Aston Martin Vanquish MPG: 5 Tips To Improve Fuel Economy

The Aston Martin Vanquish from 2014 to 2018 stands as a pinnacle of British grand touring excellence, powered by a mighty 6.0-litre V12 engine. While its exhilarating performance defines it, fuel economy remains a key concern for owners. Official figures promise around 21-28 mpg on the highway, but real-world results vary widely based on driving style and conditions.

Official Fuel Consumption Ratings

Manufacturers provide standardized MPG estimates that set expectations for the Vanquish. For the UK market, the combined cycle yields 21.4 mpg for early models, improving slightly post-2014 updates to 22.1 mpg with the eight-speed transmission. US EPA ratings list 15 mpg combined, 12 city, and 18 highway for the 2014 model. These numbers reflect lab conditions, often optimistic compared to daily use.

These ratings stem from NEDC tests in Europe, known for leniency before WLTP adoption. Post-2014 chassis tweaks, including stiffer suspension and launch control, prioritized dynamics over efficiency.

Real-World MPG Experiences from Owners

Owners report 15-25 mpg in mixed driving, dropping to 10-12 mpg during spirited runs. Highway cruising at 70 mph can hit 28 mpg, but urban stop-start slashes it to single digits. One long-term test logged 18.5 mpg over 10,000 miles, praising the V12’s smoothness despite thirst. Factors like tire choice and weight (over 1,700 kg) influence results.

• Motorway cruising: Up to 28 mpg at steady 70 mph.
• Mixed daily driving: 18-22 mpg average.
• Aggressive acceleration: 10-14 mpg, especially with launch control.

Convertible Volante variants fare slightly worse due to added mass, around 1-2 mpg less.

Factors Affecting Fuel Efficiency

Several elements dictate the Vanquish’s economy. The 6.0-litre V12, outputting 565-568 bhp, demands premium fuel and guzzles under load. Rear-wheel drive and carbon-ceramic brakes enhance stopping power but not frugality.

Transmission Impact

The shift from six-speed to eight-speed auto in 2015 boosted highway efficiency by enabling lower revs. Paddle shifters allow manual control, but auto mode optimizes shifts for better mpg.

Weight and Aerodynamics

Aluminum and carbon fiber construction keeps curb weight manageable, aiding glide on open roads. Sleek lines minimize drag, crucial at supercar speeds.

Driving Mode Choices

GT mode prioritizes comfort and economy, while Sport and Track unleash power at efficiency’s expense. Dynamic Stability Control aids traction without excess fuel burn.

Tips to Maximize MPG in Your Vanquish

Owners can stretch fuel further with smart habits:

1. Smooth acceleration: Avoid launch control; build speed gradually for 20% better economy.
2. Highway focus: Maintain 65-75 mph for peak efficiency.
3. Tire maintenance: Keep pressures optimal; low-profile rubber wears fast but affects drag.
4. Light loads: The 2+2 setup tempts passengers; solo drives save fuel.
5. Regular servicing: Clean air filters and fresh oil preserve V12 efficiency.

Premium unleaded (98 RON) is mandatory; cheaper fuel hampers performance and economy.

Running Costs Beyond Fuel

At £300,000 new, Vanquish ownership extends beyond MPG. Annual fuel for 10,000 miles at 20 mpg costs £2,500+ (UK prices). Insurance groups it high (50/50), and tires (£1,000/set) plus brakes (£5,000) add up. Reliability improved over predecessors, with proven V12 and ZF gearbox.

Vanquish vs Rivals: MPG Comparison

The Vanquish slots between Bentley’s Continental GT (18 mpg combined) and Ferrari F12 (20 mpg). McLaren 650S edges ahead at 22 mpg thanks to turbocharging.

• Bentley Continental GT: 18 mpg, more luxurious but heavier.
• Ferrari F12: 20 mpg, sharper but harsher ride.
• Porsche 911 Turbo: 25 mpg, turbo efficiency winner.

Aston’s naturally aspirated V12 trades mpg for character.

Performance and Economy Balance

Zero-to-60 in 4.2 seconds belies modest mpg. The eight-speed holds gears longer, blending grunt with usability. Owners value the exhaust symphony over sips-per-mile.

Long-Term Ownership Insights

Used prices start at £100,000 for low-mileage examples. Fuel remains 20-30% of costs, but prestige endures. Improved electrics reduce downtime. Volante appeals for open-air drives, at slight efficiency penalty.
