2008 HUMMER H3
March 31st, 2008 | by Ed |Expressive, refined HUMMER-brand ambience
The interior design of the HUMMER H3 represents the start of an entirely new design theme for HUMMER. From the outset it was designed to be a vehicle for everyday driving and that focus strongly influenced the design, with comfort and intuitive function as key factors.
The H3’s interior design is expressive, refined and true to the brand’s ambience. The interior fittings have tight panel gaps and flush surfaces, and the tone is lightened with the use of bright trim accents and the use of colour.
Front and rear, there is generous head, leg and shoulder room. The perception of roominess within the vehicle is boosted by a headliner trimmed in a pale tight-weave fabric. The pillar mouldings are finished in the same colour to harmonise with the headliner. The large 916 x 624 mm powered sunroof offered on the H3 as an option can be opened, closed or set to the ‘vent’ (tilt) position.
The centre stack, which is a flush fit to the dashboard, is finished in a new material called Nissha. This material carries a metallic finish for a premium look, but is resistant to light reflection and smudges – for excellent wear. Nissha is also featured in the instrument cluster, which is positioned to ensure an optimal view of the road and maximum clarity for its easy-to-read liquid crystal displays. A driver information centre includes four levels of controls arranged horizontally for easy use.
The standard easy-opening, one-piece tailgate makes for convenient loading and unloading of the cargo area which measures 1273 mm wide x 811 mm long with the rear seats upright. In this mode, capacity is a generous 835 litres and folding down the 60/40 split rear seat expands cargo volume to 1597 litres.
Tough, durable materials protect the cargo area sidewalls, while the floor is covered by a rubberised Tufflor material, which is superior to traditional carpets, mats or rubber floors in its resistance to scratches and damage.
H3 customers have a choice of five interior colour combinations – all Ebony and Ebony with Light Cashmere seat cushion inserts for the standard cloth seats. For the leather trim, the choice is all Ebony with Pewter piping, Ebony with Morocco-toned seat cushion inserts and piping, or light Cashmere with Ebony piping.
Power, torque and Maximum Drivability
The 2008 HUMMER H3 is powered by GM’s inline five-cylinder Vortec 3.7-litre petrol engine. This all-aluminium ‘smart engine’ is both high-tech and lightweight and is fitted with dual overhead camshafts, electronic throttle control and variable valve timing. Specifically designed for this type of vehicle, it delivers 245 ps at 5600 rpm and 328 Nm of torque at 4600 rpm. For superb drivability both on- and off-road, 90% of the engine’s torque is available across a broad rev-range, from 2000-to-6000 rpm.
The Vortec engine provides the H3 with excellent performance combined with good controllability for easy off-roading. On the road, the comfortable ride is matched to lively acceleration that equals the V8 powered H2 in most driving conditions. The Vortec engine’s advanced technologies, including counter-rotating balance shafts, which help to minimize noise, vibration and harshness.
Electronic Throttle Control (ETC) with Sequential Electronic Fuel Injection (SEFI) eliminate the throttle cable and provide outstanding throttle response both on- and off-road. Coil-on-Plug ignition does away with spark plug leads, delivers high energy and cuts exhaust emissions while stretching fuel economy – up to 20.4 mpg (combined cycle).
H3 was the first HUMMER to offer the choice of a manual or automatic transmission. In addition to the standard five-speed manual transmission, which is a fun option for the serious off-road performance enthusiast, offering the ultimate driver control, customers can opt for the Hydra-Matic 4L60-E electronically controlled four-speed automatic.
