In page Diesel emissions scandal:

"

The 2015 scandal was likely caused by the increasingly strict standards set, paired with the lack of technology to meet these requirements.[citation needed] Moreover, another possible reason for this scandal outbreak is cost. In order for automakers to comply with these standards, they must spend from $800 up to $3,000 more per vehicle.[4] Volkswagen confessed that they could not comply with the policies in the amount of time they had when the standards became more strict in 2005.[citation needed] After much analysis of the Volkswagen company, the rigging was allowed for so long due to failing internal policies.[citation needed]
