The Bell HP6 RD-4C/EC Carbon Fiber Racing Helmet is a professional-level closed-cockpit helmet engineered for drivers who need maximum protection, integrated communications, and hydration capability. Developed using technology from Bell's flagship HP7 platform, the HP6 combines an ultra-lightweight advanced carbon fiber shell with FIA 8860-2018 homologation for demanding professional motorsports applications.
The RD-4C/EC configuration takes the HP6 platform further with an integrated radio communication system, electronic earcup speakers, and hydration system. This makes it particularly well suited for endurance racing, GT competition, touring cars, and other closed-cockpit environments where clear communication and driver hydration are critical.
Bell HP6 RD-4C/EC FIA 8860-2018 Helmet Overview
The Bell HP6 was developed specifically for closed-cockpit racing. Its wide eyeport provides excellent forward and peripheral visibility while the advanced carbon fiber shell keeps overall helmet weight to a minimum.
An advanced multi-density, multi-piece energy-absorbing liner provides the impact-management performance required for FIA 8860-2018 homologation. Factory-installed HANS anchors allow the helmet to be used with compatible head-and-neck restraint systems without requiring additional anchor installation.
Integrated Radio Communication and Hydration
The RD-4C/EC version of the Bell HP6 is designed for racers who need communication and hydration equipment integrated directly into the helmet. Electronic speakers are installed within earcups to provide improved audio performance while helping isolate the driver from cockpit noise.
The helmet also incorporates a hydration system and dedicated internal routing for communication and drinking components. Integrating these systems into the helmet helps reduce loose wiring and tubing around the driver's head and cockpit.

FIA 8860-2018 Advanced Carbon Fiber Construction
The HP6 RD-4C/EC uses Bell's Advanced full carbon fiber shell technology to provide exceptional strength while minimizing helmet weight. FIA 8860-2018 is designed for the highest levels of motorsports competition and requires significantly more demanding impact and performance testing than many conventional motorsports helmet standards.
The carbon shell is paired with an advanced multi-density, multi-piece liner engineered to manage impact energy while maintaining the compact fit and comfort expected from Bell's High Performance Series.
Wide Eyeport for Closed-Cockpit Racing
A wide eyeport is one of the defining features of the Bell HP6. The larger opening improves the driver's field of view, making it especially useful in GT cars, touring cars, prototypes, endurance cars, and other enclosed race vehicles where visibility can already be limited by cockpit structure and seating position.
The helmet uses Bell's SE06 3mm DSAF shield system for excellent optical clarity and anti-fog performance.
Ventilation and Forced-Air Compatibility
Multiple extraction vents help move warm air out of the helmet and improve driver comfort during extended track sessions. The HP6 can also be configured with an optional top forced-air intake mounted to either the left or right upper ventilation location.
- Integrated extraction vents improve airflow
- Optional top forced-air intake can be mounted on either side
- Compatible with external helmet cooling systems
- Quick Lock V10 forced-air components are available
- Compatible with Maglock forced-air connections
