The scheduling of three Carline NSSS rounds on consecutive nights in January was the catalyst for the rebirth of the Tri-City concept last season and it was Victorias three-time national champ in Michael Nicola who emerged as the 2008/2009 APCO Tri-City Challenge champion. The 2009/2010 version will again see Western Speedway in Hamilton hosting the first night of com petition on Friday 8 January, followed by Borderline Speedway, Mt Gambier on Saturday 9 January, and Premier Speedway, Warrnambool, on Sunday 10 January.

APCO Warrnambool has provided support through proprietor Edgar Tanner with the provision of a $1,000 cash bonus to the overall winner! The Tri-City Challenge champion will also receive a trophy provided by the three clubs hosting the event.

Open to both Carline NSSS contracted drivers and non-contracted drivers alike, it is expected that such an incentive will again see a number of non-contracted drivers enter all three rounds. Queenslands Wayne Randall - winner of the Mount Gambier round last season - has already indicated that he will again be contesting all of the Tri-City events for Tasmanian car owner Steve Jessop.

The Tri-City Challenge offers an opportunity for Super Sedan fans to travel and witness some of the best Super Sedan racing of the season. With all three tracks situated within a two hour drive of each other, great crowds are again expected at each track.

APCO has its origins in petroleum wholesale distribution in the western districts of country Victoria in the early 1970s. APCO pioneered petroleum and convenience store retailing by recognising a niche in the regional Victorian marketplace and, in 1978, opened its first APCO EASY SHOP convenience / fuel retail centre in Warrnambool, beginning a new era of high quality, modern and well-equipped Convenience Store / Service Stations. Today there are 18 APCO EASY SHOP locations in the areas of Geelong, Bendigo, Ballarat, Bacchus Marsh, Warrnambool, Wangaratta and Melbourne.

Due to the terrific support of APCO Warrnambool, the Tri-City Challenge is again shaping as one of many highlights in what will be the best Carline Mufflers National Super Sedan Series ever. APCO Warrnambool is conveniently located at 485 Raglan Parade, Warrnambool.
