This Bilstein-engineered system, which borrows from Porsche 959 and Lotus Formula 1 technology, uses a gas-over-oil shock absorber whose hollow center shaft is fit-ted with an adjustable orifice that allows varying amounts of shock oil to be bled off from around the piston. This provides six levels of damping in each of the three modes. Touring, Sport, and Performance, for a total of 14 steps (not 18, because some overlap). Settings range from very...
