RE: bmep (was:Top Gear: The TT article)

[Eaton Dave <dave.eaton@minedu.govt.nz>]

not sure why you're equating bmep wth engine stress.  they're not the same
thing, or even generally related.  wrt stress, the i5 is also undersquare so
high piston speeds are not exceptional.

high static cr on an audi turbo engine also isn't new.  the high po 165kw
1.8t app is a 8.9 to 1 cr (not 9:1).  the 3b/rr/a(x)u turbo motors are all
9:3 to 1 with a simlar bmep figure.  the highest po apps of this engine
(with full warranty) have higher bmep's again (the adu has a 9:1 cr).  also,
the 1800cc turbo has been touted to 400hp in high po tuner apps (mtm).

also, despite claims to the contrary, the haldex may not be active.
implementation details are few and far between, but certainly, in its
standard config, the haldex could not be described as "full-time awd", any
more than a simple vc could.  audi's implementation is unknown at this
stage.

autocar tested the ttq and loved it.  then they got peter robinson to test
back-to-back with a boxster.  came 2nd.  not convincingly, but 2nd
nevertheless.

oh, and peter robinson owns a boxster.  disclaimer?  not likely.
