Grinnall is a British specialist vehicle maker founded by engineer Mark Grinnall, best known for Triumph TR7 and TR8 conversions before developing lightweight three-wheeled sports vehicles such as the Scorpion. Public Grinnall branding has historically focused on the company name rather than a complex pictorial emblem, reflecting the small-volume, engineering-led character of the business.
The marque's identity is closely associated with British kit-car and specialist sports-car culture, where direct name recognition, lightweight construction and visible mechanical performance matter more than mass-market badge symbolism.
