Gorgeous exterior, lavish interior, and a hefty price tag are all things you can expect from the Bentley Continental GT Speed. This stunning ride has a twin-turbo 6.0 liter W-12 engine under the hood that produces 626 horsepower and 607 lb-ft of torque. The transmission is an eight-speed automatic with a manual shifting mode. Due to the Continentals burly motor, the vehicle has poor gas mileage. The EPA estimates the Bentley Continental GT Speed gets a dismal 13 mpg city and 23 mpg city. Any cares you have about gas mileage will melt away once you start driving this amazing machine. The suspension is perfectly tuned, making the Continental GT very agile when changing lanes or makes hard turns, and the throttle responds quickly when you want to blast down straightaways.
