The school bus experts at Thomas Built have just released the first all-electric, square-bodied Type D school bus in the company’s storied history – and they’ve given their new bus a friendly, pun-tastic name. Kids, meet Wattson!
Properly called the Saf-T-Liner eHDX2 Wattson, this latest transit-style Type D bus from North Carolina-based Thomas Built combines a flat front, high seating capacity, and superior driver visibility with clean, quiet, electric power from Cummins Accelera.
“Wattson represents our next step in electrification,” said TJ Reed, president and CEO of Daimler Truck Specialty Vehicles. “(Wattson) reflects our belief that the best electric solutions are the ones that feel familiar, fit within your fleet and are built to last. That’s what we’ve heard from our customers, and that’s what we’re delivering.”
The bus offers 150 miles of estimated range thanks to a huge 246 kWh li-ion battery pack. That battery funnels electrons to the same, ultra-efficient 295 hp 14Xe eAxle with 750 lb-ft of peak tq as the recently-revealed Jouley, offering more than enough “get up and go” to get kids safely across multilane highways and up even the gnarliest rural mountain inclines. And, of course, without the freezing concerns that can stop a diesel fleet cold during extreme temperature drops.
And, because Wattson is based heavily on Thomas Built’s existing Type D body, schools’ preferred upfitting solutions should bolt right in. “We know electrification can feel like a big step,” continued Reed. “With Wattson, we’re making that step easier by giving districts a familiar Type D solution they already trust – now in electric.”
Wattson is available for order now, with first deliveries scheduled for early 2026. The bus is capable of 120 kW DC fast charging, and is V2G capable.
Electrek’s Take
It’s almost universally accepted that school buses are prime candidates for electrification. They tend to operate on short, local routes, in stop-and-go traffic, and in close proximity with some of the most vulnerable populations in the country, in terms of respiratory illness and physical safety (just imagine a kid trying to yell “STOP!” at a bus driver and being heard over the din of noisy kids and a revving diesel). The fact that electric school buses can reduce a district’s operating costs and serve the public as a portable power center in an emergency are just icing on the electric cake.

I think they could go one better and add solar panels in the roof with all that real estate going to waste. Think of it - a bus that recharges itself between morning and afternoon routes! (Of course at 246kW you're not going to fully charge on solar in my lifetime, but they could add a few miles.)
Here’s hoping all our kids’ schools have a chance to trade in their gross diesel school bus for something like Thomas Built’s Wattson sooner than later.
