2020 BMW M135i Summary

When the iPhone first appeared just over a decade ago, I can remember thinking a phone without buttons would be a giant pain in the neck. Until I used one, and now the idea of a keypad phone sounds akin to starting a car with a crank handle.

The new 1 Series is likely to offer most buyers a similar revelation, with its move from the BMW-traditional rear-drive layout to more conventional front and all-wheel drive. That is assuming you gave a damn in the first place, as I suspect it’s only hardcore BMW traditionalists that care about a rear-drive premium hatchback in 2020.

And that’s not who is buying the 1 Series, with the Bavarian brand’s cheapest model intended to appeal to younger buyers who are more likely to care about connectivity, practicality and personalisation options than the excitement of losing grip from the rear. It certainly hasn’t stopped plenty of people from buying 1 Series-rivalling A-Class and A3s from Mercedes-Benz and Audi over the years.

2021 Mercedes-Benz C63 Summary

If you know the Mercedes-AMG C 63 S, you know it’s a hardcore V8 thumper with little in the way of bashfulness. It’s a brawler. A beast. 

Now there’s an even more eye-catching AMG C 63 S Coupe, which we’re testing here. It’s the Aero Edition - a collector’s version of the current-generation C 63 S Coupe with a bit more visual bling that also helps it stick to the road better.

It is a local area special edition, with only 63 examples to be sold across Australia and New Zealand. And if the rumours are true, the next-generation will see the V8 engine in danger of being axed in favour of a hybrid, high-performance four-cylinder version. Say it ain’t so! 

Well, if the CarsGuide crystal ball turns out to be right, maybe one of these C 63 S Aero Editions is worth getting in your garage quick-smart. Or is it? Let’s go through the criteria and see how it stacks up.
