What Does It Really Cost to Drive an EV in South Africa? A 104 km Real-World Test

Electric vehicle efficiency is often discussed in terms of laboratory figures, claimed range and battery capacity. But what does an EV actually consume when you drive it in the real world? To find out, we took an EV on a 104 km round trip through Cape Town, combining freeway cruising, traffic, acceleration, rolling hills and one of the city's more demanding climbs — Ou Kaapse Weg. The objective was simple: measure the real-world energy consumption, see how much energy regenerative braking puts back into the battery, and then calculate what the journey actually costs. 18.1 kWh per 100 km in the real world The journey finished with an average consumption of just 18.1 kWh per 100 km. That figure included everything the route could throw at the car — freeway driving at around 100–120 km/h, traffic, acceleration, hills and the climb over Ou Kaapse Weg. One of the most interesting observations was how dramatically consumption changes depending on what the car is doing. During acceleration, the vehicle can briefly demand more than 50 kW of power. Once cruising at a steady speed, however, the power requirement drops dramatically. On downhill sections, the opposite happens. Instead of consuming significant energy, the car begins recovering energy through regenerative braking. The mountain makes the difference The climb over Ou Kaapse Weg provided a great demonstration of how much energy is required to move a roughly 2.5-ton vehicle uphill. As the car climbed, instantaneous power demand rose above 50 kW. At the summit, however, the story changed. As the vehicle descended the other side of the mountain, regenerative braking began feeding energy back into the battery. Instead of turning the vehicle's potential energy into heat through the conventional brakes, the electric drivetrain converts much of that energy back into electrical energy. That recovered energy then contributes to the overall efficiency of the journey. The GPS got it right At the start of the journey, the vehicle's GPS estimated that we would arrive at our destination with 52% battery remaining. After completing the 104 km round trip, we arrived home with exactly 52% remaining. That is a pretty impressive demonstration of how accurately modern EV range prediction can reflect real-world driving conditions. And then there's the sunshine This is where the story becomes particularly interesting. The vehicle isn't simply charged from the electricity grid. Back at home, the EV is connected to a Fox ESS EV Charger, with the electricity supplied through the home's Fox solar-energy system. With Fox you're essentially driving on sunshine. ☀️ Fox ESS — powering the home, charging the car, and helping you drive on sunshine.
