Wing II · Industrial Mobility

Series-hybrid flex-fuel glider trucks, built by the block that drives them.

No mechanical driveline. A Brogen e-axle does all the work, a LiFePO4 buffer absorbs the duty cycle, and a small flex-fuel genset holds state of charge on long hauls.

Build sequence

01

Glider intake

Cab-and-frame gliders arrive without powertrain. We survey the rails, strip the harness, and log every component into the shared ledger.

02

E-axle fitment

The Brogen e-axle drops into a purpose-built subframe. High-voltage routing is done by certified apprentices under a licensed supervisor.

03

Buffer & genset

LiFePO4 modules are stacked into a crash-braced tunnel pack. The flex-fuel genset runs only as a charger, at a single efficient load point.

04

Commission & hand-off

Dyno verification, thermal soak, and a two-day operator course. The truck leaves with its own service manual and parts list.

Why series, why flex-fuel

A series layout lets the engine ignore the road entirely. It runs at one load point or not at all, which is where a small combustion unit is actually efficient.

Flex-fuel means the truck accepts what the district can produce — ethanol from regional stock, biogas from the digesters, petrol only as a fallback.

LiFePO4 carries the duty cycle without cobalt, tolerates deep cycling, and retires into the campus UPS bank when it drops below traction spec.
