2026 Porsche Cayenne Summary

No good deed goes unpunished.

Porsche, a brand synonymous with petrol-guzzling sports cars, tried to do the right thing and make a nearly wholesale switch to electric vehicles by the end of the decade. The problem was, while this made governments happy, it didn’t sit well with customers.

Porsche’s all-electric Macan is enduring a torrid 2026, with sales down over 75 per cent now that all the petrol-engined options are gone. 

But that hasn’t stopped the German brand trying again with an all-electric Cayenne. However, there are some key differences that mean this latest electric Porsche won’t suffer the same fate.

Namely, the petrol-powered and hybrid versions aren’t going anywhere and new versions are rumoured to be coming in the not-too-distant future.

For now though, we have this all-new electric Cayenne - so how does it stack up to its predecessors as the sports car brand’s big SUV?  And will it be second time lucky for Porsche’s electric transition? Based on two rather unorthodox days of test driving, the verdict might surprise you…

2020 Mercedes-Benz GLE300 Summary

Not so long ago, even the idea of 'coupe SUV' would have been considered just a little bit silly.

But not anymore. This almost contradictory bodystyle is well and truly here to stay, as evidenced by the expanding catalog of available models pouring out of premium automakers.

Benz tells us, for example, that coupe versions make up some 25 per cent of its GLE sales in Australia.

Which brings us to this car – the second-generation GLE coupe. We were sent to its international launch to find out what’s new, what’s changed, and what Benz has in store for the Australian market, come its arrival in Q3 of 2020. Read on to find out what we discovered.
