Isuzu D-Max is a pickup truck made by Isuzu. It shares the same platform with several General Motors (GM) mid-size trucks in the United States. These being the Chevrolet Colorado, GMC Canyon and Isuzu i-Series. The Chevrolet Colorado name is also applied to a rebadged version of the D-Max in Thailand, although not identical to the American version. The original D-Max is sold alongside the Chevrolet Colorado in the Thai market where they are both built. In Australasia between 2003 and 2008, the D-Max was marketed as the Holden Rodeo, but has since been relaunched as the Holden Colorado. The Isuzu D-Max itself was also introduced in Australia during 2008, selling alongside the Holden offering.
In the third quarter of 2006, the D-Max received a minor redesign and the introduction of a third DDi iTEQ engine, 3.0 4JJ1-TCX. This engine is a modified 4JJ1-TC, incorporating a new Variable Valve Geometry Turbo (VVGS). The extra power warranted an introduction of new transmissions as well: the MUA5H 5-Speed manual and MaxMatic-III automatic transmission. All models equipped with Xenon headlamps were changed to projector headlamps instead. Also introduced was the new "Hexapod-plot" interior. Other DDi iTEQ engines were also tweaked a bit for extra power and efficiency.
During the middle of the first quarter of 2008, Rodeo LS and Hi-Lander SpaceCab were also fitted with the 3.0 VVGS Turbodiesel engine to fill all the remaining gaps in lineup. Early fourth quarter of 2008, Isuzu introduces D-Max Platinum models for 2009 to replace the outgoing Gold Series. New exterior colors to the selected models. LS 4x4 and Hi-Lander received new fascia; chrome on LS 4x4 and semi platinum-silver on Hi-Lander. Minor-modified headlamps and new fog lamps for platinum look. Revamped fenders and side trims with chrome trim. 4x2 SLX and SX derived fascias from 4x4/Hi-Lander (before Platinum's fascia) and revamped side trims without chrome trim. Chrome fascia for 3.0 SLX models and color-keyed fascia for SX. Top heads of 3 DDi iTEQ engines changed from gold to platinum. Some models dropped 4JJ1-TC 3.0l engine. All retooled to be acceptable with Biodiesel B5. Interior changed to platinum tone. Cab4 LS also featured new sumptous leather upholstery in black. Several highline models featured Platinum Entertainment package (by Kenwood): included DVD/VCD/MP3/DiVX player and 6.1" touch-screen; compatible with iPod, Bluetooth, TV tuner and navigation system. Additionally also featured rear view camera for reverse assist (Platinum Vision). All SpaceCab models featured new middle pillars called Safety Pillar Cab; pillars and door beams larger and thicker. Not all Cab4 models received retooled rear suspension called Super Flex Plus suspension. Badges and rings which were once gold are now in silver/platinum as well. Spark EX also received new gauge and indicator. D-Max Platinum models commenced on sale from 15th October.
