Sim-Lab Announces DDX TorqueSync Wheelbases – 350V Architecture and 100kHz Control
Sim-Lab has officially announced the DDX TorqueSync wheelbases, marking one of the most technically ambitious launches in the sim racing hardware space to date. Featuring a 350V electrical architecture and a 100kHz control loop, the DDX TorqueSync platform signals a major leap forward in direct drive force feedback technology.
But what do these numbers actually mean for sim racers—and why is this announcement such a big deal?
In this deep-dive, we’ll explain the technology behind DDX TorqueSync, how it compares to existing direct drive systems, and what it could mean for the future of high-end sim racing.
What Is Sim-Lab DDX TorqueSync?
The Sim-Lab DDX TorqueSync is a next-generation direct drive wheelbase platform designed around ultra-high-voltage motor control and extremely fast torque feedback processing.
At its core, TorqueSync is built to deliver:
- Faster torque response
- Higher signal resolution
- Reduced latency
- Greater force feedback fidelity
This places DDX TorqueSync squarely in the ultra-high-end direct drive category, competing not just on torque numbers—but on control precision and realism.

Why 350V Architecture Matters
Most current direct drive wheelbases operate at much lower voltages, typically optimized for safety, cost, and efficiency. Sim-Lab’s move to a 350V architecture is a bold engineering choice.
Key Advantages of High-Voltage Architecture
- Faster torque rise time
Higher voltage allows the motor to reach target torque more quickly. - Improved torque linearity
Torque delivery remains consistent across the entire range. - Lower current for the same torque
Reduced electrical losses and cleaner signal delivery. - More precise force modulation
Especially noticeable in micro-details like road texture and tire slip.
In practical terms, this means sharper, cleaner, and more immediate force feedback—particularly during rapid transitions.
Understanding the 100kHz Control Loop
The second headline feature of DDX TorqueSync is its 100kHz control frequency.
What Is Control Loop Frequency?
Control loop frequency determines how often the wheelbase:
- Reads steering inputs
- Processes force feedback data
- Updates motor torque output
A 100kHz control loop means the system updates 100,000 times per second.
Why This Is Significant
- Dramatically lower latency
- Higher fidelity force feedback signals
- More accurate reproduction of subtle forces
- Improved stability during high-frequency effects
Compared to traditional systems, this enables force feedback that feels smoother, more natural, and more connected to the car.

TorqueSync: More Than Just Raw Power
Sim-Lab’s announcement emphasizes that TorqueSync is not about chasing maximum Nm numbers.
Instead, the focus is on:
- Torque accuracy
- Timing precision
- Signal clarity
- Feedback realism
This aligns with a growing trend in sim racing hardware: quality of torque over quantity of torque.
Many experienced sim racers already agree that better signal processing matters more than brute force.
How DDX TorqueSync Compares to Existing Direct Drive Wheelbases
| Feature | Typical DD Wheelbase | Sim-Lab DDX TorqueSync |
|---|---|---|
| Voltage Architecture | Low–Mid Voltage | 350V High Voltage |
| Control Frequency | Low–Mid kHz | 100kHz |
| Torque Focus | Peak Nm | Torque precision & timing |
| Signal Resolution | High | Ultra-high |
| Latency | Low | Extremely Low |
While many current high-end wheelbases already feel excellent, DDX TorqueSync aims to push the ceiling higher.

Who Is DDX TorqueSync Designed For?
This wheelbase platform is clearly aimed at:
- Competitive sim racers
- Esports professionals
- Hardware enthusiasts
- Drivers seeking maximum realism
- Users with rigid cockpits and premium setups
This is not an entry-level product—it’s designed for sim racers who already understand what high-end direct drive can offer and want more.
Hardware Requirements and Considerations
With advanced architecture comes responsibility.
To fully benefit from DDX TorqueSync, users will likely need:
- A rigid aluminum cockpit
- Proper grounding and power setup
- High-quality steering wheels and quick releases
- Software capable of delivering high-resolution FFB data

What This Means for the Sim Racing Industry
The announcement of DDX TorqueSync has broader implications:
1️⃣ Raising the Technical Bar
Other manufacturers may now be pressured to improve:
- Control loop speeds
- Power delivery architecture
- Signal processing pipelines
2️⃣ Shift Toward Signal Fidelity
The industry continues moving away from marketing torque numbers toward engineering-driven realism.
3️⃣ Closer to Real Motorsport Simulators
High-voltage architectures and ultra-fast control loops are common in professional driver training simulators—not consumer hardware.
Sim-Lab is effectively bringing pro-grade technology into the consumer space.
Potential Challenges of High-Voltage Systems
While exciting, this approach isn’t without challenges:
- Higher engineering complexity
- Stricter safety requirements
- Potential cost increases
- More demanding manufacturing standards
However, Sim-Lab’s reputation for engineering quality and precision manufacturing suggests they are well-positioned to manage these challenges.
Is DDX TorqueSync the Future of Direct Drive?
It’s too early to declare a winner—but one thing is clear:
Sim-Lab DDX TorqueSync represents a major technological milestone.
Just as direct drive replaced belt-driven wheels, advanced high-voltage, high-frequency control systems may define the next era of sim racing.
Final Verdict: A Bold and Exciting Leap Forward
With the announcement of the DDX TorqueSync wheelbases, Sim-Lab has made a clear statement:
The future of sim racing isn’t louder force feedback—it’s smarter, faster, and more precise feedback.
The combination of 350V architecture and 100kHz control positions DDX TorqueSync as one of the most technically advanced direct drive platforms ever announced.
For serious sim racers and hardware enthusiasts, this is a development worth watching very closely.
My name is Michael “Mick” Carter, and I’m a dedicated sim racing enthusiast with a deep love for motorsport. I first discovered sim racing in 2015 when a friend introduced me to a Logitech G27 and Assetto Corsa—an experience that immediately hooked me. Since then, I’ve gone from basic gear to advanced direct drive setups, VR headsets, and custom racing rigs, constantly refining my driving technique and equipment.
I mainly race in iRacing, ACC, and rFactor 2, focusing on GT3 endurance and open-wheel events. I’m not a professional driver—I’m simply someone who enjoys the craft of racing: learning car behavior, improving lap times, and battling for position with respect and skill.
I share what I’ve learned so others can build setups they enjoy and grow their own passion for sim racing. For me, the joy is in improving, one race at a time.
