While diesel cars are less expensive to buy upfront and have better torque, low running costs, less maintenance and better fuel economy make electric cars a smart purchase. With a network of charger stations that’s expanding every day, an electric car is increasingly looking like a more sensible purchase when compared to traditional combustion-engined transport.
Lower lifetime cost than gasoline
Longer lasting engine than petrol models
More efficient (by around 25% compared to petrol) making for cheaper refuelling cost
Less CO2 produced as a result of efficiency, leading to less road tax
Higher torque or pulling power (for better acceleration)
Lower depreciate than petrol or gasoline engines
Versatile engines which can handle various fuel types (e.g. biodiesels in future)
Pricier than gasoline, volatile fuel price
Less environmentally-friendly - emitting nitrous oxides, hydrocarbons, and particulates that are harmful to the environment
Higher insurance than for petrol engines
Higher repair costs than for petrol engines and electric motors
Zero emissions (except for grid-supplied generation)
Lower lifetime cost than diesel or gasoline
Little noise pollution and calm, quiet driving experience
No road tax or congestion charges
High residual value
Government incentives and tax breaks applicable
Lower maintenance costs (especially in comparison to internal combustion engines)
Higher upfront purchase price
Limited range on a single charge
Long recharge time
Scarcity of charging points
Danger to pedestrians (due to silent approach)

Diesel cars might cost less to buy or lease, however, lower running costs make EVs a more affordable and cost-effective purchase over the long run. They’re also easier and cheaper to maintain due to their fewer moving parts.
Most diesel cars have a cheaper purchase price than electric vehicles, leading many to believe they’re a more affordable investment. However, EVs are less expensive to run, something we’ll touch on in a moment.
The batteries produced for an electric car are pricey, which is what results in the hike in price tag. Furthermore, EVs often feature more advanced technology, something that also drives production costs, and therefore price, up.
As mentioned previously, the big advantage to going electric are running costs - EVs are more affordable to run due to lower prices for electricity.
In fact, diesel is one of the most expensive fuel types on the market. This is because diesel is taxed at a higher rate as it is considered a ‘dirtier’ kind fuel.
On the other hand, the widespread availability of electricity makes charging one of the cheapest ways to re-fuel. On average, it cost roughly £8.00 to charge a standard 200-miler plug-in at home, even less at a rapid charger, where you can top-up 100 miles of charge for around £6.50. Better yet, some chargers, such as those at workplaces, are completely free to use.
Filling a 50-litre diesel tank costs close to £60.00, whereas you could get a similar mileage with an EV for just £25.00.
All this makes running an EV much more cost effective than a vehicle with a diesel engine. And, between road tax and the various government grants available, there’s a lot more you stand to save as an EV owner.
The table below features models from the same popular brands and shows the difference in the running costs between diesel and electric models.
|Diesel model||Cost per mile||Electric models||Cost per mile|
|Vauxhall Corsa Turbo D SE||8.1 p||Vauxhall Corsa-E||4.6 p|
|Kia Sportage GDI||10.4 p||Kia E-Niro||4.5 p|
|Audi Q5 TDI||14.0 p||Audi E-Tron||6.9 p|
Traditional petrol and diesel vehicles contain over 100 moving parts. On the other hand, most EVs have a total of under 5 actual moving parts, making them much easier and less expensive to maintain. Regenerative braking also contributes to less wear and tear on the tyres and breaks of plug-in vehicles. Overall, this means that the cost of maintaining an EV over its lifetime will be much less than that of a conventional diesel car.
It would make sense that an all-electric car would be better for the environment than a combustion-engined vehicle, and this is true. In fact, when it comes to comparing electric cars to diesel-powered vehicles, there’s almost no competition; an EV is significantly more eco-friendly.
Figures from the European Environment Agency reveal that diesel engines emit on average 121.5 g/km of CO2 emissions. This is nearly one 1.5 times more than the EU’s 2020-21 target for new cars, which is 95 g/km.
One area where EVs do lose out is in manufacturing, as there are higher emissions produced in the build and assembly of an electric vehicle. However, when compared over a lifetime, plug-ins emit about half the emissions that gasoline cars produce.
EVs are also much quieter than diesel cars, which on-road tend to be markedly louder than petrol cars. The near-silent effect of electric batteries and motors leads to less noise pollution and a calmer, more comfortable ride.
