Sim-Lab’s new DDX wheelbases features analysis

Sim-Lab has presented their first Direct Drive wheelbases at the SimRacing Expo this last weekend. There are two models, and the numbers are crazy. Let’s analyze what are the possible advantages of these new products.

The new Sim-Lab DDX Direct Drive Wheelbase could represent a major leap forward in the world of sim racing hardware. Designed and manufactured in Italy in collaboration with SOLO Motorcontrollers Srl, the DDX combines precision engineering, industrial performance, and open ecosystem compatibility to challenge the dominance of brands like Simucube and Asetek.

Built for Professionals: Two Powerful Versions

The DDX lineup consists of two models: the DDX26 with 26 Nm of torque and the range-topping DDX39 with 39 Nm. Launching in March 2026 at prices of €1,399 (preorder price) and €1,999 respectively, both models feature an innovative 350V internal architecture—a huge jump from the 48V standard found in most competitors. This allows instant torque response and improved dynamic range for high-speed accuracy under load.

TorqueSync™: 100kHz Force Feedback Precision

At the heart of the DDX platform lies the patented TorqueSync™ control system, operating at a staggering 100kHz torque loop frequency—more than fifty times faster than standard high-end wheelbases. This extreme responsiveness ensures lifelike force feedback detail, letting drivers feel microscopic grip changes, curb vibrations, and chassis flex with unprecedented realism.

Engineering and Technical Specifications

• 24-bit high-resolution encoder with 16.7 million counts per revolution for ultra-precise position tracking.
• Internal 1,500W PSU (1,200W PSU on DDX26) for optimal power delivery and temperature control, eliminating bulky external adapters.
• Open ecosystem architecture with USB 3.0 passthrough, one 5V power pin, and four auxiliary pins for full accessory compatibility.
• ISO-certified Italian manufacturing with TÜV SÜD safety certification and a 4-year global warranty.
• Quick-release V2 system featuring a conical motorsport-grade interface for zero-play and repeatable wheel coupling.

Heat Management and Durability

The DDX TorqueSync™ underwent thousands of simulated driving hours at continuous maximum torque. Its active cooling system ensures thermal stability and zero performance fade. Both the motor and electronics were validated for long-term consistency, ensuring reliable operation even under extreme sim racing conditions.

Mounting and Rig Compatibility

Designed to fit seamlessly into any rig, the DDX includes precision mounting rails on all sides for both front-mount and side-mount configurations. It integrates perfectly with Sim-Lab’s P1X Ultimate and P1X Pro cockpits, while also supporting custom setups. Additional top slots allow users to attach DDUs or lightweight monitor mounts for a fully optimized racing environment.

Performance Analysis

The leap to 350V architecture gives the DDX unparalleled responsiveness compared to conventional 48V systems. Combined with the 100kHz control frequency, racers experience smoother, faster torque transitions that feel incredibly natural when countersteering or taking complex corners. The result is purely linear feedback, zero cogging, and instant force delivery.

Direct Comparison: How It Stacks Up

Brand	Model	Torque	Voltage	Ecosystem	Price (€)
Sim-Lab	DDX26	26 Nm	350 V	Open	1399
Sim-Lab	DDX39	39 Nm	350 V	Open	1999
Simucube	3 Pro	25 Nm	48 V	Semi-Closed	1500
Asetek	Invicta	27 Nm	48 V	Semi-Closed	1449
Fanatec	Podium DD2 QR2	25 Nm	48 V	Semi-Closed	1499

The Sim-Lab DDX could set a new benchmark in performance for direct drive systems. With its high-voltage platform, industrial-grade components, and ultra-fast feedback control, it could deliver a driving experience that feels exceptionally real. Whether you’re an eSports competitor or a dedicated enthusiast, the DDX could offer uncompromising power, precision, and flexibility.
