List of Fictional Brand Names in Turtledove's Work

The works of Harry Turtledove feature many real-world product brand names and incorporate them into the story - e.g., McDonald's, Coca-Cola, Walgreen's, etc. However, they also feature numerous fictional products, particularly in alternate history stories, or works set in the future. While some of these fictional products are crucial to the plot of a given work, most are passing references meant simply to provide momentary background color to a fictional world, often serving as inside jokes.

The Disunited States of America
Soft drinks:
 * 6+, described by Beckie Royer as a fizz, lemon-limey, on the order of Sprite (an OTL brand which apparently exists in this alternate). The name seems to be a double reference to the real-world brand 7 Up and Turtledove's own science fiction story "6+", part of the Noninterference series.

Automobiles:
 * Pegasus, mentioned in passing.
 * Hupmobile, mentioned in passing.
 * Lancelot, mentioned in passing
 * Vance, described by Justin Monroe as being as popular as Chevrolet in the home timeline.
