I found this video really interesting. Jay Leno bought a Rolls Royce based project, and spent around 20 years restoring and rebuilding it. It has many modern features to make it safe to drive. The Merlin engine was the one built by Eolls Royce, andit was used in the Spitfire aircraft in World War II. It is worth watching the video for the technical discussions about managing the power output from the engine, as well as the historical notes.
