AWD Subaru BRZ to hit the Rally stages in Australia

Share

Yes, you read correctly, an AWD BRZ.

In 2017, Peter Dunn competed in the Australian Rally Championship with his 2006 STi Spec C. “We were pleased with the performance and set up of the STi. However, we decided it was time to step things up and starting looking at vehicle upgrade options. We were in the situation that other competitors are facing: a shrinking market of suitable and affordable modern factory AWD vehicles.”

This led to Peter looking beyond the standard factory options, to develop a unique rally car that can deliver not only on performance but also on visual appeal. He has achieved this by building a vehicle that leverages the freedoms granted by the CAMS G4 regulations, using an existing homologated driveline integrated with a newer and lighter body shell.

Peter explains, “We’ve succeeded in developing a viable vehicle conversion package that will deliver the competitive AWD rally car that we are looking for, and within a reasonable budget.”

Featuring a turbocharged 2 litre STi motor coupled with a 6-speed AWD transmission, this BRZ comprises a unique setup that is designed to maintain its natural handling balance, with widened bodywork and an AP4/G4 compliant rear wing that will keep the car well planted.

Substantial research and development effort has gone into this project, and the team is now working towards preparing the BRZ for it to be inspected to complete the required CAMS G4 recognition process, before tackling next year’s ARC. This process will ensure that CAMS has approved the vehicle for G4 prior to it entering any competition as a G4 car.

The team is not taking the development of a new concept lightly and is planning to test the car extensively until they are satisfied on the cars performance and reliability, making use of the 2018-19 NSSCC Summer Rally Sprint series at Eastern Creek and the Hills District Car Club grounds at Hampton, NSW.

In the meantime, Peter is expecting to return to the ARC for the 2018 Bott Adelaide Hills Rally in the STi and to give the car one final run in the WRC at Rally Australia.
