Porsche Torque Vectoring (PTV) is the ideal complement to the conventional Porsche Stability Management in terms of driving dynamics and driving stability (PSM). There are two variations of the system: using a manual transmission, as PTV with a mechanical differential lock, and for PDK vehicles, as PTV Plus with an electronically controlled, completely variable differential lock To improve the vehicle’s steering behavior and precision during highly dynamic driving, the system essentially uses targeted braking interventions on the inner rear wheel. It has many benefits, particularly when turning around curves. When the driver begins to steer, the inside rear wheel is selectively braked. This indicates that the outside rear wheel has a greater drive torque than the inside wheel. The car experiences a yaw moment due to the difference in torque, which supports the steering even more. The outcome? Significantly better steering behavior and handling. Additionally, PTV Plus uses the differential lock strategically to give a considerably higher level of traction when accelerating out of curves.

Explained: Porsche Torque Vectoring (PTV) Plus
We use Porsche’s own materials whenever possible to assist explain some of their more complicated technology. This week, Porsche unveiled a series of movies outlining the advantages of each of its numerous chassis control technology. PTV Plus, or Porsche Torque Vectoring Plus, operates by automatically applying brakes to the inside rear wheel during a turn and locking the rear wheel differential to come out of the turn. Watch the video below to see it in action and gain a better idea.
Check out this post to see how a 911 with simply PTV compares to two other 911s (one with PTV and Sport Chrono and one with PTV, Sport Chrono, and PDCC).
You have choices, third section: Porsche Torque Vectoring
You’ve decided on the Porsche you want to purchase, but you’re not sure which performance-enhancing features to look for. The fact that many of the most well-liked and practical factory performance modifications, such as ceramic composite brakes, electronic anti-roll bars, and air suspension, are extremely expensive adds to the difficulty of the situation. How can you tell which choices are best for you?
When you arrive at the dealership to take a test drive, be ready: Become informed. Knowing what you need and what you desire depends on your understanding of the functioning of the many optional pieces of equipment. If you are clear on what you need in a Porsche, you can specify the model that best suits your needs while remaining within your price range. To assist you, we’ve compiled a list of the five performance options that we believe offer the best value for the money, along with information on their costs and functions. We discussed Porsche Dynamic Chassis Control last week. In the upcoming weeks, we’ll release the remainder. Remain tuned!
Why are limited-slip differentials in new Porsches no longer mentioned? due to the dominance of torque-vectoring systems. When a wheel slips, a limited-slip differential responds by transferring torque to the driven tire with more traction (in a turn, for example). A torque vectoring system does the same thing, but it also brakes the inside rear wheel as soon as you enter a corner to aid in turning in. As a result, there is little to no unintentional understeer or oversteer and a sharp turn entry and stable corner departure. Without the PTV or PTV Plus upgrades, a Porsche will have an open differential, which reduces traction and stability by not transferring torque to the driven tire with better traction.
The differential lock’s mechanical versus electronic operation is the primary distinction between PTV and PTV Plus. The torque distribution of PTV Plus is indefinitely flexible due to the electronically controlled diff lock, making it more dynamically capable than PTV, which is dependent on a mechanical limited-slip differential. Because torque vectoring greatly improves handling, all of our experiences with it have been positive. However, unless you’ve driven the identical car without torque vectoring, you might not notice the difference it makes.
Because it mostly depends on the model in issue and its transmission, choosing a torque-vectoring system for each Porsche model might be perplexing for clients. So, for each of Porsche’s models, we’ve compiled the option combinations needed to acquire PTV or PTV Plus (where appropriate). The transmission determines whether you can choose PTV or PTV Plus in the new 911 system. PTV is the only choice if you choose the manual gearbox; PTV Plus is the sole option if you choose the PDK. Regardless of the gearbox option, PTV is the only option when ordering the new Boxster and Cayman. The Panamera is restricted to PTV Plus and only offers PDK (at least in the United States). In the Panamera, PTV Plus is also packed with PDCC, and PDCC may only be purchased in conjunction with the air suspension. In the Cayenne with automatic transmission only, PTV Plus is available as a stand-alone option.
Using a differential to vector torque
A differential (commonly referred to as a “diff”) transfers engine torque and power to the driven wheels of the vehicle in an equitable distribution.
Normal differentials, sometimes known as “open” diffs, are unable to regulate which wheel receives the most torque. The engine’s power will follow the path of least resistance and continue to spin the slipping wheel rather than the one that still has grip if one wheel begins to spin (due to ice, water, or mud on the road).
The distribution of the power is electrically controlled by a torque vectoring system. It accomplishes this utilizing tiny clutches inside the differential, which precisely control how much torque is applied to each wheel and, thus, how much slipping is permitted. This will depend on the amount of grip the wheels have and the demands the driver makes of them.
A limited-slip differential (LSD), which does a similar task utilizing mechanically controlled devices, is not the same as this. However, an electronic system can actively redistribute this power and torque to the tire with the best grip. An LSD can restrict power to a wheel that doesn’t need it.
