Correction
On the AP styling of a V-6 engine designation in our Audi Q7 craftsmanship column.
An earlier version of our Audi Q7 craftsmanship column rendered the 2.9-liter engine as a "V6." AP style sets the hyphen: it is a V-6. The mark is not ornament. It binds the configuration to the cylinder count, so the reader sees one designation and not two stray characters jostling on the page. We omitted it. The record is corrected.
