2017 BMW 230i Summary

If one is good, two must be better, right? Or twice as good. The question is whether that simple equation adds up for BMW's upgraded 1 and 2 Series siblings – the former, a range of five-door hatches, the latter, a line-up of cabriolets and coupes, with a major addition in the shape of the full-house, performance-focused M2.

Prices are up, and changes are mostly under the skin, so you're not getting  big visual bang for your extra bucks. But the new and improved 2 has plenty to offer when it comes to added spec and tech.

BMW invited us to the new car's Australian launch program along Tasmania's wet and wild west coast.

2021 Audi S4 Summary

Audi would probably prefer you not to realise this, but the five distinct versions of S4 and S5 on the market all pertain to a single performance and equipment formula spread across five different bodystyles. 

Yes five, and this has been the case for more than a decade, with the S4 sedan and Avant wagon, A5 two-door Coupe, convertible Cabriolet and five door liftback Sportback all representing vastly different shapes for you to choose from, with the same underpinnings. This simply echoes the A4 and A5 ranges they’re based on of course, and BMW clearly thought it was a good idea too, given the 3 and 4 Series ranges were split into individual lines at the start of last generation.

Mercedes-Benz offers a similar array, minus the liftback, but is happy to wrap the whole lot under the C-Class label. 

So, given that the A4 and A5 range scored a mid-life update a few months ago, it’s only logical that the changes flow on to the performance S4 and S5s, with the top-tier RS4 Avant following suit. 

We’ve covered the latter in October, and now it’s the turn for the former, and CarsGuide was among the first to drive the updated S4 and S5 ranges at their Australian media launch last week.
