$38,200 · Sedan

$47,500 · Sedan

Comparison Overview

Choosing between the refreshed 2025 Audi A3 and the highly anticipated 2026 BMW 3 Series often boils down to budget versus performance potential. The common dilemma is balancing premium brand cachet with immediate running costs. The A3 undercuts the BMW significantly, starting at $38,200 compared to the 3 Series' $47,500 MSRP—a difference of $9,300. While the A3 is efficient, achieving 28 MPG combined on regular unleaded, the larger 3 Series nudges slightly ahead with 31 MPG combined, though it demands premium fuel. Power output shows the 3 Series dominating, delivering 255 hp versus the A3's 201 hp, resulting in a 54 hp gap. However, the A3’s smaller footprint (177.3 inches long) makes it more agile in dense city environments, while the BMW offers double the cargo space at 16.9 cu ft versus the Audi's 8.3 cu ft.
