A look at Cadillac future products

General Motors has green-lighted the development of a large flagship sedan for Cadillac, sources say, part of its plan to position its luxury brand's lineup to take on the German luxury stalwarts in every key sedan segment.

This One-77 was taking part in a supercar run from London to Silverstone on Friday to promote the FIA GT1 World Championship which takes place this weekend at the new Silverstone track, and was the first chance to see the One-77 both on the move and away from a static display at an event. We’ve seen the One-77 in the flesh a couple of times, but each time it’s been the same car (the AM One-77 from Salon Prive last year) but this is a different car.
