Jupiter 8

The Jupiter 8 was a two-seat sports car marketed to the inhabitants of the planet 892-IV. It was first viewed by the crew of the USS Enterprise (NCC-1701) in the television news footage upon entering orbit of the planet.

Described as "Royal Comfort" and "unexcelled in its field," it had a conventional internal combustion engine with 456 horsepower, a super-flow automatic transmission, a super-glide suspension system, and super-grip white sidewall tires. Upon reading an advertisement in The Gallian, which described the Jupiter 8's features, the Enterprise landing party determined that its power source was, in part, the cause for the planet's smog.
