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 C350 E Summary

They're doing it again! Actually they've been doing it again for a bit now. It’s Mercedes-Benz Australia and plug-in hybrid tech.

The Ross and Rachel, or Jim and Pam of the premium automotive world.

It's been a will they, won't they for a while, and in the past Mercedes has dipped its proverbial plug into the electrons a few times and gotten cold feet.

But now it says it’s all in. There are others, the GLA and GLC SUVs, plus there’s the new C63 performance car, but this one feels like a bit of an arrival.

Yeah, the C-Class is no longer the Mercedes-Benz in terms of sales, but it might be the best way to make the most of a bit of battery power.
