Evo issue - 286 out now:
"Other dynamic aspects of the E63 contrast with the M5, too. I often find the steering of AMGs a fraction too heavy, and frustratingly it’s one of the few characteristics that you can’t adjust in the set-up menu. But after a couple of stints at the wheel, I found myself preferring the E63’s weighting and ended up switching the steering on the M5 from Comfort to the weightier Sport, just to calm things down a little. And although the BMW’s optional carbon-ceramic brakes probably offer more endurance, especially if you’re tempted to venture onto a track, I prefer the softer, less abrupt step-in of the Mercedes’ iron discs."
"Meanwhile, with dry asphalt under its wheels, the M5 just gets better, that firmer Competition chassis coming into its own. Knowing how it felt from the off, this is expected, and while the M5 doesn’t exactly shrink around you, it feels the lighter, more agile and more exciting car. In the right circumstances you can still play with the odd powerslide, too, though just as in the wet, all aids are off so you need to know what you’re about. This E63 rides better and has more composure than the estate we drove a year ago but there’s no question that the BMW is the sharper tool for dissecting a road, offering more steering feedback and precision, more connection with the road. That said, the E63 still has the grip and pace to peg the M5."

It sounded like they enjoyed driving both cars in rear-wheel drive mode and it was clear the E63 S was the more comfortable super saloon, while the M5 Competition the more engaging to drive.
