2023 Mercedes-Benz C43 Summary

Think of a Mercedes-AMG and the first words that spring to mind are probably not - understated, efficient and restrained. And yet those are probably the best words to describe the all-new C 43.

Of course, before we go any further it’s important to note that the C 43, even in its previous six-cylinder guise, was never meant to be as wild, raucous or powerful as the C63 flagship - that’s simply not its role in the AMG line-up.

But even so, this new model is a dive into fresh territory for the brand and puts a very different spin on the AMG sports sedan as we know it.

This is a four-cylinder model, complete with a Formula One-derived electric turbocharger, so it lacks the sound and fury you expect from something carrying the ‘AMG’ badge - but that doesn’t mean it’s a bad car, as we’ll explain.

2025 Rivian R1S Summary

An American all-electric car brand with a unique take on the automotive industry, an up and down share price and a cheaper model in its future plans. You could be mistaken for thinking I’m talking about Tesla, but I’m not.

Recently CarsGuide got the opportunity to experience an alternative electric car brand, and one that, despite having many similarities to Tesla, is also in many respects its polar opposite.

I’m talking about Rivian, which is very much behind Tesla in terms of sales, market cap and just about every other measure. But what it does have is a compelling line-up of electric vehicles, with plans for expansion, including an eventual entry into Australia.

Back in 2023 we drove the brand’s ute, the R1T, but on a recent trip to Los Angeles we sampled the brand’s other model, the R1S SUV. It was an eye-opener to see how far the brand has come in two years and showcased just how different Rivian is from Tesla.
