Comparison Overview

Deciding between a sleek coupe like the 2025 BMW 8 Series and a stately sedan like the 2026 Audi A8 often comes down to prioritizing style versus supreme usability. While both vehicles share an identical 335 horsepower and 369 lb-ft of torque, their execution differs significantly. The BMW 8 Series boasts a superior fuel economy rating of 24 combined MPG versus the Audi A8's 22 combined MPG, meaning fewer stops at the premium unleaded pump.
