Keep the essentials.
Preserves the OEM engine, drivetrain, and emissions system.
INTRODUCING MCOY RHEV™
Your car.
A more electric future.
Keep the car you love. Add electric power.
A practical new path to lower vehicle emissions.
RETROFIT HYBRID ELECTRIC VEHICLEBuilt around what's already on the road.
01 / A DIFFERENT WAY FORWARD
The case for retrofitThe next chapter
doesn't need
a new car.
Millions of working vehicles have years of life left. Electrification shouldn't have to wait for them to be replaced.
Mcoy is developing a retrofit hybrid system that brings electric assist to existing vehicles—preserving what works while changing how we move forward.
5–15years
of usable life often remain in the vehicles people already own.1
02 / MEET THE RHEV SYSTEM
Patent-pending architectureMore electric.
Less disruption.
An electric hub motor, a trunk-mounted LFP battery, and integrated electronics. Designed to work alongside the original engine and drivetrain.
ORIGINAL POWERTRAIN + ELECTRIC ASSISTAdd electric assist.
A dedicated hub motor and LFP battery bring hybrid capability to an existing vehicle.
Simplify the install.
Designed for minimal vehicle modification and a standardized, one-day installation.
Development objectives shown. Vehicle compatibility, installation time, and regulatory pathway remain subject to validation.
03 / FROM CONCEPT TO THE ROAD
Engineering in progress
THE TRL 4 PROTOTYPE / MCOY MOTORSCURRENT MILESTONE — TRL 4
A real vehicle.
A working start.
The prototype has demonstrated hybrid-assist operation in a production vehicle and confirmed non-invasive integration.
- Production-vehicle integration
- Demonstrated hybrid assist
- Original vehicle systems preserved
Performance and emissions reductions will be quantified during further testing. Results will vary by vehicle, duty cycle, and usage.
04 / THE ROAD AHEAD
Planned development pathStart local.
Build for scale.
01
Validate
Advance the prototype and validate the testing and regulatory pathway.
02
Demonstrate
Progress through beta deployment and certification work.
03
Launch
Establish a Southern California installation and training facility.
04
Expand
Grow through a certified network of automotive service providers.
A FASTER PATH TO CUTTING VEHICLE EMISSIONS
The future is electric.
Let's bring today's cars along.
