The Royal Automobile Club has crowned 91-year-old renowned historian Karl Ludvigsen’s life work as its 2025 Motoring Book of the Year.
Power Unleashed: Trailblazers who Energised Engines with Supercharging and Turbocharging, published by Evro Publishing, is a three-volume, 665,000 word work charting the evolution of forced induction in aircraft and automobiles. It’s the culmination of studies made my Ludvigsen over the last six decades, explaining how these power-boosting technologies transformed Grand Prix racing, Le Mans, and everyday motoring.

Upon accepting the award, Karl Ludvigsen said, “It’s deeply gratifying to see Power Unleashed recognised in this way. Forced induction has fascinated me since I was a student engineer in the 1950s, and this project represents a lifelong journey of discovery. I hope readers will share my admiration for the brilliant minds who turned air and pressure into power.”
