While petrol engines were once considered to be the best for the segment, diesel engines have made strong inroads over the last couple of decades. Diesel engines were once considered as parts only worthy of trucks and taxis, this mentality has changed and fast. Available in almost every variant, diesel engines have made massive leaps in technology. Increased refinement and increased cubic capacity (cc) makes them ideal when coupled with the variety of benefits they provide.
Petrol engines, however, have always been some of the most powerful and best functioning in the world. Considered ideal for cars, many luxury car owners swear by petrol engines and wouldn’t even consider opting for diesel instead. Let’s take a look at the features of both these types of cars, diesel and petrol, to see which is more ideal for a potential buyer.
One of the biggest problems with the initial diesel engines, refinements in the engineering has cut these down by a huge margin. It needs to be understood, however, that every car is unique. While most diesel engines do rank a higher noise, vibration, and harshness (NVH) levels than petrol cars, luxury cars are slightly different. While their noise levels on the outside might be higher than petrol engines, car cabins have come a long way. There is hardly any palpable difference when inside a petrol driven luxury car’s cabin as versus a diesel driven luxury vehicle’s cabin. It would still be practical to look up your desired car’s NVH levels before you buy it, in case you are buying a diesel car.
While both diesel and petrol cars have their own segments where they are powerful, there are certain starkly differentiating factors. Petrol cars would have a quicker pick-up because of their linear power delivery, while in diesel cars the initial response time is a little slower and the engine takes time to build up the rpms. In other words, while your petrol car will have better horse power, its diesel counterpart will offer much better torque. For those demanding a swift response from their car, a petrol engine might be the best deal. If you love a powerful engine which may not have the initial thrust, then a diesel engine could be your ideal machine.
While this might seem like a silly thing to be worried about when investing in a luxury car, it still holds great importance when it comes to car’s resale value. Diesel cars undeniably have the better mileage of the two. Add to it the fact that diesel is cheaper than petrol, and this whole point goes in favour of the diesel engine cars.
Servicing your car and maintaining it in optimum condition is one of the most important things as a car owner. This is also a hefty added cost to the already expensive vehicle you have invested in. Servicing diesel cars is always more expensive than petrol cars. Add to it that the diesel cars are more expensive than petrol cars, and suddenly the mileage and fuel price do not look that appealing.
Both variants have their pros and cons, but it is up to the buyer to put them into account and make the decision after careful consideration.
