*model shown is subject to change

Typical full EV solutions require a complex infrastructure and demand a lot from the grid.
The Hyliion ERX™ powertrain is a fully electric drivetrain Class 8 truck that recharges itself by efficient en route charging.


Zero to sixty in 20 seconds, fully loaded at 80,000 lbs. Machine learning continuously optimizes power output.


Using up to 100% RNG, Hypertruck ERX™ electric power generation is up to 35% less expensive than diesel on a miles per diesel equivalent gallon of fuel.

Fast Refuel & Long Distance

When fully loaded at 80,000 pounds, Hypertruck ERX™ can travel over 1,300 miles, charging its batteries en-route, and can be refueled in 10 minutes or less.

Lighter than all
other Class 8 Trucks

Hypertruck ERX™ is lighter than any diesel or fully electric Class 8. Fleets can haul more freight, not battery weight, giving an even better return on investment.

Net-Negative Carbon Emissions

Fueled with renewable natural gas, Hypertruck ERX™ can deliver net-negative carbon emissions. A fleet of 389 Hypertruck ERX™ trucks offsets 100% of the GHG emissions produced in the entire state of California for a full day.

operates fully
electric when needed

Hypertruck ERX™ can travel seamlessly in and out of cities that require zero emissions vehicles by operating on all electric power for up to 25 miles* without any performance degradation.

none of the Idling,
all of the Driver comfort

Hypertruck ERX™ intelligently manages power generation providing up to 85 hours of continuous auxiliary power for in-cab electronics and HVAC systems without the expense or emissions of idling. A virtually silent APU keeps your drivers comfortable, reduces fatigue and increases safety.

*increased electric range can be configured to order

The average diesel semi-truck emits 210 metric tons of carbon annually.
The Hypertruck ERX™ is the only Class 8 net-negative carbon producing electric powertrain.


RNG is delivered through the same existing nationwide infrastructure as natural gas. RNG will approximate 40% of transportation-consumed natural gas by year-end 2020.

safe and fast refueling

RNG Class 8 refueling is safe, fast, proven, practical and takes no more time to refuel than a Class 8 diesel. RNG is currently available in 700+ commercial vehicle filling stations across the US and Canada.

longer range

With an estimated range of over 1,300 miles between fill ups, Hypertruck ERX™ can travel as far as diesels, and more than twice the distance of comparable battery-only vehicles.

Explore the ERX on your preferred chassis



Experience the future of trucking with the Hyliion Hypertruck ERX, designed for both over-the-road long-haul and inner city freight transport.

By utilizing a renewable natural gas (RNG) fueled on-board electric generator, the ERX™ powertrain operates as a self-charging, fully electric system without the limitations of alternative battery-only solutions relying solely on grid power.

The ERX™ is incredibly powerful and produces net-negative carbon emissions.
