- Revoy EV raised $27 million in Series A funding led by Standard Capital, with Doerr Capital, Time Ventures, Y Combinator, and Leap Ventures participating.
- The capital will fund a cheaper, lighter "second-generation" hybrid trailer dolly with a smaller battery but similar fuel economy gains.
- Revoy just completed a year-long pilot with Ryder System and plans to deploy four more units on a 200-mile Pacific Northwest route by end of 2025, with "dozens" more in operation by end of 2027.
- The dolly slots between a semi truck and trailer, using an electric drive axle to cut diesel use roughly in half on a 250-mile run — a range comparable to the Volvo VNR Electric and Freightliner eCascadia.
- Revoy sells the dolly as a pay-by-the-mile service with no upfront cost, supported by two battery swap stations in Texas and Arkansas, with California and Oregon stations planned.
- Founder Ian Rust estimates two-thirds of loads can accommodate the dolly's 22,000-pound weight, which otherwise consumes 22,000 lbs of the 80,000 lb GCWR payload limit and doesn't qualify for the 2,000 lb ZEV allowance.
Why it matters: For the two-thirds of loads that can spare the weight, Revoy's pay-by-the-mile model removes the capex barrier to partial fleet electrification — but the 22,000 lb dolly eats a full 22,000 lbs of legal payload and disqualifies the remaining one-third of cargo outright, which is why the Series A is pointed at a lighter second-gen design before scaling deployment.
