<And look at the A8 4.2 and BMW 740iL. The 740iL has a lot less bhp/ton
yet can move as almost fast. I wonder what's the story here?>
Well the A8 4.2 compared to the 740iL, in addition of the Quattro mechanism,
the A8 only has a 4 speed auto while the 740iL has the 5 speed auto.
The S6 estate compared to the BMW 328, even though they have the same bhp/ton
ratio, their torque numbers differ a lot, S6 (258 lb.ft) while 328
The new A4 2.8 compared to the BMW 328, the A4 is slower overall, even if the
A4 auto already has the new 5 speed auto box. The torque, I think has a lot
to do with the discrepancy.
Even the older 325 engine is much torquier than the Audi 2.8 V6.
