Ford Puma
1.0 EcoBoost Flexifuel Ethanol Mode E85 FWD manual
Tested here is the Ford Puma, a compact crossover car, equipped with a 1 liter direct injection turbo engine. This car can be run on a flexible mixture of petrol and ethanol, from pure petrol to almost pure ethanol. Green NCAP investigated the environmental performance of the vehicle in two modes – a standard petrol mode with E10 and E85, a mixture of 85 vol.-% ethanol and 15 vol.-% petrol. Using E85 as fuel, the Puma delivers excellent performance after exhaust treatment. However, the additional stability of the Cold Ambient Test and On-Road Heavy Load Drive presented a major challenge and the final Clean Air Index dropped to 5.3. Improved control of ammonia and particles will boost results. In the Cold Ambient Test, the car exceeded the limits for non-methane hydrocarbons (NMHC), NH3, CO, and will soon do so for the particle number. On the plus side, NOx emissions were low in all tests. A higher amount of E85 fuel is needed to deliver the same amount of energy as gasoline. With an index of 5.3/10, overall energy efficiency is moderate and, at 6.3 l/100 km on a relaxed, low-load eco trip, slightly better than standard petrol mode. The big advantage of the ethanol (E85) mode is in the reduction of greenhouse gases. Puma is able to keep the tailpipe emissions of laughing gas (N2O) and methane (CH4) low. The usual low value of CO2-equivalent allows the E85-operated Puma to collect 6.9/10 points in the Greenhouse Gas Index, better than the 3.7/10 in standard E10 petrol mode. With a Weighted Overall Index of 5.8, the ethanol (E85) powered Ford Puma receives 3 Green stars and could achieve more if Clean Air performance challenges are addressed.
