The M5 has spawned some serious competition from excellent luxury brands.
The M5’s closest rival, the Mercedes-AMG E63 sedan, offers even more luxury and space, has stupendous power, and now delivers handling that it hasn’t in the past.
The Cadillac CTS-V is raucous fun, but it trails the BMW in refinement.
Audi’s S6, soon to be replaced, isn’t as much of a track star as the competition, but it has always been sophisticated and it may have made BMW turn to all-wheel drive.
The Lexus GS F performs well on a track thanks to its torque vectoring rear end, and it offers plenty of luxury, too.
