1931 Duesenberg J Murphy Convertible Coupe at Pebble Beach

Written by Ken Altes

Been to the Pebble Beach concours show in California three times in my life, each a peak experience.  This 1931 Duesenberg J Murphy Convertible contributed to my elation:  The Model J was the fastest and most expensive American automobile on the market. The legendary race-based straight eight had double overhead cams, four valves per cylinder, managing its 420 cu. in. with a 5.2:1 compression ratio into producing 265 hp at 4200rpm.  With a wheelbase of 140+ inches, this car could reach 120 mph and 94 mph in second gear. The next year, the SJ supercharged model was introduced, making 320 hp, and the SSJ 400 hp.
