Celebrate the rebirth of the world's most stunning high-performance automobile. Porsche made history when it brought turbocharging to the racing world in the form of the 917. When strict regulations regarding engine displacement took away the option of bigger engines, manufacturers turned to forced induction. In its wildest trim, the original 12-cylinder turbocharged Porsche racing engine yielded as much as 1,400 horsepower! Porsche's official philosophy was that racing cars must have a connection to street cars, so it was preordained that Porsche would eventually produce a turbocharged version of its air-cooled flat-six cylinder engine. The resulting 930 Turbo appeared in the spring of 1975 in Europe. Acceleration from 0 to 100 kilometers per hour took a scant 5.5 seconds, and its top speed was 155 miles per hour. The Turbo's distinctive rear wing let the world know that this was something very special. It was nothing less than the rebirth of the high-performance automobile. At a time when the big-block engines in America's so-called "muscle cars" were putting out 180 horsepower and the engines in exotic supercars weren't much more ambitious, the lightweight Porsche was a genuine rocket. Porsche Turbo: The Inside Story of Stuttgart's Turbocharged Road and Race Cars celebrates Porsche's five decades of turbocharged supercar performance, both on the track and on the street. It covers all of the major racing cars as well as the turbocharged street cars, including the 930, 935, 924, 944, 968, 911, and Cayenne Panamera. Don't let this one fly past you! "For those looking for a book focused on Porsche's turbocharged racing, and street cars, veteran motoring author Randy Leffingwell has put together a fascinating tome in Porsche Turbo: The Inside Story of Stuttgart's Turbocharged Road and Race Cars that covers everything the company ever put a turbine on, from the sports cars to the Panamera sedan, Cayenne, and Macan sport utility vehicles. Leffingwell backs up his well-written text with a plethora of photographs, factory archive material, technical, and conceptual drawings.

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 Po rsche 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 Porsche Panorama . 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.
