Green NCAP determines particulate number using industry-standard measuring equipment, which can detect particles larger than 23 nm.  There is some evidence that cars which perform well when measured in this way may in fact be emitting large numbers of much smaller (sub 10 nm), and very harmful particulates.

Good or adequate control of pollutant emissions when running in gas mode is let down by extremely poor control of particulates when the car is switched to petrol. As a result, the score is penalised and the Clean Air Index of 5.5 limits the car to a two-star overall rating.

Our verdict

The Panda, tested previously by Green NCAP in its Euro 6b petrol form, is assessed here as the Euro 6d-temp CNG/petrol bi-fuel variant. The car has a 12 kg CNG tank and a 35 litre fuel tank, meaning that it will spend much of its time being driven on petrol, in addition to its compressed natural gas (CNG) ‘primary’ fuel. When running on gas, pollutant emissions are generally well controlled. However, when the vehicle is run on petrol, and with no gas particulate filter, emissions of particulates are extremely high, over twenty times higher than CNG mode in the case of the cold test. Even in CNG mode, hydrocarbon emissions are above Green NCAP’s poor-performance limit in the high-load test. As a consequence, the Clean Air Index is a modest 5.5, limiting the overall rating to two stars. Energy efficiency is marginal, especially in the high load test, and the average fuel consumption in gas mode is 4.2 kg/100 km. FIAT expect the car to be used predominantly in gas-mode. However, the relative sizes of the CNG and petrol tank invites drivers to use both fuel modes, while FIAT has optimised the car only for one.
