2025 Aston Martin DB12 vs 2025 Porsche 911
Comparison Overview
Deciding between the 2025 Aston Martin DB12 and the 2025 Porsche 911 boils down to where you draw the line between opulent presence and surgical precision. If headline-grabbing power is key, the DB12 boasts a commanding 671 hp, eclipsing the 911's 388 hp output, justifying its $245,000 MSRP. However, the practical realities hit hard: the DB12 delivers only 17 combined MPG compared to the 911's more frugal 21 combined MPG. This nearly $125,000 price disparity, coupled with a significant 4 MPG efficiency gap, means the 911 remains the sensible, albeit still thrilling, choice for most drivers who plan on using their coupe frequently. While the Aston offers brute force, the Porsche delivers refined daily usability wrapped in a much more accessible package.
