$79,900 · Hatchback

$63,900 · Sedan

Comparison Overview

The eternal question when upgrading your daily driver is balancing thrilling performance against sensible ownership costs. Looking at the 2025 Audi RS 5 ($79,900) and the 2026 Mercedes-Benz E-Class ($63,900), we see a clear divergence in philosophy. The Audi is the clear performance choice, boasting 444 hp and 442 lb-ft of torque, letting you devour miles quickly with its All-Wheel Drive system. However, this speed comes at a cost: the RS 5 manages only 20 MPG combined and requires premium fuel. Conversely, the E-Class, priced $16,000 less, is significantly thriftier, achieving 28 MPG combined. While the E-Class offers less punch at 255 hp, its longer 194.9-inch body and better efficiency make it the pragmatic choice, despite having less cargo space (12.7 cu ft vs. the RS 5's 21.8 cu ft hatchback capacity).
