Autoweek on quattro

["R. Dunbar" <rbd@vnet.net>]

Autoweek, April 6, page 13, says this about the Audi A8:

"...The aluminum A8 costs substantially more than the other two German
sedans [M-B E430 & BMW 540i]. But is it worth it? On dry pavement, no. The
extra weight of the quattro system translates into less-snappy acceleration
and a rougher ride. On snow, or rain-slick pavement, the A8 would no doubt
outperform the other two..."

Are these remarks about the quattro system's "less-snappy acceleration and
a rougher ride" on dry pavement correct? I'm about to order my first Audi
and would like to avoid a mistake.
