Technology of the Year
Porsche Active Ride
As car makers
turn their attention away from ICE, innovations in powertrain
technology dry up. Meanwhile, progress on battery technology is steady
but undramatic, at least until solid state battery enter production
(whose roll-out is pushed back yet again, to probably the end of this
decade). This means at the meantime the most promising development is
found at the suspension department. Following last year's winner
Multimatic TASV damper (used in Ferrari Purosangue and F80), this year
Porsche Active Ride takes the top honour.
Developed in conjunction with ZF, PAR consists of an air spring, a
twin-valve adaptive damper and a motor-driven hydraulic pump in each
suspension. The latter can pump oil into either the compression chamber
or expansion chamber of the damper, pushing the suspension up or
pulling it down at lightning speed. Moreover, it can exert a force up
to 1000 kg to each damper, easily countering the weight and momentum of
the car. As all 4 wheels can be independently controlled, the car may
glide over bumps with very little body movement, or corner quickly yet
flatly, or brake without dive. Ride height can be adjusted according to
speed or drive mode, too. It has the ride and handling of the new
Panamera transformed.
