BMW 5 Series vs Audi S4

What's the difference?

More than half a century of 5 Series pedigree has led BMW to this, the first electric version of its venerable sedan, the i5. 

It's true that electric cars come with benefits that suit the realm of luxury (or at least executive) motoring like their effortless acceleration and near-silent operation, so this new G60 5 Series has the potential to be the best yet in its ‘i5’ form.

But there are rivals, well-liked ones at that, which BMW must contend with to snatch the spot at the top of the large premium sedan ladder technically held currently by the Porsche Taycan in terms of sales - though Mercedes’ E-Class would lead if its electric cousin EQE’s sales were combined.

So, with names like that to go up against, BMW better have brought its A-game.

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.
