the same book
lists torque for the us 6.9 as 360. weight 4300, axle 2.65, three speed automatic, no hp listed. again 0 to 60: 8 sec. top end 140.
the 560 shows 238 hp (us) 287 torque, 2.47 rear end, four speed automatic, 0 to 60: 7.4, weight 4125, top end 140.
so even though the 6.9 has a lot more torque, with more weight and less gears to work with is a bit slower to 60 with the same top end.
i have never driven either, but would enjoy the opportunity to do both.
my 500sec is pretty satisfying to drive and it has only 185 hp and 247 torque.
best i suspect would be a euro 6.9. a euro 5.6 would i am sure be very nice too. i have driven a euro 500sel. it was noticably quicker than my sec even though the sel weighs 200 # more and has a 224 rear end instead of 247.
