The "greener" cars according to Green NCAP
How really emit and consume cars on the market? This is revealed by tests carried out both in laboratory and traffic by Green NCAP, the new consortium created by the International Automobile Federation and Euro NCAP to promote greener and more efficient cars in terms of fuel and energy consumption.
For now, Green NCAP considers only the energy used while driving (‘tank to wheel’), but in time, well-to-wheel and ultimately the whole life-cycle will be considered, including the energy used to produce the vehicle, the energy it consumes in its lifetime and the energy needed to scrap and recycle its parts.
For this Green NCAP’s first round of tests twelve cars have been rated: the Hyundai Ioniq and BMW i3, both electric vehicles, achieve a maximum five-star rating; the VW up! GTI gets a creditable four stars; BMW’s X1 2.0d and the Mercedes-Benz A200 are both awarded three stars; the Ford Fiesta 1.0 EcoBoost is rated as two stars in its latest guise, and a one-star rating is given to the Audi A7 50 TDI, the Volvo XC40 T5 and the Subaru Outback 2.5.
Three cars – the VW Golf 1.6TDI, the Fiat Panda 1.0 and the previous level Ford Fiesta 1.0 EcoBoost - get zero-star ratings. All three of the zero-star cars are approved to Euro 6b emissions standards, still valid for models introduced before September 2017. However, from September 2019, all cars will have to meet the tougher standards of Euro 6d-temp and updated versions of these cars will be rated in the next round of tests.
For now, electric cars offer consumers the greenest option when buying a car. However, Green NCAP will soon include driving range in its assessment, and ultimately, will look at the whole life-cycle of the vehicle, which may close the gap between electric cars and those powered by fossil fuels.
