HexaRev is VI-grade’s most advanced 6-DoF motion platform, designed to overcome the limitations of traditional hexapods.
VI-grade announced the official launch of HexaRev, its latest and most advanced driver-in-the-loop (DiL) motion platform. The HexaRev was exclusively unveiled in May at the 2025 Zero Prototypes Summit, held at VI-grade’s SimCenter in Udine, Italy.
HexaRev represents a new benchmark in simulation-led development and is a significant technological milestone in VI-grade’s Full Spectrum Simulator (FSS) product family, redefining the boundaries of motion realism and immersive simulation. With a new mechanical architecture and direct-drive design, HexaRev delivers higher fidelity, system responsiveness, and motion efficiency, making it the most advanced 6-degree-of-freedom (6-DoF) simulator ever developed by VI-grade.
This 6-DoF platform is designed to overcome the limitations of traditional hexapod-based motion systems. While conventional designs have restricted motion envelopes during multi-axis input, HexaRev introduces a new mechanical and kinematic concept that expands usable motion during complex, combined maneuvers. This enables development teams to evaluate vehicle behavior in highly dynamic scenarios, such as braking while cornering or acceleration through a chicane, with greater realism and accuracy.
Key highlights include:
- Approximately 50% improvement in motion envelope-to-footprint efficiency over traditional hexapods
- Direct drive architecture with no belts, gears, or ball screws, resulting in low latency and virtually zero mechanical noise or parasitic vibration
- Mechanical simplicity that increases reliability and minimizes maintenance
When combined with VI-grade’s Hyperdock, the HexaRev platform transforms into an FSS, capable of delivering synchronized motion, vibration, and sound for a complete sensory experience. The full HexaRev FSS configuration offers:
- Motion: Accurate, real-time 6-DoF vehicle movement
- Vibration: 7-DoF high-frequency tactile feedback at key driver touchpoints, replicating road texture, engine behavior, and chassis harmonics
- Sound: Immersive acoustic rendering delivered through cockpit speakers or headphones
These features are fully integrated with VI-grade’s proprietary VI-ZeroLatency technology, creating an ultra-responsive simulation environment that empowers drivers and engineers to experience digital prototypes with unparalleled realism.
HexaRev joins the VI-grade Full Spectrum Simulator family alongside the Compact FSS (launched in 2023) and DiM FSS (2024), forming a comprehensive portfolio of simulation solutions tailored to a wide range of applications. From vehicle dynamics and ride comfort to NVH, ADAS, and HMI evaluation, HexaRev is engineered to deliver the highest levels of immersion and precision for virtual vehicle development. Its debut at the 2025 Zero Prototypes Summit attracted top industry leaders, engineers, and simulation specialists, all eager to experience the next leap in DiL technology.
