It's the Mazda6 , which the company says is all new from stem to stern and top to bottom – and which surely looks and feels that way. In fact, so far as its looks are concerned, I think this is one of the best-looking sedans on the road today, sporty and modern and lovely to behold. And that's saying something; I thought the previous 6 was one of the nicest styling jobs around, yet park it next to the fresh 6 and the previous generation looks positively frumpy.
