2026 Audi RS 3 vs 2026 Genesis G80

$66,100 · Sedan

$58,450 · Sedan

Comparison Overview

Choosing between speed and space often trips up buyers looking at these two compelling German and Korean sedans. If maximizing thrills on a budget is the goal, the 2026 Audi RS 3 is the obvious choice, packing a hefty 394 hp while commanding a higher $66,100 MSRP. Conversely, the 2026 Genesis G80 offers significantly more practicality; it boasts a generous 13.1 cu ft of cargo space compared to the RS 3's meager 8.3 cu ft, and saves you $7,650 upfront. The trade-off for this extra space and lower entry cost is performance, as the G80 offers 300 hp against the Audi’s output. While the Audi's combined 23 MPG is decent for performance, potential owners must weigh the mandatory premium fuel against the G80’s 'recommended' premium fuel strategy. The RS 3 is the sharper tool, but the G80 is the clear overall better daily driver for most.
