Kia EV6 vs Mazda CX-5 2.5: Which Should You Buy in 2025?

Considering switching to an EV? This comprehensive comparison between the Kia EV6 and the Mazda CX-5 2.5 will help you make the right decision for your wallet and lifestyle in South Africa. We’ve analysed purchase price, running costs, maintenance, and total cost of ownership over 5 years to give you the complete financial picture.

📊 Quick Comparison Overview

💰 The Real Cost: 5-Year Ownership Analysis

The numbers reveal an important truth about EV ownership in South Africa today. While the Kia EV6 costs R1,100,000 upfront compared to the Mazda CX-5 2.5’s R750,000, that R350,000 price premium significantly impacts total cost of ownership. Despite substantial savings on fuel and maintenance, the EV still costs R250,521 more over 5 years—approximately 27% higher than the petrol alternative.

Understanding the Purchase Price Gap

The R350,000 difference in purchase price is the single biggest factor in this comparison. This premium reflects the current state of EV pricing in South Africa, where battery costs and import duties keep electric vehicles significantly more expensive than their petrol equivalents. For many South African households, this represents a substantial barrier to EV adoption, regardless of the running cost savings.

Fuel Costs Breakdown

Here’s where the EV shines. Based on 15,000km annual driving:

• Kia EV6 electricity cost: R11,324/year = R56,621 over 5 years (at R2.50/kWh home charging rate)
• Mazda CX-5 2.5 petrol cost: R26,220/year = R131,100 over 5 years (at R24/litre)
• Fuel savings with EV: R74,479 over 5 years

The EV’s efficiency advantage is clear: charging at home costs roughly R944 per month versus R2,185 per month for petrol. That’s a monthly saving of R1,241 on fuel alone. However, this R74,479 saving over 5 years only offsets about 21% of the R350,000 purchase price premium.

Maintenance Costs

EVs have a significant maintenance advantage due to fewer moving parts:

• Kia EV6: R15,000 (minimal—no oil changes, less brake wear, no exhaust system)
• Mazda CX-5 2.5: R40,000 (regular servicing, oil changes, filters, brake pads, etc.)
• Maintenance savings with EV: R25,000

The EV’s regenerative braking system means brake pads last significantly longer, and there’s no engine oil, timing belts, or exhaust systems to maintain. This R25,000 saving is substantial, but again, it only recovers about 7% of the purchase price premium.

The Total Cost Reality

When you add everything together:

• Combined fuel and maintenance savings: R99,479 over 5 years
• Purchase price premium: R350,000
• Net additional cost for EV: R250,521 over 5 years
• Monthly cost difference: R4,175 more for the Kia EV6

This means that despite the EV’s lower running costs, you’re paying an extra R4,175 per month over 5 years compared to the Mazda. For context, that’s enough to cover a car payment on a R200,000 vehicle, or a significant portion of many South African households’ monthly budgets.

🎯 Who Should Buy the Kia EV6?

The Kia EV6 makes sense for you if:

• 💰 Long-term ownership planned: If you keep the vehicle for 8-10 years, ongoing fuel savings will eventually offset the purchase premium

🔋 Charging Infrastructure in South Africa

South Africa’s EV charging network is growing rapidly, with over 500 public charging points nationwide. Major cities like Johannesburg, Cape Town, Durban, and Pretoria have excellent coverage, though load-shedding remains a consideration for EV owners who rely on public charging during outages.

Home charging is the game-changer: Installing a home charger (R15,000-R30,000) gives you a “full tank” every morning at a fraction of petrol costs. However, this additional upfront investment should be factored into your decision—it adds to the already substantial R350,000 purchase price premium.

For apartment dwellers or those without dedicated parking, the lack of home charging makes EV ownership significantly less practical. Public charging is more expensive (R4-R6/kWh vs R2.50/kWh at home) and less convenient, eroding much of the EV’s cost advantage.

