Click on the HCCI equipped Opel Vectra for a high-res gallery
There are rumors floating around the interwebs today regarding the Opel Insignia being the first official product from General Motors using its highly-efficient homegeneous charge compression ignition, or HCCI for short. We can't confirm these rumors at this point, as GM has made no official announcements at all regarding the future of its HCCI engines. We do, however, know that engineers in crisp white lab coats are currently hard at work perfecting the technology. Therefore, we'd expect their efforts to bear fruit sooner or later. Exactly what vehicle the HCCI engine will first appear in, though, remains a mystery.
