A feature of this months issue of "Auto Motor und Sport" is a winter handling comparison between the Lexus LS600h, Mercedes C320 CDI 4Matic and six other automobiles. We at Newsbot have focused on the Lexus and Mercedes.
We begin with the LS600h, which has a very simple and conventional AWD systems design with certain features that could have been copied from Audi's revolutionary Quattro system: a central torsion distributor and limited slip differential with a bias towards rear power distribution (40f:60r). Nevertheless the immense weight of the LS600h means it handles poorly on snow and its AWD system is useless in helping it out. Furthermore, the ESP annoyingly intervenes too often and in some cases makes a bad situation even worse.
The Mercedes C320 CDI weighs less than the Lexus, is itself a heavy a car though. The 4Matic system works with a power distribution of 45f:55r. Power to both front and rear wheels is channeled through a central differential. Individual wheels of the Mercedes can be either accelerated or braked by the computer allowing for quick trajectory changes and control to be restored. The C320 CDI handles brilliantly on snow.
