The Hummer H4 or HX^[1] is a proposed SUV reportedly in development by the General Motors Hummer division. GM may have a finished model to introduce to the market in 2008 or 2009. It is expected to compete with the Jeep Wrangler for market share. The development on new Hummer models so far has been towards SUVs that are more suitable for city traffic, a development which culminated in the Hummer H3. However, the H4 is likely to be more basic, and the focus is once again on off-road ability.

The H4 will likely be smaller than the three previous Hummers (including the H1) and is reportedly conceived to compete with the Jeep Wrangler. The design and look of the H4 has not yet been decided as GM is still deciding on what platform to build the H4. It is, however, likely that the H4 will use a shortened version of the platform currently used by the H3.

The H4 powertrain is reported to consist of two engine choices, the GM Vortec 3700 3.7L I-5 (242 HP) and the GM Vortec 4200 4.2L I-6 (291 HP). The transmission choices will be an Aisin 5-speed automatic or 5-speed manual.
