Engineering & Innovation
The technical platform behind every UPT configuration.
UPT is not a one-purpose mini EV. It is a modular electric mobility platform engineered around four independently controlled in-wheel motors, modular high-capacity batteries, a configurable chassis, intelligent vehicle control, and mechanical interfaces designed for mass customization.
Engineering philosophy
Built for mass customization. Engineered for safety, longevity, and serviceability.
Most small electric vehicles are built around a fixed use case. UPT takes a different route: one shared engineering platform can become a micro utility vehicle, resort transporter, patrol unit, cargo mover, jobsite tool carrier, accessibility solution, or partner-developed specialty vehicle.
The platform approach reduces the cost and complexity of niche mobility. Instead of engineering a new low-volume vehicle for every vertical, UPT shares the expensive parts — chassis, powertrain, VCU, battery system, suspension, braking, and control logic — while allowing the upper body and task modules to change.
Platform architecture
One engineered base. Many specialized small-footprint vehicles.
The core UPT architecture separates the durable technical platform from the body and accessories — so the same parts work whether you are spec'ing a cargo mover, a patrol unit, or an accessibility vehicle.
Shared chassis and control architecture
A common frame, drive, battery, VCU, braking, and suspension logic runs across many use cases. The durable technical platform is deliberately separated from the mission-specific body and accessories, giving partners a faster pathway to specialized compact EVs without starting from a blank sheet.
Configurable body and attachment layer
Seats, cargo modules, canopies, racks, tools, sensors, and industry-specific bodies mount on the same platform logic. The upper body and task modules change; the engineered base stays the same.
Serviceable and upgradeable by design
Replaceable modules, accessible components, onboard diagnostics, and standardized mechanical interfaces support a long product life and field maintenance across demanding environments.
Proprietary engineering
The engineering stack that makes modularity practical.
UPT modularity is not one feature or a bolt-on accessory system. It comes from a complete mechanical, electrical, software, battery, control, chassis, and validation architecture designed so one compact EV platform can become many specialized light-duty vehicles.
Modular platform architecture
One shared small-footprint EV platform supports cargo, passenger, patrol, shuttle, utility, accessibility, delivery, robotic, and partner-developed specialty configurations without redesigning the full vehicle.
Distributed electric drive
Independently controlled in-wheel motors open packaging space and enable selectable FWD, RWD, AWD/4WD, crawl control, regenerative braking, traction logic, and tank-turn maneuvering.
Modular energy and mobile power
Removable high-capacity batteries support range scaling, service, fleet rotation, and auxiliary loads for tools, sensors, lighting, refrigeration, mobile workstations, and partner modules.
Software-defined controls
A modular, development-ready controls architecture lets UPT adapt drive behavior, diagnostics, accessory logic, user interfaces, remote features, and partner-specific operating modes.
Reconfigurable steering and chassis kinematics
Suspension, steering, scrub radius, leverage, shock behavior, wheel travel, and compact turning behavior are treated as configurable platform systems, not isolated vehicle parts.
Validation and simulation layer
Route simulation, CAD, FEA, Matlab-based suspension studies, prototype testing, and configuration-specific validation help partners understand whether a UPT build can perform the mission.
Battery system & mobile power
A high-capacity battery platform that also powers the job.
UPT is designed as a compact electric vehicle and a mobile energy platform. Beyond driving the wheels, its battery architecture can support compatible tools, electronics, lighting, refrigeration, sensors, robotics, mobile workstations, and partner-developed modules.
Dual battery configurations provide up to 5.7 kWh of onboard energy. The auxiliary 48 V output can support compatible external loads up to 2.4 kW, depending on configuration, duty cycle, and thermal limits.

Powertrain & traction
Electric drive built for utility, control, and maneuverability.
UPT uses a distributed drive system — one motor and one controller per wheel. That makes the platform more adaptable than a conventional single-motor drivetrain and opens control strategies valuable for work, mobility, and tight-space operation.
Performance and drive figures shown here are configuration-dependent. The platform is presented to show engineering capability — it does not imply one universal legal or performance configuration. Final values vary by market, regulation, use case, and selected modules.
