My experience with Audi RS3 Vs. BMW M3

I kicked off 2025 craving a performance car, landing on the Audi RS3 and BMW M3 after test drives galore.

I picked up the RS3 for $63,500 on January 5 and the M3 for $78,200 on January 7, hitting the road with the RS3 on January 10 and the M3 on January 12 after a quick tune-up.

The RS3’s Virtual Cockpit and snug RS seats grabbed me on January 10, though its cargo space struggled with my gym bag.

The M3’s iDrive 8 and roomier cabin impressed me on January 12, but its fuel thirst hit hard on a long haul.

By February 15, the RS3’s Quattro AWD mastered icy streets, while the M3’s xDrive tackled a snowy track with gusto. On March 20, a highway blast showed the RS3’s 22/29 MPG edge, though the M3’s raw power pulled ahead.

April 10 brought a spirited drive; the RS3’s agility shone on twisty roads, but the M3’s third gear launch thrilled on straights. By May 15, after a rainy commute, the RS3’s quieter cabin stood out, while the M3’s handling dominated on June 5.

As of 11:52 PM +06 on July 18, 2025, after 180 days, both deliver excitement, with the RS3 excelling in practicality and the M3 in outright performance. You’ll see their strengths align with your driving style, so let’s explore!
