Power Unleashed

Award-winning author Karl Ludvigsen takes the reader behind the scenes of the roller-coaster ride of supercharging, turbocharging and even more exotic power-boosting inventions throughout automotive and aviation history. Supercharging in all its forms is the most exciting feature ever created to go under the bonnet of a motor car. Blowers were rare yet highly desirable devices in their early heyday of the 1920s and ’30s, an era in which compressors graced supremely glamorous and race-winning cars. They also won respect from aviators eager to exploit high altitudes.

Prolific use of forced induction in the air in World War II brought forth the many engineering geniuses who populate these pages. Having seemed abandoned on land, supercharging found new acolytes who perfected blowers for road and track. They rescued the turbocharger to open new avenues for high-pressure boosting in the 1970s and ’80s. Into the 21st century turbocharging has found its way into more and more cars to enhance both performance and fuel efficiency.

Power Unleashed is a three-volume work of astonishing depth and detail. Greatly respected for his ability to communicate information while telling a compelling story, Karl Ludvigsen explores the global saga of supercharging and turbocharging. Complete with reader-friendly technical descriptions and magnificent illustrations, he introduces the fascinating individuals who bet their businesses on boosting. This is a landmark work in the histories of the automobile and aeroplane

Karl Ludvigsen is widely known and respected in the automotive world for his research and reporting on all aspects of motoring and motor sports. This has come about through his studies of engineering and industrial design as well as his senior positions with GM, Fiat and Ford and his leadership of a motor-industry management-consulting company. 

Active for over 70 years as an author and historian, Ludvigsen first studied supercharging applications in 1955 while attending Brooklyn’s Pratt Institute. He has meticulously researched the subject ever since, building upon a landmark piece published by Automobile Quarterly in 1970 entitled ‘The Origins of Supercharging’, for which he interviewed many pioneers of the art. As author, co-author or editor Karl has some six dozen books to his credit, among them titles about engine topics such as The V12 Engine, Classic Racing Engines and Bentley’s Great Eight. Ludvigsen has received 73 awards for his high standard of writing and research. He lives in Suffolk.
