it is amazingh that car and driver got to 60 in 3.9 seconds, when nobody, as far
as i know has gotten in the 3's with the lighter ore harder/racier 63 black
seres?
is there any reason that most german cars are STILL limted to 155?? i mean threy
have the technology for the tyres,brakes,transssinon and stuff lke that, so
why?? i mean they do ave the autobahn, whichis about 40%unristricted, and
countrys lke the uk and us dont have autobahs and they dont limit tere cars,
(well some)...(assholes..lol) so i jst dont see the point??
the 155mph limit is a gentleman agreement between Audi BMW and Mercedes.. in the
past it was set because the tire technology could not keep up with possible
topspeed of their supersedans, today it is more a green limit... all three offer
unlimit as option for their models.
BTW much more than 40% of the Autobahn is unrestriced... I would say 80% are
unrestriced and 20% are partly restriced by road construction and electronic
road signs... the rest are speed limits at large Autoban crossings with many on
off ramps or speed limits because of noise reduction in urban areas.. The next
Autobahn is 1mile away from my home... and it is unlimited but has electronic
sights for rush hour traffic...
why do they limit some of there cares and not all of them?? hence they limit the
sl65 to 155, but in reality it will hit around 206 orso, and yet the dont limit
the slr which hits 208, and yet agai the black series 65 and with the dtm amg
which are both limited to 200, and they can go over 205, so i dont see a point
in giving a car 525 bhp (sl63) and than limiting the speed. and im not sure what
you mean by (Green Limit)??
1/4 mile 12.3s ........ 0-160km/h 9.3s .......weight distirbution 54/46%
