Compare the running costs of Petrol, Diesel, and Electric vehicles in the South African market.
With global energy markets facing unprecedented volatility, South African motorists are trapped in a cycle of unpredictable monthly expenses. The frustration isn't just about the "pump shock" during monthly price adjustments; it's the hidden cost of efficiency loss. Traditional Petrol and Diesel engines (Internal Combustion Engines or ICE) are inherently inefficient, converting only about 20% to 30% of the energy in fuel into actual movement. The rest is wasted as heat.
Furthermore, maintenance costs for diesel vehicles—specifically diesel particulate filters (DPF) and complex turbo systems—often spike as the vehicle ages. For those moving between city traffic and long-distance highway hauls, calculating whether a premium diesel or a high-octane petrol is more "economical" has become a complex mathematical headache. Without a clear comparison against modern Electric Vehicles (EVs), consumers are often blind to the potential 70% reduction in "per kilometer" costs that electricity offers, even at current Eskom or municipal rates.
| Vehicle Type | Cost per Month |
|---|---|
| Petrol (8L/100km) | R 0.00 |
| Diesel (6L/100km) | R 0.00 |
| Electric (18kWh/100km) | R 0.00 |
This tool addresses the "Job to be Done" of financial predictability. By simplifying the energy density of fuel versus the efficiency of electric motors, you can make an informed decision based on your specific driving habits. The calculator uses real-world averages for South Africa: petrol vehicles at 8L/100km, diesel at 6L/100km, and modern EVs at 18kWh/100km.
Switching to an EV doesn't just lower the cost per kilometer; it decouples your mobility from the Brent Crude oil price. Even with municipal electricity price hikes, the energy-to-motion efficiency of an electric motor (often exceeding 90%) means that for every Rand spent, you travel significantly further. This tool provides the "Economic Proof" required for fleet managers and private owners to justify the higher upfront capital expenditure of an EV through massive operational expenditure (OPEX) savings.
Before: Spending R3,600/pm on a petrol sedan driving from Sandton to Pretoria.
After: Switching to an EV reduces monthly energy spend to R945, saving over R31,000 annually.
Before: Light delivery vehicles (Diesel) averaging R4,500 in fuel costs.
After: Moving to electric delivery vans reduces "fuel" costs by 65%, significantly improving thin profit margins.
Before: Paying R2,500 for petrol despite having excess solar generation at home.
After: Charging the EV from solar at R0.00 effective cost, eliminating transport fuel costs entirely.
