Grinnall

Grinnall is a small British specialist vehicle manufacturer best known for its Scorpion series of three- and four-wheeled sports vehicles. The business grew from the efforts of Barry Grinnall, who established a specialist engineering and vehicle-modification operation that evolved into manufacture of bespoke and kit-style sports cars and trikes. Grinnall vehicles emphasize lightweight construction and motorcycle-derived powertrains in three-wheel layouts, with later cars expanding into four-wheel models. There is limited public documentation on a formal historic logo evolution; the brand is primarily recognised by the Grinnall name and model badges on its distinctive Scorpion machines.
