MG ZS EV vs Mazda CX-5 2.5: Which Should You Buy in 2025?

The MG ZS EV costs R650,000 to buy but will save you R195,386 over five years compared to the R750,000 Mazda CX-5 2.5 — that’s R3,256 back in your pocket every month, thanks to electricity costing half what petrol does and maintenance bills dropping by two-thirds.

The Real Cost: 5-Year Ownership Analysis

The MG ZS EV costs R650,000 upfront compared to the Mazda CX-5 2.5’s R750,000, but total cost of ownership flips that equation on its head.

Fuel Costs Breakdown

• MG ZS EV electricity cost: R12,143/year = R60,714 over 5 years
• Mazda CX-5 2.5 petrol cost: R26,220/year = R131,100 over 5 years
• Fuel savings with EV: R70,386 over 5 years

These calculations assume 15,000 km driven per year, an electricity tariff of approximately R2.50/kWh for home charging, and petrol prices around R23.50/litre. The MG ZS EV consumes roughly 16.2 kWh/100 km in real-world conditions, while the Mazda CX-5 2.5 averages 8.5 litres/100 km on the combined cycle.

Maintenance Costs

• MG ZS EV: R15,000 (minimal — no oil changes, less brake wear)
• Mazda CX-5 2.5: R40,000 (regular servicing, oil, filters, etc.)
• Maintenance savings with EV: R25,000

Electric vehicles require significantly less maintenance because they have fewer moving parts. There’s no engine oil to change, no exhaust system to repair, and regenerative braking means brake pads last far longer. The MG ZS EV typically needs only tyre rotations, brake fluid checks, and cabin air filter replacements during its first five years.

Who Should Buy the MG ZS EV?

The MG ZS EV is perfect for you if:

• Budget-conscious long-term: Save R3,256 per month on running costs
• Home charging available: Wake up to a “full tank” every morning for just R1,012/month
• City/suburban driving: Perfect for the 320 km range on a single charge
• Low maintenance priority: No oil changes, no exhaust systems, minimal brake wear
• Environmental responsibility: Zero tailpipe emissions in SA’s cities
• Modern technology: Latest infotainment, over-the-air updates, advanced safety features

The MG ZS EV suits South African families who do most of their driving within urban areas. If your daily commute is under 100 km and you can charge at home overnight, you’ll rarely need to use public charging infrastructure. The vehicle’s 44.5 kWh battery takes approximately 7 hours to charge from empty using a standard 7 kW home wallbox.

Real-World EV Ownership in South Africa

Many South African EV owners report that range anxiety disappears within the first month of ownership. The routine becomes simple: plug in when you get home, unplug when you leave. For most drivers, this means never visiting a petrol station again for daily driving.

During load shedding, EV owners with home charging can time their charging sessions between outages or invest in solar panels with battery storage for complete energy independence. This flexibility has become increasingly valuable as South Africa’s electricity landscape evolves.

Who Should Buy the Mazda CX-5 2.5?

The Mazda CX-5 2.5 makes sense if:

• Lower upfront cost needed: R100,000 cheaper to purchase
• Long-distance flexibility: Refuel anywhere in 5 minutes with petrol stations everywhere
• Heavy towing/off-road: 2.5L engine provides proven capability
• Rural/remote areas: No charging infrastructure concerns
• No home charging option: Petrol stations remain more accessible for now
• Familiar technology: Comfortable with traditional vehicle ownership

The Mazda CX-5 2.5 remains a solid choice for drivers who frequently travel long distances between cities, especially in areas where charging infrastructure is still developing. Its 56-litre fuel tank provides a range of approximately 650 km on a single fill, making it ideal for road trips to the Kruger Park, Garden Route, or other destinations where charging stations may be sparse.

Petrol Vehicle Advantages

For drivers who regularly cover more than 300 km per day or live in areas without reliable electricity supply, the Mazda CX-5 2.5 offers peace of mind. You can refuel at any of South Africa’s thousands of petrol stations in under five minutes, and there’s no need to plan charging stops on long journeys.

The CX-5 2.5 also excels at towing caravans or trailers, with a braked towing capacity that makes it suitable for weekend getaways with boats or camping equipment. While EVs can tow, their range decreases significantly under load, making petrol vehicles more practical for regular towing duties.

Key Decision Factors

Choose the MG ZS EV if you:

• Drive less than 320 km per day on average
• Have access to home charging or workplace charging
• Want to save R3,256 per month on running costs
• Prioritise lower maintenance and running costs
• Want zero tailpipe emissions
• Can manage the higher upfront cost

Choose the Mazda CX-5 2.5 if you:

• Need maximum flexibility for long-distance travel
• Don’t have reliable charging access
• Drive more than 320 km daily
• Need to minimise upfront costs
• Prefer the familiarity of petrol stations
• Live in an area with limited charging infrastructure

Charging Infrastructure in South Africa

South Africa’s EV charging network is growing rapidly. Major cities like Johannesburg, Cape Town, Durban, and Pretoria have excellent coverage, with charging stations at shopping centres, hotels, and office parks. GridCars, one of the country’s leading charging network providers, has installed fast chargers along major routes including the N1, N2, and N3 highways.

