Gas mileage might be the furthest thing from the minds of Bentley drivers, but at least engineers have spent some time wringing more miles per gallon from its estimable engine.
The Flying Spur stands by its unusual powerplant, a signature twelve-cylinder with the pistons arranged not in a "vee," but in a "W" layout. Maybe it's a subtle homage to the parent company--but Bentley says the unconventionally engineered piece is a hallmark of the brand. It's the only engine offered in the Spur, whereas the bigger Mulsanne sports a twin-turbo V-8.
It's by no means the most efficient choice, but it compensates with massive torque and heartening acceleration. And this year's EPA ratings for the Flying Spur are better; the sedan's lost 110 pounds, and gained a new eight-speed automatic. Both of those improvements net the sedan a slight gain on the EPA cycle, to 12 miles per gallon city, 20 mpg highway, and 15 mpg combined.
We've heard rumblings of diesel and hybrid powertrains spreading across the VW Group even to its most prestigious brands, but as of yet, the Bentley Flying Spur is unworried.
