Randy Leffingwell wrote his first book, American Muscle, while still on staff at the Los Angeles Times. The book examined Times' publisher Otis Chandler's growing collection of muscle cars. American Muscle published in September 1990, jump-started a love of book creation that ultimately led Leffingwell to leave the Times in 1995. By then, he and Motorbooks had published Porsche Legends, and six other books.

Since 1990, Leffingwell has authored more than 60 titles, most of them automotive-oriented. Over 30-plus years, these include a dozen Porsche titles ranging from general overviews--Porsche 75 Years: Expect the Unexpected, and The Complete Book of Porsche 911--to deeper explorations in Porsche Turbo and Porsche 911: 50 Years. During this time, he has regularly traveled to Germany to continue his research regarding Porsche's history. To date, Leffingwell has interviewed more than 200 Porsche engineers, stylists, model makers, racers, and managers.

While he has tackled other subjects including John Deere tractors, Harley-Davidson motorcycles, and West Coast lighthouses, Leffingwell admits he is almost addicted to the Porsche story. In addition to his book work, he is historical editor for 000 magazine and PorschePanorama. And for the past decade he has been researching and writing an encyclopedic history of Porsche's motorsports endeavors.

Leffingwell lives near Santa Barbara, California.

"Porsche 911: 50 Years is above all a celebration of a peculiarly individual car which in a rational world would never have existed and yet survived and prospered through a half century, evolving and adapting but never losing its highly distinct character. No other brand has ever managed this and Leffingwell's achievement is the focus he brings to this compelling story. Some of the face-to-face discussions the author was able to hold with current Porsche movers and shakers would have been impossible only a few years ago and this greater openness has extended to the company's image collection: the book is illustrated by a superb selection of previously unseen Archive photography. Leffingwell has created a splendid monument to the Porsche 911, which more than just the definitive sports car, has defied conformist pressures to become a symbol of endeavour and excellence." - Total911.com

'an exhaustive history of the 911... I wholeheartedly recommend it.'

"Originally published in 2013, Randy Leffingwell's celebration of one of the world's premiere sports cars, is still a top seller more than 3-years later."--FLATSIXES.com
