Porsche’s explanation of technology behind Power Steering Plus
Total 911 looks more closely at an optional aid device that makes navigating tight spaces in your Neunelfer easier.
Our “technology explained” feature in this issue focuses on Porsche Power Steering Plus, a software-based system rather than a mechanical one on the Porsche 911. The “PSP” is a speed-sensitive power assistance steering system that was first offered as an option for the 991 (and is still accessible as an option on the 992 generation).
The 911’s steering ratio is automatically adjusted below 31 mph to facilitate maneuvering and parking; Porsche claims that at higher speeds, the system hardens up and reacts more precisely. You won’t actually notice much of a difference between this and a 991 or 992 without PSP while you’re moving quickly, which in our opinion is absolutely positive. PSP, on the other hand, excels at very low-speed, tight moves, such as parallel parking, and enables you to turn the steering wheel from lock to lock without feeling like you’re working out. With their longer wheelbases and added heft, the 991 and 992 generations, where cars like the 1,565kg Turbo S can be found, are very helpful in these situations.
We at Total 911 understand the Neunelfer has to be agile and practical enough for a variety of lifestyles, particularly for those who mostly reside in cities and other built-up areas. It is a rather polarizing system among enthusiasts and one that purists tend to balk at. Should your 911 not already have PSP optioned from the factory, the system can be retrofitted because PSP is a software upgrade rather than a mechanical one.
The speed of the vehicle serves as the basis for Power Steering Plus operation. At high speeds, it reacts swiftly and precisely, and at lower speeds, it offers more robust steering assistance.

Uses electric power steering in Porsche?
The Porsche 911’s power steering has typically been hydraulically assisted since it was first used on the 964 in 1989. Thanks to pistons inside the steering rack, this system forces fluid to assist with turning the steering. A pump powered by an engine applies pressure to the fluid.
When it came to the Porsche 991 model, Porsche switched to a fully electric assistance system created in collaboration with ZF. With the new technology, a second pinion gear and an electric motor positioned on top of the rack work together to help move the steering when the steering wheel is turned.
The 991’s EPAS is far more straightforward than the hydraulic system because it does not require an engine-driven pump or the rear-to-front plumbing necessary to force the pressurized fluid to the steering rack.
Additionally, the electric motor uses no engine power, increasing efficiency, and the entire system is lighter than the power steering in the 997.
Porsche’s EPAS, however, uses the wealth of data gathered by the numerous steering and wheel sensors to offer the appropriate assistance rather than calculating it from the driver’s input.
The end result is a rack that can continuously adjust the amount of help offered and, when sports modes are engaged, can increase steering weight by modifying the system’s software.
Many high-level feedback frequencies, particularly those near the dead-ahead steering position, are likewise filtered out by the new EPAS. As a result, driving is more comfortable because it is simpler to maintain a straight line without having to compensate for every little bump and curve on the road.

It has a speed-sensitive power steering system as part of its Standard Power Steering Plus feature. The steering tightens up and reacts more precisely as you increase your speed. The steering ratio adjusts for easier parking and maneuvering when the Porsche Macan GTS is moving at a slower speed.
What exactly is the Porsche Premium Package Plus?
The Premium Plus Package ($5,050) adds a panoramic roof system, 14-way power adjustable front seats, and ventilated front seats to the contents of the Premium Package. The final cost is $56,250 when the base price is combined with the $1,350 destination fee.
The electric power steering is managed by what?
Based on the torque being given to the steering wheel by the driver, the steering wheel position, and the vehicle’s speed, the EPS electronic control unit (ECU) determines the amount of aiding power required. With an applied force, the EPS motor rotates a steering gear, lowering the driver’s necessary torque.
What is the mechanism of the electric power steering?
An electric motor powered by the car’s electrical system is used by the electric power steering to help with steering. A computer determines the amount of assistance that has to be added after sensors measure the torque or effort the driver is exerting at the steering wheel. The ability of electric power steering to adjust to certain driving circumstances is its main advantage over hydraulic power steering.
With a car examination from an auto repair shop, problems like a power steering leak can be avoided. It’s one of the greatest methods to guarantee that the remainder of your vehicle’s essential parts, like the power steering system, can operate at their peak efficiency. If turning seems more difficult than usual, your power steering may be malfunctioning. Your steering should be responsive and easy to use. Make an appointment or drive your car to a nearby auto repair shop for power steering maintenance.
What is the Porsche entry-drive system?
Porsche Entry and Drive allows you to access the luggage regions in addition to unlocking the driver’s door. Simply put your hands in close proximity to the Porsche Crest on the lid of the front luggage box or the logos on the back. Once more, after verification of your encrypted key code, the luggage compartment’s lid will unlock.
Does fluid get used in electric power steering cars?
