Isuzu has unveiled its all-new D-Max pickup in Thailand – the full model change version made its debut yesterday, ahead of the similarly-underpinned Chevrolet Colorado, which is expected to be introduced next week.

Not many details about the vehicle abound, but according to the Bangkok Post, the basic shape for the vehicle – which sits on Isuzu’s new i-Grip platform – in its extra and double-cab versions are pretty much the same, and that the new D-Max rolls in with significantly more heft in terms of overall dimensions compared to the outgoing one, even though no figures were available for it at press time.

The company says that the new D-Max’s body is 42% stiffer than the old one, and will help bring about improved handling and ride. In the double-cab, the larger dimensions of the vehicle bring about more legroom space for rear occupants, who also get more comfy seats at the back.

In terms of engines, three turbodiesel options abound – a 177 hp and 380 Nm 3.0 litre heads the list, followed by a 2.5 litre mill in two output tunes, the first being the familiar 116 hp and 280 Nm as seen on the current vehicle, and the other the VGS version offering 136 hp and 320 Nm. As for transmissions, there’s the usual five-speed manual, but the auto tranny is now a five-speed unit, bringing it in line with current expectation.

Among the features to be found on the new ‘un are traction control and a vehicle stability system, and there’s even an eight-speaker audio system, replete with surround sound. Sales of the vehicle, which will be available in 4×2 and 4×4 configurations, are expected to begin in early October in Thailand.

In related news, Isuzu also announced that it will be constructing a new plant in Thailand to bring up its production capacity to meet the increasing demand for pickup trucks and their derivatives. The new facility – consisting of new painting facilities, 2,000t servo press facilities and assembly/inspection lines – will be built within the Isuzu Motors Thailand Gateway plant.

The new factory, to be built at an estimated cost of 18 billion yen, is slated to begin operation by autumn 2012, and when it is completed, Isuzu Motors Thailand’s pickup truck production capacities in both its Samrong and Gateway plants will be increased to 400,000 units yearly.
