Petrol is generally quicker to accelerate from slow speeds so is good for overtaking slow vehicles. However, diesel engines should run at high speeds for 30+ minutes to allow exhaust temperature to rise and ‘burn off’ excess soot, which is not possible on short journeys. The price of a petrol is normally lower than an equivalent diesel, where higher purchase price can lead to higher insurance premium.
Diesel’s greater torque make it more relaxing to drive with fewer gear changes. Its weight adds more stability and offers a higher legal towing limit. They are also more efficient than petrol so give better MPG.
It would take 50 new cars today to produce the same amount of pollutant emissions as one vehicle built in the 1970’s.
