Much like Mercedes-Benz and BMW put AMG and M badges on their respective performance models, Bentley grants its most potent vehicles the title of “Speed.” The title harkens back to the years between the First and Second World Wars, when W. O. Bentley built some of the meanest cars on the road. While the title might read rather strangely compared to its alphanumeric counterparts, there is perhaps no more apt a way to describe the vehicles than that. Take the all-new, 2013 Continental GT Speed for example.
