My previous research found that the number of diesel cars licensed in London rose from 601,456 in 2012 to 774,513 in 2015, an increase of nearly 29%. The number of petrol vehicles fell over the same period, from 1,901,127 to 1,797,099, leaving diesel with a record high percentage of the market, at 29.4%. How many diesel cars and petrol cars do you estimate are owned in London now? What is the percentage increase from 2012 and 2015?

Society of Motor Manufacturers & Traders data for the number of passenger cars registered to postcode areas in Greater London indicates a total of 667,307 diesel cars in 2012, growing to 867,426 in 2015. The number of petrol cars fell in the same period from 2,122,872 to 2,053,332.

The most recent figures available, from the end of 2017, indicate a total of 953,911 diesel cars and 2,014,819 petrol cars. That equates to an increase in diesel cars of 43 per cent since 2012 and an increase of 10 per cent since 2015.

Note that these figures include diesel and diesel hybrids combined, and we do not have data on the split between hybrid and non-hybrid vehicles. The figures for petrol include LPG bi-fuel, hybrids, plug-in hybrids and range extended electric vehicles. Again, there is no breakdown of the petrol engine category. Battery electric vehicles are not included.
