Pursuing our vision for net-carbon-negative commercial transportation is ambitious, real and achievable through our technology.

THE NATURAL (GAS) ADVANTAGE: A net-carbon-negative emissions solution for electrified trucks and commercial fleets, when using renewable natural gas.

Renewable natural gas is produced from biowaste, distributed through existing natural gas pipelines and purchased through established gas utility channels. It is widely available today and new sources are in development.

Ultimately, we believe that renewable natural gas offers commercial fleets with an attractive option to achieve carbon negative status.

Intelligent Electric

Performance and environmental data informs machine learning algorithms to optimize emissions performance and efficiency. All new software features and updates are delivered remotely.

lowest 7 year total
cost of ownership

Hypertruck ERX™ provides a 7-year cost of ownership unmatched by any existing and announced diesel or battery electric Class 8 trucks.


Hypertruck ERX™ supports your existing service, support and operational infrastructure. CNG stations exist on some routes. No massive solar arrays or expensive electrical grid upgrades needed.


Drivers already familiar with OEM truck operation will find the Hypertruck ERX™ Co-Pilot Driver Display supplements everything a driver knows about how the truck is performing.

*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 up to 1,300 miles, charging its batteries en-route, and can be refueled in approximately 10 minutes.

Industry Leading
Payload Capacity

Hypertruck ERX™ offers the greatest payload capacity when factoring in the increased gross vehicle weight allotments for natural gas commercial vehicles or the reduced engine weight. Fleets can haul more freight, not battery weight, enabling return on investment.

none of the Idling,
all of the Driver comfort

Hypertruck ERX™ intelligently manages power generation providing auxiliary power for in-cab electronics and HVAC systems to reduce or eliminate idling when the driver is “hoteling” in the truck.

*increased electric range can be configured to order

The Hypertruck ERX™ is a net-carbon-negative electrified powertrain option for Class 8 commercial vehicles, when using RNG.
icon_rng_rng availability


RNG is delivered through the same existing nationwide infrastructure as natural gas. RNG is widely available today and new sources are in development.

icon_rngadvantage_safe and fast refueling

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 North America.

longer range

With an estimated range of over 1,300 miles between fill ups, Hypertruck ERX™ can travel as far as diesels, and substantially greater than other proposed solutions, including competitors’ announced long-haul Class 8 commercial BEVs and FCEVs
