Key points
- There is a massive gap between laboratory emission results and actual pollution levels during real-world driving, especially for diesel cars.
- Many manufacturers used optimization strategies to pass laboratory tests, which did not reflect normal driving conditions.
- The use of prohibited defeat devices to manipulate emission controls was not adequately detected or prevented by authorities.
- New, more realistic testing procedures (RDE) were introduced to close the gap between lab and road results.
