BMW katsetab taas nelikroolimist

[priitv8]

Kõik ju mäletavad veel iisaku E31 nelja ratta roolimist?
Paistab, et asi on koos Continentaliga uuesti käsile võetud.

imho, likvideerigu enne see roolilati viga ära uuematel BMW'del ja siis hakaku asju veel juurde mõtlema mis lagunevad ja hingehinda maksavad!!

muidu kindlasti tore asi ja juhitavusele mõjub kõike muud kui halvasti!

Saksamaal ei lagune BMW sedasi, seega ei koti see neid.

The hydraulic four-wheel-steering
Maybe what makes the 850CSi most special was the Active Rear-Axle Kinematics system which was standard on all Euro CSis. It's abbreviation (AHK) is the abbreviation of the german expression for it (Aktive Hinterachs-Kinematik). While normal passively steering rear axles allow the wheels to be slightly turned by the forces acting on them when cornering, the hydraulics of the AHK turns in the rear wheels before those forces build up. The AHK is therefore a real for-wheel-steering system!
From a speed of about 60 kph (37 mph, BMW doesn't disclose the correct numbers) and up, a computer controlled hydraulic system steers the rear wheels depending on the turn angle of the front wheels. All four wheels then turn into the same direction, minimize weight shifts (the CSi weighing almost two tons even beats Turbo-Porsches in lane change maneouvers) and even allow steering adjustment in a curve to an extent that would inevitably cause you to crash in any other car. According to various sources the maximum angle the rear wheels turn is between 1.5 and 2.5 degrees (again, BMW doesn't tell).

With the introduction of the CSi the Active Rear-Axle Kinematic was also on the option list for the normal 8 series. But the additional amount of money you had to pay was 6400 Euros (DEM 12500), so a non-CSi with AHK will belong to the rarest things on this planet.
