1939 Lincoln Model K, the “Sunshine Special”
The first modern presidential limo arrived during the presidency of Franklin D. Roosevelt, as his 1939 Lincoln Model K, known as the “Sunshine Special,” was the first presidential vehicle whose design was dictated by the Secret Service. Before this, presidential vehicles were delivered pretty much stock. This change to safer executive vehicles is likely due to the fact that three American presidents had been assassinated in the previous 75 years (Lincoln, Garfield, and McKinley), plus an unsuccessful assassination attempt on FDR in 1933.
Two sets of changes were made to the “Sunshine Special.” Due to aesthetic considerations, the top of the automobile was lowered by three inches in 1941. Inch-thick cabin armor, flat-proof inner tubes, a radio transceiver, a siren, red warning lights, and a submachine gun compartment were added to the automobile in 1942, following the attack on Pearl Harbor. After the second set of modifications, the car weighed 9,300 pounds and was six feet longer.
In addition to the famous Model K, there were Packards in the presidential fleet during FDR’s presidency. They included an armored 1939 Packard Twin-Six convertible sedan, a phaeton, a sedan limousine, a convertible sedan, a Super Eight touring limousine, and a Super LeBaron touring limousine.
