The Bentley Continental GT with the W12 is rated at 19.6 city/12.3 L/100km highway (12/19 mpg) on traditional premium, 29.4 city/16.8 L/100km highway (8/14 mpg) on E85, and easily less than that on an excited right foot. When we drove the Continental GT V8 at launch we were told that official U.S. EPA mileage could be rated as high as 9.8 L/100km (24 mpg) on the highway, and that, even with the right-foot factor, would be a generous improvement over the W12 for sacrificing just 67 horsepower and almost nothing in performance. It turns out Bentley told the truth, the official U.S. EPA numbers are 15.6 city/9.8 L/100km on the highway (15/24 mpg).
According to FuelEconomy.gov, the combined 19.6 L/100km (12 combined mpg) of the W12 is raised to a combined 15.6 L/100km (15 combined mpg) with the V8. Better yet, drivers will save about $1,000 loonies (with current exchange rate) on premium unleaded every year, the V8 needing just under CAD$3,400 worth of the explosive liquid, the W12 needing $4,300. On top of the fact that the V8 is roughly $18,000 less than the W12, with those annual savings you'll be able to add a couple more ties to your collection every year, or one bespoke shoe. Our advice? Start with the right foot – that's where the action is.
