PTV is purely software. can we have our .1 cars updated with this software ?

PTV....

Porsche Torque Vectoring (PTV).
Porsche Torque Vectoring (standard
on 911 Turbo S models,
optional for 911 Turbo models),
with variable torque distribution
to the rear wheels and a mechanical
limited-slip rear differential,
is a system that actively enhances
vehicle dynamics and stability.
As a function of steering angle
and steering speed, accelerator
pedal position, yaw rate and
vehicle speed, PTV is able to
improve steering response and
steering precision significantly
by specific braking of the right or
left rear wheel.

In simple terms, this means that
when the car is driven assertively
into a corner, moderate brake
pressure is applied to the inside
rear wheel. Consequently, excess
drive force, which varies depending
on the braking force applied
to the inside rear wheel, can be
distributed to the outside rear
wheel, and a rotational pulse (yaw
movement) is generated around
the vehicle’s vertical axis. This
assists the steering input and
results in a more assured steering
manoeuvre(sic).

At low and medium vehicle
speeds, the system significantly
increases agility and steering
precision, whilst at high speeds,
and in combination with the
mechanical limited-slip differential,
it additionally ensures greater
driving stability.
The system, combined with
Porsche Traction Management
(PTM) and Porsche Stability
Management (PSM), also puts
its stabilising (sic) effect to good use
on road surfaces with varying
levels of grip and on snow and ice.
As PTV increases the car’s
dynamic performance, the system
remains active when driving
on the racetrack, even if PSM
has been deactivated.
Where efficiency
is concerned,
this enhanced performance and
stability are achieved without the
need for any additional components,
apart from the mechanical
limited-slip rear differential. In
other words, a more enjoyable
drive with no additional weight.

 

It is on the list of factory options when my VIN was pulled before I bought the car. Mind you they listed it as a Cayman........

 

good question.

and expanding...anything software related that improves each generation, you think could be offered as later upgrades to the earlier cars. maybe a few new silicon chips would need to be part of the upgrade, but still. I bet there's a decent market for these types of upgrades...we would pay for them.

 

mclaren is doing it for free to their mp4 clients. free chip upgrades for the early model mp4s. (MY2013 has higher boost than '12 the mclaren has torque vectoring too. just sayin'.

theres gotta be a way to get this on our cars if porsche wont do it for us..

 

It only came with the Limited Slip Diff, so you would need to fit that as well. It would probably mess up the control units calculations otherwise.

 

ME 7.8.1 versus SDI3. I don't think the software will port over.
