Concept render
Validated in the desert.
We race to test. Desert racing is where DXR's hybrid drivetrain and DXR Arrowline range extender prove themselves under real-world conditions.
2027 Test Program Sponsor or FollowRacing is our test lab
A desert race packs months of hard use into a few days: hundreds of miles of rock, silt and whoops, extreme heat and nowhere to plug in. That makes every race real-world validation and accelerated durability testing for our hybrid drive.
What breaks gets fixed. What works gets proven. Every lesson goes straight back into the DXR Arrowline range extender and the products we build on it.
Built to be pushed
Heat
Long, hot, slow sections that stress the generator, battery and electronics.
Dust
Hundreds of miles of fine silt to prove filtration, sealing and cooling.
Vibration
Constant whoops and big hits that test mounts, wiring and connectors.
Sustained load
Hour after hour of continuous demand on the drivetrain, not a quick sprint.
Thermal management
Keeping the engine, generator and battery in their operating range in desert heat.
Data logging
Temperatures, power and fuel use logged on every test run as instrumentation comes online, so results are measured, not guessed.
Test. Learn. Improve.
MOAB #1351
MOAB is our rolling test bench: a Jeep JL-based series-hybrid race truck. The engine never drives the wheels. An onboard diesel engine turns a generator, the generator keeps the battery charged, and electric motors drive the wheels.
Fuel is carried on board, so it can keep going on remote desert courses where battery-only vehicles have to stop.
Currie axles
Heavy-duty axles front and rear.
Fox shocks
Race-valved suspension for whoops and big hits.
Protected steering
Steering ram tucked behind the tie rod.
Desert cooling
Cooling and filtration sized for long, dusty miles.
off-road miles. No stops.
Our goal is to run 1,000 off-road miles without stopping. It's a target we're building toward, and every test and race gets us closer.

Testing progress
Concept & layout
Series-hybrid architecture chosen and packaged into the JL test platform.
Axles & suspension
Currie axles and Fox suspension laid out in CAD, then checked through full travel.
Steering redesign
Steering ram moved behind the tie rod for protection. Mock-up fitment is next.
Instrumentation
Data logging planned for temperatures, power and fuel use.
Up next