📈 Long-Term Value Considerations

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

• Total cost advantage—Mazda CX-5 2.5: R250,521 less expensive
• Monthly cost difference: R4,175 more for the Kia EV6
• Cost per kilometre—Kia EV6: R15.62
• Cost per kilometre—Mazda CX-5 2.5: R12.28

The Mazda’s lower total cost of ownership reflects the reality that EV purchase prices in South Africa haven’t yet reached parity with equivalent petrol vehicles. The R350,000 premium is simply too large for the R99,479 in fuel and maintenance savings to overcome within a typical 5-year ownership period.

When Does the EV Break Even?

If you continue the same driving pattern beyond 5 years, the ongoing fuel and maintenance savings of R19,896 per year will gradually close the gap. At this rate, you’d need to keep the EV for approximately 12-13 years before the total cost of ownership equals the Mazda. This assumes stable electricity and petrol prices, which is a significant assumption given South Africa’s energy landscape.

For buyers who typically keep vehicles for 8-10 years, the gap narrows considerably but the EV still costs more overall. Only those planning very long-term ownership (12+ years) will see the EV become financially competitive.

🌍 Environmental Impact

By choosing the Kia EV6 over the Mazda CX-5 2.5, you’ll prevent approximately 13,167kg of CO₂ from entering the atmosphere over 5 years (based on 75,000km total driving). For environmentally conscious buyers, this benefit may justify the R250,521 higher total cost of ownership—effectively paying about R19 per kilogram of CO₂ prevented.

It’s worth noting that South Africa’s electricity grid is still heavily coal-dependent, so EVs aren’t completely emissions-free when you account for electricity generation. However, they still produce significantly fewer emissions than petrol vehicles over their lifetime, and this advantage will improve as our grid incorporates more renewable energy.

💭 Understanding the True Cost

It’s important to understand what these numbers mean for your budget. The Kia EV6 saves you R99,479 in fuel and maintenance over 5 years—a substantial amount. However, its R350,000 higher purchase price means you’re still R250,521 out of pocket compared to the Mazda. That’s approximately 27% more expensive over the ownership period, or R4,175 extra per month.

For many South African families, this represents a significant premium to pay for environmental benefits and modern technology. The question becomes: are zero emissions, cutting-edge features, and lower monthly running costs worth an extra R250,521 to you?

The Opportunity Cost

Consider what else you could do with R250,521 over 5 years:

• Invest it at 8% annual return: worth approximately R368,000 after 5 years
• Pay down a home loan: save significant interest over the loan term
• Fund a child’s education or build an emergency fund
• Upgrade other aspects of your lifestyle

This opportunity cost is real and should factor into your decision, especially if you’re stretching your budget to afford the EV.

🏁 The Verdict

The Mazda CX-5 2.5 Wins on Pure Economics

If you’re making a purely financial decision, the Mazda CX-5 2.5 is the clear winner, costing R250,521 less over 5 years. That’s real money—27% less expensive—that could go toward other financial priorities. For budget-conscious buyers, families managing tight monthly budgets, or anyone prioritizing total cost of ownership, the Mazda is the rational choice.

But the Kia EV6 Offers Intangible Benefits

The R4,175/month premium (R250,521 over 5 years) buys you:

• Zero tailpipe emissions and environmental peace of mind
• Cutting-edge technology and a premium, quiet driving experience
• Lower monthly running costs (R944 vs R2,185 for fuel)
• Minimal maintenance hassles—no oil changes or exhaust repairs
• Future-proofing as SA’s charging infrastructure expands and petrol prices rise

For some buyers, these benefits justify the premium. If you’re passionate about reducing your carbon footprint, value the latest technology, have reliable home charging, and can comfortably afford the higher total cost, the EV delivers a superior ownership experience despite costing more.

Your Decision Framework:

• Choose the Mazda CX-5 2.5 if minimizing total cost is your top priority, you need maximum flexibility, or you lack home charging access
• Choose the Kia EV6 if environmental impact and modern technology justify paying R250,521 more, you have home charging, and you plan very long-term ownership (10+ years)

Both are excellent vehicles—your choice depends on whether the EV’s benefits are worth R250,521 to you over 5 years. For most South African buyers focused on value, the Mazda’s 27% lower total cost makes it the more sensible choice. For environmentally conscious buyers with higher budgets and long-term ownership plans, the Kia EV6 offers a glimpse of the future.
