2026 BMW X Models Summary

When the BMW iX first showed up a few years ago, it was a promising look at what BMW seemed capable of when it comes to electric cars.

While mildly flawed, the iX was fast, comfortable and felt properly premium. Now it’s had a decent update, with the iX xDrive45 M Sport here to replace the former entry-level xDrive 40.

BMW claims among other mechanical and tech updates a power increase of 25 per cent, a 30 per cent greater energy content for the battery, a 38 per cent increase in driving range and a 17 per cent faster charging rate.

But in the time since the iX launched, there have been big strides in the premium electric SUV space, including new arrivals from European opposition like the Polestar 3; even a new American in the form of the Cadillac Lyriq.

2018 Mercedes-Benz S300 Summary

Imagine a car that can pretty much drive itself, if you let it. And it’ll do that while you get a massage, pump some Beyonce, and enjoy the fragrance of a field full of flowers… And then, it can teach you to do stretches and exercises in the driver’s seat.

It may sound like fictional fiction, but it’s factual fact. And it’s the Mercedes-Benz S-Class 2018 model, which has taken the so-called ‘wellbeing’ of the driver to a new level.

The facelifted model has seen plenty of styling changes and some tech upgrades, and while making the flagship car in a particular brand’s line-up is often a task fraught with issues, the German company’s big, expensive, luxurious, limousine is undoubtedly a more thoughtful car for 2018.

But just remember, its predecessor was considered - at least for a little while - as the best car in the world by some automotive journalists. 

Now Mercedes-Benz has updated it, and it reckons it’s better than before, bringing a bunch of new technology, new engines, a reworked model range and, perhaps not essentially, but still pleasantly, lower pricing.

Read on to see how Beyonce factors into the equation.
