Mercedes-Benz E400 vs GWM Tank 500

What's the difference?

It is hard to immediately think of a country more suited to the convertible life than Australia. Even our coldest states (you know who you are…) are blessed with more warming sun than almost anywhere else on the civilised parts of the planet, so you’d think we’d be swanning about in dropped-top bliss almost year round.

But it’s actually in the UK (despite being cold, grey and almost always underwater) that convertibles really fly out of dealerships, with sun-starved Brits buying more than anyone else in the world. Weird, right?

Still, here they remain something of an oddity, sold in small numbers to drop-top diehards. At least partly because the convertibles of old were almost always slightly worse than their hardtop equivalents. 

But Mercedes - which makes more convertibles than most - claims to have mastered the soft-top formula with the E400 4Matic, a car it says offers all the perks of open-air motoring without any of the dynamic or practical downsides. 

The arrival of the GWM Tank 500 Ultra PHEV is noteworthy because it’s the first plug-in hybrid Tank model in Australia.

It’s also a major event for the Aussie adventure-travel community because it’s a plug-in hybrid 4WD with five seats, high- and low-range gearing, and a front, centre and rear diff lock.

The Tank 500 PHEV gets more power and torque than its hybrid stablemate, offers about 120km electric-only driving range (listed), and it can be used as a 6kW mobile power station (V2L) at your campsite. Towing remains at 3000kg.

There’s a lot in this Tank’s favour: it’s a body-on-ladder-frame chassis large 4WD with a packed standard features list and real off-road adventure potential.

All of that – and more – for under $80 grand.

But does the plug-in set-up add anything substantial in terms of daily driveability or does it simply make this Tank an $80,000 camp-site generator?
