The Vantage has 2.7 gallons more fuel capacity than the 911’s standard fuel tank (19.3 vs. 16.6 gallons), for longer range between fill-ups.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Aston Martin Vantage higher (5 out of 10) than the Porsche 911 (4). This means the Vantage produces up to 5.2 pounds less smog-producing pollutants than the 911 every 15,000 miles.

The Vantage’s 275/35R21 front and 325/30R21 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the 911 Dakar’s standard 45 series front and 40 series rear tires.
