  • Coupe bodystyle loses practicality
  • Off-road bodykit looks awkward
2023 BMW 740i Summary

The BMW 7 Series is Munich’s flagship, the car that fans of the blue and white roundel respect as peak plush motoring.

Now, for the seventh 7 Series, BMW has brought electric power to the table in the form of the i7 in order to stay ahead of the curve.

It’s still joined by a petrol-powered variant here in Australia, the 740i, which is a mild hybrid and shares a lot of the luxury specifications of the i7 - including a properly impressive rear seat theatre screen.

But is it forward-thinking enough to fend off the likes of the Mercedes EQS?

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…
