Accessories

One of the industry’s broadest portfolios of vehicle accessories has been developed for the H3T. Centered on active lifestyles, items such as removable and lockable bed-mounted storage boxes; an adjustable bike chock that can be used to help secure mountain bikes or motorcycles; and a bed extender make full use of the standard bed-rail cargo management system. A range of additional accessories that improves off-road capabilities, provides passenger entertainment and enhances exterior styling is also available. There are more than 75 HUMMER Genuine Accessories offered.

In addition to the factory-developed accessory portfolio, HUMMER has partnered with top automotive aftermarket companies to develop more than 50 Officially Licensed HUMMER Accessories – a first for the brand. A variety of exterior enhancements, such as a Slant Back Bed Cover, hard tonneau covers and a winch are offered, along with cargo management solutions such as the BedSlide and bed divider, offering countless possibilities to personalize the H3T.

Interior

The H3T’s crew cab cabin offers seating for five adults, with a 60/40-split rear bench seat that folds flat for increased cargo-carrying options. The cabin’s layout is essentially identical to the acclaimed H3 SUV, with premium materials and attention to detail that give the vehicle a functional yet refined aesthetic.

Standard amenities also include air conditioning, power locks, power windows and remote keyless entry. An AM/FM radio with CD is standard and a premium Monsoon audio system is available. XM Satellite Radio also is standard and includes three months of trial service.

HUMMER’s Rear Vision system and a navigation system are available. The Rear Vision system uses a camera mounted on the rear bumper, directly above the trailer hitch mount, to provide a view of objects directly behind the vehicle. Also, the safety and security of OnStar is standard, with Turn-By-Turn Navigation and hands-free Bluetooth connectivity available.

Powertrain

Standard in the H3T is the Vortec 3.7L I-5 with dual overhead cams and variable valve timing. This inline five-cylinder engine offers an excellent combination of power and efficiency, delivering 242 horsepower (180 kW) at 5600 rpm* and 242 lb.-ft. of torque (328 Nm) at 4600 rpm. It is backed by a five-speed manual transmission or an available four-speed, electronically controlled automatic.

The H3T Alpha’s 5.3L engine is a powerful and efficient member of GM’s legendary small-block V-8 family. It is rated at 300 horsepower and 320 lb.-ft. of torque. An aluminum cylinder block is used with the H3 Alpha’s engine. It helps reduce overall mass and maintains a more desirable front-to-rear weight balance.

A Hydra-Matic 4L60 electronically controlled four-speed automatic transmission is paired with the 5.3L engine. Flat towing is enabled on all H3 and H3T models.