Selectable drive layout
FWD for tight maneuvering, RWD for efficient cruising, and 4WD/AWD for traction, payload movement, and uneven terrain — switched from the console with no mechanical drivetrain to engage.
Tank-turn capability
Left and right side wheels can be driven in opposite directions to pivot the platform in place on suitable surfaces — 0 m turning radius for warehouse aisles, corridors, and tight trail turns.
Drive modes
Eco, Standard, and Performance profiles let the same platform prioritize range, balanced daily use, or demanding work cycles.
Crawl & cruise control
Low-speed crawl supports precise positioning; cruise control supports longer campus, resort, trail, and patrol routes.
Vehicle Control Unit
The brain of UPT: smart control for a configurable EV platform.
UPT's VCU coordinates drive mode selection, traction control, regenerative braking, electronic parking brake, motor controller communication, diagnostics, and future software-enabled features through a modular, development-ready, and future-ready controls architecture.
CANBUS control
Real-time communication across motor controllers, battery systems, dashboard, and electronic control modules.
Modular control architecture
Development-ready logic adapts drive behavior, steering/drive controls, accessory functions, diagnostics, and partner-specific configuration rules.
Robotics-ready direction
Remote-control, unmanned operation, AI/autonomy integration, and fleet-dashboard pathways can be developed with partners.
Chassis & mounting
Engineered to be reconfigured.
The UPT chassis uses standardized mounting logic across the platform, so partners can add cargo bodies, seats, racks, sensors, tool mounts, canopies, bumpers, or application-specific modules without redesigning the entire small-footprint vehicle. Its reconfigurable steering and drive control architecture can adapt the vehicle behavior to different layouts, duty cycles, and operating environments.
Foldable bumper and rack concepts
Long-item support, front stand/rack functionality, and accessory mounting can be developed by configuration.
T-slots across the frame
Useful for racks, tool carriers, sensors, body panels, test fixtures, and custom partner modules.
IP67 protected main chassis block
The main lower chassis block protects the battery and electronics so they stay safe and functional across demanding environments, subject to configuration and maintenance.
Adjustable wheelbase and track
The platform can be dimensioned for compact storage, stability, payload, or application packaging.
Reconfigurable steering and drive control
Steering layout, drive mode, speed behavior, low-speed control, and traction response adapt to the intended UPT configuration.
Suspension & steering kinematics
Compact packaging, predictable handling, and tunable terrain behavior.
UPT's suspension and steering systems are engineered using kinematic modelling, hardpoint definition, wheel-travel curves, steering-ratio analysis, Ackermann behavior, tie-rod force estimates, and configuration comparison between development generations. The goal is not to expose every engineering detail, but to demonstrate that UPT is designed with measurable suspension, steering, load-transfer, and handling targets.
Wheel geometry through suspension travel
Bump steer and toe control
Configurable shock tuning
Steering ratio and low-speed maneuverability
120 mm suspension travel
A flat double-wishbone layout targets compact packaging with useful wheel travel for urban, utility, and uneven-surface operation.
Low scrub-radius target
The steering model evaluates torque-steer / kickback sensitivity by studying scrub radius and single-wheel drive/brake force.
Future tuning path
Optional steering-geometry optimization, anti-roll-bar tuning, tilt-steering, four-wheel steering, and configuration-specific control logic can be developed for future UPT variants.
Performance simulator
Don't guess the range. Simulate the mission.
The UPT simulator is a Google Maps based performance tool that lets you model routes, drive cycles, speed, terrain, temperature, load, and vehicle configuration to estimate whether a specific UPT-based vehicle can do the job. Instead of a generic maximum-range claim, fleets simulate their own daily use case.
Route grade
Use map-based elevation and road profile to test energy demand.
Payload / load
Estimate how passenger, cargo, and equipment loads affect range.
Temperature
Model battery and efficiency sensitivity under real operating climates.
Drive cycle
Compare city, campus, off-road, stop-and-go, and route-specific use cases.
