ISUZU is not one to rest on its laurels.

Only a year after updating its MU-X large SUV and D-Max pick-up, the Japanese brand is back with a number of small tweaks to its popular diesel-powered 4x4 range.

Implementing its changes following feedback from customers and the media, Isuzu Ute is hoping a refreshed and improved product line-up will help spur double-digit sales growth for the tenth consecutive year – every year since Isuzu Ute launched in Australia in 2008.

While most elements – including exterior styling and the venerable 3.0-litre turbo-diesel powerplant – remain the same, there are more subtle changes including a new leaf-sprung suspension set-up for dual-cab versions and a new, permanent range-topper in the form of the LS-T.

The changes are useful but minor, and it remains yet to be seen whether the tweaks are enough to ensure a sales boost.

Are Isuzu’s changes sufficient in spurring the burgeoning 4x4 brand on to its tenth consecutive year of double-digit sales success?
