Packard Model 30 (series U)

The Packard Model 30 frequently also called Model U, was a four-cylinder car built in several series from 1907-1912. Together with the smaller Model 18 (1908-1912) it was Packard's last four-cylinder automobile. Model 30 was Packard's lone offering for 1907 and 1908. It established Packard as a luxury car maker.

Model history

The Packard Model 30 was a four-cylinder car with both closed and open bodies. Prices at introduction started with $4 200 for open models and went up to $5 500 for the limousine and $5 600 for the landaulet.[1][2] A 1911 Four-door Landaulet cost $5,750.[3] Standard equipment included oil lamps, a tool kit, and two extra demountable rims. The closed cars also included speaking tubes, adjustable ventilators and a dome light that had a separate battery. There was a speedometer and an air-pressure gauge. Wheelbase was 123 1/2" for the standard chassis.

Engine and drivetrain

The Packard Model 30 had a water-cooled, 4-cylinder, T-head engine delivering 30 hp (N.A.C.C.) at 650 rpm.[3] displacing 431.9 cubic inches (7078 cubic centimeters)[1] with a bore 5 in. (127 mm) and a stroke of 5.5 in. (139.7 mm)[2]

A plate clutch was blocked with the engine. Power was transmitted by a long shaft with universal joints to the 3-speed sliding-gear manual gearbox with reverse. This was located in a housing at the rear axle which also contained the differential. The car used shaft drive from the beginning although many other high-powered cars at this time relied on double-chain drive.

In 1909, redesigned linkage in the transmission made it possible for the reverse gear to be activated with the regular gear-shift. Since 1904, all Packards had had a separate lever for the reverse gear.[4]

Chassis

The ladder-type frame used semi-elliptical leaf springs front and rear. Steering included now ball bearings instead of roller types, and featured a Pitman arm in front of the front axle.[1][2]

Brakes were mechanical on the rear wheels only, working either by pedal (external contracting) or lever (internal expanding). Following the Owner's Manual, each was sufficient for stopping under normal conditions.[5][6]
