Diesel Vs Electric – What Is The Best?

If you’re in the market for a new vehicle, chances are you’ve heard a lot about electric vehicles (EVs) lately. With the push towards greener transportation, EVs are gaining popularity, but diesel vehicles are still a solid option for many Kiwis. So, how do the two stack up against each other?

Let’s explore the key differences between diesel and electric vehicles to help you make the best decision for your needs.

1. Fuel Type: Petrol Station vs Charging Station

The most obvious difference between diesel and electric vehicles is what powers them. Diesel vehicles run on—you guessed it—diesel fuel, which you’ll find at most petrol stations across the country. EVs, on the other hand, run purely on electricity and need to be plugged into a charging station.

While New Zealand’s EV charging network is expanding, diesel still has the edge when it comes to the convenience of refuelling. If you live in a more rural area or frequently travel long distances, access to petrol stations is still far more widespread than EV chargers.

2. Running Costs: Fuel vs Power Bills

When it comes to running costs, EVs are the clear winner. Electricity is significantly cheaper than diesel fuel, and you’ll notice the savings immediately when charging your EV compared to filling up at the pump. The average cost to charge an EV at home in New Zealand is around $3 to $10 per 100 km, depending on your electricity plan. Diesel, on the other hand, is typically much more expensive per kilometre.

However, it’s worth noting that if you’re doing a lot of highway driving, diesel engines tend to be more fuel-efficient for long trips compared to petrol engines, so they can still offer good value for some drivers.

3. Environmental Impact: Cleaner and Greener?

There’s no doubt that EVs are the more environmentally friendly option. EVs produce zero emissions while driving, which means they contribute less to air pollution and help reduce New Zealand’s overall carbon footprint. As the country continues to increase its renewable energy production (like hydro, wind, and solar), EVs are becoming an even greener choice.

Diesel vehicles, on the other hand, produce emissions, and while modern diesel engines are more efficient and cleaner than they used to be, they still contribute to air pollution and greenhouse gas emissions. In cities like Auckland, where traffic congestion is an issue, diesel vehicles can worsen air quality.

4. Performance: Torque vs Instant Power

Diesel vehicles are known for their impressive torque, making them ideal for towing and off-road adventures. If you’re pulling a boat, caravan, or trailer, a diesel engine offers the kind of low-end power you need. That’s why you’ll still see many Kiwis opting for diesel-powered utes like the Ford Ranger and Toyota Hilux.

EVs, on the other hand, have instant power delivery, thanks to their electric motors. This means quicker acceleration and a smooth driving experience, particularly in urban environments. If you’re driving mostly in the city or enjoy a quick and responsive drive, an EV can offer a superior experience.

5. Maintenance: Fewer Parts vs Regular Servicing

Diesel engines are more complex than electric motors, which means they require more maintenance. You’ll need regular servicing, oil changes, and potentially costly repairs if something goes wrong with the engine or exhaust system. EVs, in contrast, have fewer moving parts, meaning less can go wrong. There’s no need for oil changes, and overall maintenance tends to be simpler and cheaper.

However, diesel vehicles are known for their durability and longevity. If properly maintained, they can last for many years and are well-suited for those who need a reliable workhorse.

6. Range: Long Distance vs Limited Charging Network

Diesel vehicles still have the upper hand when it comes to long-distance driving. With a full tank, a diesel vehicle can travel hundreds of kilometres before needing a refill, which is ideal for road trips and rural commutes.

While EVs are improving in terms of range, with many models now offering between 300 and 500 kilometres on a single charge, long-distance travel can still be a bit tricky in New Zealand, especially if you’re heading to remote areas where charging infrastructure is limited. Planning your journey around charging stations is essential with an EV.

7. Initial Cost: Diesel’s Price Advantage

Diesel vehicles generally have a lower upfront cost than EVs. While EV technology continues to advance and prices are slowly becoming more competitive, diesel cars, trucks, and utes are often the more affordable choice for those looking for power and range without breaking the bank.

Final Thoughts: Which One Should You Choose?

Choosing between a diesel and electric vehicle comes down to your specific needs and lifestyle. If you’re frequently travelling long distances, towing heavy loads, or living in a rural area, a diesel vehicle might still be the best choice for you. On the other hand, if you’re looking for lower running costs, a cleaner environmental impact, and a smoother city driving experience, an EV could be the way forward.

As more charging stations pop up across Aotearoa and battery technology improves, EVs are becoming a more practical choice for everyday Kiwi drivers. But diesel remains a strong contender for those needing power, range, and durability.
