- Lower power to weight ratio then petrol engines, due to the increased internal component strength- to cope with the high pressures.
- Lower rev band range compared to petrol engines, although turbo/ super charging has helped to combat this in the last decade- again caused by heavy internal components to a certain degree.
- Normally noisier and rougher in operation compared to petrol counter parts, although diesels are almost on par with technological advancements with modern applications- especially if we look at German car manufactures for example.
- More expensive to purchase and run compared to petrol alternatives, due to increase in stronger components and more regular service schedules- higher mileage use will offset this with fuel savings, but anything say below 12,000 miles a year- petrol will be a safer bet.
- Diesels have had some success with racing series, but from an overall power to weight point of view, I assume petrol to be more competitive at this stage in time- as a larger engine needs to be deployed compared to a smaller petrol for similar overall BHP, but Diesels do produce more Torque especially when deployed with turbo charging.
