Cascadia Motion EV Drive System Kits
We’re excited to present four of our top-tier, ready-to-install powertrain solutions from Cascadia Motion—designed to take your classic car or restomod project to the next level. Each kit combines high-performance motors, inverters, control systems and pre-wired harnesses, but they differ in power output, architecture and target applications.
This page helps you compare them side-by-side, so you can pick the right fit for your goals.
SS-250 / CM200 / Divorced Inverter Complete EV Drive System (300 HP), $42,250A flexible configuration that separates the inverter from the motor (“divorced inverter”), offering enhanced cooling options and adaptability for custom installations. |
iM-225 Complete EV Drive System (300 HP), $35,710A compact, integrated motor/inverter module with liquid cooling, designed for high performance in tighter engine bays. |
iDM-190 Complete EV Drive System (300 HP), $41,200A design-optimized variant that offers efficient packaging and balanced performance for classic car builds. |
iM-375 Complete EV Drive System (500+ HP), $50,200The high-power solution for those aiming for extreme performance builds, offering more than 500 HP for sports cars, high-end restomods or performance conversions. |

| Best For | Classic builds < 3,000 lbs | Tight engine bays | Custom layouts, lightweight racers | High-power conversions > 400 HP |
*Peak power is short-duration (≈30 s). Continuous ratings depend on voltage, cooling and duty cycle. Data compiled from Cascadia Motion documentation and verified distributor sources.
Summary of Differences
- Power Range: iM-225 / iDM-190 sit in the ~300 HP class; SS-250 and iM-375 push into 350–500 HP.
- Integration: iM- and iDM-series are fully integrated, while SS-250 offers divorced inverter flexibility.
- Voltage & Complexity: Higher-power systems (SS-250, iM-375) demand higher voltage batteries and more cooling capacity.
- Fitment: iDM-190 suits compact cars, SS-250 suits custom layouts, and iM-375 suits premium performance builds.
Key takeaways
If you’re looking for a balanced 300 HP class conversion with relatively “straightforward” packaging, the iM-225 or iDM-190 are excellent.
If your build demands flexibility in inverter placement (e.g., tight engine bay, remote inverter location), the SS-250 / divorced inverter architecture gives you more freedom.
For elite performance and a build that wants ~500 HP class power, the iM-375 is the step-up — but it comes with higher system demands (battery voltage, cooling, integration).
Packaging constraints (motor weight/size), voltage system (400–480 V vs 700+ V), and system complexity (integrated vs separated inverter) are the major differentiators.
