2019 Lexus RX450H Summary

This is a review with a difference. For three days, I had a Lexus RX450h and thought it was pretty terrible to drive. Every time I turned the steering wheel, the tyres would squeal as though they weren't inflated with air but instead with tiny, fluffy kittens.

I was bitterly disappointed. How could a car get out the door of the Lexus engineering division with such an aversion to corners. I mean, I know it's not meant to be a corner-carving monster, but normal cornering should have been okay.

After those three days, I'd had enough. The low tyre pressure warning light came on and the penny dropped. I hadn't even thought to check the pressures. They were very, very low. Like only at two-thirds of recommended. So after visiting three separate establishments to find a working pump, I had a whole different car.

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…
