Volkswagen said Wednesday that it initially overestimated the number of cars affected by false emissions data. Only 36,000 vehicles were affected, the auto maker now says, instead of the 800,000 predicted earlier. “Following extensive internal investigations and measurement checks, it is now clear that almost all of these model variants do correspond to the CO2 figures originally determined,” the company said. As The financial effect on the brand could be far less than the more than $2 billion originally anticipated.
