I'm noticing Hwy MPG at 40.4 and similiar Cd (equiv. for 520i).

"Sounds vaguely harsh" from 6,000 to 6,500 rpm red line.
2,600 rpm at 80 mph

"exceptionally quiet over expansion joints"

"terrific agility" steering, from 1.7 turns lock-to-lock, at Parking Lot
to 5.0 at 150 mph for more lelaxed detuned feeling, "utterly relaxed 120 mph"

Autocar's Peter Robinson said after driving the new 5,
"If I was given a new 530i with those options, and told this would be the only car I'd be allowed to drive for the rest of my life, I'd be a very happy man."
