2025 Audi S4 vs 2025 Porsche 718 Cayman
Comparison Overview
Deciding between sensible performance and pure driving focus often centers on budget and practicality; that’s the dilemma facing potential buyers of the 2025 Audi S4 and the 2025 Porsche 718 Cayman. The Audi S4 leads on raw output, boasting 349 hp and 369 lb-ft of torque from its all-wheel-drive sedan body, making it a superior year-round choice with 20 cu ft more passenger space available (though cargo is slightly less at 12 cu ft vs. 15 cu ft). However, the Cayman is substantially cheaper in terms of usability, demanding a $17,900 higher MSRP of $72,800 compared to the S4’s $54,900. While both manage a nearly identical 24 MPG combined, the S4 offers a more conventional 4-door layout, whereas the mid-engined Cayman prioritizes handling dynamics over passenger capacity.

The Audi S4 has a clear advantage in brute force, producing 349 hp compared to the Cayman's 300 hp. While the S4 has more torque (369 lb-ft vs. 280 lb-ft), specific 0-60 mph times would determine the true acceleration winner.
Which car will be more expensive to run daily?
Both cars share an identical 24 MPG combined fuel economy rating. However, the S4 requires 'premium unleaded (recommended),' whereas the Cayman requires premium fuel, potentially leading to higher mandatory fueling costs.
How do the physical sizes compare for parking ease?
The Porsche 718 Cayman is significantly smaller overall; it is over 5 inches shorter in length (172.4 inches vs. 187.5 inches) and over an inch lower (51.0 inches vs. 56.2 inches), making it slightly easier to tuck into tight spots.
Is the Cayman's smaller cargo area manageable?

Yes, the S4 uses a traditional 8-speed shiftable automatic offering standard automatic convenience, while the Cayman utilizes a 7-speed automated manual focused on faster shifts for performance driving, catering to different driver preferences.
How does the purchase price impact overall value?
The $17,900 price difference heavily skews value toward the S4, which costs $54,900. You must determine if the driving engagement of the $72,800 Cayman justifies paying nearly 33% more upfront.
