Gm Mild Hybrid
It looks like the Volt won't be the only alternative-power variant of GM's next generation Global Compact Car or Delta platform. While Delta is the source of a lot the hardware for E-Flex, it is also the basis of the Opel/Saturn Astra and the Chevy Cobalt. German magazine Automobilwoche is reporting that a hybrid version of the next Astra is under development. That much is almost certainly true but they are also reporting that the Two-Mode Hybrid system is being used.
