The hyper hatchback market has taken an interesting turn as the Mercedes-AMG A45 S is joined by the brand-new 2022 Audi RS3 Sportback. In this quick comparison, we look at performance, options, practicality and of course, price.
Since its launch locally back in August 2020, the Mercedes-AMG A45 S has had the segment to itself. Nothing in the hatchback segment could come close to matching its 310 kW output or hefty price tag. In September 2022, Audi South Africa announced specifications and pricing for its brand-new Audi RS3 Sportback and Sedan. With all details available, its clear to see Ingolstadt’s offering is positioned to give the Mercedes-AMG A45 S a run for its money.
In this comparison piece between Mercedes-AMG A45 S vs Audi RS3 Sportback, we crunch the engine outputs and claimed performance, compare the dimensions and practicality aspects, and measure value by seeing how much you’ll have to pay for optional extras.

It’s remarkable to see what AMG has achieved with that 2.0-litre 4-cylinder engine in terms of performance and outputs, while offering a 2-year/unlimited kilometre warranty. Remember it’s easy to make big power, but to do so reliably? Impressive.
Audi’s RS3 Sportback may be a bit down on power in comparison to the AMG, but it is fractionally lighter and delivers maximum torque earlier in the rev range, which gives it a slight advantage when it comes to straight-line sprints from standstill. We look forward to putting the two vehicles in a head-to-head drag race to settle the debate between Mercedes-AMG A45 S vs Audi RS3 Sportback.
