Comments

In general, the Prius does a good job of controlling pollutant emissions, even when driven in petrol mode. However, the car tested by Green NCAP was not equipped with a gasoline particulate filter (GPF) and particulate number was somewhat elevated in the cold ambient temperature test. Green NCAP is informed that current production vehicles are equipped with a GPF.

Comments

The Prius PHEV performs extremely well in this part of the assessment, with an average consumption of just 4.8 l/100 km in petrol mode. In its mainly-electric mode, energy consumption is modest although, even in this mode, there was some consumption of fuel.

Comments

Emissions of the unregulated pollutants N2O (laughing gas) and CH4 (Methane) are vanishingly small, and those of carbon dioxide (CO2) are low, giving an index of 7/10 in this part of the assessment.

Our verdict

Toyota has been committed to electrification for many years and, in 1997, the Prius became the earliest hybrid vehicle in mainstream production. Toyota's experience in the field has paid off and the plug-in hybrid version of this, the fourth-generation Prius, impresses on many levels. Pollutant emissions are well controlled and the values recorded here would be improved by the gasoline particulate filter fitted to current production cars. Energy efficiency is extremely good, the dual motor generator drive system, powered by an 8.8 kWh lithium-ion battery, interacting well with the 1.8 litre petrol engine, giving an index of 8.3 in this part of the assessment. Overall, the Prius PHEV shows what can be achieved by a well-engineered plug-in hybrid, and emerges from Green NCAP's tests with a worthy 4 star rating.
