Audi S4 vs BYD Atto 1

What's the difference?

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.

Back in 2010, Mitsubishi released Australia’s first mainstream electric vehicle (EV) in nearly a century.

That model, the i-MiEV, was a four-seater city-sized Kei car from Japan that cost $48,800, before on-road costs, or from roughly $70,000 in today's money. Little wonder it bombed. That was four times more than petrol-powered equivalents of the time.

Now, in 2026, the new BYD Atto 1 is the first EV sold here since the i-MiEV’s 2013 departure to be considered a four-seater city car.

It’s also the least-expensive EV money can buy, being even cheaper than many internal-combustion engine alternatives like the Mazda 2 and Toyota Yaris hybrid. The fact is, there’s nothing remotely near the Chinese supermini’s base price that’s electric.

But is the Atto 1 any good?
