastest lap and logged the most laps.
The test day, which featured a combined eight hours of running, was the first time all 25 Gen3 cars shared a track together.
Andre Heimgartner topped the time sheets in both the morning and afternoon sessions, both times ahead of Erebus Motorsport’s Will Brown.
Heimgartner's 1:29.6787s in the afternoon session proved the benchmark after eight hours of track time.
The Kiwi also logged 92 laps of Sydney Motorsport Park in his BJR-built #8 R&J Batteries Camaro.
Only two teams completed fewer laps than Erebus Motorsport's combined haul of 80, but the team was on the pace.
Brown and Brodie Kostecki ended the day second and third on the time sheets in their new Coca-Cola Camaros.
Van Gisbergen was seventh fastest
Shane van Gisbergen's afternoon time helped Red Bull Ampol Racing slot behind BJR and Erebus in the pace stakes.
Only two cars logged over 100 laps, and one of them was steered by Heimgartner's teammate Bryce Fullwood.
Fullwood's #14 Middy's Camaro recorded a combined 121 laps of Sydney Motorsport Park, or just over 473km.
All 25 cars combined to log 1658 laps of the 3.91km circuit, which totalled nearly 6482km.
Broc Feeney's #88 Red Bull Ampol Camaro, with Jamie Whincup also getting behind the wheel, logged 111 laps.
BJR’s four cars combined for 352 laps (1376km), with the two Red Bull Ampol Racing Camaro combining for 202 laps (789km).
Tickford Racing’s four Mustangs combined for 304 laps, with Cam Waters the team's quickest on the day with a 1:31.3408s.
A number of teams will test in the coming weeks before the new season commences at the Thrifty Newcastle 500 on March 10-12.
