Gallery: Supercars testing at Ipswich

Supercars’ heavyweight teams are on track at Queensland Raceway today ahead of the Century Batteries Ipswich SuperSprint.

Shell V-Power Racing and the Red Bull Holden Racing Team are both utilising their first home track test of the season a week prior to the race weekend.

The Holden squad has five cars at the circuit, with its main entries joined by its Dunlop Super2 Commodores and Sandman ride car, pictured above.

Now fitted with a V8 following work in 2017 as a V6 turbo development mule, the Sandman is undergoing a shakedown, and being used by Supercars' technical staff for engine software testing.

The Red Bull HRT's co-drivers Craig Lowndes and Garth Tander are at the track, with the former driving the Sandman, while the Shell team has one of its additional drivers, Tony D’Alberto.

Matt Stone Racing is also running its championship entry, giving newly confirmed co-driver Jack Smith his maiden run in Todd Hazelwood’s Commodore.
