Supercars has summoned a car from each manufacturer for the testing, which will take place across Queensland Raceway and Bathurst.<\/p>\n
Running is scheduled for the Ipswich venue on February 9 and 10 before the cars head to Mount Panorama for sessions during that weekend\u2019s Bathurst 12 Hour event.<\/p>\n
That leads directly into Sydney 500 week, which includes a full-field pre-season test at Sydney Motorsport Park on Wednesday, February 18, and the weekend\u2019s race meeting.<\/p>\n
The track outings will follow December\u2019s aerodynamic testing at the Windshear wind tunnel in the United States<\/a> and dyno-based engine evaluations that are currently taking place in Brisbane.<\/p>\n \u201cThe QR testing and the [Bathurst] 12 Hour are further data points for us to assess where we\u2019re at,\u201d Supercars\u2019 motorsport boss Tim Edwards told Speedcafe.<\/p>\n Supercars is handling pre-season dyno testing locally through its engine partner Cragsted, rather than returning to the AVL facility in the US that it last used midway through 2024.<\/p>\n The category has flagged plans to visit an AVL dyno in Austria at some point later in the year.<\/p>\n \u201cWe\u2019ve got a plan that we\u2019re working through with the three HTs (homologation teams) using all the tools we\u2019ve got at our disposal,\u201d said Edwards.<\/p>\n \u201cEveryone is comfortable that we\u2019ll tick off the key parameters we\u2019ll need to tick off.\u201d<\/p>\n There is significant intrigue over the current performance of the 5.2-litre version of Toyota\u2019s 2UR-GSE V8 that has been developed in conjunction with UK firm Swindon for use in the championship.<\/a><\/p>\n Ford rival Brodie Kostecki claimed earlier this week that the engine is \u201cquite far behind\u201d, predicting grim results for the new player in the first part of the season.<\/a><\/p>\n Edwards confirmed a second iteration of the engine is now up and running on the Cragsted dyno, although declined to share details of any specification changes.<\/p>\n \u201cThe way we\u2019re describing it is it\u2019s the production version, and we\u2019ve got more than one sitting at Cragsted,\u201d he said.<\/p>\n \u201cYou always build prototype engines and then as you hone in on the final product, you produce a production version.\u201d<\/p>\n Asked of his confidence of having engine parity from the start of the season, Edwards noted the quad-cam nature of the Toyota makes it easily tuneable.<\/p>\n \u201cIt\u2019s not like the [pushrod] GM where once you\u2019ve got a camshaft in it\u2019s hard coded, the only tool you\u2019re left to play with is the restrictor,\u201d he said.<\/p>\n \u201cWe\u2019re fortunate the Toyota is like the Ford and we can move the camshafts around as we need to achieve the same power curve as the other two.<\/p>\n \u201cIt\u2019ll be a combination of moving the cams, the normal calibration work and the restrictor size.\u201d<\/p>\n The category intends to start the season without any shiftcut offset across the three brands \u2013 a tool it used as recently as last year when trying to balance the Ford and GM.<\/p>\n
