History of the Isuzu D-Max
A world premiere in Thailand
The D-Max had its world premiere in Thailand in 2002, a location chosen because General Motors and Isuzu had just closed their small truck plant in Japan and moved the joint operation to Thailand. The range started with a single-cab Spark, extended-cab SpaceCab and double-cab Cab4 models in two- and four-wheel drive, sold alongside an almost identical Chevrolet Colorado that arrived in 2004. The first engines came from the predecessor: the 3.0 4JH1-T and the 2.5 4JA1-T, both diesels. A lifted two-wheel-drive version called the Hi-Lander followed late in 2003, and Isuzu was the third maker in Thailand to offer such a model after Toyota and Ford.

DDi iTEQ engines
In October 2004 Isuzu introduced the DDi iTEQ common-rail diesel family, starting with the 3.0 4JJ1-TC of 146 PS. Every model received a mid-cycle refresh with a new front bumper that incorporated an instant spoiler underneath, and a new five-speed manual gearbox appeared. Early in 2005 a 2.5 4JK1-TC of 116 PS joined the range as the economical choice, and four-wheel-drive models and the Hi-Lander were raised by 25 mm.
Facelifts and special editions
The third quarter of 2006 brought a major facelift, the 3.0 4JJ1-TCX engine with a variable valve geometry turbo, new MUX five-speed manual and MaxMatic-III automatic transmissions, projector headlamps and a new interior. In 2007 Isuzu marked fifty years in Thailand with Gold Series models for 2008, and the Hi-Lander Cab4 received the VGS turbodiesel. Platinum models replaced the Gold Series in October 2008, with new grille designs, revised headlamps and fog lamps and engines retooled for B5 biodiesel; the SpaceCab gained a stronger Safety Pillar Cab, and some Cab4 models received the Super Flex Plus rear suspension. Super Platinum arrived in September 2009 with new alloy wheels, a rear bumper and a short-pole antenna. Special D-Max and MU-7 models were also built for Thailand’s two big motor shows.
