The mighty GT’s fuel-economy ratings amount to just 11 mpg city, 18 mpg highway, and 14 mpg combined. That's a bit surprising for a 3.5-liter Ecoboost V-6 engine.
The Lamborghini Huracán with its 610-horsepower, naturally aspirated 5.2-liter V-10 engine returns 14/21/17 mpg. The Acura NSX, which has a similarly sized combustion engine that’s supplemented by hybrid technology rates at 21/22/21 mpg. It's a good thing those who are interested in buying the Ford GT aren't likely to be worried about the $ 400k car’s fuel economy.
