A new report from the Royal Society of Chemistry and Physics says petrol engines are more expensive to produce than diesel and that they require less maintenance.
According to the report, the cost of petrol engines ranges from £1,400 to £1.50 per kilo, while diesel engines cost around £1 a litre.
The report also says that the production of diesel engines has dropped by around 30 per cent since 2001, while the production costs of petrol have gone up by 60 per cent.
It comes as the Government plans to slash fuel prices by up to 25 per cent over the next five years, and also announced a raft of measures to cut carbon emissions.
More: The RSP said that despite the high price of fuel, it is the best way to cut emissions.
The report notes that a reduction in carbon emissions is a major factor behind the economic benefits of fuel-saving technology.
Dr Philip Smith, a researcher at the Royal Institute of Technology, said: “The UK is on track to meet its 2050 target of reducing CO2 emissions by 27 per cent below 1990 levels by 2030.”
We can’t do it on the cheap.
We need to make the fuel and the technology cheaper.
