Sport Plus and Winter Driving
To those of you that have Sport Plus mode, do you think it's various monitoring functions make winter driving any safer or controlled? Was curious about this as I was ploughing home through deep snow tonight.

Probably not...the normal mode is probably the safest given the lighter throttle response discouraging higher speeds. The Sport Plus with firmer dampers and heavier steering isn't going to help. The adaptive dampers are doing their thing in all modes and have a higher allowable range in normal, meaning on rough surfaces they should track the surface better.

I have the shop and feature manuals for the 2016 NX 200t. There's full descriptions of how everything works in the feature manuals. The AVS suspension is fed by a ton of different systems, it's pretty neat.

@batchelor. From my experience with Lexus vehicles including the NX, Sport S+ will also allow for a less intrusive traction/VSC control over Normal/Eco modes, but not by much of a difference TBH. If the car senses you're sliding beyond your steering input, it will still try to correct the motion towards the intended direction within the confines of the laws of physics of course.
Nice graph! Always wondered what the curves looked like.
Indeed! Here's the list of systems posted here https://www.clublexus.com/forums/nx-...ml#post9292230

Adaptive Variable Suspension
The NX 200t F Sport is available with an optional new-generation, linear
solenoid-type Adaptive Variable Suspension. Working in conjunction with
Drive Mode Select (which adds Sport+ mode), it automatically adjusts
suspension damping in all driving conditions to achieve the highest possible
straight line ride comfort and high-speed stability, with suppression of body
roll and better cornering agility.
Lexus’s breakthrough of using linear solenoid actuators in place of the
more conventional step motors more than trebles the number of control
force levels – from nine to 30. The actuator is more compact, too, so it has
been possible to relocate it from the top of the damper unit to its lower side,
creating a lower bonnet line and more load space. As a result, suspension
response time has decreased four-fold, from 80 to 20 milliseconds.
AVS operation is governed by nine control inputs:
• Vehicle Speed Sensing Control gives ride comfort at low speeds and
handling stability at higher speeds
• Roll Attitude Control maintains the optimum vehicle attitude during
cornering
• Anti-dive Control moderates the tendency to pitch forward under braking
• Rebound Control works best on rough surfaces, smoothing out bumps
• Ruggedness Sensing Control decreases damping force when vibration
from uneven road surfaces is sensed
• Unsprung Mass Variation Damping Control increases damping force
when components such as the wheels start to resonate on uneven surfaces
• VSC Co-operative Control works with the vehicle stability control
systems to provide the best handling options when the vehicle starts to
skid, for example on a damp surface
• Pre-Crash Safety System Co-operative Control provides extra damping
force for accident avoidance under heavy braking

Did some searching, nothing indicates that Sport or Sport S+ will change how the traction and VSC systems behave. This is the system diagram but none of the VSC/Trac descriptions indicate influence from the driving mode selector.

One other interesting tidbit of info...not totally related but...
When using full "M" mode, the transmission shifts quicker than any other mode (including/independent to being in Sport or Sport S+) and locks up the torque converter in 2nd gear and higher so that output is direct (like in a manual). So if you want fastest shift times and the most throttle response, you have to be in "M" to get it.

Interesting. I'll have to retest this from my butt dyno now that we got a major snow storm in!
