The Hummer H2 returns for 2008 with minor changes. It remains available in an SUV or SUT truck bodystyle. The new 393 horsepower 6.0L V8 engine, that uses variable valve timing technology to maximize performance and fuel efficiency, is mated to a six-speed automatic transmission. Interior updates include a redesigned instrument panel, new seats with a full third-row seat for two passengers, new door trim panels, new controls, new rear-seat heating/air conditioning system, and new rear-seat overhead DVD entertainment system. New standard safety features consist of a new electronic stability control system with rollover mitigation technology, panic brake assist and roof rail head curtain side air bags with rollover sensing system.
