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?

2020 Mercedes-Benz G63 Summary

Everything you need to know about the Mercedes-AMG G 63's personality pokes out from underneath the polished alloy steps running down each of its flanks. Side pipes… no one does side pipes.

A colleague was pulled over in a G 63 because the cops thought the '60s muscle car-style exhaust was after-market and illegal. But it's not, and it's brilliant.

Launched globally in early 2018, this brutal take on the second-generation Mercedes-Benz G-Class might look the same as the G 63 it replaces, but under the skin it's a whole new ballgame.

The first-gen was like grandpa's axe, regularly updated but underneath it all the same basic framework. This is a whole new axe, including a fresh drivetrain, suspension set-up and interior treatment.
