What makes this program significant.
First Hybrid T3U Entry
Purpose-built for a class where no hybrid had previously competed, requiring a battery system with no established precedent.
Dakar Demands
5,000+ km across sand, rock, and extreme temperature swings. The battery must survive sustained vibration, thermal cycling, and full-speed desert impacts.
Compact High-Voltage Architecture
773V peak in a package smaller than the original spec envelope, liquid-cooled and FIA-compliant.
Performance Specifications
Hover over any specification to explore its performance envelope.
Usable energy optimized for hybrid rally stage demands
Peak bus voltage under full charge
Sustained output for high-speed desert racing
Regenerative and external charge capability
System mass including enclosure and cooling circuit
Gravimetric density optimized for motorsport weight targets

Liquid Cooling
- Rim-bonded module architecture
- Validated cooling circuit
- FIA-compliant construction throughout
Built for the first hybrid T3U Dakar entry, this MonoLith™ system had to survive conditions that destroy conventional hardware: extreme desert heat, sustained vibration, and the physical punishment of high-speed off-road racing. It delivered on every requirement, in a smaller package than specified.
Why It Matters
First Hybrid T3U Battery
No prior template, no reference system. Built from the ground up for a class with no hybrid precedent.
Smaller Than Spec, More Than Required
Delivered a 1046×609×170mm pack against a 1250×700×160mm envelope while exceeding all electrical targets.
FIA-Compliant Ruggedization
Motorsport safety standards applied to a prototype build, not just performance specs.
