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.

Why We Race

Racing 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.

What We Test

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.

How We Improve

Test. Learn. Improve.

1 · TestRun the hybrid drivetrain hard in races and shakedowns.

2 · LogCapture data from every system, every mile.

3 · LearnFind what wore, what overheated and what held up.

4 · ImproveFeed fixes into the next build and the Arrowline product.

Test Platform

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.

The Goal

1,000

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.
