The strongman of the Cadillac family is still offered in its utility and full-scale truck versions. Depending on the chosen configuration, it can accommodate up to eight passengers. For 2009, Cadillac has added a new 6.0-litre V8 hybrid engine with a torque rated at 367 lbs/ft. Coupled with a dual hybrid transmission with continuous electric speeds, it offers fuel savings equivalent to those of a mid-sized sedan, around 11litres/100km, while driving in a civilised manner?
