2025 Audi RS 7 vs 2025 BMW M4 CS
Comparison Overview
Deciding between the 2025 Audi RS 7 and the 2025 BMW M4 CS often boils down to prioritizing usable space versus raw power in a high-performance package. The RS 7 demands a $5,100 premium over the M4 CS, starting at $128,600, but it delivers significantly more punch with 621 hp compared to the M4 CS’s 543 hp. This power difference translates to superior straight-line performance from the Audi. However, the RS 7’s practicality shines with 24.6 cu ft of cargo space, dwarfing the M4 CS’s mere 12 cu ft, which is a critical consideration for daily usability. While both vehicles require premium fuel, the slightly better efficiency of the M4 CS (18 combined MPG vs. the RS 7's 17 combined MPG) offers minimal long-term savings. The RS 7’s longer body (197.2 inches vs. 189.0 inches) contributes to its more spacious sedan layout.
