Petrol Green Cars - See All Sub 100g/km Petrol cars


Petrol engine cars are the most common car available.  They are generally cheaper than their diesel or alternative fuel counterparts to buy.  Petrol powered cars release carbon dioxide into the atmosphere and burn non-renewable energy sources.  We all know this is bad for the environment but there are obviously some petrol cars which are less harmful (greener) than others.


The most efficient petrol cars return the best miles per gallon (mpg) of fuel and therefore produce the lowest CO2 emissions.  These are usually the smaller super mini's as they are lighter and therefore have smaller engines.  These cars are usually the cheapest Green Cars to buy and running cost are low.  Concessions are made with lower road tax rates for producing less harmful emissions and they are usually cheaper to insure and you will notice savings on fuel because of their efficiency.


Below you'll find a selection of petrol cars grouped by CO2 emissions.
