The new HSV6000 sedan not only takes the high performance four-door to a new level with the 400hp 6.0 liter LS2 under the hood but is a preview of a new driver interface system via a PDA. HSVs DDIDDI is collaboration between the Holden Special Vehicles team and GM's Tech Management Group and creates not only a navigation tool but also communication between car and driver. Via a data bus incorporated into the vehicle's electronics, the driver can monitor everything from fluid temperatures to vehicle performance. The DDI unit should become available in other HSV models later this year. No word on if DDI would make its way to GM performance lines in North America.
