2025 BMW M4 CS vs 2026 Audi RS 7

$123,500 · Coupe

$132,700 · Sedan

Comparison Overview

Choosing between the razor-sharp focus of the 2025 BMW M4 CS and the immense, muscular practicality of the 2026 Audi RS 7 presents a classic performance dilemma: handling purity versus brute-force space. The Audi RS 7 carries a higher initial investment at $132,700 compared to the M4 CS's $123,500 price tag, but it compensates with a staggering 621 hp and 627 lb-ft of torque, easily outclassing the M4 CS's 543 hp. While both utilize AWD and an 8-speed automatic, the M4 CS aims for agility with its smaller dimensions (189.0 inches long) and slightly better efficiency (18 combined MPG). However, if utility is a concern, the RS 7 offers nearly double the cargo capacity at 24.6 cu ft versus the BMW's 12 cu ft. Ultimately, buyers must decide if the BMW's track-ready dynamics justify foregoing the Audi's significant power and size advantages.
