Based on a Peterbilt 579 commercial semi truck, the ReVolt EREV hybrid electric semi truck promises 40% better fuel economy and more than twice the torque of a conventional, diesel-powered semi. The concept has promise – and now, it has customers.
Austin, Texas-based ReVolt Motors scored its first win with specialist carrier Page Trucking, who’s rolling the dice on five of the Peterbilt 579-based hybrid big rigs — with another order for 15 more of the modified Petes waiting in the wings if the initial five work out.
The deal will see ReVolt’s “dual-power system” put to the test in real-world conditions, pairing its e-axles’ battery-electric torque with up to 1,200 miles of diesel-extended range.

The ReVolt team starts off with a Peterbilt, then removes the transmission and drive axle, replacing them with a large genhead and batteries. As the big Pete’s diesel engine runs (that’s right, kids – the engine stays in place), it creates electrical energy that’s stored in the trucks’ batteries. Those electrons then flow to the truck’s 670 hp e-axles, putting down a massive, 3500 lb-ft of Earth-moving torque to the ground at 0 rpm.
The result is an electrically-driven semi truck that works like a big BMW i3 or other EREV, and packs enough battery capacity to operate as a ZEV (sorry, ZET) in ports and urban clean zones. And, more importantly, allows over-the-road drivers to hotel for up to 34 hours without idling the engine or requiring a grid connection.
That ability to “hotel” in the cab is incredibly important, especially as the national shortage of semi truck parking continues to worsen and the number of goods shipped across America’s roads continues to increase.
And, because the ReVolt trucks can hotel without the noise and emissions of diesel or the loss of range of pure electric, they can immediately “plug in” to existing long-haul routes without the need to wait for a commercial truck charging infrastructure to materialize.
“Drivers should not have to choose between losing their longtime routes because of changing regulatory environments or losing the truck in which they have already made significant investments,” explains Gus Gardner, ReVolt founder and CEO. “American truckers want their trucks to reflect their identity, and our retrofit technology allows them to continue driving the trucks they love while still making a living.”
If all of that sounds familiar, it’s probably because you’ve heard of Hyliion.
Hyliion electric semi truck

Before it changed its focus to develop Carnot-cycle generators and gensets, Austin-based Hyliion built a number of EREV Peterbilts using the then-new 15L Cummins diesel as a generator and employing the same sort of battery and e-axle-arrangement as ReVolt.
In addition to being located in the same town and employing the same idea in the same Peterbilt 579 tractor, ReVolt even employs some of the same key players as Hyliion: both the company’s CTO, Chandra Patil, and its Director of Engineering, Blake Witchie, previously worked at Hyliion’s truck works.
Still, Hyliion made their choice when they shut down their truck business. ReVolt seems to have picked up the ball – and their first customer is eager to run with it.
“Our industry is undergoing a major transition, and fleet owners need practical solutions that make financial sense while reducing our environmental impact,” said Dan Titus, CEO of Page Trucking. “ReVolt’s hybrid drivetrain lowers our fuel costs, providing our drivers with a powerful and efficient truck, all without the need for expensive charging infrastructure or worrying about state compliance mandates. The reduced emissions also enable our customers to reduce their Scope 2 emissions.”
Page Trucking has a fleet of approximately 500 trucks in service, serving the agriculture, hazardous materials, and bulk commodities industries throughout Texas. And, if ReVolt’s EREV semis live up to their promise, expect them to operate a lot more than 20 of ’em.