What does Porsche torque vectoring mean?
What Is the Process of Porsche Torque Vectoring? PTV functions by deftly braking the rear wheels when necessary to deal with the rear differential lock. This feature will moderately provide braking pressure to the inner rear wheel to enable tight cornering.
What does a vehicle’s torque vectoring do?
Torque vectoring: what is it? The capacity of a car to change the torque in each wheel is known as torque vectoring technology. A automobile can transmit torque between a specific wheel or axle dependent on cornering thanks to torque vectoring technologies. This technological idea aims to enhance vehicle dynamics while also enhancing steering response and handling.
Torque vectoring is a mechanical operation that takes place on an internal combustion engine-powered vehicle. However, with electric vehicles with numerous independent wheel-drive motors, software chooses how much each motor should operate. The development of torque vectoring systems for electric vehicles presents a problem in ensuring that each individual motor, component, and subsystem functions appropriately. The interplay between various subsystems (mechanical, electrical, and control systems) must also be understood and quantified early enough in the development cycle of an electric vehicle. In order to identify subsystem requirements based on overall electric vehicle performance targets at the initial design stage, a model must accurately reflect these many components.
Tesla torque vectoring: what is it?
A new high-performance driving mode for the Model S Plaid was introduced this week by Tesla. Similar to the Model 3 Track Mode, the Plaid Track Mode modifies the vehicle’s capabilities to prioritize driving on a racetrack.
The automaker explained its intentions for Plaid Track Mode in a blog post from January 6: “With Plaid Track Mode, our goals were simple: achieve the quickest lap time for a production electric vehicle at Germany’s Nurburgring, and allow individual adjustability of stability control, handling balance, and regenerative braking to give drivers more authority over vehicle control at the racetrack.”
The driving mode emphasizes powertrain cooling, torque vectoring, and changeable dynamics settings to enable drivers attain the best lap times possible. It was created to take advantage of the Model S Plaid’s 1,000 horsepower (1,014 PS/746 kW) of power.
To begin, the setting lowers the battery pack’s temperature as much as it can to produce a chilled thermal mass. This aids in keeping the system cool for a longer period of time, enabling drivers to use the car’s performance for more laps, coupled with the shared coolant loops between the battery and motors.
The power units have also been used by Tesla’s engineers to assist with steering. According to the manufacturer, the Model S may help spin the vehicle by sending extra power to the outside wheels thanks to torque vectoring. Additionally, it can modify the front-to-back torque distribution to enhance turn-in response. In order to recover more energy, lessen the strain on the brakes, and improve the driver’s controllability with a single pedal, the Plaid Track Mode additionally boosts regenerative braking power to its highest level. It can still be modified in the infotainment screen along with the settings for the stability control.
In contrast, Tesla’s Vehicle Dynamics Controller is designed to evaluate steering angle, accelerator position, and brake pedal inputs to determine where the driver wants to place the car and to permit tire slippage to offer them more control.
Additionally, the adaptive suspension damping is tuned for track handling with the car’s lowest ride height. Rebalanced damping reduces pitch and yaw while allowing the car to settle more quickly over uneven terrain like curbs.
Last but not least, the infotainment system’s driving mode offers a separate screen configuration that includes a thermal monitor, lap timer, G-meter, dashcam video capture, and telemetry, among other possibilities.
Tesla doesn’t name a price for the Track Mode, but given that it just modifies the car’s current capabilities, it’s possible that the cost of the vehicle will cover it. The carmaker also advises using the Plaid Track Mode in conjunction with its recently unveiled Model S Plaid Carbon Ceramic Brake Kit, which is an optional $20,000 add-on.
What does torque vectoring provide as a means of?
Torque vectoring, to put it simply, is a computerized system that regulates the amount of power your car’s engine or motors deliver to each particular wheel. A car with torque vectoring will have improved traction on slick terrain and be able to accelerate more quickly since it can better manage power.
This task is carried out in various ways by various torque vectoring systems. even though they all aim to achieve the same thing.
What about torque vectoring on the Taycan?
For variable torque distribution between the rear wheels, the optional Porsche Torque Vectoring Plus (PTV Plus) system uses an electronically controlled differential lock on the rear axle. On the one hand, stopping the inner wheel on the bend can produce more yaw torque on the rear axle. This guarantees an even more nimble steering reaction from the car. On the other hand, it deliberately locks the differential when accelerating out of corners, which increases traction.
What is a system of active torque vectoring?
With the aid of wheel sensors, Subaru’s Active Torque Vectoring system improves steering reaction and traction on the road, allowing you to turn more skillfully and avoid unforeseen dangers. Active Torque Vectoring provides brakeforce to your vehicle’s inner wheel or wheels as you navigate a corner in order to give the outer wheel the best possible drive power. As a result, you can power through curves with more assurance thanks to smoother steering control and reduced understeer.