Home charging transforms EV ownership: Installing a home charger (R15,000–R30,000) gives you a “full tank” every morning at a fraction of petrol costs. Most EV owners charge overnight during off-peak hours when electricity rates are lowest, further reducing running costs. If you have solar panels, you can charge for free during the day, eliminating fuel costs entirely.

Public DC fast chargers can add 80% charge in 40–60 minutes, making them practical for longer journeys. However, the vast majority of EV charging happens at home, where you simply plug in when you arrive and unplug when you leave the next morning.

Planning Long-Distance Trips

The key to successful long-distance EV travel in South Africa is planning your charging stops in advance. Apps like PlugShare and GridCars show real-time charger availability and allow you to reserve charging slots during peak travel periods.

For example, the drive from Johannesburg to Durban (570 km) requires one charging stop for the MG ZS EV. Most drivers stop at the Harrismith GridCars fast charger, which adds 200 km of range in about 30 minutes—just enough time for a coffee break and leg stretch.

Long-Term Value

Over 5 years of ownership (15,000 km/year):

• Total savings with MG ZS EV: R195,386
• Monthly savings: R3,256
• Cost per kilometre – MG ZS EV: R9.68
• Cost per kilometre – Mazda CX-5 2.5: R12.28

These savings become even more significant when you consider potential load shedding. Many EV owners install solar panels and battery storage, allowing them to charge their vehicles even during power cuts. This energy independence provides additional value that’s difficult to quantify but increasingly important in South Africa’s current electricity landscape.

Resale values for EVs are also improving as the second-hand market matures. Early concerns about battery degradation have proven largely unfounded—most EV batteries retain 80–90% of their capacity after five years, and many manufacturers offer 8-year battery warranties for peace of mind.

Hidden Costs to Consider

While the MG ZS EV offers substantial savings, factor in the cost of home charger installation (R15,000–R30,000) if you don’t already have one. This one-time expense pays for itself within the first year through fuel savings, but it’s an important upfront consideration.

The Mazda CX-5 2.5, meanwhile, may require more frequent servicing as it ages. Oil changes, spark plugs, timing belts, and other consumables add up over time. Budget for approximately R8,000 per year in maintenance costs from year three onwards.

Environmental Impact

By choosing the MG ZS EV over the Mazda CX-5 2.5, you’ll prevent approximately 13,167 kg of CO₂ from entering the atmosphere over 5 years. This calculation accounts for South Africa’s current electricity grid mix, which includes coal, renewable energy, and other sources.

As South Africa transitions to cleaner energy sources—with major investments in solar and wind power—the environmental benefits of EVs will only increase. Even today, driving an EV in SA produces fewer lifetime emissions than a petrol vehicle, and that gap widens every year as the grid becomes greener.

Beyond Carbon Emissions

EVs also eliminate local air pollution in cities. Unlike petrol vehicles, they produce zero tailpipe emissions, improving air quality in congested urban areas. This benefit is particularly significant in Johannesburg and Pretoria, where air pollution from vehicle emissions contributes to respiratory health issues.

Noise pollution is another often-overlooked benefit. EVs operate almost silently at low speeds, reducing noise in residential areas and making cities more pleasant places to live.

The Verdict

Clear Winner: MG ZS EV

The numbers speak for themselves. Despite the higher purchase price, the MG ZS EV will save you a staggering R195,386 over 5 years compared to the Mazda CX-5 2.5. That’s R3,256 per month back in your pocket.

If you have access to home charging and drive within the 320 km daily range, the MG ZS EV is the smarter financial choice. The fuel and maintenance savings alone make it worthwhile. You’ll also enjoy a quieter, smoother driving experience with instant torque and modern technology features.

However, the Mazda CX-5 2.5 remains a practical option for drivers who regularly travel long distances, live in areas with limited charging infrastructure, or need the flexibility of quick refuelling at any petrol station. Both vehicles offer excellent build quality, safety features, and reliability—your choice ultimately depends on your specific driving patterns and charging access.

Making Your Decision

Start by honestly assessing your daily driving needs. Track your mileage for a month to see how far you actually drive each day. Most South Africans will find that 90% of their journeys are well within the MG ZS EV’s 320 km range.

Next, evaluate your charging options. Do you have off-street parking where a home charger can be installed? Is there workplace charging available? If you answer yes to either question, the MG ZS EV becomes significantly more practical.

Finally, consider your budget. While the MG ZS EV costs R100,000 less upfront than the Mazda CX-5 2.5 in this comparison, you’ll need to factor in charger installation costs. However, the monthly savings of R3,256 mean you’ll break even within months and enjoy pure savings thereafter.
