Packard Twin Six
The Packard Twin Six refers to a series of V12-cylinder automobiles that the Packard Motor Car Company in Detroit produced between the model years 1916 and 1923. The model was revived in 1932, but was renamed Packard Twelve the following year .
1916-1923
After Packard had introduced the first six-cylinder models in 1913, they took another step towards luxury cars and introduced the first twelve-cylinder in 1916.
In contrast to the "Single Six", the car was christened "Twin Six" and received a V12 engine with a 60 ° cylinder angle, side-mounted valves, 6821 cm³ displacement (bore × stroke = 76.2 mm × 127 mm) and an output of 88 hp (64.7 kW) at 2,600 rpm. The engine power was passed on to a manual three-speed gearbox via a multi-disc clutch, which was installed at the front, directly behind the clutch. The previous models had their gearbox installed on the rear axle. The gear lever was still on the far left. The mechanical brakes only worked on the rear wheels.
The Twin Six was available with two different wheelbases: The 1-25 model had a 3175 mm wheelbase, the 1-35 had 3429 mm. Both chassis were available with a wide variety of closed and open bodies for 3–7 passengers.
In 1917 the models were slightly revised and were now called 2-25 and 2-35. They received somewhat smaller spoked wheels (35 "instead of 37") and removable cylinder heads. In the two following years, the engine output was increased to 90 hp (66 kW) (models 3-25 and 3-35), otherwise the vehicles were built unchanged.
After the First World War , the production of the short chassis was stopped in 1920. The 3-35 model continued to be built until 1923 and then discontinued without a successor. A total of 30,941 vehicles of this type were produced.
The first American president to drive to his inauguration in an automobile was Warren G. Harding in 1921 . It was a Packard Twin Six.
1932
In 1932, in the 9th series, Packard again introduced a twelve-cylinder as the largest model. This vehicle was also available with two wheelbases. The chassis with a 3619.5 mm (model 905) or 3746.5 mm (model 906) wheelbase were adopted from the eight-cylinder models.
The V12 engine also had little to do with that of the predecessor model of the same name: the cylinder angle was 67 °, the bore was 87.3 mm and the stroke was 101.6 mm. This resulted in a displacement of 7,300 cm³. The engine developed 160 bhp (118 kW) at 3,200 rpm and the engine power was passed on to the rear wheels via a two-disc clutch and a manual three-speed gearbox (with a gearshift lever in the middle of the car). All four wheels were now braked mechanically.
This Twin Six, which was also available with various bodies for 2 - 7 passengers, only lived for one model year. In 1933, the almost unchanged Packard Twelve replaced it after only 549 copies were built.
