The CTS and SRX are built on the Epsilon platform which, surprise surprise, will probably underpin the next Opel Omega and most of the big rwd Holdens.
Cars like the Saab 9-3 are built on the Sigma platform which of all things is also used to underpin the new Chevy Malibu.
You got you lines crossed... CTS and SRX are on Sigma... 9-3, Malibu, Vectra are on Epsilon
