Is the car you're looking to buy suitable for your needs? It may sound like a simple question - but it is so easy to be distracted by impractical cars when you're looking for a new car. Prioritise your needs. Is it space or speed? Looks or practicality? There's no point buying a sports coupe if you want to transport a family of four. Likewise, why buy a big clumsy off-roader if you're a city dweller? Why consider mileage as top priority if you travel less than 10km a day? Petrol or diesel? To answer these questions, and make your buying and selling experience as easy as possible - read on - we've compiled the guide that should provide the answers to all your questions.
Both petrol and diesel engines have their advantages and disadvantages. The gap is narrowing day by day so you can choose either on the basis of your needs.
Diesel engines used to be slow and noisy, but the latest diesel engines are as refined as petrol ones. Now diesel engines are fitted in a number of high-performance models also. Diesel engines emit less carbon dioxide, so they are better in terms of pollution. However, diesel engines tend to pump out more particulates, which are associated with smog formation, respiratory and cardio-vascular illness. Increasingly, diesel engines are being fitted with particulate filters, but this is by no means widespread at the moment.
Petrol engines are getting cleaner and more economical, too. Direct-injection technology now features in a number of models. Performance-minded drivers still tend to opt for petrol cars, though many diesels can accelerate faster than petrol equivalents at speeds from 50-80kph - a more useful advantage in everyday driving.than a quick 0-60 standing-start time. The prices of new diesel cars are usually slightly higher than for similarly-specified petrol models, but they have better resale value.
Diesel is only three quarters the price of petrol and is therefore easy on the pocket. Diesels also travel further on a litre of fuel compared to their petrol counterparts. However, bear in mind that a diesel car makes financial sense only if your annual mileage is more than 13,000-15,000km. If your annual mileage will be less than that, opt blindly for a petrol. If your usage is less than 12,000km annually never think diesel.
