Coming hot on the heels of our recent test of the M5, our brief time with the 2006 BMW M6 was especially enjoyable as we had already learned enough of the Sequential Manual Gearbox's behavior to really tap into the M6's performance. The same basic drivetrain powers both cars: an operatic 500-horsepower 5-liter V10 engine coupled to the seven-speed SMG. Performance in both cars is startling but kept doable with stability control, adjustable damping, and numerous engine and transmissions modes. The M5 actually has the better drag coefficient of the two, but the M6 evens out any performance edge with a slight weight advantage.
