Introduction
Vehicle roadtax prices vary whether you’re driving a diesel, hybrid or even full EV. These differences depend on engine type, cylinder capacity (cc), and current government policy. This article shows how to calculate for each type of vehicle, complete with comparison tables and simple examples.

1. How to Calculate Roadtax for Diesel Cars
Diesel cars typically have higher roadtax than petrol due to carbon emissions and engine noise.
Basic formula (JPJ example):
Roadtax = Base rate + [(Engine capacity – lower limit) × additional rate per cc]
Example: Diesel 2.0L
- Base rate: RM380
- Additional: RM0.50 × (2000 – 1800) = RM100
- Total roadtax: RM480/year
2. How to Calculate Roadtax for Hybrid Cars
Hybrids are still considered to have internal combustion engines (petrol), so roadtax is calculated like regular petrol cars.
Some models may enjoy government discounts under previous programs.
Examples:
- Toyota Corolla Cross Hybrid 1.8L → RM90 – RM120/year
- Honda City RS e:HEV → RM70 – RM90/year
3. How to Calculate Roadtax for Electric Vehicles (EV)
EVs do not have engine capacity (cc), so conventional formulas do not apply.
Instead, EVs are fully exempt from roadtax until 31 December 2025.
After the exemption period, new rates are expected based on electric motor power (kW).
4. Roadtax Comparison Table by Vehicle Type
| Vehicle Type | Calculation Method | Estimated Annual Roadtax | Notes |
| Diesel 2.0L | Based on cc + additional rate | RM400 – RM600 | Highest rate |
| Hybrid 1.8L | Based on cc | RM90 – RM120 | Same as petrol |
| EV | No calculation (special exemption) | RM0 | Exempt until 2025 |
