BMW M3 Sedan Road-Testing

BMW hasn't released any information yet on what will power their new M3 sedan, however we can guess that a performance-oriented V8 will be a viable option for the German automaker rather than something like an inline 6-cylinder affixed with a turbocharged.Even a tri-turbocharged inline-6 doesn't seem likely, however that has been heard around the CarBuzz watercooler.Rumors of a 3.3-liter twin-turbo V6 engine delivering 450 hp has also been heard.The BMW M3 sedan should weigh in a bit lighter which can only bode well for performance. Our spy photographers waxed poetically on its wider fenders, so we will wait and see what the aesthetically-pleasing new M3 sedan will use as motivation.Check out our spy photographer's work as the BMW M3 sedan does some real-world testing on the road.Photos: CarPix