Electric power steering has increasingly been the standard for cars since the early 2000s. This is mainly due to the fact that EPS systems are typically more straightforward and maintenance-friendly than their hydraulic counterparts. Electric systems are more fuel-efficient than hydraulic ones since they do not require power steering fluid to function and just draw power when necessary.
Additionally, EPS makes it possible for contemporary driver-assist systems on which we have come to rely, such automatic parking and lane-keep assistance. As we approach the era of autonomous vehicles, it will also become increasingly important.
When compared to hydraulic power steering, EPS is better at correcting for wheel misalignment and adverse road conditions including high winds and uneven terrain. Additionally, because the system is entirely electronic, it is simpler to modify the software to improve the accuracy of the power assistance.
Porsche Dynamic Light System: What is it?
The Porsche Dynamic Light System, or PDLS, is a function that enhances the light from your headlights on bending and turning roads and is available on vehicles like the 718 Cayman and Panamera.
Which is more effective, electric or power steering?
Hydraulic pumps and pistons are not included in vehicles using EPS systems. They do, however, have a more straightforward electric motor that works in addition to the steering signals given by the driver. By using this technique, the vehicle’s weight is decreased. Additionally, unlike hydraulic systems, the EPS system doesn’t draw power from the engine. The electric power steering system is generally more effective.
What benefits does electric power assisted steering offer?
A future-defining technology is electric power steering. It does away with the requirement for a power steering pump, hoses, hydraulic fluids, and an engine drive belt and pulley. Electric power steering offers benefits including streamlined tuning, flexible packaging, and engine-off steering assistance while also being energy-efficient and environmentally friendly. Electric power steering will be the innovation that puts hydraulics’ well-established, fifty-year-old notions to the test thanks to its improved performance.
What Porsche model is the entry-level?
Porsche’s entry-level sports vehicle is the 718 Cayman. The coupe has two doors, two seats, and a rear mid-engine. The 718 Cayman is regarded as one of the market’s pinnacle drivers’ vehicles thanks to its excellent balance and handling. Porsche introduced the current fourth generation in 2016, switching from flat-six to flat-four engines in a contentious move (though Porsche re-added some flat-six versions). Most 718 versions can be equipped with either a seven-speed PDK or a six-speed manual transmission.
The standard 718 Cayman has a four-cylinder engine that produces roughly 300 horsepower. You can advance to the new Cayman GT4 RS, which costs more than $140,000 and has amenities like the flat-six engine from the 911 GT3 among others.
How long is the lifespan of electronic power steering?
Hydraulic power steering is used in the majority of vehicles on the road now (and in the past). Power steering fluid is delivered to the power steering rack by a pump through a network of lines, improving your ability to operate the steering wheel. It is intended to make steering simpler because anyone who has ever operated a vehicle without power steering is aware of how challenging it can be.
The production of certain more recent automobiles now includes an electronic power steering system, or EPS. Compared to their older cousins, these are considerably different. The power steering pump is absent. No power steering fluid is required. An electronic power steering control unit manages the entire system. To help with greater control while driving, this gadget integrates with the other computers in the automobile.
An electric motor is connected directly to the control unit, which is placed on the dash behind the steering wheel. The steering rack is connected to this motor via the steering column.
Every time your automobile is started and moving, the power steering control unit is in action. The system continues to keep an eye on the numerous sensors it employs even if you are not actively rotating the wheel. However, since most of the components are electronic, physical wear and tear is not actually a major issue.
Your car’s power steering control unit has no defined lifespan. It should typically last the entire life of the car. However, unexpected failures can happen with electronics. Knowing the warning indications and symptoms of an impending failure of your power steering control unit or another EPS component is beneficial. These consist of:
- On the dash, the EPS Light
- power steering aid disappears (more force required to turn the wheel)
To prevent damage from overheating, your electronic power steering system may occasionally switch off automatically. Driving on steep hills with plenty of turns tends to cause this (a winding mountain road, for instance). When this happens, the system is working normally, and after the temperature drops, it won’t break down.
A qualified mechanic can help evaluate the system and perform any necessary repairs to the power steering control unit if you have concerns that your power steering control unit is failing, notice the EPS Light on in the dash, or are having any other issues with your power steering system.
Is it pricey to repair electric power steering?
Best in Automotive Repair The price range for replacing a power steering control module is $874 to $905. Between $116 to $146 is the projected cost of labor, while the cost of parts is $759. This range does not account for taxes and fees, your particular car, or your particular location.
What drawbacks exist with electric power steering?
The lack of steering feel is the biggest drawback of using an electronic system, and this is mostly a problem for purist drivers.
Less road feedback is conveyed to the driver through the steering wheel when the mechanical link to the steering rack is muffled, yet some manufacturers have nevertheless developed technologies that impart artificial feedback.
When the system has been improperly calibrated, electric power steering can also be less predictable than hydraulic power steering, which can make some electric installations feel less linear than hydraulic systems.
