Correction
On the precision of the ultraviolet-blocking figure in our Audi Q7 coverage.
An earlier version of our Audi Q7 coverage said the panoramic roof's glass blocks more than 99 percent of ultraviolet radiation. Audi gives the figure to the decimal: more than 99.5 percent. The dropped half point is the half the maker bothered to measure, and it was not ours to round away. The record is corrected.
