Radial Motion
Radial Motion started a project back in 2017 to develop radial aircraft engines but soon discovered that they could be used for automotive applications as well. Soon after, this radial-powered Porsche 356 came to life, and things have never been the same since.
"It was designed as an airplane engine, but early on we realized that with a few minor changes it could fit into a car. That made testing prototypes a lot easier and safer, and also turned out to be a lot of fun," said Nick Mebberson, director of Radial Motion.
The company will initially offer two engine options for aircraft or automotive use: a naturally-aspirated 2.0-liter, and a slightly more powerful 2.1-liter, with forced induction versions in the works. Power output from these engines is around the 200 horsepower mark, making it a fun replacement in the lightweight 356.
