We build hybrid electric powertrains that work with the heavy machinery of today. Every 4QT system is drive-by-wire from the ground up — the instant-torque, software-controlled backbone that autonomous machines demand. Future-proof your fleet without sending it to the scrap heap.
From fully electric to diesel-hybrid range extension — every line shares the same control stack, so the machine you electrify today is the machine you automate tomorrow.
Proudly powering the world's first fully electric 8T dumper. Pure electric drive means full software authority over every newton-metre — autonomy ready out of the box.
| Vehicle class (unladen) | 2–4 T |
| Drive motor power (peak) | 80 kW |
| Capacity | 30 kWh |
| Recharge 0–100% | <10 min |
Taking your worksite to the next level: our proprietary iREX MK I diesel-hybrid system keeps the power flowing wherever the mission goes — no grid, no downtime, no compromise on control.
| Vehicle class (unladen) | 2–4 T |
| Drive motor power (peak) | 80 kW |
| Capacity (incl. range extender) | 110 kWh |
| Recharge / refuel 0–100% | <8 min |
Further expanding the segments we serve — and the missions we power. The MK II is the drivetrain behind the CERBERUS UGV: proven where power and autonomy are not optional.
| Vehicle class (unladen) | 3–6 T |
| Drive motor power (peak) | 120 kW |
| Capacity (incl. range extender) | 145 kWh |
| Recharge / refuel 0–100% | <5 min |
The next class up: diesel-electric power for the heaviest applications, engineered on the same autonomy-ready control architecture as the entire iREX family.
| Vehicle class (unladen) | 4–8 T |
| Drive motor power (peak) | 150 kW |
| Recharge / refuel 0–100% | <5 min |
Four subsystems, one integrated stack. Everything a machine needs to drive itself — and the power to do it all day.
Tuneable software and control algorithms, trained on years of combined field and synthetic data. This is the layer autonomy stacks plug into: full drive-by-wire authority over torque, steering and braking.
2× more power-dense LFP or NMC chemistry with continuous AC charge & discharge. Sized to the mission — including a silent, engine-off reserve when the job demands it.
Stackable for all machine types and up to 50% more efficient than alternatives — more usable power from every litre of fuel and every kilowatt-hour, with instant torque on command.
Underpinned by smart software that optimises performance and balances range extender and EV power in real time. Full telemetry and remote diagnostics — machine health without a mechanic on site.
Become the latest company to supercharge the e-line of their heavy-duty segment.
4QT powertrains are the hybrid-electric backbone of the CERBERUS unmanned ground vehicle — silent running, unlimited range, autonomy proven in field trials.
We collaborate with OEMs, construction contractors and governments to build, sell, and scale advanced powertrains for heavy equipment — the power and control layer that takes a fleet from driven, to drive-by-wire, to driverless.
Looking for a complete vehicle that fulfils your off-highway requirements — or a powertrain that makes your product line autonomy ready? Let's talk.
