Our verdict
The BMW 118i has a three-cylinder turbocharged 1.5 litre engine, with direct fuel injection. Such an arrangement might in the past have resulted in high particulate emissions but the gasoline particulate filter takes care of such matters in the BMW. The car scores well in the Clean Air Index but is let down by emissions of ammonia, NH3. This pollutant is not regulated by legislation but in Green NCAP's tests it limits the car's scores. Energy efficiency is where the BMW scores best, with a index value of 5.6. Control of greenhouse gases is also good and the index of 4.7 gives an average just below what is needed for three stars. As it is, the BMW 118i emerges from Green NCAP's tests with a very creditable 2½ star rating.
