New “impossible to cheat” emissions rating system launches

A new emissions measurement system that accurately steps as well as tracks real-world exhaust emissions of nitrogen oxide (NOx) has compiled emission records from 750,000 cars in Europe over the last decade.
Researchers from the FIA foundation as well as the international Council on clean transportation (ICCT) have now released their findings from the last decade.

Dubbed The real urban Emissions initiative, or true for short, the research includes data from Euro 3, 4, 5 as well as 6 cars – essentially cars made because the year 2000.
• Euro 6 emissions standards: what do they imply for you?
The initiative places cars into three groups based on their NOx emissions.
• Green: for cars with typical NOx emissions that stay below 90 mg/km (milligram per kilometre) over a broad range of driving conditions.• Yellow: cars with typical NOx emissions between 90 as well as 180 mg/km over a broad range of driving conditions.• Red: cars with typical NOx emissions that stay above 180 mg/km over a broad range of driving conditions.
For comparison, Euro 3 limits (applicable for cars sold from 2000 to 2005) allowed petrol cars to emit 150mg/km of NOx, as well as diesels to emit 500mg/km. Euro 6 limits decrease those levels to 60 as well as 80mg/km for petrol as well as diesel cars respectively.
