Engine size is typically related to both fuel consumption and vehicle exhaust emissions. Generally speaking, larger engines consume more fuel and generate more greenhouse gases and air pollutants per kilometre travelled than smaller engines.
In 2007, the engine size of the average light vehicle in New Zealand continued to increase despite rising fuel prices. The average light-fleet engine size in December 2007 was 2.26 litres, up from 2.24 litres in December 2006. The average engine size of the light fleet has increased by 8 per cent since 2000.
