2026 GWM Tank 300 Summary

Sometimes it really is all a matter of timing.

GWM was always going to offer up the plug-in hybrid version of its Tank 300 4X4, but for it to arrive in showrooms right now must be being looked on as some kind of blessing at GWM HQ.

Consider the circumstances: The Tank 300 Hi4-T PHEV (to give it its full name) not only saves fuel by making use of plug-in hybrid tech, but the fossil stuff it does use is petrol, not diesel with that fuel’s buck-a-litre cost penalty right now.

And with the planet on a knife’s edge waiting for the next increase in brinkmanship from those referred to as our world leaders, overseas travel has never seemed sketchier to the average Aussie. Which is when keeping it local and hitting the outback in a four-wheel drive suddenly looks really, really good. Except for the cost of fuel, that is, which is where we circle back to square one.

All of which means the GWM Tank 300 Plug-in hybrid concept could not really have come at a better time. But does the reality match the promise?

2026 Mercedes-Benz GLB-Class Summary

A new-generation Mercedes-Benz GLB is just around the corner, so the current model is now on its farewell tour.

When it launched in 2019 it stood out from the crowd as a premium small-to-medium SUV with the flexibility of seven seats. Even now no other premium carmaker offers a car that’s a direct rival to this. You need to look at mainstream options instead that are slightly larger.

A mid-life update that arrived in 2023 brought some minor tweaks including different exterior and interior styling, along with mild-hybrid power for certain variants.

On test here is the entry-level GLB200 which didn’t receive mild-hybrid assistance. Read along to find out whether it’s the pick of the line-up.
