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…

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?

Verdict

There is a lot riding on this new Cayenne Electric, it is the sales leader for the German brand and if it suffers the same sales decline as the Macan, that will be a big concern for Porsche.

The good news is it’s an impressive all-rounder, with an incredible breadth of capability. But so is the electric Macan.

Going electric hasn’t diminished its trademark Porsche elements, and instead has amplified them in many respects. The speed is nothing short of staggering in the Turbo, but across the range the on and off-road driving ability is impressive.

Plus it has the kind of spacious, well-considered and premium appointed cabin you should expect for a luxury SUV.

There are two key differences that could see it succeed where the Macan has faltered. Unlike the Macan, Porsche’s decision to give Cayenne buyers the option to stick with internal combustion if they prefer, is likely to ensure it remains a popular member of its line-up for years to come.

And while the Macan was perhaps too much, too soon, the Cayenne arrives at a time when Australians are embracing electric cars more than ever before. Although the luxury and performance end of the EV market is growing more slowly than the mainstream.

As for the pick of the range, as mind-blowing as the Turbo is, the truth is (like pretty much every Porsche model) the entry-level Cayenne is arguably the pick of the bunch. It has all the performance you’ll reasonably need and offers a good blend of capability and luxury for the lowest price.

Verdict

While the new 7 Series won’t visually appeal to everyone, nor is it at the forefront of spirited driving dynamics, it’s hard to argue that it isn’t fit for purpose.

Its rear theatre screen and lounge layout might seem gimmicky at first, but it’s difficult to think of a more comfortable way to be transported on wheels short of putting a chassis under your loungeroom. Even then, you’d have to ask someone for a massage.

This is one of those cases where a car becoming larger isn’t such a bad thing, and BMW should feel like it’s achieved, seemingly, what it set out to do in building an electric limousine that doesn’t fall short in range or dynamics.

If BMW can bring this level of refinement down to its more affordable models, its electric future is looking promising.
