2026 Toyota Tundra Summary

The Toyota Tundra, made in America for Americans, was launched in 1999 and since then Toyota Australia has fielded a steady stream of enquiries from car buyers and automotive media about the possibility of its full-size US pickup being available in local showrooms.

Production of RHD Tundras at Toyota’s San Antonio plant in Texas never stacked up as a viable business case for Toyota until 2015, when the Walkinshaw Automotive Group (WAG) commenced OEM-certified right-hand-drive remanufacturing of Ram pick-up trucks (and later Chevrolet Silverados) in Melbourne.

This development finally opened the door to an ‘Australianised’ version of the Tundra, which went on sale late last year after a six-year joint development program with WAG that was a world-first for Toyota.

The Tundra’s local two-model range comprises the entry-level Limited and the new top-shelf Platinum grades, with more power and torque than local ‘1500 class’ US pickup rivals. So, we recently put the fresher Premium model to work for a week, to see how it measures up from a tradie’s perspective.

2026 Mercedes-Benz Gls450 Summary

The ‘Upper Large SUV over $120K’ segment of the Aussie new-car market is what you might call the top end of town, not only in terms of the extravagant models available but also their purchase prices, which stretch well into six figures and require monthly lease payments that rival home mortgages.

It’s where you’ll find some of the most prestigious marques in the automotive world including Rolls-Royce, Aston Martin, Bentley, Ferrari, Lamborghini, Range Rover, Lexus and BMW. And, of course, Mercedes-Benz with its big GLS which represents the flagship of the German manufacturer’s SUV fleet.

It was given a refresh in 2023 with cosmetic and multimedia upgrades along with powertrain enhancements, but there have only been minor changes since then. We were recently entrusted with the keys to the latest GLS to see if the ‘S-Class of SUVs’ leaves any room for improvement.
