Though the diesel variant has a higher torque than the petrol, it does so at a lower RPM due to which shifting is necessary sooner than that on the petrol. Thus the petrol produces more power and accelerates from 0 to 100 quicker.
Diesel engines last longer than petrol ones. Diesel is a light oil and when burned and used as fuel by the vehicle it lubricates the parts of the engine. This prolongs the life of the engine. diesel engines can run for 1,000,000-1,500,000 miles before needing any major diesel repairs. If kept well-maintained, a diesel engine can be driven for about 30 years or more.
Petrol is a detergent and washes away oil from the components of the engine, therefore, wearing it out quicker.
But, Diesel fuel usually costs more. Servicing can be more expensive, although you don’t need to do it as often. Diesel cars produce a lot more NO2. Diesel engines can be slightly noisier.
The maintenance cost of diesel cars is higher than petrol cars. This is because consumables like engine oil and spares used in diesel vehicles are more expensive.
Petrol is expensive when compared to diesel and adds to the running cost of the car over the years. Also, because of the volatility of petrol, mileage of the car also suffers. Petrol engines tend to clog up quickly and require maintenance more frequently.
Coming to resale value, since the life of a diesel car is more, the resale value continues to be better than the petrol counterpart. The diesel variant is costlier than a used car of the same make powered by petrol.

Determining whether a diesel or petrol car is better depends on various factors, including individual preferences, driving habits, environmental considerations, and financial considerations. Here’s a comparison of the two:
Petrol Cars:
Cost: Petrol cars are typically less expensive to purchase compared to diesel cars. Additionally, petrol fuel tends to be cheaper than diesel in many regions.
Performance: Petrol engines generally offer smoother acceleration and better high-speed performance compared to diesel engines. They are often preferred for sporty driving characteristics.
Emissions: Petrol cars typically produce fewer nitrogen oxide (NOx) emissions compared to diesel cars. However, they may emit higher levels of carbon dioxide (CO2) and other greenhouse gases.
Noise and Vibration: Petrol engines are generally quieter and smoother compared to diesel engines, especially at lower speeds. This can contribute to a more comfortable driving experience.
Maintenance: Petrol engines usually require less frequent maintenance compared to diesel engines. They may have lower maintenance costs over the vehicle’s lifetime.
Diesel Cars:
Fuel Efficiency: Diesel engines are typically more fuel-efficient than petrol engines, especially at highway speeds and under heavy loads. This can result in lower fuel costs over time for long-distance or high-mileage drivers.
Torque: Diesel engines produce higher levels of torque at lower engine speeds, making them well-suited for towing, hauling, and driving in hilly terrain. They offer better low-end power compared to petrol engines.
Longevity: Diesel engines are known for their robustness and durability. With proper maintenance, they can often last longer than petrol engines, making them a preferred choice for commercial vehicles and long-term ownership.
Resale Value: Diesel cars may have higher resale value compared to petrol cars, especially in regions where diesel vehicles are in demand or where diesel fuel is significantly cheaper than petrol.
Emissions: While modern diesel engines are cleaner than older models, they still tend to emit higher levels of particulate matter (PM) and NOx emissions compared to petrol engines. This can contribute to air pollution and negative health effects in urban areas.
Ultimately, the choice between a diesel and petrol car depends on individual priorities, driving needs, and environmental considerations. It’s essential to weigh the pros and cons of each option and consider factors such as fuel costs, maintenance expenses, resale value, and environmental impact before making a decision. Additionally, advancements in hybrid and electric vehicle technology offer alternative options for environmentally conscious consumers.
