The 2008 HUMMER H2 and H2 SUT have a completely redesigned, more refined interior that combines luxury with HUMMER’s legendary ruggedness; enhanced safety features and a more powerful engine that is coupled with a new, six-speed automatic transmission. The new powertrain combination improves efficiency when compared with previous models. The heart of the ‘08 H2 is a new, 6.2L V-8 engine that uses variable valve timing technology to maximize performance and fuel efficiency. Its preliminary rating of 293 kW (393 hp) marks an increase of about 20 percent over the previous engine and is combined with 574 Nm of torque. The engine also features lightweight materials, including an aluminum cylinder block, which helps reduce the vehicle’s overall mass. A new six-speed Hydra-Matic 6L80 RWD electronically controlled automatic transmission backs the 6.2L engine. The six-speed automatic has a wide overall ratio – including two overdrive gears – that helps deliver an excellent balance of performance and fuel economy. Also, the 6L80 has a “tap up/tap down” capability that allows the driver to manually select upshifts and downshifts with a button on the column shifter.
