2023 BMW XM Summary

BMW’s new XM is a tricky customer to pigeon-hole. Yes, it’s a huge, super-lux SUV and, yes, it’s all-wheel drive and features a station-wagon layout.

But it’s also a M-car and that infers super high performance. Weighing in one the wrong side of 2700kg, however, makes that a difficult task for any engineer.

This car also left us wondering if perhaps the glory days of M Division sports cars and coupes might behind it and SUVs like this one represent the road ahead.

But fear not: The CEO of M Division himself, assured us that the XM is a showcase for what an M badge can do, rather than a mission statement for the brand.

So, with that in mind, does this car have the wow factor that places it somewhere between peak oligarch and a motor-show concept car? Does it move the goal posts for big luxury SUVs? Does it even matter that it’s a plug-in hybrid?

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…
