The Audi A6 was redesigned last year, getting a plush, well-detailed interior and advanced interface shared with the A7.
Its exterior is quite conservative, but there's a lot to love (including fuel efficiency) in its available supercharged V-6.
The latest BMW 5-Series has good handling and even more safety tech, while the Mercedes-Benz E-Class feels a little more forma--although in its latest versions it has sharper, quicker steering.
The Jaguar XJ can't be forgotten either; especially in 510-hp XFR form, it's almost exotic-quick while drawing looks from all kinds; but its tight backseat remains a major drawback.
Stronger performance and a sharper look make the Lexus GS 350, which was redesigned last year, a stronger contender, although it's not quite as responsive and balanced as the Infiniti M.
