. Holden engineering director Tony Hyde said his engineers are not involved in any way in the V12 development. An Australian report had claimed that the
would be based on the new Zeta platform that underpins the other new RWD
cars with the V-12 being based on a pair of 3.6L V-6s joined together.
If the V12
come to fruition, it seems likely that the engine would be a development off the six cylinder, but the architecture would more likely be derived from the Sigma platform that the other RWD/AWD Cadillacs sit on. According to Hyde, all of his resources are being used to develop the Camaro/G8/Impala and other derivatives. If the
proves to be real, the Aussie team would likely be pretty busy with that as well.
