For 2008, the Hummer H2 and H2 SUT received an update. While essentially unchanged on the exterior, the H2 and H2 SUT interiors were redesigned. This included a new instrument cluster with improved gauges and Driver Information Center (DIC) based on the higher-trim
GMT900 trucks/SUVs, a new leather-wrapped steering wheel, three new radios with a
Bose premium audio system and auxiliary audio inputs (including a new touchscreen GPS navigation radio with DVD audio and video playback while the transmission is in the park position, and XM Nav-Traffic capabilities), a new rear seat DVD entertainment system,
Bluetooth hands-free calling capabilities, enhanced voice activation, new
OnStar hardware with buttons moved from the rearview mirror to the overhead console, a lower dashboard-mounted radio, new dual-zone climate controls, new rear seat audio system controls, a new dash-mounted control knob for the 4X4 system to replace the old pushbutton controls, brushed aluminum interior trim panels, new interior color options, available remote engine start, and a center dashboard-mounted analog clock. Also for 2008, a new 6.2 L V8 gasoline engine replaced the previous 6.0 L, with a new 6L80-E six-speed automatic transmission, replacing the 4L65-E four-speed automatic. Hummer launched a special 2009 Black Chrome Limited Edition featuring a new paint color, Sedona Metallic. All Black Chrome editions also had Sedona interior, black chrome accents instead of standard chrome, and unique 20-inch black chrome wheels. Initially, there were supposed to be 1,000 to 1,300 Black Chrome editions. However, due to the mid-year production shutdown, only six were ever actually made, and they were not made available to the public. ==Fuel economy==
