Introduction
The shift from traditional gasoline- or diesel-powered cars (Internal Combustion Engine — ICE) to hybrids (HEV / PHEV) and full Electric Vehicles (EVs) is accelerating. With this change come differences not just in how cars are fueled, but how they are maintained. Understanding these differences can help you save money, avoid surprises, and ensure your vehicle’s longevity.
ICE vs Hybrid vs EV: Basic Overview
| Type | How it Works | Key Components |
|---|---|---|
| ICE (Gasoline / Diesel) | Uses an internal combustion engine burning fuel. | Engine, transmission (multi-speed), exhaust system, many moving parts. |
| Hybrid (HEV / PHEV) | Combination of an ICE engine + one or more electric motors & battery. | ICE components + battery pack + electric motor(s) + cooling/control systems. |
| Electric Vehicle (EV / BEV) | Pure electric motor(s) powered by a battery pack. | Battery pack, electric motor(s), inverter, cooling system, charging system. |
Why Maintenance Needs Differ
Fewer moving parts — EV motors lack pistons, spark plugs, or exhaust systems, making them simpler.
Regenerative braking — Reduces brake pad wear compared to ICE vehicles.
Battery cooling — EVs and hybrids rely on effective thermal management systems.
Battery health — Owners must monitor charging habits, temperature, and battery state of health.
Tire wear — EVs are heavier and deliver instant torque, meaning tires need more frequent checks.
Fluid checks — EVs still require brake fluid, coolant, and occasionally transmission fluids.
Software updates — Diagnostics, firmware, and updates become part of routine servicing.
Repair costs — While routine maintenance is cheaper, out-of-warranty battery or electronic repairs can be costly.
Side-by-Side Maintenance Tasks
| Task | ICE | Hybrid | EV |
|---|---|---|---|
| Oil & filter | Frequent | Needed (less often) | Not applicable |
| Spark plugs | Yes | Yes (for ICE part) | Not applicable |
| Exhaust checks | Yes | Yes (for ICE part) | Not applicable |
| Brake pads | Regular wear | Less wear (regen braking) | Less wear (regen braking) |
| Battery system | 12V battery | ICE + hybrid battery | High-voltage battery pack |
| Cooling systems | Engine cooling | ICE + hybrid cooling | Electronics/battery cooling |
| Transmission fluids | Yes (multi-speed) | Special hybrid gearboxes | Minimal, single-speed gear |
| Tires | Standard | Higher wear | Higher wear |
| Software | Limited | More frequent | Frequent & critical |
Benefits & Challenges
Lower running costs: Fewer oil changes, less mechanical wear, fewer exhaust repairs.
Longer component life: Brakes and motors often last longer.
Specialist care required: High-voltage systems demand expert handling.
Potential high costs: Out-of-warranty battery or inverter replacements can be expensive.
Tips for Aussie EV & Hybrid Owners
Park in shaded areas to protect batteries from heat.
Use reliable chargers for stable power supply.
Rotate and align tires more frequently due to extra weight.
Service cooling systems before summer.
Keep software and firmware up to date.
Always choose a workshop trained in hybrid & EV systems.
Misconceptions
“EVs don’t need servicing” — They still need tire checks, fluid changes, and diagnostics.
“Batteries fail in 5 years” — Most last 8–10+ years with proper care.
“Hybrids cost more to maintain” — They can actually save money due to reduced engine workload.
Final Takeaway
EVs and hybrids simplify many traditional maintenance tasks but introduce new ones, especially around batteries, cooling, and software. With the right care, they can be cheaper and more reliable to maintain than ICE vehicles.
